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...
Finally had sufficient time to post a demonstration video amidst end of semester chaos. I learned that I've got pretty shaky hands / should not pursue a career in film-making so if you want to see what the Tea Pi would look like during a minor earthquake...
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...
Somewhere amidst the flood of stuff that needs to be done I found a few minutes to sit down with a few parts, a soldering iron, and a rough idea of what I wanted to end up with(see the schematic in the last log). The results are shown below. Note the...
It's about time I got an actual schematic on here. This is likely to change a little as things develop.I've also got the audio output part working now.I am pretty new to audio circuits and the little I do know comes mainly from datasheets and schematics....
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...
Seven years might seem like an eternity in the world of technology, where trends change in the blink of an eye. Yet, after enduring millions of keystrokes, weathered the presence of food crumbs and defied the rigors of unforgiving electrostatic discharge,...
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...
A loud alarm pulled Lee from his much needed slumber. He sat up instantly, adrenaline pulling his reluctant muscles off the thin bunk. His eyes darted between the three others who shared the sleeping quarters while his mind shook off the haze of sleep....
Jitter! How'd I forget Jitter? This, I'm pretty certain, is not typically specified in most era-datasheets. In fact, as I recall, it's [now] mostly only specified in *receivers*, as in "how much jitter will this serial-data input tolerate?" As opposed...
Micrometeorites are tiny little rocks that fell from the sky, and they're actually pretty common: on average, about one falls on the earth's surface per square meter, per year. Finding them is quite easy, too, if you live in Antarctica ---...
Since my last update, I took the four complete 3D printed stones and gave their surface a rather sharp makeover. All those years in art school came in handy again. It surprises me just how many techies have never heard of gesso … so I'm tapping this...
Here's a draft I wrote but didn't publish because of the rant at the end. But, it is what it is, just beware. Maybe skip the last couple paragraphs.----- Briefly (hahahaha): What it does is breaks the entire track down to its MFM-representation. For...
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,...
