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...

Donor Cabinet work
Log from Star Trek: The Mirror Universe Pinball
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...

8/30/2020 initial test powering boat
Log from solar powered boat
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....

Gear ratios
Log from Crazy Clock
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 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;...

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€)

Measuring Magnetic Fields in a Volume
Log from low-field MRI
Let's have a look at the first test rig for measuring magnetic fields over a 3D volume.I confess that I've been thinking about this for a few weeks, and it's been a fun (and sometimes frustrating) design process. We'd like to accurately map the magnetic...

Putting all thogether
Log from Mini WiFi/BLE 4WD robot platform
When the controller and the housing are assembled the wheels can be placed. Therefore the gears with 8 teeth (6 pcs.) and 12 teeth (2 pcs.) need to get equipped with a brass axle. A 3mm brass rod can be used for this and will stick well in to the gears....

Plier stand
Log from How lions etch PC boards
Even better than PC board pliers is a stand for dunking them. Lions always used surface tension to float the boards on the acid, but this should eliminate air bubbles. Helas, the pliers now need a place to put a rubber band & a place to clamp onto the...

BitBeacon Stops Working When Outside
Log from Bit the RoboDawg
Wednesday, June 8, 2016Tested Bit outside. It appears the BitBeacon stops operating outside. Not sure why. We have used outside plenty of times. We did make a very minor modification to Bit since the early Bit demos at night, but still..... Anyways,...

proof of concept using Fischertechnik
Log from simple pick-and-place head
To see if the idea works at all I started with a quick build based on Fischertechnik and some hot glue. The small Fischertechnik gear "Riegelscheibe Z20" fits perfectly on the 4mm part of the Luer connector. It is actually a gear with 20 teeth, modulus...

5/8/23
Log from Color Spectrum of Feelings
We settled on our spectrum design. Our 3d printer isn't big enough to fit the whole 3d box so we had to print it in two pieces. We waited to print both pieces until we decided on our final build. When we tested our servo moving across we found that the...
