Trying to design a great WLED board 🌈🦄🦃

While waiting for the turkey to finish brining, we're designing a board for using WLED - and we want to make like the bestest board in the whole world.

Our resident mermaid, firepixie

, makes a lot of projects with WLED, and she loves it! So, how can we make something that will be powerful but not too bulky? Here are some things we're thinking about as the design starts to congeal like cranberry sauce:

Power via USB Type C PD with a slide switch that selects between 5, 12, and 20V (24V pixels can usually run fine at 20V) OR via a 2.1mm DC jack. With ideal diodes, it's good for up to 5A from either.

ESP32-Mini module with built-in or optional wFL antenna port. The classic '32 has broad support, even if we'd prefer the 'S2 or 'S3.

There are three output signal terminal block sets, with power and ground for each. They'll be level-shifted to 5V.

Built in I2S microphone (we're still pondering this one).

Stemma QT I2C port to connect external sensors/OLEDs/etc.; separate analog/digital input JST port.

1.3"x1.75" / 33mm x 45mm size with mounting holes.

Anything we're missing, anything that's extraneous?

setting up an ipod is harder than you fucking think

just spent the last life four+ hours setting up this ipod classic 4th gen. here's a summary of all the problems i ran into:

(1) ipod had files in it. they appeared as gray and un-editable on itunes, so i thought reseting the ipod to factory would be the fastest and easiest solution.

turns out the last step of the process is connecting ipod to a wall power source. i do this. nothing happens for at least an hour. ipod is stuck in "connect to the wall" icon screen no matter what i do. the internet says it needs to connect with an actual apple firewire wall connector, which i do not have. tried using my ipad's charger with a usb-to-usb-c adapter that i own. didn't work. eventually figured it out the problem had to do with the amps it needs to get defibrillated. i remember that i own a pretty hefty power bank with a 5v/2.1a output. it works. ipod is reset. i have a nice fun time adding the 6 or so songs i have downloaded on my computer (:

(2) i had downloaded soulseek a while ago and gotten frustrated with it but decided to give it another spin since piracy experts on reddit sing it many praises. it seems to have a heavy culture of egalitarianism: a pop up window informs you that a lot of people's download's are restricted only to other people sharing files.

__(2.1) it prompts me to enter my account and password but i don't have one. there isn't an immediatly visible 'create account' link. i google this. eventually i find this soulseek forum where a ton of normies are asking questions pretty regularly. excellent. i search my problems and someone else has already made a post and had the question answered. thank you normies. also: google groups is still a thing???????

the inability to create an account is a weird bug. someone's answer tells me how to circumvent it.

__(2.2) i still can't search for anything. there are no files in this wasteland. i turn on my vpn. put my humble six songs in a folder and share it. voila!!!!!!!

soulseek is actually VERY cool. you can browse other people's music folders, which opens an incredible secret world of possibilities re: finding new music similar to your tastes. EXTREMELY exciting. feels like i'm in a cool secret club of the internet. feels like the old internet.

i download one (1) lana del rey song that's stuck in my head. choose .flac (a lossless audio file) because i want to be fancy.

(3) ...........itunes doesn't read .flac files

__(3.1) searches: what files does itunes read? > which of these files is best for lossless audio? > how do i convert .flac files to itunes-compatible file types? > download foobar2000 > click around till i figure out how to convert .flac files to .wav files.

__(3.2) it works! (: the songs are now in itunes! (:

............but the metadata (album cover, genres, artist, album, etc) doesn't transfer. i don't want to manually input it again. searches: how to keep metadata when converting files? tutorial is slightly different from the version of foobar i have, but i eventually find the setting to keep the metadata.

(4) it works! (:

.............but it won't transfer to my ipod ): i get the message: your ipod can't read this file <- paraphrasing.

okay. searches: what kind of files can an ipod classic 4th gen read? (perhaps they are different from the files itunes can read. this is, after all, the last version of itunes ever released, many years and itunes versions after the ipod classic 4th gen.)

this information isn't in the wikipedia page. this isn't in the ipod wiki. can't even find this model in the official apple pages. it's mentioned in several reviews but it's the wrong model. christ almighty. ok. here it is. found it. allegedly it should be able to read it. ok. why isn't it.

read through forum threads. some people say older ipods get fussy with high bitrates. (search: what is a bitrate? oh ok. higher bitrate > higher audio quality. got it.)

bitrates reccomended by foobar: 180-300something. lossless file bitrate: 2000 and change. hm. surely that's a huge difference.

i convert the .flac file to .mp3 instead.

