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...

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...

Third Time is a Charm?
Log from 3D Printed Chiming Clock
Okay the second version of the Escape Wheel was better than the first, but still was not a complete success. This time it was not possible to adjust the pallets to prevent the escape wheel from free running, or jamming. And of course that means that...

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...

[T] Minimum radius issue!
Log from Tetrinsic [gd0041]
The current solution... may fail, due to: - turning radius requirements of the 3.2mm ball chain approaches the motorised sprocket diameter. So I've implemented some tweaks and learned a few things. Firstly, unlike what I assumed months...

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...

CNC cut test gear based on the parametric generator
Log from Strain Wave Gear with Timing Belts
I just wanted to say that I've tried cutting the HTD 5MM mount ring in my new CNC in 9mm plywood and it seems that when I place it over my first design revision there's a 1-2mm gap/play between the belt and gear. This isn't supposed to reflect at all...

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...

Mini-Update On The v2 Ratchet Design
Log from Hintha Modular Prosthetic Hand
Jason Bender // 15 Dec 2018 // Taunggyi, MyanmarAs I wait for more hardware to arrive from abroad, wanted to update on some small design changes for the ratchet system:Animated exploded view of new ratchet assemblyIf you may remember, the original...

Sprockets
Log from Modular Continuous Track System
Now that I am cranking out the treads at a much faster rate, I need to start looking into testing this design out. That means building a tracked robot. Because my goal is to test out the modularity of the system, I actually want to test out many different...

Down the Rabbit Hole
Log from MPRT - Modified planetary robotics transmission
Optimisation of the Original MPRT So okay, I decided to see if I could optimise the original MPRT. Not a trivial task, but doable with brute force: For each Pressure Angle (PA) from 15 degrees to 25 degrees in steps of 1 degree.For each Diametral Pitch ...

As the gear turns
Log from MultiBot CNC v2
Edit, fixed some bugs with the equations. --- For my rotary project I needed to 3D print a gear that would interface with a toothed timing belt. However when I tried to wing it and make one without doing any real research the belt did not interface...

[M] Hurdle hit for harmonic drive
Log from T^2 Tiles [gd0095]
Yesterday, I was thinking "I know how to model this" and started researching and modelling the new harmonic drive and looking for the components I want to use. I thought 14:1 was a good reduction, and it's coincidental because if I can get over...
