Notes tagged ‘debugging’
Take a piece of wire, solder one end into a loop and the other one onto a header pin and you’ve got a very useful test point for breadboarding. A piece of shrink tubing shrunk only on one end nicely insulates connected probe hooks and an extra shrink tubing ring around the breadboard end keeps this cover from sliding off.
If you need to monitor a RS232 line (or something else running through a D-Sub connector), use one of these open-style connectors. Their pins fit into a female D-Sub connector and provide ample space to attach probes.