__(4.1) it works! (: the files are in my ipod! (:

.....but goddamnit, i'm stubborn, and this goddamn ipod is supposed to be able to read apple lossless files (basically a .flac file, but designed to be used with apple products. lol.) i don't want a lameass mp3, i want lossless goddamn quality! even if this brick of an ipod won't be able to play it! it's the principle of the thing!

______(4.1.1) okay. try to fuck around with bitrates in the settings of the apple lossless conversion on foobar. foobar is like "you don't have the right encoder pack, bitch" <- paraphrasing.

oooh. surely, this is the problem. i download encoder pack.

______(4.1.2) foobar is like: "you don't have the right encoder pack, bitch" <- paraphrasing.

me: [crying] but i did.

foobar: bitch.

______(4.1.3) search: why is foobar calling me a bitch? > reddit thread: look closely at the sphynx's riddles three: it doesn't say "you haven't downloaded the encoder pack." it says: you haven't installed the encoder pack. (<- NOT A JOKE.)

go to C: > program files > foobar > find the encoder pack i downloaded > click on all the .exe files. powershell windows appear and dissappear. basically: stuff happened. i'm certian.

_____________(3.4.3.1) i'm STILL getting the riddles three message, but the same reddit thread says: if you know you solved th riddles three, you can just ignore it (: so i do.

__(4.2) .flac files seem to have been successfully converted to apple lossless files !!!!!!!!!!!!!!

....but i am back to "your ipod can't read this shit!!!!!!!!!"

do some more searches > turns out it's a weird itunes glitch. the thing is just moody. try turning it on and off. try disconnecting and re-connecting. try resetting your ipod again.

try uninstalling and installing again.

(5) "iTunes Library.itl cannot be read because it was created by a newer version of iTunes"

.......................to be continued. if i don't kill mysuelf first.

Good news: the PCB bus boards for my new Eurorack case came today!

Bad news: building and installing all of them requires 54 of the little 16-pin box headers, and I only actually have 10 on hand. And while I could order them, I really shouldn't until more money comes in, around about Friday.

At any rate, also included in the shipment were a couple of simple modules from Sourcery Studios: their ASMR (A Simple Mixer, Right?) five-channel mixer and their POW module, which provides power LEDs for each rail, a box header for plugging in modules for testing, and a USB-A jack for powering things from the 5V rail. (It also has a switch I won't be using, as it's meant for a different power setup than the one I'm using.) So I'll probably build those before I get to the actual case build.

a fun fact about me is that our house didn't have a PC until i was about 14 -- and even then, it was shared by the whole family, and didn't have internet access for a while. my dad eventually signed up for AOL around 2001, at which point we were able to surf the web™ via a 56k dial-up connection.

however, we did have internet access prior to that… via our TV:

source: https://web.archive.org/web/20190407175637/https://www.digitalspy.com/tech/cable/a3171/ntl-cr2-interactive/

this gave us a (single, shared) email address, and access to an extremely limited number of websites, such as leisuredistrict or everyoneswelcome.

(as an aside: you could unlock "full" web access by paying an extra £5 per month, which we eventually did… but not before discovering that if someone emailed us a clickable link, we could access that site without going through the "proper" menu option!)

anyway, to compose emails, enter your leisuredistrict password, or write an everyoneswelcome post, you had to use the remote control:

source: https://web.archive.org/web/20190407173228/https://www.digitalspy.com/tech/cable/a3231/ntlhome-digital-interactive-tv/

as you can imagine this was slow and awkward. however, as the image above indicates, you could buy a special keyboard to make things easier. since my dad used to play chess via email (using a physical chess set next to the television), he ended up getting one:

source: https://www.reddit.com/r/nostalgia/comments/hm5pfa/these_ntl_keyboards_i_think_im_on_an_ntl/

as you might have noticed, it has a somewhat strange layout, and doesn't have a wire coming out of the back. that's because this keyboard is actually just a really big remote control; you put 4 AA batteries in the back, and it communicates with the set top box via infrared signals, just like the standard remote control would.

