What is it?

The kit supplies components to build a transistor based logical NAND gate with an indicator LED. The NAND gate design is similar to that used in TTL circuits. The two input pin connects to the emitter of two steering transistors which feed an output transistor and LED indicator. The fan-out is good which enables the NAND gate to drive multiple other gates.

Combine multiple NAND gates to make, an XOR gate, flip-flop, half-adder, full-adder, logic tester, etc. Details of these experiments can be found in the manual.

Why did you make it?

I'm interested in retro computing using transistors.

What makes it special?

Unlike many transistor gate designs, this is similar to TTL based designs.

Specification:

Board Dimensions: 1 inch x 1.1 inches
Input voltage: 4.5 to 9 Vdc depending on the application
Maximum current draw: 5-10 mA
3mm (M3) screw holes at the corners
Pin connectors are spaced such that the board can be optionally plugged into a breadboard
