Tesla Coil Kit with Audio Input

Amaze your friends with this cool musical tesla coil kit. When fully assembled, this module will act as a tesla coil which will play audio through the arcs when an audio source (e.g. phone, laptop) is connected to the audio input of the coil. It runs on 15-24V DC, either from batteries or a power supply (not included). 

 

Power Input: 12-24V DC, 2.1 x 5.5mm 
Audio Input: 3.5mm stereo socket (only the left channel is active)
PCB Dimensions: 80 x 38mm

Please note: Tesla coils produce very high voltages; do not touch this device when it is turned on! This device produces intense radio frequency interference which can affect any electronic devices near it (e.g. pacemakers). Lastly, the arcs produced by Tesla coils can ignite flammable objects; keep all flammable objects away from the Tesla coil.

RAT-in-a-CAN Distortion Effect Kit

A distortion unit based on the legendary Pro Co RAT pedal from 1978. 

  We decided to make a RAT clone to rival the original “Pro Co RAT” and the best way to do this is to use the original Op Amp that gives the RAT its unique sound, the LM308. As we have some original LM308 ICs from the 70’s in our stocks we figured we could do it and do it well. There is a small difference in the fact that the original Pro Co RAT used the LM308N (8 Pin Plastic package) and we had the LM308H (8 Pin Metal can). The 2 chips are identical in how they work and sound but they look different, we decided to celebrate this difference in our design and so the “RAT in a Can” was born. 

   Unlike other modern clones that use “similar” Op Amps that can often sound a bit muddy and bass heavy, the RAT in a Can will give you gut-wrenching harsh fuzz and an astronomically high gain, this pedal is sure to make your guitar scream like a pack of angry rats.

  We hope you have as much fun building and using the RAT in a Can as we did designing and naming it.

Included in the kit
