In this tutorial, I am going to show you guys how to design this "Transformers PCB Badge" and how to solder the components to it.

Christmas ball light -6*RGB LED, IR RX,TX, CH32V003F4U6, charger

In this tutorial I am going to create a chaser circuit that can drive 20 or more LEDs using 555 timer IC and CD4017 decade counter.

Christmas star built on 18 LED diodes.

Write to Z80 memory without any special feature on board or firmware

This is a twin delta loop antenna designed for the 1200MHz band for HAM radio practitioners. It can be used by soldering an SMA connector.

The T.I. TMS7000 line of micro controllers is an interesting architecture. These boards will provide a new platform to explore it.
