Calibrating the Electronic Speed Controllers
Instructions from DIY Arduino based Quadcopter Drone
In this step, you need to calibrate the ESCs. By calibrating here we mean to say that we are going to inform our ESC of the max and min limit between which it is going to be operated. The Calibration of ESCs is necessary to prevent some problems such...

[E1][T] Force sensor instead of magnets?!
Log from Tetrinsic [gd0041]
Me yesterday: Me on the train back to my university: m1 (me 1): m1: Rememeber how the light ring of the SmartKnob View had an animation based on how hard you pressed the knob? m2: Yeah. m1: And why didn't we go with the first pre-Tetent idea? m2:...

[M] Sculpting a look
Log from Tetrinsic [gd0041]
This is essentially how I imagined this curve would go… ish… it's kinda boxy though. I've also moved the strain guage right to one side so that I have space for some kind of linear slider. I need 33mm and since the total length target is 70mm, I might...

[L] Updated Schematic with New Components
Log from Tetrinsic [gd0041]
So I've spent... oh it's 22:20 now and I started at 1pm... wow it's been over 9 hours? At this very moment, I've created the symbol and 3D CAD for the AAT101:There's a Fusion360 bug where the pads won't generate correctly if the height and width...

[L] Component alignment and solar pads
Log from Tetrinsic [gd0041]
It's been another 90 minutes and I've got some updates. Just like with 3D CAD, I can have more than one symbol in a component. I still have the freedom to put each symbol in an arbitrary location: I've reordered the Tetrinsic masterpad so that VBLDC...

[R][T] 1.56" AMOLED and LCD backlighting
Log from Tetrinsic [gd0041]
Before I stopped researching once and for all, I had a look on Panelook for the largest screen that's less than 18mm wide. I found the TA016XVHM05 which is an SPI AMOLED panel that's 45mm in length (which means that I could have a...

[A] Motor. Is. Missing!!!
Log from Tetrinsic [gd0041]
Have you ever had that time when you're idly thinking and the thought "I should do something about that one thing before a problem arisises?". Well this morning I remember thinking You know, if those motors go OOS (out of stock) like what happened...

Y.A.R.M. Yet Another Router Mill
Details from Y.A.R.M. Yet Another Router Mill
A Libre/Open Office spreadsheet BOM file has been added that lists sources for the required parts totaling around $1500. The main rails are made from 3"x3"x1/4" aluminum angles, with 1/16" aluminum angle used as replaceable wear strips on the corners...

It's officially a computed tomography scanner!
Log from X-Ray CT scanners get new life
Yay! Since the last post: The shutter has been made less crappy using a dedicated BLDC driver for motors with hall effect sensors. It's not set up right still, but the shutter is moving slowly enough to do real exposures of about a second long. So...

Leg Design V2
Log from TOPS
I’ve decided to redesign the leg before designing the full robot in order to address some issues that arose when testing out the V1 leg. Physical Design Changes Got rid of using limit switches for homing.Reduced total screw count and made it so that...

Ark Navigator Fiduciary Pinax
Log from Synesthetic Homunculus
I am working on a pinax to host the AR fiduciary. It needs to light up an spin. It needs to be able to detect magnetic fields and movement. I've been working on this for a long time and many iterations but the current iteration I'm calling the Ark Navigator....

Smart BusBar for a Mock Lunar Rover
Details from Smart BusBar for a Mock Lunar Rover
At the QUT Robotics club (QUTRC) we are dedicated to fostering innovation and providing students with hands-on learning and practical experience in robotics. The Australian Rover Challenge is a prestigious competition that brings together university...

Isolation Monitoring Device
Details from Isolation Monitoring Device
Leakage control is very important in this vehicle, which operates with a nominal 48V BLDC motor. The insulation control on this electronic card is provided by coding it with the STM32F103C8T6 microprocessor. This card, which works with the logic of...

2018: Ridiculous Engineering
Hacker page by Dave
Boring, well-trod preamble A new year is always a time for reflection and for planning new things. The start of 2018 is no exception. 2017 was a pretty rotten year in a lot of ways, though in a lot of others it was a major improvement over 2016....

Test ESC stuff
Hacker page by Christoph
I'm building a BLDC ESC based on EFM8BB2 running BLHeli_SNCP81253 Gate DriverSIZ322DT NFET pairand a DMN2990UDJ fual NFET for level shifting between 3V3 (MCU) and the 5 V gate driver logic Link to current schematic (possible error in MCU to level...
