7228Re: Cheap ($10) logic analyzer ready to be built
- Dec 7, 2010I have a USB PIC programmer I bought on eBay, they go for about $25 and have a ZIF socket to handle just about any PIC up to the 40 pin ones.I use it to program the PICs for the interface boards on my model railroad. I also have the PICKit 2 which came in the starter kit I bought to learn some of this programming for myself.