of course, our set top box eventually outlived its usefulness, and all of this stuff went into a storage cupboard, whereupon it was promptly forgotten about… until a few months ago, when i rediscovered the keyboard whilst my dad was clearing out some old things. as you might expect, i saved it from being sent to silicon heaven (where all the calculators go) because i am a goblin who hoards old technology.

i put it to one side for a while, but a few days ago i decided to see if it was still working. it turns out that regular webcams can pick up infrared light, so i put some batteries in it and -- success! -- several white-ish lights were visible in my laptop's webcam app whenever i pressed a key.

as such, i think it would be cool to somehow get this thing working as an actual PC keyboard. i might need to write a custom program to do this, though it seems that it might Just Work.

of course, i'd need some kind of infrared receiver device to do that, and those can be surprisingly tricky to find:

there are plenty of "infrared extender" cables online, but their USB connector is only used to draw power; they don't actually show up as a "device" on your PC.

you can apparently get infrared-receiver-to-headphone jack cables, which you're supposed to plug into a special socket on certain set top boxes… though in theory you could plug them into the microphone input port of a PC and "manually" decode the data signal via software trickery. (disclaimer: i am not an expert on Hardware, so this might be A Bad Idea, but i think that the 5V output by the microphone port would be enough to power the IR receiver…?)

the thing i actually want (an IR-to-USB device) might as well not exist because it is no longer 2005 and no-one on the planet except me gives even half a shit about connecting an IR device to a PC. well, that's not entirely true -- but the things i did find cost £30-£50, which is way above what i'd want to spend on something like this.

eventually, though, i discovered that the magic phrase to search for is "Media Center IR receiver" (or, more simply, "MCE receiver"), whereupon i found someone selling an Acer MCEIR-210 on ebay for just over £10. its due to arrive here within the next few days, so hopefully i can make this somewhat-unusual device function again.

One of the most well-liked Bluetooth speakers available is the JBL Flip 5. It offers excellent sound quality and is portable and small. The speaker not charging is one of the most frequent difficulties consumers experience, nevertheless, just like with any electronic item.  If you’re dealing with this problem and wondering how to fix it, you’ve come to the right place. In this article, we’ll explore some simple solutions to help you troubleshoot and resolve the issue.

Check the Charging Cable The USB cable that comes with the speaker might occasionally be damaged. Your speaker won’t be adequately charged by a subpar USB charging cord. To determine if the issue is with the cable, it is best to test a different or new cable. Take a USB cord from a friend or inquire about a speaker charging cable at an electronics repair shop. If the speaker begins to charge with the new cable, the USB charging cable needs to be changed because it is at fault. In order to prevent experiencing the same issue in a few weeks, it is recommended to replace it with an original cable rather than a third-party one. It wasn’t the cable’s fault if the speaker won’t charge even with a fresh cable, therefore keep the new USB charger for the next step.

Check the Charging Port The JBL Flip 5 speaker’s front panel houses the charging port. There is no protection or door over the charging port to keep out dust. It’s likely that the JBL speaker’s charging connector contains dirt if you used it outside. The speaker won’t charge if there is dirt or dust within the charging port, which prevents the charger from connecting with the speaker. Check for dirt by using a flashlight. Use the flashlight to shine directly into the port to check for debris. Remove any dirt from the interior if there is any. Use a small, soft toothbrush or a toothpick to get rid of the filth. When cleaning the port, you should exercise caution because it is easily damaged. Even if you can’t see any dirt with the flashlight, you should still try to clean it. It’s likely that there is filth within that you cannot see. Try charging the speaker after cleaning the charging port.

Check The Wall Charger Your JBL Flip 5 may not be charging even though the USB cable is working properly, or perhaps both the wall charger and the USB cable are to blame. To see whether this resolves the issue, try a fresh USB cable and wall charger. You ought to select a new wall charger that has the same output power as the old one. It is not advised to choose one with a lower voltage because your speaker won’t charge sufficiently at that rate. The 20W RMS power-rated JBL Flip 5 comes with a 5V/3A wall charger requirement. If the speaker charges using a fresh USB cable and wall charger, the problem is with the wall charger, which needs to be changed. If not, proceed to the following action.

