Build a DIY geiger counter that uses a PIN photodiode as a substitute for an expensive Geiger-Mueller tube. It detects alpha and beta radiation particles. The circuit is soldered onto a small protoboard and everything is placed in an aluminum enclosure. Copper tubing and a piece of aluminum foil is used to help filter out […]

We’ve all heard of the smoke test, and we know that it’s the lowest possible bar for performance of an electronic device. If it doesn’t burst into flames when power is applied, you’re good to go for more functional testing. But the smoke test means something else for cars, especially those powered by diesel fuel.

Every year, over a million people are killed by malaria. The only solution to this problem is to destroy mosquito breeding grounds and curb the problem at source. As mosquitoes breed in stagnant water, I concluded that surface aeration would be one of the best means of eliminating breeding grounds. So I built a device

In one of our previous articles, we built a DIY air quality monitor which was based on measuring the amount of Hydrocarbon concentration in the air using the BME680 VOC Whisker. While things work quite well using that method, there are several other parameters and air constituents which also have the same devastating effect and may be present in the air,
