Back to mignon construction. These are three short lengths of copper wire inexpertly soldered to a three pin screw terminal. This was my second attempt. On the first attempt (shown to the right) I managed to melt the plastic case of the terminal block. A resistance test shows good conductance from the terminals to the wires. As I said on [the Mail Day thread this morning](https://lookmumnocomputer.discourse.group/t/mail-day-thread/101/1290), the idea is to create a tripod bearing the Eurorack power and solder all the electronics (point to point style) between the legs. The whole thing gets drenched in clear epoxy resin, with the terminal sticking out at the top, and any other connections coming through the surface either separately or via a header strip. The resin dries hard and protects the circuit. I call this general style of construction _mignon vitrine_ (literally, “showcase mignon”). This particular construction method is _vitrine tripode_ (“tripodal showcase”). It’s sitting in an ice cube tray to check that I can pour the resin correctly and achieve the necessary coverage. ![IMG_20200719_193644531](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/5/51e6e3319779360b954968b1a088ca1be9f06101.jpeg) And here it is from the side showing my tragically bad soldering. ![IMG_20200719_193702484_BURST002](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/3/307cc6887e574e7ca1edcfa9db2f792510369403.jpeg) --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/fast-prototyping/1349)._