Reset The JBL Flip 5

A software issue could prevent your JBL Flip 5 from charging. A JBL speaker needs to be hard reset in order to solve the majority of software issues. The speaker’s settings will be erased and the hard reset will return the device to its original state.

Turn off your speaker: Press and hold the power button until the speaker turns off.

Press and hold the Bluetooth and Volume Up buttons: While the speaker is turned off, press and hold the Bluetooth button and the Volume Up button at the same time.

Wait for the reset to complete: Keep holding the buttons until the LEDs on the front of the speaker flash. This may take up to 10 seconds.

Turn on your speaker: Once the LEDs stop flashing, release the buttons and turn on the speaker by pressing the power button.

Reconnect to Bluetooth: If you were previously connected to a device via Bluetooth, you’ll need to reconnect your speaker to that device. If restarting your speaker doesn’t fix the issue, there can be a more serious issue that needs additional investigation. But maybe this quick reset will help you resolve the JBL Flip 5 charging problem.

Dry The Wet Charging Port Although the JBL Flip 5 is IPX7 waterproof, the charging connector is still susceptible to being wet. The speaker won’t charge if the charging port is damp; instead, you must first dry it. You can use a hairdryer to dry a damp charging port, just make sure to use the hairdryer at low temperatures. The speaker could be harmed by excessive heat. Use a hairdryer to dry the speaker for about 5 minutes, and then wait at least 24 hours before attempting to charge it.

Different Wall Outlet It’s time to replace the wall outlet if you’ve already changed the USB cable and the wall charger. You run the risk of having a damaged wall outlet when charging your speaker. So, test various charging outlets to be sure.

DIY Smart Home Energy Monitor with ESP32 and Home Assistant

Introduction

Managing energy consumption is a great way to reduce electricity costs and contribute to environmental sustainability. With the help of IoT, you can monitor energy usage in real-time, right from your smartphone. In this guide, we’ll build a Smart Home Energy Monitor using an ESP32 microcontroller, current and voltage sensors (like the ACS712 or SCT-013), and the MQTT protocol for data transmission. This data will be accessible on a mobile app via Home Assistant, allowing you to keep track of energy usage and optimize it effectively.

Project Overview

Objectives

Monitor power consumption in real-time for home appliances.

Display energy usage on a mobile app using MQTT and Home Assistant.

Analyze data over time to make informed decisions about energy usage.

Key Components

ESP32 (or ESP8266) microcontroller: For reading sensor data and connecting to Wi-Fi.

Current Sensor (SCT-013 or ACS712): For measuring current drawn by appliances.

Voltage Sensor: Optional, but adds more accuracy if you want to measure precise power usage.

MQTT Protocol: To send data to Home Assistant for real-time monitoring.

Home Assistant: A home automation platform to display and analyze data.

Part 1: Setting Up the Components

1. ESP32 or ESP8266 Microcontroller

Choose either the ESP32 or ESP8266 microcontroller. The ESP32 has more features and is preferred, but either will work.

Connect the ESP32 to your computer using a USB cable to program it.

2. Current Sensor (SCT-013 or ACS712)

SCT-013 is a non-invasive sensor that clamps around a wire to measure the AC current flowing through it.

ACS712 is a current sensor that can measure both AC and DC current but requires direct connection to the wire, so exercise caution with high voltage.

Wiring for SCT-013

Connect the SCT-013 sensor’s output to an analog input pin on the ESP32.

If you’re using SCT-013 with ESP8266, you’ll need an analog-to-digital converter (ADC) module since the ESP8266 has only one analog input pin with limited resolution.

Wiring for ACS712

Connect the VCC pin to the 3.3V or 5V pin on the ESP32.

Connect the OUT pin to an analog input pin on the ESP32.

Connect the GND pin to the ground (GND) on the ESP32.

3. Voltage Sensor (Optional)

A voltage sensor can be added to measure the actual voltage if you want to calculate power more accurately.

