New tutorial on How to Setup and Calibrate your Quadrature Encoders with SOLO!
Log from SOLO, A Motor Controller for All Motors
We have just published a tutorial on how to properly setup and calibrate your Incremental Quadrature Encoders with SOLO to control the Torque, Speed and Position of your BLDC, PMSM or Coreless Brushless EC Motors. https://www.solomotorcontrollers.com/how-to-connect-quadrature-incremental-encoder-to-solo/...

9# Manufacturing of the 5th and 6th axis
Log from Dynamic 6-Axis Robot from scratch
The 6th axis is the most integrated and thus most complex axis of the robot. In a small form factor it includes: - 12bit incremental motor encoder - BLDC motor - wave gear - 18 bit absolut magnetic encoder - bearing arrangement - peripheral connector...

Smartcar 2.0
Log from Rosmo robot
Playing around with the stacking concept in a slightly larger footprint.MoDoing a brushed version first, then swapping out the motors board for a BLDC version laterDocumentation

motor as encoder
Log from anaQuad!
Yeah! #Motor as Encoder Use a BLDC motor as an encoder. Almost *Exactly* as I'd imagined. Combine this with anaQuad, and yer all set!Note that anaQuad *also* works with two sources that are 120 degrees out of phase, so only two windings of the...

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...

v0.7 testing
Log from custom bldc motor board using fpga
For testing v0.7 we conducted two tests. The first test was to do 10000 cycles of lifting a 5kg weight up and down. The iceboard here controls the bldc motor mounted in one of roboy 3.0 muscle units. The white dyneema tendon is rolled up by the bldc...

Am I fooling myself?
Log from Droidbot 07 - Wheeled-Quadruped
Do PAMs really have much benefit over motors? Some (subjective) pros & cons of PAMs vs BLDC motors for this application: Pneumatic Artificial MusclesMotors (& gearbox)+ Powerful for their weight/cost.+ Fast.- Have to trade speed for torque.- Do I have...

Motor Simulation and Sin/Cos Encoder Support
Log from Axiom: 100+kW Motor Controller
Today some code we developed for the VESC platform was merged into the master branch, reaching thousands of current VESC users.Motor simulation inside the firmware is a critical step in our path to having the greatest controller out there.It help us...

BLDCiing it forward
Log from linear actuations for everyone!
Next logical step - is to couple theoretical findings with BLDCs, it is fun, educational and even useful at some point! In previous update that was a brushed motor... Pretty unfortunate - it's hard to imagine worse enemy than brushes with that approach....

For those with energy savings in mind...
Log from Entropy Wheel Heat Recovery Ventilator
The Panasonic FV-04VE1 is the benchmark I am competing with. These are commercially available via Amazon and other distributors. The Panasonic design is based on a "capillary core" heat exchanger. A 40CFM unit is just under $350 and consumes 23W. I believe...

Thingiverse Creations Abound!
Log from Entropy Wheel Heat Recovery Ventilator
See my Thing on Thingverse with the glue-less clip-together assembly parts. http://www.thingiverse.com/thing:485101And also a cutting tool for rapid, safe cuts of Coroplast! http://www.thingiverse.com/thing:482141Still need a high-reliability...

New ESC firmware
Log from Arcus-3D-M1 - Full Color Filament Printer
I was still having problems with getting a linear, low RPM response from the BLDC ESC.Re-flashed the simonk firmware on the ESC. I reduced the stop pulse width to 100us and disabled auto-calibration.I spent far more time figuring out how to use my new...

Brushless DC motors: overview
Log from Supercon talk: a pragmatic guide to motor controls
Brushless DC motors (BLDC) are meant for SPEED. They can get to high RPM quickly and reliably, which is why they are used in drones, mills and cooling fans. They also can provide a good amount of torque, which is why they're also used in e-bikes. They...

Arduino RC airplane
Log from Arduino RC airplane
Added two scaled drawings of the fuselage-to-be, after adapting the earlier referred to plans and mashing some other stuff in. Will probably still modify if, it is by no means a finished design.In the electronics front, will order a motor (BLDC, 12v,...

Coming Soon & Ideas
Log from STM32 Blue pill IoT expansion boards
The RF Node with sensors is up and running, the RFPIO is up and running, time to think on what should come next.Ultrasound cartography using multiple low cost HC-SR04 or 05 see Hello_Ultrasound sample for experiments.The extension board should provide...
