Changes: decreased thickness PCB from 1.6 to 0.6 mm mirror is placed back into the design (see my blog on optical weakness) increased Bugeja coil size, track length coil increased to 287 mm from 144 mm ...
In the last PCB update post we mentioned that a new version V. 0.5 ( June 2020) of the electrical schematics is in the works. After a few rounds of internal reviews, that new version is now finally ready to be publicly shared.https://gitlab.com/power-progress-community/oshw-powerpc-notebook/powerpc-laptop-mobo...
We've reached a milestone - over 50 days of non-stop work with solar power and 60 simulated trains every day!Yup, rail.X prototype 1.3 attached to a device simulating a railroad barrier is a legit long runner.The version 1.3 is by now working non-stop...
I finally decided to use relays to distribute the power to one selected servo. The path of the power goes through an unbalanced binary tree, made of parallel 8-tree and 4-tree, with a control vector of [1, 2, 4, 4] (total is 11, which is 12-1 as expected).The...
Good things first, the device is ideal for the scenario described in the first log of the project. This device is an ideal choice, when it is necessary to determine which pin of the FPGA is connected to a contact pad reached by Probe Pin on the...
There have been a few updates to the Project: October 2020: The Dice has been tested in a classroom environment with very positive results. The limits set did work with the large classroom and about 25 students, the CO2 levels rose until the Dice...
PCBWay reached out to sponsor this project by providing the next round of prototypes.The newly arrived PCB, logo wasn't required to be put on but I did it anywayA big shoutout to Liam, the whole process was uncomplicated and fast.Speaking of fast, the...
With the charging circuit already designed for the LiFePO4 battery charger, I had to figure out a way to simulate a battery in order to simulate the circuit. A battery is really just a voltage source with some internal resistance, so for the purposes...
My first incarnation of the 'Kubelik' design, using the architecture I set out in the previous post used a single TDA1387 DAC chip. Listening to this, it turned out to have a very engaging improvement in transparency over 'PhiDAC' - there was that sense...
The housing I created for my ACE is basically the housing as used on the ACE 4000 model. This model was was made from injection molded parts, as opposed to the first ACE which was made using vacuum-forming. The difference is clear. The edges are smoother,...
I completely changed my mind for the electronics layout for V2 of the upright laser harp. Initially, I was a little disappointed, because I put a lot of time into brainstorming and designing PCBs for each layer of the laser harp. It was only when I reached...
PCBWay reached out to me through hackaday, and they offered to sponsor my PCB's for my project! In return they wanted a few words on the quality and service they offer. PCBWay even sponsored the delivery costs which was really awesome. Making projects...
Good news - we made our pitch to the game company and they have decided to fund the project. We no longer have to hand assemble code, we now have a fancy Intel MDS-800 development system. And no more wire wrapping - we have a professional...
07/30/17 Technically, this is SensorTile3 since I changed the original Sensor Tile by replacing the switch and substituting the BMA280 for the MPU6500. But since it was this modified Sensor Tile that was used for initial testing, gathering the first...
For some reason, my valve never worked. I disassembled it and found it would only close, but not open anymore. I found a blown trace on the PCB which I repaired, but it's still short-circuited somewhere. I believe either the reverse-voltage protection...
