Why did you make it?

As a fellow maker/hobbyist, I have come across multiple frustrating tasks that have slowed down my tinkering process. A few examples...

Before adding an LED to your circuit (SMD or Through-hole), it would be nice to have a way to easily test the polarity and that it works. When pulling a random resistor from your large unsorted bin, it would be nice to quickly test without fumbling with the contacts of your multimeter or looking up the color code. Trying to probe parts of your circuit on the breadboard while viewing the multimeter output can be cumbersome so I was looking for a way to directly wire the probes to any part of the circuit. When working with various microcontrollers and sensors, switching between logic levels can be a hassle. Every once in a while I need a push button for a circuit and never seem to have enough room on the breadboard so I was looking for an easy way to add a button without the hassle of wiring one up.

Because of these frustrations, I wanted a solution, so why not make one! I designed a compact, versatile multitool that solves all of the problems above and more. It has been incredibly useful in my tinkering and I wanted to share it with the rest of the world.
