A lot of people really liked seeing the outside of the Philips Intellivue MP5, so let’s take a look on the inside

When you take off the back housing this is what you’re greeted with. We can see the power supply, the rear IO board, and the measurement module

After removing a few more T-10 screws the power supply and the rear IO board slide right out. This is the rear IO board

1: USB port

2: Nurse call relay output

3: RJ45 Ethernet Jack

4: VGA video out

5: board to board interconnect for the power supply

6: Nurse call Relay, the actual Relay component

7: Battery contacts

8: An RJ45 Jack not accessible from the outside, if I had to guess this is either a management port, or it’s a backup port in case the one accessible from the outside breaks but qualified technicians still need Ethernet access to perform maintenance.

9: Piezoelectric buzzer, this will beep is the power supply suddenly gets disconnected and it will continue to beep for quite a while after the power supply is disconnected and even if there’s no battery on board

10: 2 super capacitors. Super capacitors have specs that are somewhere in between a battery and a capacitor. The larger one is rated at 2.2 farad and the smaller one is rated at 1 farad. Farad is the unit of measure for capacitance and it’s named after Michael Faraday. If I had to guess these serve 2 purposes. 1 is to make the power loss buzzer beep and the other is to keep the date and time and any configuration settings stored in volatile memory since there’s no CMOS battery. This is actually pretty smart because batteries die and often leak, but super capacitors don’t leak and corrode and they are ridiculously fast at charging up.

After removing the power supply, recorder driver board, and rear IO board this is what we are left with. The motherboard, the measurement module, the NBP pneumatic pump, and the LCD high voltage backlight board. It uses a fluorescent backlight so it needs a high voltage to make it light up, this can be anywhere from 500 to 1200 volts but they often provide very little current so touching it probably kill you but I still wouldn’t recommend it.

After removing the measurement module were left with just the backlight driver board, the motherboard, and the NBP pneumatic pump. There is a metal shield over the main components of the motherboard for EMI shielding.

Removing the metal shield grants us access to the CPU (the largest chip on the board) what I assume is a graphics driver chip (the second largest square chip) and 2 EPROMs that are the memory for some software aspects.

Once everything is out we can get a look at everything

1: Battery

2: measurement module side plate

3: measurement module

4: printer

5: Rear IO board

6: printer driver board

7: power supply

8: everything else

The attention to detail is amazing! That one little hole in the plastic just exists to access that screw inside. You can certainly tell that this device was never meant to be a consumer device. It’s built to be taken apart and serviced. All the screws are identical which makes disassembly and reassembly very easy. Unlike consumer products you can definitely tell that there was no expense spared in this things hardware design, that’s due to the fact that they know hospitals are going to pay the 5 figure price of the device because of its extreme quality, attention to detail and very long projected life cycle. Unlike consumer electronics it’s made in Germany and has a ton of hand assembly involved.

This is everything I have for mine. The monitor itself. 3 lead ECG cable. 5 lead ECG cable. Pulse oximeter. Hospital grade IEC power cable. Blood pressure hose. Adult arm blood pressure cuff. And the Intellivue remote. I got the remote today, idk why but people are selling them for super cheap on eBay. I paid $10 for it brand new in box. They usually go for like $500 from philips directly so I have no idea why people are selling them for so cheap. It does have to be plugged in via USB but it comes with a very long cable.

I finally got around to getting one of my servers to run the Intellivue XDS application. It’s a windows application meant to act as the server for Intellivue monitors. It also has a remote monitor function so you can view what’s on the monitor on the server, but it doesn’t work with the software version my monitor has. It can also log data but I spent 4 hours trying to setup the windows server needed to get that to work and just couldn’t get it to work. It’s probably due to the fact that the documentation on it is absolutely terrible.

hey flans, what's that pedal you've started using on Minimum Wage, that makes like a door buzzer sound? that thing is INTENSE

It's actually the old Line 6 FM4 (it's the big old-style pedal-this is the purple one) It has modulation effects and synth/filter effects. It actually has a very warm MuTron-like auto-wah (a lesser loved sound except for Deadheads) that I am currently using on Particle Man. (Kinda subtle) But it can also do some EXTREME fuzz-filtering. Years back I played Older on it and it was pretty nuts-it was a favorite sound for me.

