This is my first post here so I hope it is helps! When you build the Minibrute, if you decide to use Acrylics or Plexiglass, I would check with the manufacturer about its electrical ratings before using it. Yes they do have electrical ratings! When i built mine, i found out that Plexiglass is very bad and is not suggested for use in electrical systems! Acrylic is however, and it is also UL listed for electrical use. Plexiglass holds a very high static charge and can damage sensitive components. Also! The products that are in the Minibrute design book are safe for electrical use (66 nylon etc..) So if you deviate from the book please remember to do the homework!

Welcome on the forum…
I have always thought that Plexiglas (poly methyl metacrylate) and acrylic are synonyms…Please correct me someone. Actually a nice page with information about different plastics and their electrical properties would be quite handy, maybe somebody knows?
I wouldn’t be worried about the static electricity so much. I suppose that for the TC fun you are not using chips with thousands of transistors inside…

Plexiglass actually is acrylic. Acrylic (or actually methyl methacrylate) is the chemical name while Plexiglass is a commercial Trademark name. However, there are various grades of acrylic including static dissipative ones so it is important to check.
Same with polycarbonate and lexan. They are the same thing with Lexan being the commercial Trade Name.

Here is a link that does have some useful information about different plastics and their electrical properties. To eliminate any confusions, when i referred to "Acrylic" and "Plexiglass" I felt they were the most commonly used names. I was not trying to limit the subject to those two alone. I was unaware of the topic until i ordered my plastics and was told by the sales rep. It gets a bit tricky. Thanks to Dr. Gigavolt for always having good information! I am sort of new to coiling so please forgive any of my ignorance. Thankyou Mates for the welcome!

if you want it to be nice looking like the one in your avatar acrilc is the way to go. Lexan or PVC and many others work good to and will hold off many thousands of volts. l prefer PVC because it is cheap and availabil
