I’ve soldered my first SMD component today. No idea yet if it will work.
Finally finished my DIY keyboard the green push button toggles the play/pause function on the connected Mac. Feels good to be building something again (the image shows an Arduino Micro in a transparent plastic case connected to a push button. With a yellow “DIY” sticker on it).
Time to tinker with an Arduino. I am trying to create a custom media key keyboard.
I got a example board to try learning soldering SMD components.

I need to remember this for my next project. Not happy that it is cloud-based, but it looks more accessible than the open-source alternative I’ve tried.
I am sorting and ordering my electronic components.
Yesterday I found Logisim-evolution, a free digital circuit simulator. Just the tool I need for my CPU project. Now I’m in the progress of designing my circuit in it. Looks good so far. Found it via this youtube video: Intro to Logisim Evolution, the free and oh-so-good logic simulation software.
The first simulated “program” running on my own instruction set. It takes more time than expected but from here it’s mostly repetition to finish it.
Designing a CPU you can actually still build with discrete elements and has a useful set of capabilities is quite complex project. And a significant trade-off between features and complexity. Just adding one register more makes it much more complicated than I expected.
@V_ Has it something to do with Chinese astrology? Soldering SMC’s sounds a bit tricky, but if you have a great iron it might be less so?

@odd it did not come with instruction from the homepage I assumed it is some sort of zodiac sign selector. But I many bought it to have some components to solder. On the backside, it also has some random chips which are not connected at all :-)
