This was the most important part for me because I wanted a variety of target options. This is what I had to work with and this is what is does:1. The ancient Vivitar flash slave is only triggered by a flash from a camera (or staff flash in this case)...
Here is the register before starting:It was really easy to take apart. There were only two screws on the back holding it together. Once I took them out, I was able to lift the plastic part off the base and disconnect the wires from the main board, which...
OverviewThis is a scientific calculator I built that uses RPN notation. Features:BCD number format with 1-255 placesInternal accuracy configurable from 6 to 32 decimal placesTwo separate 200 level stacksOptional scientific notationFunctions: (a)sin,...
This is the basic design for the VPO (Virtual Pipe Organ). The white boxes are organ components, the purple boxes are custom modules I have designed. MANUALS The organ will have three manuals (keyboards). While the M-Audio Keystation 61es devices have...
I had wanted a better way to turn pages of sheet music for years. Finally, I realized I could use an old laptop to display PDFs, and turn pages with a foot pedal. I was just starting to get ideas of how to make this around my birthday last year, and...

The first step was finding some pictures of a computer to know how the keys should look. One of the best places to look for MSX stuff is MSX.org where I could find some pictures of the PV-16. Knowing how the keys should look I took some measurements...
The Motivation: Over the past couple of years, there has been a movement for music instrument companies to release “toy synths”, such as the Teenage Engineering OP-Z and Korg Volca Series. These toy synths are generally much smaller, cheaper,...
The second printing of the chassis came out perfectly. It meets my initial goals, but I'm already considering potential improvements. Isn't that the way of prototyping? Truly, I have gone mad with power. 1. I can add full-depth cutouts...
Building a replica of the Jupiter ACE has been done before, and the super accurate replication of the PCB by Grant Searle is probably the best example. The schematics were redrawn later by Bodo Wenzel in ORCAD, and a modified version was made...

How it Started Originally made as a portable wearable display into VR, this is a project that evolved into being an actual PC separate from VR, but can mesh with a VR headset as I'll outline further in this article. 1. What is it? This is a modular...
The Mattel Aquarius home computer was released in June of 1983 and had already been discontinued by October of that same year. The short lifespan of this machine is no big surprise — it is equipped with 4 KB of RAM, which is reduced to 1.7 KB of free...
The revised PCBs arrived earlier this week and later the same night, I was holding another fully assembled 4chord MIDI piano prototype in my hand. Moment of truth has come: will this finally be the revision I'm happy enough to share it with the world...
Ideation Now that clear needs were found, it was time to brainstorm ideas for media technology innovation to positively improve these points. The question was: What device can be made to control media in tune with or intelligently in leading of...
