My galvawisp and usbwisp where too slow with bigger pics. Therefore I’ve build a new programmer. This time I have chosen for a PICkit 2. The design I based my programmer on can be found here: Link
I changed the icsp connector to a sub-d version because all my projects use this connector. And it can withstand more abuse then a pin header.
The hexfile can be found on the microchip site: Link