Connect the sensor’s VCC to the 3.3V on ESP32, GND to ground, and OUT to an analog input.

Part 2: Coding the ESP32 for Data Acquisition and Transmission

1. Install the Required Libraries

Make sure you have the following libraries installed in your Arduino IDE:

ESP32 or ESP8266 board support (depending on your microcontroller)

PubSubClient library for MQTT communication

WiFi library for connecting to your Wi-Fi network

2. Set Up the Code

Here’s the code to:

Read values from the current sensor.

Calculate power consumption (voltage x current if you have a voltage sensor, or assume constant voltage).

Publish data to an MQTT broker.

#include <WiFi.h> #include <PubSubClient.h>

// Wi-Fi and MQTT Broker Settings const char* ssid = "YOUR_SSID"; const char* password = "YOUR_PASSWORD"; const char* mqtt_server = "YOUR_MQTT_BROKER_IP";

// MQTT topics const char* topicPower = "home/energy_monitor/power";

WiFiClient espClient; PubSubClient client(espClient);

// Sensor parameters const int sensorPin = 34; // Analog pin for sensor (ESP32) const float voltageCalibration = 230.0; // Voltage in volts (modify as per your region) const float sensorCalibration = 0.185; // Calibration constant for ACS712 sensor

void setup() { Serial.begin(115200); setup_wifi(); client.setServer(mqtt_server, 1883); }

void setup_wifi() { delay(10); Serial.println("Connecting to WiFi..."); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500);

Serial.print("."); } Serial.println("Connected to WiFi."); }

void reconnect() { while (!client.connected()) { Serial.print("Connecting to MQTT..."); if (client.connect("ESP32Client")) { Serial.println("Connected."); } else { delay(5000); } } }

void loop() { if (!client.connected()) { reconnect(); } client.loop();

// Read sensor data int rawValue = analogRead(sensorPin); float current = rawValue * sensorCalibration; // Adjust based on sensor

// Calculate power float power = voltageCalibration * current; // Simple power calculation (P=VI)

// Publish data to MQTT String powerStr = String(power); client.publish(topicPower, powerStr.c_str()); Serial.print("Power: "); Serial.println(power); delay(2000); // Send data every 2 seconds }

3. Upload Code

Connect your ESP32 to your computer.

Select the correct board and port in the Arduino IDE.

Upload the code to the ESP32.

Part 3: Setting Up Home Assistant and MQTT Broker

1. Set Up MQTT Broker

If you don’t have an MQTT broker, you can use Mosquitto on your local network or use an online MQTT service like HiveMQ.

Install Mosquitto on a Raspberry Pi or a computer running Home Assistant.

Configure Mosquitto by setting a username and password for secure access.

2. Configure Home Assistant

In Home Assistant, you’ll add the MQTT integration to receive data from the ESP32.

Go to Settings > Integrations and search for MQTT.

Enter your MQTT broker details and save the configuration.

3. Add a Sensor in Home Assistant

In your Home Assistant configuration file (configuration.yaml), add the following entry to display power data:sensor: - platform: mqtt name: "Home Power Consumption" state_topic: "home/energy_monitor/power" unit_of_measurement: "W" value_template: "{{ value | float }}"

Restart Home Assistant to apply changes.

You should now see a Home Power Consumption sensor in your Home Assistant dashboard.

Part 4: Testing and Using the Energy Monitor

Power on your ESP32 and ensure it’s connected to Wi-Fi.

Open Home Assistant, where you should see the real-time data of power consumption.

Monitor the data over time and optimize energy usage based on the data.

Conclusion

With this DIY Smart Home Energy Monitor, you can track power usage across various appliances in your home. This project introduces core IoT concepts such as data acquisition, MQTT communication, and integration with Home Assistant. You can further expand this setup by adding more sensors or even automating appliances based on usage patterns.

Vaporesso Eco Nano 2 Pod Vape Kit Review: A Better Choice than Disposable? 

