The Mini Metrology Lab - Conrad Hoffman

His "Electronic Mess" section has many pages on repairing and restoring old instruments and equipment.

An Excerpt from his pages is a Reading Pleasure due to his rich experience and enticing language. 

Troubleshooting Audio Electronics
I ain't gonna lie. You won't be a master troubleshooter after reading a couple pages here. Hopefully, what I can do is give you the ability to form a logical plan of attack.

Troubleshooting is done mostly with the mind, not with the soldering iron. We all have problems that get the better of us, at least for a while, but approaching the situation as an interesting puzzle, rather than an unpleasant task to be suffered through, will make the work go quickly.

 Success will come from a 3-prong approach, a combination of understanding the circuit, having the means to test it and being in the right frame of mind to correctly interpret the test data. Never underestimate that third component.
He also has a Design and Testing Services called  Deep Run Design.

Meggy Jr RGB is a new kit that we designed as a platform to develop handheld pixel games. It's based around a fully addressable 8x8 RGB LED matrix display, and features six big fat buttons for comfy game play.

A unique feature of Meggy Jr RGB is that it is designed to be mounted inside a “handle set” — a wooden or plastic case that’s safer and more pleasant to hold than a bare circuit board.

RoboBrrd from RobotGrrl Erin

RoboBrrd is an animatronic character designed to be utilized as a tangible physical interface to interact with learning applications for elementary school students. A Smart Robot Bird. A Edutainment aid Bot Avian.

Impy RoboBrrd - Nicknamed 'Impy', short for 'Important'. This is the latest RoboBrrd, and the official prototype that sparked the creation of an Instructable and intense documentation for the RoboBrrd robots! Impy uses a standard Arduino as a brain and has a NFC reader to see what hats it is wearing.

With RoboBrrd being a tangible physical interface, the students will interact with RoboBrrd to control the in-game character within the learning application, and RoboBrrd will motivate the students to keep playing with chirps and celebratory dances. Different behaviours in RoboBrrd will be unlocked for every level that is beat,
