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...

Here we go again.
Log from P2 - Pick and Place for 3D Printers
While I'm waiting for my Jetson to show up, I'm starting with the other stuff.I've been doing a lot of research into accurate open-loop positioning of BLDC motors. If there ever was a perfect application for this, part rotation is it. Basically...

A new timeline
Log from P2 - Pick and Place for 3D Printers
All involved with this project have been unable to dedicate the time required to move this forward. As such, we have adjusted our expectations to complete this... sometime. A mass of different BLDC and micro stepper motors were ordered on the slow boat...

SIMPLEST WAY TO CONTROL A FAST BRUSHLESS MOTOR WITH RASPBERRY PI USING SOLO [+ CODE]
Log from SOLO, A Motor Controller for All Motors
We just published a new article, demonstrating the Speed controlling of a high-speed Brushless motor using Raspberry Pi and SOLO by coding in Python.There we show how easily you can interface Raspberry Pi to SOLO for Closed-loop controlling of a BLDC...

Connection scheme
Log from CM6 - Compliant 3D printed robotic arm
BLDC drivers are connected to connector board using modified IDC cables. More can be found in this folder: https://github.com/PCrnjak/CM6_COBOT_ROBOT under building instructions RX1 = PIN0TX1 = PIN1RX2 = PIN7TX2= PIN8RX3= PIN15TX3 = PIN14RX4=...

ESP32 HDD clock schematics
Log from Hard Disk Drive analog and digital clock
As promized, I am just starting to port my HDD clock on a new MCU : ESP32 This would have several adavantages: wifi and bluetooth are enabled. No need to connect to a PC via USBESP32 lolin lite breadboard has everything needed: power supply, battery,...

The Payload
Log from Open esk8 Remote - v1
Let's take a quick look at the payload the remote is sending all the time. In fact I saw multiple payloads and I can't yet figure out what they all are for. Everything in green is what the remote sends to the motor controller. There are two types...

Testing bidirectional control
Log from Modified ESC for Bidirectional BLDC Control
Success! We managed to get bidirectional control with an off-the-shelf ESC!Unfortunately, the type of ESC had to be changed, as we encountered numerous issues flashing different firmware to a generic SimonK-type ESC. Instead we opted to go with a BLHeli_32...