But it had so much dust and filth coffee and water poured into it, and half the plastic parts had broken off so I couldn't adjust it or use the batteries since the lid fell off-it just was trashed. I just took it off my board to clean it up and then never got back to it. Finally over covid got another new-old-stock one and started setting it up. Takes a while to dial in because it's very volume sensitive (and I play much harder in front of people than when there aren't people-and that fact took me a couple of decades to figure out!)

They have updated that line recently (! damn-bad timing) and it's smaller but seems to have all the crazy sounds... I moved too soon!

Esplora Arduino game controller

The ESPLORA Arduino game controller Board is an Arduino-compatible microcontroller board based on the Arduino Leonardo. Unlike previous models, it comes equipped with a variety of built-in sensors for immediate use in interactions.

This guide is perfect for individuals interested in using Arduino, but who don’t want to dive into electronics right away. To learn how to use the ESPLORA Arduino game controller Board in a simple and clear manner, be sure to read the Getting Started with Esplora guide.

The ESPLORA Arduino game controller Board boasts onboard sound and light outputs, as well as multiple input sensors such as a joystick, slider, temperature sensor, accelerometer, microphone, and light sensor. Additionally, it offers the option to enhance its functions through two Tinker-kit input and output connectors and a socket for a color TFT LCD screen.

Similar to the Leonardo board, the ESPLORA Arduino game controller Board also utilizes an Atmega32U4 AVR microcontroller with a 16 MHz crystal oscillator. It features a micro USB connection that can function as a USB client device, such as a mouse or keyboard. Additionally, there is a reset push button located in the upper left corner of the board for restarting purposes.

There exist four indicators, each displaying a different status.

The green indicator shows if the board is currently being powered.

The L [yellow] connects directly to pin 13 on the micro-controller for easy accessibility.

The [yellow] LED indicates data being transmitted or received through the USB connection.

Within the board lies all the necessary components to support the microcontroller. To begin, just connect it to a computer using a USB cable. The ESPLORA Arduino game controller Board is also equipped with built-in USB communication, allowing it to function as a mouse or keyboard when connected to a computer. It also offers a virtual serial/COM port (CDC). This alters the behavior of the board, which is further explained on our getting started page. On this page, you can find all the instructions for configuring your board and utilizing the Arduino Software (IDE) for coding and electronics experimentation.

The transfer of data, both in and out.

The ESPLORA Arduino game controller Board features a classic gamepad design, including an analog joystick on the left and four push buttons on the right. It also comes equipped with several onboard inputs and outputs:

The analog joystick features a center push-button and two axes, designated as X and Y. There is also a central pushbutton for added functionality.

Arranged in a diamond formation are 4 push-buttons.

The slider for the linear potentiometer is located towards the bottom of the board.

A tool to capture the volume (amplitude) of the surrounding environment.

A sensor that detects light to measure brightness.

The temperature sensor measures the surrounding temperature.

A three-axis accelerometer detects the orientation of the board with respect to gravity, along the X, Y, and Z axes.

The buzzer has the ability to generate square-wave tones.

The RGB LED features Red, Green, and Blue elements that allow for color mixing and a bright display.

The TinkerKit Inputs allow for easy connection between the sensor modules and 3-pin connectors.

The TinkerKit Outputs allow for easy connection of the TinkerKit actuator modules via the 3-pin connectors.

The TFT display connector can be used for a color LCD screen, SD card, or any other devices utilizing the SPI protocol.

