Surely he can handle himself with high voltage and dangerous equipment. With this portable x-ray machine, [Grenadier] has begun overloading Geiger counters. We’re just happy he knows what he’s doing. The key component of [...]

For most of us, that means that they can make neat sparks. For the more serious types out there, that also means that they [...]

[Grenadier] has a thing for the high voltage and, as you can see, he’s found multiple ways to build the icon of HV toys - a Jacob’s Ladder. The three look similar, but they use different means of generation the voltages necessary to get a spark to jump through the air. The exhibit on the left uses [...]

Prepare to learn. [Grenadier] has put together a collection of information about AC electricity that can safely be called a super-post. In 62 parts he covers a myriad of topics, some of them safe, many of them not so much. You may want to spend time reading through everything that he has to offer, but just in [...]
