[K.C. Lee] is busy working on his entry to The Hackaday Prize, and right now he’s dealing with a lot of assembly. For his entry, that means tiny SMD parts, and the vacuum pen he ordered from DealExtreme hasn’t come in yet. The solution? The same as anyone else who has found themselves in this situation: getting an air pump for an aquarium.
For this quick build until the right tool has time to arrive from China, [K.C.] took an old fish pump and modified it for suction. He doesn’t go over the exact modification to the pump, but this can be as easy as drilling a hole and stuffing some silicone tubing in there.
The ‘tool’ for this vacuum pen is a plastic disposable 0.5mm mechanical pencil. [K,C.] found this worked alright on smaller parts down to 0402 packages, but heavy parts with smooth surfaces – chips, for example – are too much for the mechanical pencil and aquarium pump to handle.