To fully utilize all available sensors, the board employs an analog multiplexer. This way, multiple input channels (excluding the 3-axis accelerometer) can share a single analog input of the microcontroller. Selecting which channel to read is done through four additional pins on the microcontroller.

Communication is essential in any relationship, whether it be personal or professional. It plays a crucial role in maintaining strong connections and fostering understanding between individuals. Effective communication allows for open and honest dialogue, facilitating problem-solving and building trust. Without good communication, misunderstandings can occur, leading to conflicts and strained relationships. Therefore, it is important to prioritize effective communication in every aspect of our lives.

The ESPLORA Arduino game controller Board for the Leonardo offers various features for connecting with a computer, another Arduino, or different micro-controllers. The ATmega32U4 enables serial (CDC) communication through USB and is recognized as a virtual com port on the computer. It also functions as a full speed USB 2.0 device and can be used with standard USB COM drivers. A .inf file is needed for Windows.

The Arduino software comes equipped with a serial monitor for easy transmission of text data to and from the board. Whenever data is being sent via the USB connection to the computer, the RX and TX LEDs will light up on the board. Additionally, the ATmega32U4 has SPI capability accessible through the SPI library. In addition, the Esplora can act as a standard keyboard and mouse, allowing you to use programming to manage these input devices via the Keyboard and Mouse libraries.

The act of creating computer software, also known as programming, involves writing code using various languages and tools. This process requires a combination of problem-solving skills, critical thinking and creativity. Programmers must constantly learn new techniques and adapt to ever-changing technology in order to produce high-quality programs.

To start using the Esplora with your Arduino software (download), simply choose “Esplora” from the Tools > Board menu. For more information, refer to the getting started page. The ATmega32U4 on the Esplora comes pre-loaded with a boot-loader, enabling you to upload new code without an external hardware programmer.

The AVR109 protocol is the chosen method of communication. To avoid using the bootloader, you can program the microcontroller through the ICSP header. Additional instructions are available for reference.

A dedicated library for the Esplora simplifies writing sketches, with methods available for reading sensors and controlling onboard outputs. These high-level methods also perform pre-processing of data, such as converting temperature readings to degrees Fahrenheit or Celsius. Additionally, the library allows easy access to outputs like the RGB LED. For further information and examples, please refer to the Esplora library reference page.

The automatic reset and bootloader activation are key components in the software’s functioning.

Rather than relying on the physical reset button, the Esplora utilizes a software-based reset triggered by opening and then closing the virtual serial/COM port (CDC) at 1200 baud. This initiates a processor reset, temporarily cutting off the USB connection to the computer and causing the virtual port to disappear. The boot-loader remains active for approximately 8 seconds before it can also be activated by pressing the reset button on the Esplora.

Please be aware that upon initial power up, the board will launch the user sketch instead of the boot-loader, if available. Due to the specific reset process of the Esplora, it is most effective to allow the Arduino software to attempt a reset before uploading, especially if you typically press the reset button before uploading on other boards. However, in the event that the software is unable to reset the board, you can manually initiate the boot-loader by pressing the reset button on the board.

The USB port is equipped with overcurrent protection to prevent any potential damage.

The ESPLORA Arduino game controller Board comes equipped with a re-settable poly-fuse to safeguard your computer’s USB ports against shorts and over-current. While most computers have built-in protection, the fuse adds an additional level of security. In the case of a short or overload exceeding 500 mA, the fuse will disconnect the connection until the issue is resolved.

Regarding the appearance of this object, its external features will be discussed.

The ESPLORA Arduino game controller Board PCB has a maximum size of 6.5 inches in length and 2.4 inches in width. The USB and TinkerKit connectors extend beyond the width dimension. Additionally, there are four screw holes that allow for attachment to a surface or case.

