Running into Issues.
Log from Arduino w/ BLDCSHIELD to run Scroll Vacuum pump
Ive been running into this issue when trying to run the motor. The company which sells the motor driver shield for the Arduino has a demo code uploaded on github, so i copied it and put it on the Arduino. The shield also had to be adjusted for this type...

Control algorithm used for motors
Log from CM6 - Compliant 3D printed robotic arm
In S-drive controller I used a 10-bit encoder. The encoder is connected to the output shaft of the BLDC motor. There is no encoder on the output shaft after the reducer. That means that one revolution of BLDC is equal to 1024 ticks of the encoder. One...

Putting it all together
Log from Rosmo robot
Rosmo is a project to make small openhardware robots for educational and hobbyist use. We aim to design capable robots which can be assembled without soldering. It’s a modular set of open-hardware components that can be assembled into robots of different...

[T] Tetrinsic Taic: Solar panel variant
Log from Tetrinsic [gd0041]
I was looking at the nice little solar cell built into my calculator, and thought of something: for the people that would say "I'd (almost) never turn those LCDs on", what if a different surface could still have a use compared to a inert slab of material?...

[L] The Magic of QuickRoute Airwire
Log from Tetrinsic [gd0041]
Progress update: Basically, what happened is that I spawned those vias around the BLDC controller to see what kind of space I needed to have for ICs. I extended the PCB 5mm, which gave me loads of room. Looking at the Tetrinsic 3D model, I reduced...

Differences between External Rotor Motor and Internal Rotor Motor
Hacker page by Mark Liu
The rotor is one of the very important parts of the motor ,stepper motor , BLDC motor and sp on. The outer rotor and the inner rotor are two common rotor types in the field of motors. According to the position of the rotor, DC motors can be...

Long time no update... some words on glue...
Log from Entropy Wheel Heat Recovery Ventilator
The clips are definitely the way to go here... I have finally completed the original glued wheel (just the wheel, not the whole prototype) and it's quite the chunk of plastic, 10" cylinder x 14" long, almost two full 4x8ft sheets. The glue is messy (3M...

SmoothControl
Details from SmoothControl
The code for 3 Phase motor control is meant to run on the ATmega32U4 microcontroller, on our open-sourced 3 Phase Driver Board. We're currently testing on the following BLDC motors: Turnigy 480 850kv and Turnigy 480 1320kv, but plan to launch on the...

First Design Pics
Log from Powerful Brushless DC Motor Driver/Controller
5/3/2018 Log #1 Today I present some pictures of some of the driver modules I have come to refer to as PowerPACks. In essence, PAC means Power Application Controller, and I must say this is an Active-Semi Inc's Trade Mark. I call my modules PowerPACks...

Gear box Design
Log from Low Cost 3D printed Robot Tail
Background Autodesk Inventor Parametric Design Cycloidal Gear (from my other project) N_ (number of rollers)= 21 ul number of teeth = number of rollers - 1 E_ (eccentricity) = 1 mm Rr_ (radius of rollers) = 2 mm R_ (radius of Rotor) = 25 mm x(t)...

Introduction
Instructions from DIY Arduino based Quadcopter Drone
Hey, what's up, Guys! Akarsh here from CETech. This is the third and final part of our Arduino-based Drone Series. In the first part, we made a flight controller for our drone using the Arduino Nano and MPU6050 module. In the second part, we made an...

[R] Looking at the start of Plover
Log from Tetrinsic [gd0041]
Right now I'm reading how Plover got started through blog posts written by the project founder and it sounds like her and I are on the same page. I'm still at the 2010 blogs though, when multi-touch touchscreens were talked about as the next...

[E1][L] Tetrinsic Pad
Log from Tetrinsic [gd0041]
[L] = [EM] = Electronic designSo I've found out what I need to do to connect the off-board MAX98357 via I2S and I've got an idea to use the same type of ribbon cable (and pad) as the 1.47" LCD: I've used the GND pins to split the power, I2C and...

[M] Battery fits beautifully
Log from Tetent TimerSpy [gd0136]
I looked around on AliExpress to get an idea of the available batteries and their properties (capacity, discharge and dimensions) and they seem really good. It seems easy to get a reputable 5Ah battery and they all have high discharge currents (>10A...
