Matterport + WebVR DevOps
Log from Metaverse Lab
Matterport is a camera that can automate the process of high resolution reality capturing. The Matterport is reasonably priced with the 3D cameras costing $4500 and a monthly/yearly cloud processing fee. I think that the speed and quality of the system...

Initial LED Selection
Log from E-Bike Light
When I set about this project the first thing I wanted to work out was what LED I was going to use, as this would drive the requirements of everything else in the project, driver, lens, heatsinking, etc. Due to personal preference I decided that I wanted...

Firmware hacking
Log from Model S BMS hacking
Here is a rough schematic of the isolated bus circuitry. It looks like there is some shared "open collector" style bus on CH4 of the isolator, with D8 and (I assume) a pullup on the BMS controller board. But so far I've only ever measured this line being...

HelloPenguin Current Test
Log from HelloPenguin
Running binRed test pattern firmware with new CR2032 battery with UNI-T UT61E meter in series set to Amps and logging over USB link to UT61E.exe. We see a high of 73 mA. Graph of Amps per Sample made in Libre Office No Time DC/AC Value Unit AUTO 1 13:33:16...

2020-08-04 Progress update - SFC/SNES support
Log from BlueRetro
Finished basic SNES 2P support and some experimental 5P Super Multitap support. Multitap can be configured by setting multitap config to Slot 2 in the Web Bluetooth interface. I also fixed a config corruption bug that impacted mostly PS3 & PS4 controllers....

[E1][R][X] AirBerries: Learning a custom keyboard layout
Log from Tetent [gd0090]
So I've recently got a fully electrically and mechanically complete CAD model of Tetrinsic and was, once again, doing some research for Tetent, mainly because I don't like how this featureless flat face looks: It turns out that the eteeController...

Using a Counter for the ISR
Log from Simple Concurrent Tones for the Arduino
Using a counter for the ISRI received a suggestion to use a counter and trip method for the Interrupt Service Routine (ISR). While is was not keen as the method (Direct Digital Synthesis) is pretty standard and gives the best long term accuracy. But...

Receiver Audio Circuit
Log from BARC 20m QRP Transceiver
I started working through the receiver audio circuitry. I spec'd out what I think is a reasonable circuit but it might require some tweaking once the receiver is built, especially the equalizer points. I've had quite a bit of experience designing...

Nonlinear response to improve usability
Log from Stingray
I should apply a gamma curve to the analog axes read from Classic controller to make the response of the stick more subtle near the center and more steep close to the edges. Classic controller analog sticks provide position information with...

Live demonstration prototype at Splash Adelaide 2017 Winter
Log from Cosmic Array
The aim of this project is to deploy 16 individual cosmic ray detectors on the Elder Park foreshore in Adelaide. This is a part of the Splash Adelaide 2017 Winter Festival and is built in collaboration with a group of artist-musicians called Sacred Resonance.Proposed...

Pulser-sequencer
Log from Clockwork germanium
Remember the last logs : the goal is to use as few transistors as possible to send a string of consecutive non-overlapping pulses to several pass-gates. Here the design uses NPN as primary type but it will be reversed later because PNP are the majority...

Power supply, zero crossing detector and triac switch
Log from IR Light Dimmer v2
Here is a very simple capacitive power supply circuit, with triac connected across its terminals. Triac will be triggered with negative impulse.References for power supply and triac control: http://www.st.com/content/ccc/resource/technical/document/application_note/a8/00/35/e2/62/e5/4c/14/CD00266635.pdf/files/CD00266635.pdf/jcr:content/translations/en.CD00266635.pdfAnd...

Deduction of the Linear FCDT volume formula
Log from A new high accuracy tilt sensor
In a previous log (https://hackaday.io/project/11225-a-new-high-accuracy-tilt-sensor/log/46957-theoretical-background-of-the-linear-fcdt) I showed that in case oftilt degrees, the volume of ferrofluid found in the (left) secondary coil is:And in case...

Coding a Solution
Log from Fitting a Quadratic Bezier Curve to Point Data
Mapping Digitised Points to a Trial Quadratic Bezier Curve While the quadratic Bezier curve equation is quite simple, it evaded me how to convert a digitised point to the Bezier curve parameter "t". Upon research I came upon a paper by Nouri A....

Forward Kinematics
Log from Thor
Today I'll share Thor's Forward Kinematics calculus. Forward kinematics allows to compute the position of the end-effector from specified values for the joint parameters. In order to resolve the Forward Kinematics I have used the Denavit-Hartenberg parameters....
