Probably the hardest part of assembling our Binary Epoch Clock Kit is keeping the LEDs aligned and all pointing the same direction. So we designed this simple tool to help out with that process. Not only does it help keep all of the LEDs aligned, but it makes soldering them in much, much quicker.
Normally, per our instructions, you would solder the LEDs in four at a time. But with this, simply insert all of the LEDs and then fit the jig onto the front of the clock PCB. It will hold all of the LEDs in place and correctly aligned while the board is flipped over. No need to even bend the leads over, to hold them in place, before soldering!
If you have access to a 3D printer, you can grab the model file from Thingiverse and print your own.
