OS Upgrade and introduction of WiFi enabled device
Log from Open Indirect Ophthalmoscope
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...

Removing undesired reflections/spots
Log from Open Indirect Ophthalmoscope
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...

Design Considerations
Log from Open Indirect Ophthalmoscope
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...

Early notes
Log from CalendarClock
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...

Board pliers MK 3
Log from How lions etch PC boards
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...

Designing for Calibration
Log from 60W CO2 Laser Cutter Mk2
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...

Purchased Hardware & Electronics
Log from Delta 3D Printer
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...

Day 1: Mechanism is good, no bubbles yet.
Log from Fan powered bubble machine
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;...

Gear design
Log from Strain Wave Gear with Timing Belts
This is based on the design of a strain wave gear, but it not an exact copy of a strain wave gear. Strain wave gears characteristically have an oval wave generator, a flex spline cup, and a circular spline. The wave generator engages 1/3 or more of the...

It's a kind of magic...
Log from MPRT - Modified planetary robotics transmission
I'm beginning to deduce some of the magic required here to make the gears mesh. I stumbled upon a compatible gear set by accident originally, but now I think I understand what is actually going on. The rules: The sun gear tooth count must be divisible...

Got X-Rays
Log from 100$ Xray desktop CT scanner
Got X-RAYS, yeah :-DIt works fine. I get a smooth nice green glow on the scintillator screens.It works with car engine ignition coils and an old radio tube (there are plenty of them on ebay, from 50 cents to 3€)

Next version from Proof of Concept
Log from Strain Wave Gear with Timing Belts
I just want to get this in so we know it's been tried and seems to be an improvement over the version in the first video: The proof of concept constrained the timing belt along one edge to a circle. When the wave generator moves past a section of the...

Updated Drive System
Log from GoKart Tank
After much introspection, it looks like I am going to make some changes:3D Printed drive and idler sprockets at 17 teeth instead of 113D Printed road wheels (yes, printed), but also at 17 teeth, that will raise the chassis of the tank higher off the...

Bipolar [Single/Micro-] Stepping Thoughts, ctd.
Log from CD/DVD mechanisms and cartesian thinggie[s?]
Alright, a tiny bit more research...This is a good resource:http://www.allaboutcircuits.com/textbook/alternating-current/chpt-13/stepper-motors/Here's a "Hybrid Stepper Motor" (simplified), (from that page):(simplified, further:)"Hybrid stepper motors"...

Axle Holes
Log from Go Kart Tank (formerly Half Track)
I found that I had to force the large threaded rod axles in very gingerly. I didn't want to wreck the wooden frame. I also realized I should cover the wooden frame in fiberglass when I was done. I made sure that the distance between the 2 rear axles...
