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...

1) Mechanics
Log from Scribing Robot
SHOULDER and ELBOW The 2 main articulations (shoulder and elbow) are equipped with stepper motors. The transmission uses toothed belts and their pulleys. These 2 articulations are very rigid. They are made with 3mm aluminium sheet, and braces made with...

Motorized Caster
Log from VR Locomotion Concepts
I had an idea for a motorized caster yesterday and spent some time making a model of it. Up until now I haven't found a motorized caster or thought of one that I think would be small enough and powerful enough for a VR shoe. But this one might be.It's...

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...

Z axis belt clamp fail...
Log from Belt Lifted Z-Axis for a 3D Printer
The Z axis was recently behaving strangely. I noticed the belts were flopping around so I retensioned them. In a couple days, they were flopping again. I took them off the machine to see what was going on and instead of finding that...

Gear Note
Log from Servo50: Scaling Servo-Based Projects
I've been trying to find the inspiration for this style of gearbox - I think it was somewhere here on Hackaday, but I can't find it any more. If you check out the Wikipedia article on Epicyclic Gearing, there's a small note on a version of what...

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...

Self Aligning Mating Gears
Log from Multitool 3D Printer - Blackbox
The new tool changer uses the Bondtech Extruders 1:3 reduction to decouple the extruder from its motor. To make this work, the gears need to be aligned at any time (which sounds easy but it's complicated with open-loop stepper motors). Another solution...

Panic - Plan C
Log from Tired Clock
Time is running out. Only 1 (One) Day left, and other things have to be done, too.I reveiwed my options and time/effort, and suddnly a 3rd design struck me - with no change to the electronics and a true "flop down" of the hands.The blue/pink gears have...

Battery swap - part 1
Log from mEgaTON Radio
So it ends up two of the four batteries I got are dead. Thankfully, I have plenty of enloop batteries around to test. I wired up three to get my 3.6v (4.2v technically, but that will drop as they discharge), and the radio seems to work just fine. I do...

Step 1: imaging the eMMC SD Card
Log from Linux Tutorial: Odroid U3 Server w/ Seafile Cloud
This step is just downloading and imaging the card. I use SD formatter to be able to format the cards and WinDisk Imager. I do not want to go into to much detail as there are lots of tutorials on how to do this. If you are working on a net server then...

Power & battery
Log from Light bottle
I tried to experiment with AA battery instead of 18650 Li-Ion. The design is slightly smaller and lighter, but I think it will be worse on the long run. 18650 can provide more power and it's easier to have step up and charger on the same board.I recycle...

Sensors and camera
Log from Autonomous watering system
The Raspberry Pi board has plenty of GPIO lines available for hooking up sensors such as DS18S20 1-wire temperature sensors:http://www.raspberrypi.org/forums/viewtopic.php?f=44&t=65137I might also hook up a soil moisture sensor (measuring capacitance)...

Need to make this more compact
Log from Motorcycle Rear Vision Helmet Mounted Display
while I'm waiting I have plenty more todo. All this gack is going to be packed inside my helmet somehow so I'm thinking of making everything smaller (except the screen). I'm going to chop off all the excess wiring and disassemble the RX unit to see if...
