Hobby Creek Soldering Octopus!

We’re happy to say that we received new octopuses from . They’re extremely nice helping hands with robust, twist-able arms attached to billet stands

The octopus in its natural environment

The best part is they also sent a board holder, which conveniently attaches to the base of the round helping hands.

here are some green things growing at MITERS

mung bean sprouts!

mango trees! they were doing well until we moved them up there (because the mice were nesting in them) and now we keep forgetting to water them :/ they’re… two years old at this point?

oops just kidding, that last one isn’t growing, it’s just drying. it is green though.

HI MITERS!

Lots of stuff has happened!

Yay!

A Honk band came to visit.

We had a meeting!

We went to Maker Faire! Lots of electric vehicles arrived:

It was raining so we set up a tarp.

Also we tried to fly kits but it was too crowded to fly them for long.

Cappie and Sheep made t-shirts. It was possibly their first project at MITERS.

DRSSTC 2

Greetings everyone!

With the semester almost ending, I’m glad that my second DRSS-Tesla Coil is finally done! DRSSTC 2 began almost a year ago with the goal of making my first tesla coil using brick-style IGBTs.


Tesla Coil 2

DRSSTC makes 4 feet of sparks look easy, in MITERS

First Version

The project began when I bought two Toshiba IGBT half-bridge modules on ebay, good for 150A 600V. The original plan was to build a compact and powerful DRSSTC running this full bridge, with about a foot long secondary. The coil also uses a revised version of Steve Ward’s UD2 as the driver. After many months of work, I finally got everything put together. Unfortunately, initial tests were worrying, and I soon found out that one of my IGBTs was half-dead. With the lack of time and money, I wasn’t able to continue with these bricks.

Revision 2

I managed to get hold of a CM200DU-24F 200A 1200V IGBT and decided to make a half-bridge coil instead. The CM200 bricks are larger, so I wasn’t able to fit a fullbridge inside the box I had already made. Finally, this worked perfectly and everything came together.

Specifications:

– CM200 Half Bridge
– 208VAC input (2 leads from 3 Phase, though the coil was designed for 240VAC operation)
– 13″ x 3.5″Secondary, ~2000 turns
– 16″ x 4″ Toroid (I want to get a spun one someday)
