Now we’re back in my realm of competency, so let’s get going! The biggest issue I was encountering in this project was that the image would rotate slowly but never remain stable. With this behavior it would have been impossible to display 3D animations,...
I've finally completed the V0.2 PCB design!This version includes :a USB port (USB B, because I hate all of the smaller USB jacks).a headphone jack.a new power switch that switches both power and ground, batteries properly in series.diodes to allow batteries...
Digitally laying out major components of a project in 3D space is something I’ve done for many projects, from my FreeNAS Box, to Luggable PC, to Sawppy the Rover. Doing it again for to figure out a more compact layout for Phoebe’s second...
This update: -Material choices -New set of modules from cube, and exploring L systems. -Working jog and twist components -Continued VR explorations -3D print batch on its way, manually arranged for group print. -Updated files (sld and STL) -Presentations...
We have made substantial progress, transforming our raw materials into a working, moving frame. Images of our progress is available in the gallery. Steering Wheel: We 3D printed a steering wheel to be used with our car. Mounted to the steering...
I would have loved to have all auto-feeders, but that would increase the cost significantly. Especially since I don't have a 3d printer (I realize the Ender 3 is under $200 and could do the job, but one thing at a time). So, I found...
In the last log, I looked at a resistive (Z0) oscilloscope - and spectrum analyzer - probe I had been using for a while. That version used a small metal film through-hole resistor. To see how SMD parts would compare, I built and tested another version...
I've now built the LB-302 prototype, which implements the scissor steering method I described in my last log. It was actually only supposed to be a throw-away draft—I basically had no expectation for it to work on first try. But it turned out to work...
17 July 2019 I haven't been doing much with this project except collecting data from my one and only prototype currently living under the lid of my recycling can. I placed it there in April and was happy it survived its maiden pickup. Since then I have...
Black PCB Mock Up and some issuesI like to visualise a a project with the big picture. I threw together the PCB steps files into "OnShape" which is a freebie 3d CAD package that also does assemblies. Viewing the cube as a "whole" allows me to check the...
Huge thanks to JLCPCB (who sponsor my various projects and videos as well as provide the pcbs). $2 for 10 PCBs (in 48hours)!!!: jlcpcb.com/mSo a quick intro to the main design philosophy for this project. I've seen tons of word clocks using everything...
With the small LED 20x15 matrix I noticed significant power loss when using the easy connectors for the LED strips. I didn't see this problem when I soldered the LED strips, it's a pain but seems like worth the effort. I used a 5v 20amp...
Going to use "Red Oak" stain, don't want anything too dark. Water base Urethane ( don't want the fumes).Here are both sides stained and with 3 coats of urethane The water based urethane worked very well. No smell and it dried quickly....
So, this happened - uECG is again available on Tindie! It may be a couple months behind our original schedule (we aimed for May/June, now it's mid-August), but it's here now! On the way, we made a new device case 3D model (and 3D printed a lot...
Introduction: This log is an update on the exploration on reflective surface in log 3 and a showcase of the very first prototype (Jun. 11 to Jun. 18). We plan to put the LED Matrix on the top and the IR receivers & emitters right below it. For prototype...
