If you're using copper tape to connect everything together, we'd suggest using several layers - apply one layer to the areas marked on the circuit first, stick your Blinky down with some more smaller bits of tape and then sandwich in the rest of your components with another layer, pressing the tape down well at every step. The components and the pads on the SDB will all need to make good contact with the copper to work properly!\u003c\/p\u003e\n\u003ch2\u003eReprogramming the Super Dinky Blinky\u003c\/h2\u003e\n\u003cp\u003eIf you're more interested in tinkering with experimental microcontroller firmware than making adorable papercraft ghosts, the N76E003 can be reprogrammed with an In-Circuit Programmer.
