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...

Roller Chain vs. Belt Drive and New Belts
Log from Goliath - A Gas Powered Quadcopter
The last time I wrote I was getting ready to add additional pulleys to try to deal with the belt oscillations. Over the Thanksgiving break, I had some time to think about it some more and came up with some alternatives. One of the first things I did...

[T] New Harmonic Drive Ideas
Log from T^2 Tiles [gd0095]
Looking at the current file, the Tile sticks out of the wall by 140mm. I think it's possible to reduce this to under 100mm. To do this, I need to design an even smaller harmonic drive, yet with high durability, low load displacement (high torsional rigidity)...

DC27 DOOM SAO - Hurt Me Plenty
Log from AND!XOR DC27 Badge
We’ve been lucky this year to have Cr4bf04m on our team, aka LonghornEngineer, aka Parker Dillmann. He shared our goal of the DC27 project to make the badges free during hacker summer camp. Aside from philanthropist backers and generous sponsors (Urbane...

LVDS Board
Log from Portable Pi/Emulation Station
I have seen an LVDS converter board for around 20 dollars on e-bay, and I think this might be my best option, as I have plenty of old laptop screens around, and I'm losing faith in these cheap chinese screens as a long term opton. Also, this would allow...

Another look at battery discharge curves...
Log from The Cave Pearl Project
Sensor failures almost always show up as a hit on the battery discharge curve, but there are plenty of other things that show up on the graph for loggers that are still working: Another look at battery discharge curves...I will add more of these plots...

All systems are nominal
Log from LoRa darkStar
Finally, the timer chip and associated logic gates are working at all time intervals right across the full range. The timer and logic circuit is shown in the photo above and occupies a footprint of 20 x 15 mm. There's plenty of opportunity for a bit...

Hypocycloidal gear with timing belts?
Log from Strain Wave Gear with Timing Belts
Is this the next logical step? I was surprised by the torque efficiency of the hypocycloidal gear I made in the Hesitation, Repetition and Deviation log, so perhaps it's worth pursuing for a bit. Until today, in conversation with @Dan Royer I...

I did it, I designed a gearbox assembly to get rid of that pesky belt
Log from Mr Pancake
So, I figured out how to do gears in Fusion 360 and I made a prototype of a new mechanism to transfer power from the stepper motor to the axle and combined it with the mount for the x axis rail.I've still got a few more bits left to sort out, I have...

Drive and angle measurement considerations
Log from Low cost Robot Localisation System (LRLS)
The SRLS determine the position only based on an angle measurement. As further the robot is away as more demanding such a angle becomes. E.g. the robot is 5 meters apart from the SRLS one degree of error result in a 9cm positioning error. This isn’t...

CAD Changes 13.09.2018
Log from 3D Printed Strain Wave Gear
I just updated the CAD-Files. Now the Circular Spline and the housing are two seperate entities, this allows for a fast iteration on tooth profiles as one doesnt need to print the biggest part of the assembly over and over again. Instead of a dovetail...

Version 5.1 Posted
Log from GPIB Instrument Control Console
I picked up a newer (as in still in production) instrument for my bench and had problems getting it to talk. After lots of teeth gnashing and resorting to Wireshark to dissect the USB I found that subtle changes on the GPIB bus were causing the Prologix...

ROV bus cable penetration
Log from BorgCube ROV
I'm using IP68 8-contact connectors to connect external systems (e.g. robot arm) to the Raspberry Pi board. To do this I need to run these connector from the wet side into the dry pressure vessel. Do do this I'm using the Cable penetrators from Blue...
