Back to design.
Log from Point-to-point SMT Transistor clock.
I spent a few days soldering parts together trying to rearrange the schematic in my head to make building easy.I made plenty of nonworking flip-flops, so I went back to basics.1) Install KiCad2) Enter the schematic of one flip flop3) do a PCB layout...

First Update
Log from Breadboard Test Leads - Rev2
I ordered some samples of the components that will be used in Rev2. They will arrive in about 1-2 weeks.The current price point for Rev2 is around $14.With the current timeline, Rev2 could be in production around mid-August or early-September. I plan...

Experiments in Wheels: Part 3
Log from Micro Robots for Education
Hello, once again I am here to talk about wheels, don't worry, next time will be something different, but for now, it is wheels. First the video, because hell why not:The wheels that I have settled on are made with a DLP driven, resin curing 3D printer....

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...

Experiment in Wheels: Part 4.
Log from Micro Robots for Education
Hello, So it seems the core issue in this project is how to reliably make the wheels. The resin 3D printer I used before made some ok wheels, though the tolerances where not reliable, also as the optical path became foggy the quality of the teeth degraded....

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...

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...

Tracks!
Log from Bot Matrix
OK, another weekend, another subsystem. This time I've been working on a prototype for my tracks module. The robot will be tracked (tank, caterpillar whatever) - I bought some rubber tank tracks from Aliexpress (type D), and assumed I would sort...

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...
