Solderless Breadboard Extendr

Now you can use your 3D printr to save even more money by buying a $50 protoboard and surgically implanting a $10 protoboard off Amazon to get the equivalent space of a $100 protoboard with the help of this Thing!

I needed a protoboard/breadboard with 4 boards for a project, and accidentally bought the 3 board model for half the price not realizing it only had 3 boards, so I hacked up a single board I had lying around, and with the added support this structure provides, I was able to connect it to the breadboards that came with the 3-board protoboard using their dovetail-like mounts.

It also has a little handle thing for modularity to add additional structures later.

For example: the circuit pictured is a multi-input amplifier so I can connect my guitar, an iPod for background music, a microphone if someone wants to do some karaoke, and there is also an area that is impedance matched for a record player to make some sweet Beatles covers. I plan on adding a structure
