Honda VTEC Engagement and KMH to MPH Converters

On a lot of Japanese Imports the speedometer has been converted from kilometers per hour to miles per hour for ease of use on British roads. This is done by essentially altering the signal that is sent to the speedometer by a factor of ~0.6 (there are 0.6 miles in a kilometer). The alteration is performed by a little black...

Electronic Delay Latch

The Background A while ago, I built a PC and used an All-in-Wonder Radeon 9700 Pro graphics card. For those who aren’t too familiar with them, read here.

But strangely enough, the more you think about maths or any specific mathematic theory, the more absurd the whole concept becomes. Take for instance the question: “Does 0.9 recurring = 1?” Of course not! I hear you cry, because they are both entirely different...

Fitting a Boost Gauge

On cars fitted with a turbo, the air flowing into the engine for combustion is compressed rather than being allowed to flow in naturally (as in a normally aspirated engine). The advantage is that compression means more air can be forced into the cylinders, and a combined with higher...
