The #1 product on my Tindie store in the Brymen 867/869 interface cable. The first version was based on an ATtiny45, but I then switched…
During the design phase of one of my recent projects, I had to pick a radio IC for transmitting data. One of the options which…
One very important aspect of any development is versioning. Sure, for small projects it might not be necessary, but I’ve gotten used to using Git…
For programming my STM32s, I’ve been using almost solely those 3-dollar USB dongles from China, which are basically ST-LINK/V2 clones. They do their basic task…
Some time ago, I experimented with FDM-printed stencils for solder paste dispensing. The result worked relatively well, but I was hitting the limits (mostly resolution)…
For less complicated projects, the foreground-background architecture (ie. main loop supported by interrupts) is perfectly fine. But at some level of complexity it is much…
As part of theoretical research for a possible future project I wanted to measure the efficiency, noise and also max output current of an MT3608-based…
I recently needed to send new firmware for one of my products to a customer. While he had the neccessary USB-UART converter, he didn’t have…
I’ve been developing for STM32’s for a couple of years now, and I did a lot of different projects – from large powersupplies to small…
If you are into electronics, you’ve probably built a clock at some point in time – it’s a daily use thing everyone finds handy, building…
