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...

Current sense method used
Log from CM6 - Compliant 3D printed robotic arm
Good read about this topic and where i pulled most of the data: https://www.st.com/resource/en/application_note/an5423-current-sensing-in-bldc-motor-application-stmicroelectronics.pdfIn this project, I used the simplest current sensing method and that...

[T] Looking ahead: USB Type-C system
Log from Tetrinsic [gd0041]
Right now I'm just looking further ahead at the Tetent implementation to see if there's anything else that would be required to connect to a Tetrinsic that can't go though I2C.Essentially, the part that'll likely be called Tetent PCB is a PCB that has 2...

First testing until it blew up
Log from I2C Controlled, FOC capable BLDC controller
I got the boards, soldered the components, and fired it up. Nothing blew up then, but the motor did not work. After adjusting some i2c settings (including turning off OCP (which was not the best idea (although that's what made the motor work (although...

Week 1: Research and more Research
Log from My Journey of Building a Performance Quadruped
I have a huge project ahead of me, and in order to be successful i have to be as prepared as possible. I began looking into a whole bunch of open sourced quadrupeds. I mostly only looked at mammal like robots with two sets of parallel limbs. Not the...

1. Motor selection and control
Log from StrobeTuner
The heart of a strobe tuner is the strobe disk, driven by a small electric motor. It has to spin pretty fast (thousands of RPM), but the only mechanical load is inertia and air drag. The angular speed has to be very accurate and stable. These requirements...

PCB motors suited for laser scanning
Log from prism laser scanner
Abstract: PCB motors seems suited for laser scanning; - speeds seem sufficient - cross scan error is not affected by pcb coils Angular stability needs to be improved but this is seen a relatively trivial issue. Video: Measurement...

Log V: The Pandemic Strikes Back
Log from Open Source Spherical Motor
In a week things move fast! Since my last log the university has shut-down almost entirely (extending and then moving forward the Easter holidays) and the chances of actually manufacturing my design look increasingly slim ... Not least because I'm already...
