Homemade QFP50 dangerous proto board test CNC precision:
I’m using the QFP50 dangerous proto board as a reference design to test the precision of a proxxon mf-70 retrofitted micro CNC. I’m quite happy with the results!

I make a lot of breakout boards that I usually use in my hobby projects. Most are input/output devices but some are microcontroller breakout boards.

We released the 28 Pin AVR Development Board back in 2008 and since then it has gone through many iterations. This week we release version 1.6 which adds 4 improvements. These improvements were based on customer feedback and we are very grateful for the feedback. Please keep it coming.

For an electronics hobbyist, knowing how to do PCB design is a must. Building prototypes on breadboards or with wire-wrap just doesn’t cut it, once you reach a certain point. Then, a PCB board needs to be made specifically for your project. The previous tutorial Homemade PCB (Etching) showed you a quick, simple, dirty and easy way to make your own PCB. This tutorial will expand further and show you how to make a 2 layer (top and bottom) pcb.

This project is a mini board for use with AVR ATtiny2313. Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.

This project shows how to build a LED holiday tree using a custom made circuit board. The circuit board is made using a Dremel rotary tool and doesn’t require any etching chemicals. You use the Dremel tool to cut a copper into a tree shape and route the two separate PCB sections that will power the LEDs. The LEDs and resistors will be soldered at the surface of the board. The result is pretty nice. Check the construction PDF on the link below.
