This project really started over a year ago, scratching my own itch. I work as an electronic design engineer and purchasing the parts for my designs seemed to be one of the most tedious tasks. I thought to myself: "That should be fairly easy to automate....
Rabbit ECU project has a new test car! After a 18 months of testing and daily driving the VE Commodore SS L98 engine project, it seemed like a good time to move on to a more high-tech platform. The new test car is a VW GTI Mk6 with EA888 engine. The...

OK, today we are going over all remaining steps needed to get the Raspberry Pi set up to display a simple web page that shows the date and time in the top left corner, and three news feeds right justified in the middle section. I am still working...
For several months now I play with the idea of buying a new computer. My laptop is 8 years old and refuses to die, my rig is 5 and just got a brand new video card. I would need to really justify the investment with something that raises the bar. A truly...
When designing my register file, I kept in mind that I'd want this to be implementable in (mostly) TTL. I wanted to keep programmable logic to a minimum. But I also wanted to have a useful, flexible architecture, which would be...
In this Project, I am building an awesome gaming rig. It is not much different than building a regular PC, but there are few things that you have to keep in mind while choosing the best equipment. Let's build the best Gaming PC Step by Step. Step 1:...
Background: Water is the primary component that makes up about 60 percent of our body weight. When we feel dizzy or have low energy, often times it is because our hydration meter is running low. According to the National Academies of Sciences and Engineering,...
I finally overcame inertia, took advantage of some reasonably nice weather and built up two frames so I could do some testing during the winter season. Testing in summer, at least here in Colorado, is easy. Weather is fine and there is an...
In the southeastern United States, the ring-tone chirping of crickets at night is accompanied by a percussive rattle that's common from mid-summer through fall. Where I live in northwestern Virginia, the dominant percussionist in our nighttime chorus...
Does the world need another 3D-printed prosthetic hand? While the introduction of 3D-printing has led to many new concepts for prosthetic hands, there is still a shortage of products--devices that are actually adopted by end users for regular, long-term...
After printing a few more hexagonal pieces, I quickly learned that joining them with bolts was simply unsustainable. Aside from physical injuries due to pieces snapping when I can't get them positioned just so, I realized that snap-fits are...
An early log talked about 16 possible video modes. This is still the case, but a lot has changed since then. The following should clarify what the current modes are and how they are supported. The 16 modes are defined by 4 bits with the following states:...
This post will meander quite a bit; I got back from my trip safely and have started working on this project again. I also started a new job at a local maker space, one of my job perks is the usage of their space. The access to a shop again is rather...
