To raise what-thread models can you purchase the layout(s) circuit Board, solder (thin wire 1-2 mm), spitakavor (LTI-120), some thread Chinese soldering station like Lucky (with Hairdryer), a coil of wire mgtf, fine tweezers, small pliers. Resistors/capacitors are sold in sets of almost all denominations, it is better to take in SMD version. The instruments multimeter — optional, an oscilloscope is desirable. And then to think that I want to collect and, consequently, to buy the rest of the details. You can try a thread microcontroller unsolder on the layout, connect its serial port to a PC, hang on the legs of the LEDs and try to manage all these. Then to complicate the scheme and continue to investigate.
