 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 […]

 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 […]

 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 […]

I just recently started with Canvas because Uppsala University has decided to use it as its upcoming LMS platform after a failed attempt with another product. Therefore I had already spent some time with Blackboard and was quite fond of the calculated questions type in quizzes. I quickly found out that Canvas offers […]

 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 […]
