In my projects I often use microcontrollers which can be reprogrammed via ISP (in-circuit programming). If there is enough space, I usually intergrate a 6-pin ISP header, so that I can easily reload new firmware if required. However, sometimes, space is at a premium, which means I'll have to do without an ISP header.
So the aim of this project was to generate a contact clip for in-circuit analyzing and programming of standard DIP ICs with 0.1" pin spacing, which allows me to reprogram microcontrollers and EEPROMs, and also debug my developments by analyzing the pin signals on the ICs directly.
The pin contacts are made from standard pin headers. The bridge in the clip tweezers provides a spring to firmly clamp the contacts to the IC. Small gaps between the pins allow each pin arm to move individually, so that the contact force is spread to all pins evenly. The lead wires are fed from the inner rear of the clip through three holes to the outer front of the clip whe
