3 assembly hints 1. Assembly (skipping this can lead to troubles ! ) ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 make sure you have the right tools: a good quality soldering iron (25-40w) with a small tip. Wipe it often on a wet ...

4 assembly hints 1.3 soldering hints : 1- mount the component against the pcb surface and carefully solder the leads 2- make sure the solderjoints are cone-shaped and shiny 3- trim excess leads as close as possible to the solder joint remove them from the tape one at a time ! Do not blindly follow t...

8 connect the led between the points ld1 and the earth (-). Connect the + and - of the battery direct to the + and - connections of the circuit. Remark: switching the + and - connections by mistake will only cause ic1 to be destroyed, because the rest of the circuit is protected by d7. Turn both tri...
