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...
I've been making progress on the CAD modelling for the project. I've got a draft model of all of the hardware at this point. This weekend I'll start printing/testing components. I decided to go with a double herringbone gear for connecting the yaw...
Today I managed to test the motor after tightening the belts considerably so they wouldn't skip teeth. I had to hammer the pulley on the shaft to get the higher tension, so an adjustable idler pulley on each belt may may more sense in the future....
So this log is unique to my project. Using a diamond bit, I drilled holes in some of my old wisdom teeth. Using hot glue, I am fixing them to the buttons for the warp and feedblast mods. (TD404-Tooth Decay404)
This is retroactive notes, based on memory of this project Here is an early test (april 2019) done with the gear changer. At that point I presumed a single axis could hold the gears, but there was too much play up/down so the later design holds the gears...
Then came board pliers MK 3, featuring bigger grip teeth, a handle ratchet, more aggressive slider ratchet, more curves to aid cleaning, a handle extension to clamp onto a stand, 5mm thick pieces. The ironing process yielded a marble like finish on...
I'm going to label these two gears of interest the "inner" and "hour hand" gear. The hour hand gear is the one with the stem riser that winds up accepting the hour hand. The inner gear meshes on its outside edge with the minute hand shaft and on the...
Designing parts to fit perfectly together is hard. Whether it's the coarseness of our fabrication tools or that of the vendor selling us these parts, nothing is perfect. Engineering has cute word for it: tolerances. Maybe it's me: "I can drill that hole...
In order to stick to my design goal of an AUD$1000 budget I decided to start a bill of materials spreadsheet. This would be a handy tool to keep track of budget and also allow me to show people if they wanted to try making something similar. Below is...
The goal for day 1 was to make a mechanism with LEGO studded beams and gears to convert speed from one axle (where the pinwheel will be) to strength at another axle (where the bubble wands will rotate). The mechanism completed on day one is a 1:36 ratio;...
