Step 3Perfboard? Or try just winging it freehand...
We will be using a 100mA white LED with a 140-degree spread. Start by slipping the leads through a scrap piece of perfboard to keep it upright.
If you want to follow the perfboard assembly, do that now, then solder the leads to the finished board.
The circuit is simple enough that the whole thing can be assembled freehand, which I will show you here.
Start by flipping the case over and bend the shorter (-) lead of the LED flat against the plastic. Then push it INTO the plastic by holding a hot soldering iron against the end of the lead until it melts it. Now it's SOLID!
