In this post are discussed some of principals used while designing this board.
Size and form factor
The goal of making this board is not to have a smaller or the smallest PCB that runs on… 500 more words
The new prototype PCBs just arrived from OSHPark – great quality as usual.
I noticed that there are only few things that I may change before call it official: slightly move some components around so they fit better and become easier to solder; add one jumper for switch on/off the optional button cell battery on the bottom of the board; make some pads and holes larger; … and few other things. 44 more words
Recently saw some discussion online (I think hackaday.com) regarding the merits of an oscilloscope in the modern hacker’s lab.
As I was working on an DC motor control driver using Pulse Width Modulation (PWM), I was getting odd behavior from the circuit when approaching full power output. 33 more words
I have finally managed to finish the first version of the schematics and PCB‘s and to order the first 3 pieces. This work is based on some previous experiments and designs. 255 more words
