The Protosynth MIDI is a powerful MIDI prototyping platform that converts incoming MIDI events into electrical signals that make experimentation very simple!

This is a small footprint SMT low voltage audio amplifier that is great for hobby level projects, instruments, and radios!

This is a passive summing mixer which takes 8 inputs and puts out 1 output. We have used this in audio applications.

This is a digital to analog converter. It takes a 7-bit digital value from 0000000 to 1111111 & converts it to a voltage between 0V to 3.3V

This is a volume unit (VU) meter which helps you visualize your music and audio projects in the shape of a mini speedometer.

This is an array of 8 AND gates where one input is user-provided and the other input is provided by a serial to parallel shift register.

This allows you to control 8 NPN BJT transistors from one serial to parallel shift register to drive higher current loads.

This allows you to control 8 items (ie. LEDs) with one serial to parallel shift register to drive low current loads.

This is a candle simulator which simulates a flickering flame. It also simulates a flame blowing in a gentle breeze.

This is 1/2 of an IR system. The transmitter communicates with your TVs or IR destination and can be controlled by multiple IR inputs.

This is 1/2 of an IR system. The receiver receives IR inputs and allows you to drive one or more IR transmitter kits.

This is a Raspberry Pi shield providing you with 32 - 5V outputs controllable via software running on your Pi.

This kit is a great beginner's kit for learning about transistors, capacitors, and resistors to create a dual LED blinker.

This is a cute wine-shaped breathalyzer that allows you to visualize alcohol content with rising LED "bubbles"!

This is a handy adapter that allows you to command and control MIDI devices via serial communication over a standard MIDI cable (5 pin DIN).

This gives you breadboard access to 2 stereo 1/4" jacks and speaker terminal. This can be used for stereo, mono, balanced, or unbalanced audio.

This allows you to connect a MIDI controller to your microcontroller. You can then use your MIDI controller to control whatever you want!

This allows you to control 8 7-segment displays via shift registers with only 3 wires from your microcontroller of choice.

This is a rotary encoder kit that your microcontroller of choice can interface with and it is breadboard friendly for prototyping.

This is a low pass filter kit that allows multiple rolloff frequencies below a range of 482 Hz to 3858 Hz to pass through.

This is a high pass filter kit that allows multiple rolloff frequencies above a range of 482 Hz to 3858 Hz to pass through.

With 6 wires and this kit, your microcontroller/computer will be able to read or write to any of the LED switches via a 74hc595 and 74hc165.