Regentropfen-Jagd: Ein einfaches Arduino-Spiel

Wie du das kleine Spiel "Fange den Regentropfen" am Arduino UNO R4 WiFi programmierst, zeige ich dir hier in diesem neuen Beitrag. Die Idee zu dem Spiel kommt von einem Makerspace, welche dieses für den Calliope Mini umgesetzt haben. https://youtu.be/2SOcPtQ0PkY Um das Spiel aufzubauen, brauchst du neben dem Arduino UNO R4 WiFi noch zwei Taster. Falls du das Arduino Plug and Make Kit besitzt, kannst du das Spiel auch damit umsetzen. Ich werde dir beide Optionen vorstellen, damit du das Projekt unabhängig davon, ob du das Kit hast oder nicht, nachbauen kannst.

Benötigte Ressourcen für dieses Projekt

Das kleine Projekt am Arduino benötigt nicht viele Bauteile: - einen Arduino UNO R4 WiFi, - ein USB-Typ-C Datenkabel, - ein Modulino Buttonshield, - ein Modulino Buzzer, - ein Qwiic Kabel

Bauteile - "Fang den Regentropfen" am Arduino Plug and Make Kit

Alternativ kannst du das kleine Spiel auch mit zwei Taster aufbauen und programmieren, dann benötigst du: - zwei Taster*, - zwei 10 kOhm Widerstände*, - ein Piezo Buzzer*, - diverse Breadboardkabel*, - ein 400 Pin Breadboard* Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links.

Aufbau der kleinen Schaltung mit dem Arduino Plug and Make Kit

Der leichteste Weg, das Spiel aufzubauen, gelingt mit dem Arduino Plug and Make Kit, da es bereits alle benötigten Komponenten enthält. Zwar ist das Kit nicht ganz billig, aber es bietet die Möglichkeit, viele weitere Projekte und Spiele zu realisieren. Aus meiner Sicht lohnt sich die Investition daher definitiv. Für dieses kleine Spiel müssen wir lediglich das Button Modulino Shield mit einem Qwiic Kabel mit dem Mikrocontroller verbinden. Mit den Schrauben wird das kleine Modul auf der Modulino Base geschraubt und somit sind wir auch schon fertig mit dem Aufbau.

Das Qwiic Kabel hat eine bestimmte Form, sodass dieses nur in eine bestimmte Richtung in die Buchse gesteckt werden kann, sollte es also etwas schwierig gehen, so prüfe dieses zunächst.

Programmieren des Spieles in der Arduino IDE

Für das Programmieren des Spieles verwende ich wie in den Beiträgen zuvor die Arduino IDE. Hier musst du so weit noch nicht geschehen, den Boardtreiber für den UNO R4 und die Bibliothek für die Modulinos installieren.

Für die LED Matrix benötigen wir noch zusätzlich eine Bibliothek, welche ebenso über den Bibliotheksverwalter samt Abhängigkeiten installieren. Das kleine, fertige Spiel kannst du dir nachfolgend als ZIP-Datei herunterladen.

Alternativer Aufbau & Programmierung mit Taster am Arduino

Wenn du das Arduino Plug and Make Kit nicht hast, aber trotzdem das kleine Spiel nachbauen möchtest, dann zeige ich dir hier nun den Aufbau und die Programmierung mit einfachen Komponenten. Aufbau der Schaltung Die Schaltung am Arduino UNO R4 WiFi ist mit den beiden Tastern auch recht schnell erledigt. Du kannst diese entweder mit einem PullUp oder PullDown Widerstand anschließen, oder du lässt diesen ganz weg und schaltest den Taster via Code über den internen 10kOhm Widerstand von der MCU.

