Driving HDD BLDC motor
Log from Hard Disk Drive analog and digital clock
A Hard disk drive motor has more coils than this simple triphased motor. Practically I have found 24 stable positions. The basis sequence of 6 positions is thus repeated 4 times. And 24 is a very convenient number for a clock !As we have 24 stable...

Centripetal Force and the BLDC Gyrofan
Log from TrillSat
I started to look more closely at the centripetal force equation, since I've been wary of raising the Gyrofan speed higher with its full mass, as I didn't know exactly how much force was being generated. I'd like to ramp the thing up to get appreciable...

Plan for an improved BLDC controller
Log from prism laser scanner
Rotating polygon laser scanners need to keep track of the angular position of theprism or mirror.In an earlier version of Hexastorm, this was achieved with a Sharp A160 polygonmotor. This board has a NIBC3111 chip. Motor speed could becontrolled by sending...

Distribution/connector board info!
Log from CM6 - Compliant 3D printed robotic arm
A Connector board is used to connect the S-drive BLDC driver to the 24 power supply and to the teensy microcontroller. They are designed to be stacked one on one with brass spacers.

Revised expectations and/or progressive enhancement
Log from REMB - Raz0r Electric Mountain Board
Pricing all the parts for 2 bldc motors, two vesc controllers, charger, etc for what I wanted to build here put me at about $400. That was a bit high...I have revised the plan. Do what I can using what I got on hand, and spend less than $100...

Putting together the motor driver
Log from Gator Quad
A picture story:I have completed the building of my first motor driver board. This is a prototype so it has been constructed on a perf board protyping board that I bought at Fry's electronics. This is not meant to be a flying prototype just a test bed...

A little background
Log from Brushed DC Servo Drive
This project came to be when I became tired of searching for a commercial option for closed loop position control for a CNC machine I'm developing. The majority of the retrofit CNC drives I found were stepper motor drives, and altough many brushed or...

Build hope?
Log from TrillSat
The twenty 2018 Hackaday Prize Power Harvesting Challenge winners were announced today, and again I did not win a single thing, not even a non-monetary achievement. This is the 3rd loss for TrillSat in a row, and I see a trend here, unfortunately....

Project Log 61: DIY Electric Motor⁴.
Log from DIY Mech/Exoskeleton suit.
Tuesday, 11/07/2023, 17:54. Well, I believe this will be my last project log on "theorics" of electric motors, and if you didn't notice, that's more or less "my last attempt", first I will list everything I need to do, then later I will make project...

[R] Sourcing chips
Log from Tetrinsic [gd0041]
Yikes. This took 8 hours to curate. At least now I know I'm creating a switch that's likely to be >£15 per each. Considering that many ergo keyboards, the Twiddler3 and the Charachorder all cost north of £150, this isn't too terrible. Behind...

[R] Are better components now available?
Log from Tetrinsic [gd0041]
[20 June: 01:00] So I stopped daydreaming about the T9 Plus mini PC inside #Leti and went onto Digikey to confirm prices of components. Unexpectedly, prices have changed. The TLE5501 was over £3 last time I checked, and the AAT101 was...

[M] PCB Schematic
Log from Tetrinsic [gd0041]
[22:50] Ok. I've spent the past 2 days drawing up this schematic. The license is going to be under some permissive option but I've just been reading datasheets and connecting the dots so...It's a good thing that I haven't just press "Buy Now" on...

[T][R] Concept Fantastic4
Log from Tetrinsic [gd0041]
The next Tetrinsic concept was going to be "Tetrinsic Concept4", but partially because this project needed a hero and partially because I was thinking about the intro music from the 33 second mark of the Fantastic Four: Worlds Greatest Heroes as...
