I am trying to build aPIC 16f628a programmer.Any Ideas ?

I am trying to find the schematic for building a 16f628a programmer. Need help.

There are lots on the net. Here's an example of one that uses the parallel port.

Google for more.

Thanks for the quick reply, do you happen to know any serial ones ?

If you want a serial one I would suggest the InchWorm, mentioned in this forum - otherwise you're looking at JDM type programmers, but they have reliability issues.

And for just a bit more then the cost of an inchworm you can build the much faster USBed JuneBug.

Both the inchworm and the JuneBug need a programmed PIC. So unless you buy a kit you need to borrow or build a programmer to program the programmer. Both are very good.

I use a PICkit 2 USB with my iMac (using pk2cmd in a bash shell). I wired a little board that redirects the programming wires to the right places on the 16f628a. I compile with gpasm. It's fun to develop on the mac!