Schaltung - Arduino mit Taster & Buzzer Der Piezo Buzzer muss an einen PWM Pin des Arduinos angeschlossen werden, diese sind am Board mit einer kleinen Welle / Tilde gekennzeichnet. Prüfen der Schaltung mit einem kleinen Programm Bevor wir in die Programmierung einsteigen, sollten wir prüfen, ob die Schaltung funktioniert und wir die Signale der Taster erfolgreich auswerten können. Dazu schreiben wir ein kleines Programm, welches die Status der Taster prüft und wenn einer betätigt ist, dieses auf der seriellen Schnittstelle ausgibt. //Taster Links am digitalen Pin D3 angeschlossen #define buttonLeft 3 //Taster Rechts am digitalen Pin D2 angeschlossen #define buttonRight 2 //Buzzer am digitalen PWM Pin D5 angeschlossen #define buzzer 5 void setup() { //beginn der seriellen Kommunikation mit 9600 baud Serial.begin(9600); //definieren das die Pins der Taster als Eingang dienen pinMode(buttonLeft, INPUT); pinMode(buttonRight, INPUT); //definieren das der Pin des Buzzers als Ausgang dient pinMode(buzzer, OUTPUT); } void loop() { //Wenn einer der Taster betätigt wird, dann //ist das Signal am digitalen Pin auf HIGH. //Wenn der Linke Taster betätigt wird, dann... if (digitalRead(buttonLeft) == HIGH) { Serial.println("Taster Links betätigt!"); //ausgeben eines hellen Tones für 100ms. tone(buzzer, 600, 100); } else if (digitalRead(buttonRight) == HIGH) { //Wenn der Rechte Taster betätigt wird, dann... Serial.println("Taster Rechts betätigt!"); //ausgeben eines tiefen Tones für 100ms. tone(buzzer, 300, 100); } } Im seriellen Monitor der Arduino IDE siehst du, dass mehrere Signale verarbeitet werden, obwohl wir nur einmal auf den Taster gedrückt haben, dieses nennt man prellen und kann recht einfach unterbunden werden. Wie man einen Taster am Arduino entprellt habe ich dir im Beitrag Arduino Lektion 87: Taster entprellen ausführlich erläutert. Programmieren in der Arduino IDE Für die Programmierung in der Arduino IDE benötigen wir neben dem Boardtreiber für den UNO R4 WiFi und Bibliothek für die LED Matrix noch Bounce2. Über Bounce2 können wir recht einfach die verbundenen Taster entprellen.

Hmm...well something's clearly gone wrong, but I can't work out what

Warning: Volume

I disabled all the software's modules, run the program and the buzzer still screams at me. Thinking I might have some power issue? But haven't been able to spot any shorts or anything

Rust Compiler Performance Triage

A rather rough week for compiler performance with regressions outweighing improvements by a considerable margin, in particular in real world crates. To add insult to injury, the biggest regressions came in rollups which make it difficult to trace the cause.

Triage done by @rylev. Revision range: b3f4c311..8bd12e8

Summary:

mean max count Regressions 😿 (primary) 1.5% 4.0% 176 Regressions 😿 (secondary) 1.8% 6.4% 147 Improvements 🎉 (primary) N/A N/A 0 Improvements 🎉 (secondary) -1.6% -4.1% 9 All 😿🎉 (primary) 1.5% 4.0% 176

7 Regressions, 5 Improvements, 3 Mixed; 4 of them in rollups 48 artifact comparisons made in total

Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

Quote of the Week

The long compile times where all responsibility is taken away from you is infinitely more effective than submission patterns in BDSM, where the graceful rustc takes over and all you have to do is wait until they tell you that you're a good person and that everything is alright!

Ganymed Entwickler Board

Einfach aber komfortabel und preiswert soll es sein. Und es soll bspw Schülern heflen elektronische Projekte zu realisieren.

Programmieren lernen und gleich ein paar tolle Projekte umsetzen. Aber keine offene und wilde Verkabelung, denn das ist in der Regel ja übliche Praxis. Das war die Idee hinter dem Ganymed Dev Board. Ein guter Ansatz um selbst mal ein eigenes Board zu entwickeln und es fertigen zu lassen. Keine Großserie, sondern maxiaml kleine Stückzahlen. Und am 14. Januar 2023 war der erste Prototyp fertig.

