The process is fairly simple - just "wipe" off the original resistor with the side of your soldering iron tip, dab some flux on the new resistor (603 size on my board) and hold it in place with a small object (toothpick or similar). Then touch the iron to one end of the resistor ...
Virtual breadboard layout If you are new to soldering or have no interest in learning I would definitely recommend this option. Simply place the components in the holes and make connections with 18 gauge solid copper wire. You should be able to pick a small breadboard for less than $7. Vari...
It looks interesting, but since it’s a closed platform, I don’t think that I could recommend it as a solution. If you do build an interface in it that might be useful for sugar printing (or a whole sugar printer), we’d certainly be interested to hear about it! — Windell ...