Following the success of the Dojo Sphere X 40K Puff Disposable, Vaporesso introduced a revolutionary product to replace it: the Vaporesso Eco Nano 2 Pod Vape Kit, an upgraded device based on Eco Nano pod. This new release caters to vapers looking for a more sustainable, user-friendly, and powerful vaping experience. By swapping the disposable model for a reusable and refillable pod kit, Vaporesso takes a step toward both environmental responsibility and enhancing the user experience. This review delves into the detailed parameters of the Vaporesso Eco Nano 2, its standout user experience, and a comparison with its counterpart, the Eco Nano Pro. Let’s explore what makes the Eco Nano 2 an exciting option for both beginners and seasoned vapers. Vaporesso Eco Nano 2 Pod Vape Kit: Overview and Parameters The Vaporesso Eco Nano 2 Pod Vape Kit combines the convenience of a pod system with powerful, modern vaping technology. It is designed to be compact, efficient, and easy to use, while offering a smooth and consistent experience.

This advanced technology ensures a consistently rich and smooth vaping experience while prolonging pod life by delivering more puffs with every refill. What’s in the Box? - 1 Vaporesso Eco Nano 2 Battery (1000mAh) - 1 Vaporesso ECO Nano 0.6Ω Mesh Pod (Pre-installed) - 1 User Manual - 1 Warranty Card User Experience: Smooth, Long-Lasting, and Beginner-Friendly User experience is at the core of Vaporesso's design for the Eco Nano 2 Pod Vape Kit. Whether you’re transitioning from disposables or upgrading from an older pod system, the Eco Nano 2 impresses with its seamless operation, long battery life, and outstanding flavor production. Ease of Use The Eco Nano 2 is designed with new vapers in mind. It’s straightforward to use and maintain, making it an ideal choice for beginners. The bottom fill system for the 6ml pod is user-friendly, though some users may find it a bit tricky at first. Once filled, the pod clicks back into place securely, with no risk of leakage. The 1000mAh battery provides more than enough power for all-day vaping without constant recharging, and the USB-C fast charging port ensures that the device is ready to go in no time. A 4-level LED indicator gives a clear readout of the remaining battery, preventing any unwanted surprises during use. Flavor and Vapor Production Thanks to Vaporesso’s COREX technology, the Eco Nano 2 delivers a consistently smooth, rich flavor that competes with higher-end devices. Whether you're using nicotine salts or regular e-juice, the 0.6Ω mesh pod heats evenly, producing dense clouds and well-balanced flavor profiles. Vapers report that the Eco Nano 2 excels in replicating intense, flavorful draws, often surpassing their expectations, especially considering the device’s compact size. The airflow is smooth, and the mouth-to-lung (MTL) draw is perfectly calibrated, making it suitable for users looking for a cigarette-like feel.

The 1000mAh battery is optimized to support up to 18,000 puffs per pod, ensuring that users get maximum value out of each refill. This is significantly higher than most competitors, which helps reduce the frequency of pod replacements. Portability and Design The Eco Nano 2 is impressively lightweight and compact. Its dimensions make it pocket-friendly and highly portable for on-the-go vaping. The minimalistic design, combined with a sleek aluminum finish, gives it a premium feel without the weight or bulk of larger devices. Learning Curve for New Users Though the Eco Nano 2 is relatively easy to operate, first-time users may need to get accustomed to the bottom-fill mechanism and pod replacement. However, with the clear user manual and visual indicators, Vaporesso makes this process as intuitive as possible. Overall Experience In summary, the Vaporesso Eco Nano 2 Pod Vape Kit offers a smooth, flavorful, and convenient vaping experience, especially for those transitioning from disposables. Its powerful battery, eco-friendly design, and long-lasting pods make it a standout in its category.