Der Projektname Ganymed war schnell gefunden, das Layout designed und die Produktion der Prototypen angeschoben. Das neuen "Ganymed Dev Board" ist erstmal "nur" ein Erweiterungsboard und damit wird es einfacher und komfortabler seinen Versuchsaufbau sauber einzurichten. Flexibilität und eine bessere Sicherheit durch weniger Verkabelung zu den wichtigsten Bauteilen. Speziell ausgelegt für den Raspberry Pi Pico oder Pico W. Die Microcontroller der Raspberry Pi Foundation UK eignen sich hervorragend für diese Aufgabe. Tolle Möglichkeiten zum kleinen Preis.

Die Leiterplatine erlaubt die Bestückung von beispielsweise einem BME280 Sensor und LED's, sowie einem Buzzer und einem SG90 Servo. Das ermöglicht schon die ersten wichtigen Projekte umzusetzen. Weitere Pin-Outs stehen zudem frei zur Verfügung. Das Ganymed Dev Board ist aber nur die erste Erweiterungsplatine mit einem ganz speziellen Layout. Weitere sind derzeit in Planung und es können ggf. auch die individuellen Wünsche eines Lehrers berücksichtigt werden.

Derzeit gibt es erstmal ein paar Prototypen. Die sind dann vorbestückt mit Steckleisten für die Aufnahme eines Raspberry Pi Pico oder Pico W. Auch zwei LED sind bereits montiert (optional mit und ohne Wiederstände). Andere Bauteile können über die vormontierten Pins gesteckt werden. Bei den LED ist die Bestückung mit Wiederständen für eine längere Lebenszeit der LED zu empfehlen. Durch die Steckleisten für den Microcontroller kann flexibel entschieden werden ob ein Pico oder ein Pico W verwendet werden soll. Die Microcontroller können so jeder Zeit ausgetauscht werden.

Der Servo selbst und auch das "Wetterstations Modul" (Sensor BME280) und der Buzzer werden wohl zunächst nicht vormontiert sein. Auf Wunsch wäre aber auch das kein Problem oder um auch hier auf Kabel zu verzichten kann an Stelle von einer PIN Leiste auch eine Steckleiste vormontiert werden. Letztlich ist die Frage, ob die Lötarbeiten Teil des Schulprojektes sein sollen. Dies schlägt sich entsprechend dann auch im Preis nieder.

Der Demo-Code auf Basis von Micropython ist zwar bereits verfügbar (https://github.com/techcree/ganymed.git), wird sich aber ggf. noch anpassen oder ergänzen. Auch sind etwaig norwendige Bibliotheken ggf. noch zu installieren, wobei die IDE Thonny für die Programmierung zu empfehlen ist. Diese ist für Chromebooks unter Linux und andere Betriebssysteme geeignet. Auch die passende .ufw Datei muss natürlich noch installiert werden. Später soll alles was an Software nötig ist auf Wunsch auch auf dem Pico bereits vorinstalliert sein.

Dieses Erweiterungs-Board soll für Bildungseinrichtungen bezahlbar sein und wird voraussichtlich ab ca. 3-5 Euro kosten. Ohne Bestückung von elektronischen Bauteilen und natürlich auch ohne Raspberry Pi Pico oder Pico W. Komplett ist wohl je nach Stückzahl mit ca. 20 Euro zu rechnen. Andere Layouts wie im nachstehend Bild zu sehen sind grundsätzlich kein Problem. Das Ganymed wurde in mehreren Varianten, als sogenannte Erweiterungsplatine designed. Das Layout ist abhängig von der später gewünschten Verwendung.

Das Ganymed Dev Board ist das erste Projekt dieser Art aus der Feder von STSKANTA.de. Sicher aber nicht das Letzte. Es ist wohl der Beginn einer "erweiterten" Leidenschaft für den Raspberry Pi Pico.
