Lattice BoltzmannLattice Boltzmann methods can be used to simulate fluid flow on a grid of cells. The goal is to parallelize the LB calculation onto the FPGA, but there are a few steps to do first. First figure out the algorithm and tune it in matlab....
Early on I figured I'd need to test some CR2477 cells to see how much energy they could practically supply in a short time. I finally got around to building the tester and putting it to work (not to spoil the surprise, but things don't look great...
A previous search revealed that there were LED modules that were 15mm wide and had 3 digits. We need 3 of those side to side to get the 9 digits a Sinclair Scientific needs. Previous implementations using two packs of 4 bubble LED modules needed...
I'm really frustrated with my air compressor, it is just too darn loud! I have a Stanley Bostitch BTFP02012 6 gallon pancake compressor that is rated at 2.6 SCFM at 90 PSI with a peak pressure of 150 PSI. The claim is that it produces...
Are you also wondering why Cricut Maker Black Friday deals are so early? Well, for your information, capitalism doesn’t simply follow calendar dates. Hence, everyone wants to grab the best offers to buy their desirable products. Personally,...
More of a blog entry than a project one.Sort of a milestone this weekend, we actually spent time making parts for a robot we're trying to get ready before the end of the month. For a short while it was even like a normal CNC shop where we are popping...
I had absolutely no intention of posting this on Hackday. It's a small one-day hack (well, two-day, if you count the time waiting for the epoxy to dry) that piggybacks on all the other blinkylight fun I've had. New code? Nope; I'd already abstracted...
This tutorial uses the Hexabitz modular hardware system to create an all-in-one plant monitoring and watering system. Automate your way to happy plants 😀🪴 Hardware: Load Cell Sensor (H26R0x): H26R0x is a load cell (strain gauge) sensor...
So I've decided on using the Mode 3 (2nd) of the pinouts for RGB565 as seen here https://www.raspberrypi.org/documentation/hardware/raspberrypi/dpi/README.md After a while I've figured out where to solder what cable and also managed to do the device...
Overview This project is to be a 3-part setup for teaching piano for beginners. It is intended to be a way to ease in people who have a desire to learn music, but are unsure if they are willing to fully invest. The original teaching modes are as follows:...
From the late 1800s to the late 1900s, the typewriter was one of the best ways to write documents. Sadly, they were largely rendered obsolete by the rise of home computers. I didn’t grow up using a typewriter, but a couple months ago I bought a Brother...
Audio testing is now complete. This includes both hardware updates and the software to generate the sound. Since the sound system is finalized this would be a good point to review all the gory details. Hardware To keep the hardware minimal, no registers...
INS-1 / ИНC-1 Fortunately, these single dot tubes are still easy to find in large quantity and rather cheap. Made by Gazotron, it seems they buildup a large stock at that time. The INS-1 has the advantage to be small and produce a nice dot due...
***SCOPE*** We want to provide a very cost efficient control unit which is capable of tracking solar panels to the sun with a high precision even with imprecise solar tracker mechanics. In particular it tracks concentrator photovoltaic (CPV) modules...
Ionizing radiation is a nonthermal process utilized to achieve the preservation of food. At a maximum commercial irradiation dose of 10 kGy, irradiation does not impart heat to the food, and the nutritional quality of the food is generally unaffected....
