As using an optical mouse sensor doesn't seem to be a good idea, I decided to work on my V1 prototype instead. I added support for joystick HID, and not just a keyboard, so it can really be used in something else than emulators. I wrote those modifications...
Designing and building TMD-2 was a great "stretch" experience for me. For the hardware, I had never worked extensively with the Raspberry Pi or Pi Camera. On the software side I had never used Python or PyGame before. So I learned a lot ...
Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
We need a a means to measure respiratory pressure for our wind controller. So which one should we choose? What are our prerequisites? Are there different kins of sensors out there?To mimick a wind instrument best, we would have to go with a flow sensor,...
We made some major discoveries! Having experimented with laser-cutting housings for our LED clocks, (placing the two breadboards back to back), we found that LEGO technic 4.8mm holes can fit 5mm LEDs perfectly in the holes, and then we can just jam the...
I started getting the TX2 all set up by updating this and that and ensuring OpenCV was wrapped by python3. I chose the reading a book as the first one to take a crack at and made some good progress or at least I know where I need to go from here....
Whilst impatiently waiting for the optical gear to arrive from AliExpress, I did a bit of looking around on the internet for things related to Mixed Reality. It's not strictly TyMist related, but with all the different systems I'd need to design...
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
Can't find a way to add files to the project, so I'm just going to paste below - sorry. First is the BASIC program, then a text file I wrote to document the code. My apologies to anyone who tries to read this; I have no experience with BASIC.Here...
Well, it turns out that BASIC strings can be at most 255 bytes long. I was trying to keep all of the labels from an assembly file in one BASIC string, which meant I couldn't have very many labels. Below is an updated BASIC assembler which...
Today, the NeuroBytes project takes its first baby step into the 21st century.Okay, ignore the extremely sketchy construction techniques. It's an STM32F0 Discovery board, chosen due to its extremely low cost (under $10) and built-in ST-LINK programmer....
So we had an idle Friday afternoon here at SupplyFrame HQ and our evil overlord Alek asked us to build something cool for the office.With the restriction of only having a day to build we didn't have many choices in what we could source components for,...
Now that we had most of the LEDs it was time to start fixing them to the backboard.First off we hot glued all the LEDs into place on the backboard which was a sheet of plywood. This took a little while but John P, Tom M, and Albert all pitched in and...
Now we wanted this display to look really sweet since it will be on our office wall for some time to come. To make it look gorgeous we decided to make the frame out of white foamed PVC board, and the front diffuser out of 1/4" thick white acrylic.First...
To drive this system we decided to use a Raspberry Pi and Arduino Micro combination.The Raspberry Pi runs a stack of Nginx, Memcached and NodeJS which then feeds desired LED colors to the Arduino Micro which streams them out over the WS2811 protocol...
