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...
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...
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 first two prototype was just figuring out the frame and kinematics . I didnt want the the pen to have any kind of ugly wires hanging outside which would be the case had i used a normal solenoid or a servo to lift the pen. To avoid that i used a h-bot...
Many people who have aphasia cannot grip a tiny pencil. A common adaptation to a pen, pencil, or artist's paintbrush is to fatten it up to make it easier to grip. This 40mm x 150mm cylinder has a 9mm hole in the middle to hold a standard "Bic" pen. It...
How not to make a spot welder penMy first attempt at making a spot welder pen has failed.I bent the electrode ends of my existing spot welder pen inwards, then smashed them flat with a hammer and flat-end punch until they were about the thickness of...
Since prototype 1 I made the following improvements:Actuating nose of pen instead of butt because the nose is lighterHand crank on opposite sideCams facing forwardScrews have less threads per inch for easier printingCam design Cams are now designed by...
Summary about 4:00 pm, Monday, January 21, 2019 Soldering stuff together. Out of fear of destruction, this was done in steps, testing along the way. Deets First, the NodeMCU board has pin headers soldered on (or at least mine do). These aren't...
Couple minutes ago I finally get the USB HID work ! By changing the USB device name from "Wacom Rip off" to "Wac0m Rip off". I still had no idea why this change make the cursor actually move (as I said earlier that the "evtest" did shows event report)....
I finally make it working (at least on Windows 10). I already committed to my GitHub, so the latest code is now working! Also, I'm now understanding the way to report the correct hid event, so let me guide through. the number in parentheses corresponding...
So I bought a 3D pen to try and weld the 4 bezel parts together.This is the test run on some prototype prints. I'm amazed by how easy this was and how sturdy the result actually is.Final result (bezel only) will be ready in a week :D
In case someone else is playing with this. The CRV001 has an ATMega128 MCU (fewer timers), a 1x16ish LCD. The steppers work the exact same, the pen test sketch doesn't work at all (it's doing something, but I can't tell what) and the LCD sure seems...
SHOULDER and ELBOW The 2 main articulations (shoulder and elbow) are equipped with stepper motors. The transmission uses toothed belts and their pulleys. These 2 articulations are very rigid. They are made with 3mm aluminium sheet, and braces made with...
Every week is science week at Makers Making Change. We really hopped on the science train this past week, though. A Visit from the Minister On April 12th, we were thrilled to welcome the Honourable Kirsty Duncan, Minister of Science and Minister of Sport...