Vaporesso Eco Nano Pro Pod System Key Features: - Price: $19.99 - Battery Capacity: 1000mAh, similar to the Eco Nano 2 - Pod Capacity: 6ml refillable pod - Operation Modes: ECO and Power modes for customizable vaping experiences - Adjustable Airflow: Customizable airflow control for a personalized draw - HD Screen: Displays battery life and firing mode - Puff Count: Up to 25,000 puffs with its new pod system Differences: - Power Modes: - Eco Nano Pro: Offers two modes—ECO for longer battery life and Power for more intense vapor production. This allows users to switch between a stronger or more energy-efficient vape. - Eco Nano 2: Lacks these power modes, delivering a consistent experience without the ability to tweak power settings. - Screen and Controls: - Eco Nano Pro: Comes with a HD screen and firing mode indicators, giving users more control over their vaping experience. - Eco Nano 2: Minimalist design without a screen, which simplifies use but may lack the precision that advanced vapers seek. - Adjustable Airflow: - Eco Nano Pro: Offers adjustable airflow, which allows users to fine-tune the draw according to their preference. - Eco Nano 2: Does not have airflow control, providing a consistent but less customizable draw. - Puff Capacity: - Eco Nano Pro: Promises up to 25,000 puffs per pod, outperforming the Eco Nano 2’s already impressive 18,000 puffs. - Pricing: - The Eco Nano Pro retails for $19.99, making it slightly more expensive than the Eco Nano 2, but the added features justify the price difference. Which One Should You Choose? If you’re a beginner or looking for an affordable, no-fuss pod system, the Eco Nano 2 is an excellent option. However, if you prefer more control, such as power modes and adjustable airflow, or if you need a higher puff count, the Eco Nano Pro is the better choice. Both devices are well-designed, durable, and user-friendly, but the Pro edges ahead in terms of customization and features. Final Thoughts and Verdict The Vaporesso Eco Nano 2 Pod Vape Kit is a stellar choice for anyone looking to transition from disposable vapes or those who want a portable, long-lasting pod system. It combines advanced technology with simplicity, making it suitable for new vapers while still offering a premium experience. The smooth draw, intense flavor, and impressive battery life make it one of the top contenders in the pod vape category. However, if you’re after more customization or plan to use your vape intensively, the Eco Nano Pro might be a better fit with its adjustable airflow and power modes. Both devices are excellent choices, but your decision should depend on how much control and power you want over your vaping experience. In conclusion, Vaporesso has once again delivered a high-quality, reliable, and versatile product with the Eco Nano series, ensuring that there’s something for everyone—whether you prefer simplicity or customization.

Arduino Due AT91SAM3X8E ARM Cortex-M3 Board

The Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. The Arduino Due AT91SAM3X8E ARM Cortex-M3 Board is the first Arduino board based on a 32-bit ARM core microcontroller. Arduino Due AT91SAM3X8E ARM Cortex-M3 Board has 54 digital input / output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button. The Arduino Due AT91SAM3X8E ARM Cortex-M3 Board contains everything needed to support the microcontroller; simply connect it to a computer with a micro-USB cable or power it with an AC-to-DC adapter or battery to get started. The Due is compatible with all Arduino shields that work at 3.3V and are compliant with the 1.0 Arduino pinout. The SAM3X has 512KB (2 blocks of 256KB) of flash memory for storing code. The bootloader is pre-burned in a factory from Atmel and is stored in a dedicated ROM memory. The available SRAM is 96KB in two contiguous banks of 64KB and 32KB. All the available memory (Flash, RAM, and ROM) can be accessed directly as a flat addressing space. It is possible to erase the Flash memory of the SAM3X with the onboard erase button. This will remove the currently loaded sketch from the MCU. To erase, press and hold the Erase button for a few seconds while the board is powered.

Arduino Due AT91SAM3X8E ARM Cortex-M3 Board pins:

Due follows the 1.0 pinout:

TWI: SDA and SCL pins that are near to the AREF pin.

The IOREF pin which allows an attached shield with the proper configuration to adapt to the voltage provided by the board. This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V.

An unconnected pin, reserved for future use Connections / Interfaces

Digital I / O pins :54

With PWM :12

USB :Yes

SPI :No

I²C :No

ICSP :Yes

TWI :2x

UART :4x

CAN :Yes

SAC :2x

LAN :No

Bluetooth :No

Note: Unlike other Arduino boards, the Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Providing higher voltages, like 5V to an I/O pin could damage the board.

Features:

A 32-bit core, that allows operations on 4 bytes wide data within a single CPU clock.

CPU clock at 84Mhz

96KBytes of SRAM

512KBytes of flash memory for code

A DMA controller, that can relieve the CPU from doing memory intensive tasks.
