After I sketched The HMS board, @K.C. Lee made a pertinent remark about another use of these boards for dividing the 18KHz source down to 1Hz.Two HMS boards divide by 60, each, or 3600. Only a factor of 5 is needed to get 18000Hz. This reduces the overall...
First off, a disclaimer. As with much of my work as a sound designer, the ideas I develop (or at the very least the roots of the ideas that I develop) come from external sources. When I first learned of the gallery staff's issue with sound in their space,...

Last night I talked about my adventures with ESP8266. In that project, I used the analog_io_lib to receive RF packets from a sensor node and forward them on to data.sparkfun.com using a http get request. This approach is ok, but I really much prefer...
We will begin by placing all the elements required for building this wind turbine including links for where to buy at very competitive price the DC motors that will work as generators and the bearings. - The number of bearings that are needed for the...
So, after the last test with some through-hole BJTs, I spun a quick PCB to test faster SMD transistors. I had some BFU550A's on hand, which boast an 11 GHz ft compared to the 900-2000 MHz range of the KSP5179's. The output connectors are on the bottom...
*Sudden burst of motivation*The last couple of nights I've been working on my hack of Megaman X and doing some planning with regards to different arcade modes. I've included my notes thus far.Also, I finally got around to posting the source code for...
Why reverse engineer file formats?Besides the fact that binary file formats are so last century, people use version control more and more to keep track of design document changes . Rationale that text files are big is very weak, as you could just zip...
I am not a student or organization so not eligible for the 3d printer prize. In fact I already have a Prusa i3 MK3 and it's an awesome printer, made from many high quality 3d printed parts, a great choice for the prizes for this contest.The...
A small revisionWhile thinking about the features below, I realised that I needed separate signals indicating the most significant word of an operation and forcing the memory address to be odd, so I renamed the signal I was previously calling MSW...
I found a way of storing 9 bits of information within 8 bits. Morse code has 1 dit or 1 dah up to a combination totaling 6 bits of information. I decided that I would represent a 0 as a dit, and a 1 as a dah. Then I decided I would use the lower 3 bits...
Ok so now that I've gotten to the good stuff, I first started looking at the IC's. The first one I notice was one labelled NextNet wireless expedience-AMOD D1GJ9-010. This one was a bit hard to find any kind of information on at first so...
The Plan The idea is to take this once, pan/tilt camera mount, and turn it into a alt/az mount for tracking satellites, or just about any other celestial body for that matter. Sounds simple enough, and I think it might be fairly straight forward...
