Bus Pirate Support / Another BusPirate V3.5 free PCB built

July 30, 2011, 08:08:48 pm

After I finished the SOIC version (viewtopic.php?f=4&t=2577), I continued with the SSOP one.
As before, everything recycled or free sourced, except fot the FTDI chip.

Bus Pirate Support / BusPirate V3.5 SOIC free PCB built

July 23, 2011, 07:36:57 pm

Finally I have completed my free Bus Pirate built, must say that this is my first attempt to solder a complete smd circuit.
It turned out to become almost completely free, all parts were recycled or free sourced (except for the FTDI).

3 hints in case your are missing some parts to complete yours:

-Found a lot of 4066s IC on old CD-ROM drives.
-Old motherboards are a great place to get resistor networks.
-That old cell phone wich died from drowning may donate the usb connector...

Project development, ideas, and suggestions / home made QFP50 dangerous proto board

June 11, 2011, 12:31:31 am

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!

General discussion / free USB IR Toy trough-hole

Yesterday my free PCB arrived.The envelope and PCB came in perfect conditions.

After a couple of minutes looking for parts, found most of them, except for the IR receivers.
I didn't had a narrow 28 DIP socket, so I took a wide one from an old network card and cutted the plastic bridge between both sides. A few other components are recycled, like the USB connector.

One hour later everything is soldered, time to write the bootloader.
I'm using my cheap pickit2 clone (this one was programmed with a serial PIC writer wich Ian published in DIY life some time ago).

Everything went OK, later firmware was written and tested in serial console.
Now I just need to find those IR receivers.
Thanks Ian!
