Flangelicious Construction Guide www.electricdruid.net Electric Druid Flangelicious Flanger Project (Using either 4KNOBFLANGE or MULTIFLANGE chips) Overview! Build Instructions! Populate the PCB! 1N4148 Diodes! Resistors! Cup of tea and soldering check! Power protection diode! IC sockets! Regulator! Transistor! Ceramic bypass capacitors!
“Done?” column on the far right. If you hold the PCB with the “flangelicious” and “electric druid” logos the right way up, you’ll see that the components are arranged in three rows. The top row is passive components. The centre row is for the ICs, with a few other components.
Flangelicious Construction Guide www.electricdruid.net • 10K resistor x 6 - two on the top row, four on the bottom row • 100K resistor x 9 - six on the top row, three on the bottom row • 47K resistor x 7 - four on the top row, three on the bottom row •...
There are two trimmers, the 100K Resonance trimmer (marked “100K Res”) and the 10K clock bleedthrough trimmer (marked “10K Bal”). The resonance trim is in the centre row, to the left of the op-amps. The clock balance trimmer is top-right, next to the electric druid logo. Second cup of tea and Power Test Have a break.
Flangelicious Construction Guide www.electricdruid.net Something is required to prevent the pots from shorting out the back of the PCB. Many things work; all the way from expensive pot dust covers, to a couple of pieces of insulation tape stuck on the back of the pots, to a piece of cardboard stuck between the board and the pots.
Flangelicious Construction Guide www.electricdruid.net Off-board wiring This is the same for all pedals, pretty much. There’s a power input, a stereo 1/4” jack which serves as the input and powers the pedal up when something is inserted, a mono 1/4” jack for the output, and either a DPDT stomp switch, or a 3PDT stompswitch if you want an LED to show you the on/off status of the effect.

Flangelicious Construction Guide www.electricdruid.net If you have an oscilloscope (or a friend who does!) you can put the ‘scope probe on the test point (marked “TP1” in the centre of the board) and adjust the trim for minimum clock bleedthrough. If you don’t have an oscilloscope, you can do the same with a multimeter on a AC voltage range -...

Ideas for potential upgrades or customizations Adding CV inputs Since the Electric Druid FLANGE chips operate using 0-5V control voltages like many other Druid chips, it is possible to add CV control of the Frequency, Depth, or Rate controls. Adding Expression pedal inputs It is also possible to use an expression pedal in place of the pots.
