Atmel Microchip Studio 1 1/2 years ago now I have finally abandoned Microchip (Atmel) Studio for programming AVR microcontrollers. I have been using Atmel Studio from the very first day I have been programming AVR microcontrollers and I have been following it through the version 4 to 7. But already a couple of years […] Continue reading VSCode for everything  There are other, more detailed analyses, looking behind the curtains of ChatGPT, this is just a short summary of my own experiences. For more details, look e.g. here: ChatGPT: Interacting via a conversational way! ChatGPT is this (in)famous artificial intelligence which has been all over the media lately. It describes itself as a language […] Continue reading We need to talk about ChatGPT  The electronics distributor https://www.pollin.de/ is often selling surplus displays, but normally these are not very well documented. The TIAN MA A2C00096100 LCD module is a 90 mm x 20 mm character display with on-board chip-on-glass controller. It has 20 alphanumeric character positions, actually 18+2 since there is a vertical 1-pixel wide bar separating the […] Continue reading The TIAN MA A2C00096100 LCD  User cbm80amiga has uploaded a nice library to render 7-segment numbers on graphical displays – especially for Arduinos. But the code can as well be used without any Arduino in the proximity, just a slight change in the library made it an universal C++ object. It had the ambition to follow up with further […] Continue reading Nicely rendered 7-segment numbers  sagecell.makeSagecell({“inputLocation”: “.sage”}); Following a discussion on Facebook I put here an online tool to calculate the output of a voltage divider consisting of a fixed resistor and an NTC thermistor following a first order Steinhart–Hart equation. The calculations are based on a voltage divider where either the voltage over the NTC or over […] Continue reading Temperature measurements with an NTC thermistor  This page without a frame: https://sciencetronics.com/uwezi/avrbaudrate.php .errordiv { padding:10px; margin:10px; border: 1px solid #555555;color: #000000;background-color: #f8f8f8; width:500px; }#advanced_iframe {visibility:visible;opacity:1;vertical-align:top;}.ai-info-bottom-iframe { position: fixed; z-index: 10000; bottom:0; left: 0; margin: 0px; text-align: center; width: 100%; background-color: #ff9999; padding-left: 5px;padding-bottom: 5px; border-top: 1px solid #aaa } a.ai-bold {font-weight: bold;}#ai-layer-div-advanced_iframe p {height:100%;margin:0;padding:0}var ai_iframe_width_advanced_iframe = 0;var ai_iframe_height_advanced_iframe = 0;var aiIsIe8=false;var aiOnloadScrollTop=”true”;var aiShowDebug=false;  Some recent highlights from my home-made circuit boards using the toner-transfer method. 0.5 mm FPC breakout board Yes, I have been told that I am crazy before… Designed in KiCAD 0.5 mm pitch FPC breakout board – before etching 0.5 mm pitch FPC breakout board – half-way etched Continue reading Some Toner-Transfer PCB Highlights  In a recent quick-and-dirty project with a Wemos D1 mini clone I had some problems with the reliability of the code. The ESP8266 contains two watchdogs which have the sole purpose to reset the chip if the firmware ever should get stuck. Previously I experienced these watchdogs to be too aggressive, but this was […] Continue reading A tiny watchdog  I recently visited IKEA again and got interested in their affordable line of home automation/LED lighting products called TRÅDFRI (meaing wireless in a play-with-words kind of Swedish). Of course there was already an internet community active in hacking these devices and I joined in. Getting started I installed the gateway and after pairing devices […] Continue reading Hacking IKEA trådfri lighting automation  Exactly one month later – our electronics course at Uppsala University just approaches its end – and I got the next shipment for my new project: 1.1 km of equipment wire. |
