3PM ET TODAY! Desk of Ladyada - RaaAWWwwwr PLEO battery repair 🦖🤖🔋

Part 2 of Desk of Ladyada! Last week, we tackled a battery issue with our old PLEO dinosaur robot by sourcing high-capacity NiMH packs from DigiKey. And, we'll look at the need for a specific 12V US AC/DC adapter with an 800mA output and a 3.5mm OD plug to replace the UK plug, ensuring the robot could be charged again!

Ladyada's Desk Gets a Lift! 🖥️⬆️ https://youtu.be/wzfQadPrK3Q

Ladyada's desk is getting an upgrade with a motorized sit-stand kit. Prototyping and testing of various boards are in progress. They are also looking for an I2S DAC with volume control and headphone amp, following the obsoletion of TLV320AIC23.

3pm ET today, LIVE!

Desk of Ladyada - Sniffly Sunday! & The Great Search - I2S microphone https://youtu.be/fuITok1UdRU

Recovering from a cold but still managed to work on new prototypes like the ICS43434 I2S microphone, TMF8828 ToF breakout, TCS34303 Color sensor, and AS7343 Spectrometer. Also prepped the RP2350 HSTX Feather for testing and upcoming stock release!

Desk of Ladyada - Final Revision Push, 600 and beyond 🛠️🔍🕒

Finishing a 16-month revision push for designs like CLUE and Feather Sense boards, popular for Bluetooth LE and sensors. Despite chip shortages, new prototypes are underway, including a Feather Sense TFT board. A search for LSM6DS33 replacements due to IMU shortages in 2021/2022 is ongoing, aiming to restock sensor-rich designs.

JOIN US AT 9PM ET! The Desk of Ladyada - ESP32-S3 RGB TFT Experimentation 🖥️💡🔋

We are testing ESP32-S3 TFT board prototypes. Used ESP32-S3 RGB TFT Eval with Arduino library. Trying out the OpenAI code interpreter. Using a new board with native GPIO & FPC connector. Redesigning for PSRAM's octal mode, current board displays MJPEGs! "The Great Search" Searching for replacement capacitors for old boards, especially tantalum, polymer or electrolytic. Identifying capacitance & voltage can be tricky.

[adafruit]

Ladyada discusses newly arrived 3.5" TFT capacitive touch screens & their ease of testing via EYESPI. She explores unique RGB TFT samples & an ESP32-S3 board's complexities. Additionally, she delves into DIP chip clips, handy tools for component probing, sparking a hunt on DigiKey.

TPA6130 is an I2C-controlled Stereo Headphone Amp 🎧🔊📻

While working on our rev B of the DS4420 mono audio amplifier with I2C control, we remembered that we also covered the TPA6130A2 (https://www.digikey.com/en/products/detail/texas-instruments/TPA6130A2RTJR/1531096) on a Great Search video twoish years ago (https://blog.adafruit.com/2022/08/30/the-great-search-stereo-headphone-amplifier-with-i2c-control-thegreatsearch-audio-digikey-digikey-adafruit/) this chip is a headphone amp that can drive 300mW into 16 ohm loads, from differential inputs. The gain can be configured over I2C, mute, and a few other minor configurations. We put a headphone jack on this board to be used instantly for audio projects! Coming soon.

Great Search part turns into an ultra-precision temp+RH sensor 🌡️🔍💧

A few weeks ago we were looking at the latest in temperature and humidity sensors on The Great Search (https://blog.adafruit.com/2024/03/04/the-great-search-high-accuracy-temperature-humidity-sensor-thegreatsearch-digikey-digikey-adafruit/) and we chanced across the HDC3020 series (https://www.digikey.com/en/products/detail/texas-instruments/HDC3020DEFR/17884961) of 'ultra accurate' humidity sensors, with 0.5% accuracy in most cases. this seems like a nice addition to our collection of environmental sensors so we spun out a quick QT sensor (https://www.adafruit.com/stemma) for plug-n-play usage. the HDC can use 2-5V power and logic so no level shifting required! and you can select up to 4 I2C addresses, using jumpers on the back.

EYE SPI with my little eyes, a new accessory for our QT Py

We have done 300 revisions https://blog.adafruit.com/2023/04/27/300 including just-about-all of our OLED, E-Ink and TFT displays to add EYE SPI connectors https://www.adafruit.com/search?q=eye+spi to make it very fast and easy to wire up displays, touchscreens and microSD cards without a ton of breadboarding. yay! but now we have to make the controller side easy as well. First up, this EYE SPI accessory for the QT Py uses a slim FPC connector https://blog.adafruit.com/2023/04/04/the-great-search-narrow-body-fpc-connector-with-18-pins-and-0-5mm-pitch-thegreatsearch-digikey-digikey-adafruit/ and makes plug-n-play connectivity to our 2.8" capacitive touch screen child's-play https://www.adafruit.com/product/2090 works a treat - we'll be getting this into the adafruit shop faster than you can blink.
