Quick And Easy DIY PIC Development Board

diy_pic_dev_board

A few months back, [Phil] was looking to get into PIC development, but he couldn’t seem to find a simple development board for the PIC16F883 microcontroller he wanted to use. Since no retail offering had exactly what he was looking for, he decided to put together a dev board of his own.

He spent a couple hours in Eagle, putting together a simple board layout. [Phil] then busted out the iron and copper clad, making his dev board a reality using the tried and true toner transfer method.

He says that the board itself is quite simple, consisting of little more than the PIC, an LM1117 linear voltage regulator, and all the pin headers you could possibly need. While very basic and not necessarily a hack, we do like seeing people make their own tools when the market doesn’t provide what they want.

If you have been looking around for a simple PIC development solution, be sure to swing by [Phil’s] site – all of the schematics and layout files are free for the taking.

Dev Board From An AVR Programmer

[jethomson] sent in a build he’s been working on that turns an inexpensive AVR programmer into a development board. The build is based on the very affordable USBasp programmer that’s based on an ATmega8. With hundreds of these boards available from China for less than a Hamilton, we’re wondering how soon it will be before we see these boards end up in other projects.

After fiddling with the AVR fuse settings, [jethomson] managed to burn some code to the microcontroller. After that, all that was required to upload software to the programmer is a bit of solder, a push button, and an external programmer. [jethomson] also managed to make this little AVR programmer compatible with the Arduino environment with a small addition to the boards.txt file.

[jethomson] included a few bits of software as an example – he ported the haunted USB cable and adapted the USB business card to print out, “All work and no play makes Jack a dull boy.” Nice work, and we can’t wait to see it in future projects.

An ARM Dev Board You Can Make At Home


[BarsMonster] just challenged our conceptions of ARM development with his single-sided development board that’s loaded with an STM32F100 (PDF warning) ARM microcontroller. The board is remarkably simple – just a regulator, resistor and a few caps are necessary to get a $1 ARM μC up and running.
