PIC dev board (with programmer)

This Pic developmentboard, which still needs a new name, is 'based' on a arduino.An arduino is a little board with a microcontroller on it (usualy 2, 1 for programming and 1 for for learning/developing/etc).Most pic development board need an external programmer,

An arduino is a little board with a microcontroller on it (usualy 2, 1 for programming and 1 for for learning/developing/etc).
Most pic development board need an external programmer,
that is why i chose to add a pickit 2 (with reduced functioning) to the board so that you not only can program the PIC on the development board but also external PIC's of EEPROMS from microchip.
How i will implement this is still unknow, probably using a 4-Dipswitch or some headers.
The chose of the PIC will depend on what has as most functions as possible and is easely placed on the board so that all the i/o's will be available using (fe)male headers.
Update 1: the pickit 2 clone has been tested and found to be working properly (on a breadboard that is), i'm waiting for a first test on print until the 'final' design of the programmer is there.
Update 2: changed some values and some wireing while testing the programmer, update of the shematic will come soon.

Both projects have been prepared in EAGLE cad.
I do have home etched PCB samples.
The Tiny was shaped to fit inseide a Sub D connector housing.
The other was a development toy for PIC16F877A but of cours can be used for PIC16F887 or 18F45K22 for example. The latter is my favourite today.

Some years ago we had a project to program (and debug) PIC devices (actually 16F877A) with a simple Interface to the parallel port of a PC.
But the schematic was really simple creating the Vpp via a switch capacitor DC Converter. If you are interested I would send you the schematic and an eagle file.

Hello Meerweten,
I cropped your schematic as it was way too big (10222 x 6629 pixels) to be displayed on the site. When you export images from Eagle please use the standard 150 DPI setting. If I remember correctly, only illustrations up to 2048 x 2048 pixels can be displayed online.
Regards,
Clemens

I think that omitting PI10 and 12 would be a mistake as MC seem to be putting quite alot of effort into these devices.
