Controlling LEGO robotics with microcontrollers part 2. No hardware changes this time, only software. I make the software into a library and implement sensor auto polling using an Arduino hardware timer interrupt along with touch sensor debouncing.

I finally got around to doing some projects again. Tried interfacing LEGO Mindstorms NXT sensors with an Arduino Nano microcontroller. I started with the simplest sensor, the NXT touch sensor. The next post will be on the other NXT basic sensors.

I uploaded the model of the 3D printable front suspension strut replacement for the Nikko RC car to printables in case it is useful for anyone else. Will upload it to printables as well

Having a #3dprinter and some basic construction skills means it is easy to repair stuff instead of it going in the trash.
One of the front suspension struts on one of my step son's RC cars broke, and using Fusion I was able to design a replacement and print it on my @bambulabglobal.bsky.social A1
Being interested in 3D printers, my youtube feed was filled with videos about the new @bambulabglobal.bsky.social H2D today.
The one I clicked on as soon as I got the notification was this one from Clough42, one of my favourite engineering channels. As always, great review from James.
I made a short video about the reset circuit for my 8-bit breadboard computer:

Some more progress on my electronics project, to build a 8 bit breadboard computer from scratch using discrete chips:
Reset synchronizer circuit to hold reset active for 4 clock cycles and synchronize reset release with clock, made with four D-type flip flops.
A solderless breadboard with two integrated circuits and several passive components implementing a clock module for a 8 bit computer from scratch build.
First part of my breadboard computer build done, a clock module without any 555 timers, which is usually used for these Ben Eater inspire build.

Single stepping done. Used a schmitt triggered NAND gate instead of an inverter to lower the final chip count of the clock circuit, as I need NAND gates for other parts of the clock circuit

First baby steps towards my Ben Eater inspired breadboard computer, my first real electronics project.
Working on switch debouncing for clock single stepping. Next step is adding a schmitt triggered inverter to get a nice square transition.
Now that we have gotten a new 3D printer I can use the old Flashforge Adventurer 3 for tinkering. I made a tool for installing a SSH server on it.

After having wanted to build a breadboard computer in the style of #beneater for years, I am finally starting. I even made a web page to document this and other projects. I posted an short overview of the project at vegardmakes.com/electronics/...
