Flashing LED Christmas Tree Kit

The perfect Christmas decoration for the electronic enthusiast.This kit is ideal for beginners and professionals alike. Build your own Christmas tree complete with red, yellow and green LEDs the are driven by a transistor flashing circuit. 

 

Can be powered via the micro-USB socket (USB cable not included!) or via batteries (battery holder not included).

 

LED Lighthouse Solder Practice Kit

This simple flashing LED circuit is great for learning how to solder or to polish up on your soldering skills. It uses a 555 timer in the astable configuration to flash the LEDs continuously. The rate of flashing can be changed by adjusting the variable trimmer potentiometer R2 (f ≈ 0.3Hz-30Hz). It can be powered by a 9V PP3 battery (not supplied).

The kit is supplied with Yellow LEDs by default but you can choose Red, Blue, Green or White LEDs from the drop-down list above.

Non-Contact Metal Detector Kit

Basic metal detector sensor module with buzzer and LED alarm. Will detect metal at a range of up to 60mm, including through soil, cothing, etc. Requires an input voltage of 3-5V DC, which can be supplied to the module via the 2 pin screw terminal (e.g. battery pack, USB, power supply). The sensitivity can be adjusted by the VR1 potentiometer.



 

Smart Line Tracking Car Kit

Simple line tracking robot car kit that is designed to introduce people of all ages to electronics and soldering.

The red LEDs (on the bottom) illuminate the surface in front of the car and the LDRs (light dependent resistors) pick up the reflection off the surface. The comparator (LM393) will then determine if the car is following the line and make the necessary adjustments. R1 and R2 potentiometers are used to adjust the sensitivity of the LDRs.

Requires 2 x AA batteries (not included). 

Tools required: soldering iron, side cutters, Philips screwdriver

SMD Component Solder Practice Kit

Surface-mount PCB including components; ideal for learning surface-mount soldering. When the components are soldered correctly, the LEDs should flash and alternate. This kit has the following SMD packages: 0402, 0603, 0805, 1206 and SOT-23. Requires 3-12V DC to operate the circuit.


 

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.
