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...
The last log has shown the results of the latest development work, which ensures that input data are correctly pre-sorted into ascending runs as they arrive, at the cost of more than doubling the working area (which is not surprising for a merge sort)....
Project Log 7:14:29 hourse - Brasilia Timezone - 18 of septemberDunno if someone cares, but I will start taking Saturdays and Sundays to do absolutely nothing. I'm getting absolutely exhausted from the work I'm doing (not this one, of course).And to...
Video: I've made some progress on the firmware - the SD card interface is now fully functional. Also, the display font that came with the Pico C SDK SSD1306 OLED example was missing some characters, such as punctuation symbols. I substituted this...
So I managed to get a residency at the Supplyframe Design Lab in Pasadena, and hurriedly got to work on a prototype on day one!(Note that I am writing this up a week after starting and I am completely exhausted, so mostly pictures.)First up, 3d print...
As often happens, a new usage for something uncovers issues. That happened when I went to add the ability to print a banner to my retro-computer. Up to this point the printer interface had never had to print anything harder than a few...
The Z axis deviated from using the motors used on the X and Y axis. Instead a motor that was pulled from some random copy machine was used. The linear guides are some that were bought off of ebay coming from China. Not sure if I will go this route for...
The UPS-18650-NS is installed and working on my seismometer (I think.) The Raspberry Pi version that services the seismometer is a B+. The only way to know if it is working for sure is to disconnect power and wait 4-5 hours. Here's a photo of the installation:I...
Soldered up the one-shot circuitry. I'm now calling this sdramThing3.5, as it is no longer backwards-compatible with the old code without removing the chips from their sockets and jumpering some pins...There are two types of one-shots necessary:The Chip-Select...
Got the manufacturing test fixture designed, boards back and built. Now to write code. The test fixture will program code into the on-board micro (actually program two programs, the first used to find the micro's calibration value) and perform...
After much trial and tribulation, I finally having a working Bearing Gear that doesn't fall part in my hand. It's still not as strong as ABS, but it's getting closer. I would have posted this yesterday (Friday) but I was exhausted. On Thursday I was...
