Build Your Own
Z1FFER can be built on a breadboard. Above is how Z1FFER looked for many months before I had a PCB built. Here are the parts you need:
| Part No. | Description | Quantity | Supplier |
|---|---|---|---|
| SN74LS14N | Hex-Schmitt Trigger | 1 | mouser |
| CD4013BE | D-Flop | 1 | mouser |
| .22µf Cap | .22µf Cap - 1.5mm lead spacing | 2 | mouser |
| 0.1µf Cap | 0.1µf Cap - 2.5mm lead spacing | 1 | mouser |
| 1µF Cap | 1µF Cap - 2mm lead spacing | 2 | mouser |
| 10µf Cap | 2 | mouser | |
| MAX662A | 12V Switching regulator | 1 | mouser |
| 2N3904 | NPN Transistor | 3 | mouser |
| 4.7k resistors | 4.7k resistors | 1 | mouser |
| 1M resistors | 1M resistors | 1 | mouser |
| 10k resistors | 10k resistors | 2 | mouser |
