Tiptop Audio uZEUS 4HP power supply

"The microZEUS is a 4HP power supply module for Eurorack format synthesizers. It is the smallest and most powerful power supply available for its size. There are two versions available:

1. uZEUS with flying bus boards: this version features two ribbon bus boards. All you have to do is plug in your modules and play.

2. uZEUS with quick fit terminals: this version features four standard spade terminals to connect to rigid bus boards like the ZEUS Passive Bus Board.

The uZEUS mixes linear and switching power technology to produce 1000mA at +12V, 500mA at -12V, and 170mA at +5V and uses a standard +15VDC non-regulated wall adapter for power."

DIY Arduino Based Ribbon Controller

via Giuseppe on Coagula

"There are many professional MIDI controller out there: keyboards, drum pads, mixer, pedals, etc. One type of controller that interests me most is the ribbon controller because I wanna try to emulate with the software plugins what can be done with instruments such as the Ondes Martenot. I think that this type of controller fits very well to control virtual instruments such as strings and horns, as it is characterized by a position and pressure sensitive ribbon, so you can control in a very intuitive way the notes pitch and velocity. I decided to do a MIDI ribbon controller using Arduino."
