The design models have been 3D printed and assembled. We made two devices, only the outer casings are different in the two models. One is printed on a SLS 3d printer (Nylon PA-12) and another one with an FDM 3D printer (PLA Black).Both the models are...
This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
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...
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...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
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 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...
Finally Ivan screwed the backboard into place. One of the great things about using Foamed PVC is you can basically treat it like wood, it holds a screw well and is easy to cut and saw.With our fingers crossed we switched it on, and to our delight we...
The display is looking great, but we really need to make this into more than just a pretty rainbow colored matrix.To do this we decided we wanted to be able to open up the control of the lights to all our developers, and we want to be able to feed data...
With FLED we are trying to make a visualization platform, somewhere all our apps and monitoring tools can send data and where we can then use that data to make interesting visualizations.As such we need to be able to accept data from a variety of sources...
In the original FLED implementation we had a Raspberry Pi inside the case. This Pi ran a NodeJS application that executed the animation code written in JavaScript and provided a web interface for users to create animations within. This all worked fairly...
Finally, after much fiddling around, the upgrade to FLED is operational.We're now running a grand total of 1768 LEDs, in a 52x34 configuration. The setup is a Beaglebone Black connected to an RGB-123 48 output cape. The cape level shifts the Beaglebone...
So after you have a working LED matrix, you can't stop there. Otherwise you just have a big display running strandtest and that frankly just sucks.We built a Javascript animation engine that we use to drive the display, this runs NodeJS which allows...
This entire project is a little bit of an odd bird. In terms of electronic sophistication, it’s not too different than any of the other homebrew computers you might see on Hackaday. This isn’t a project that will just sit on my workbench until I die...
