Nonlinearcircuits Numberwang Build Manual & Bom

This module is basically a 4:16 decoder with sync and async modes. In use, patch for signals to the 4 inputs and
generate an endless variety of gate patterns. If nothing is plugged into the sync input, then the circuit will change when
one of the 4 inputs is changed, with sync it will only change when the signal on sync is high.
The only tricky point in the build is choosing the resistors for the gate outputs and LEDs. These are marked 1k/2k2 on
the PCB, which are good values for low brightness LEDs. If using superbright LEDs and don't want to go blind,
replace the 1ks with 3k3 and replace the 2k2 with 6k8. This will keep the gate outputs to around 5V as well.
