Building a keyboard from scratch. Make a Wind Turbine from 55 Gallon Drums. Solid State Tesla Coil. A solid state Tesla coil is one of the kinds of Tesla coils available.
It has several advantages over the more common spark gap tesla coil. They are less louder than conventional Tesla coils, yet they can still achieve a respectable output. They can also be made to play music through its spark, which is a cool effect. Examples of this trick can be seen by searching for musical tesla coil or singing tesla coil. They are also more friendly to nearby electronic apparatus, although caution should still be applied.
In the following instructable, I will show you how to make a solid state Tesla coil, as well as several helpful tips and hints that will come handy during its construction. While fiddling with the antenna, I accidentally burnt both of the Mosfets, so bear in mind this design is far from perfect.

It happens every so often.
No matter how careful I am, no matter how slowly and thoughtfully I work, I find myself bleeding in the workshop from time to time. I understand that once in a while the Project Gods demand blood sacrifices to ensure successful completion of whatever I'm working on. Still, hemorrhaging bodily fluids have a tendency to mar my careful paint jobs if not taken care of in a timely fashion. I do keep a first aid kit in my workshop. It's nice and new and sterile. So far life-threatening injuries have been pretty rare in the workshop.
I'm really hoping I have a chance to come up with something a bit more poetic. So the other day (which was a Wednesday in this case) I was suffering from some time alone with my macabre imagination and decided that I needed my first aid kit to be more visible and readily accessible. But where have I seen such a thing? This is a health pack from HALO. The first thing I did was gather up oodles and gobs of reference images. Emperor 1510. Vintage book travel-tech organizer. As you may have figured out from my My Life Scoop posts, I’m a bit of a nut for tech accessories, especially pocket-sized ones.
I can’t get over how awesomely small our entertainment devices are becoming; it makes traveling with them so much easier. But one issue I keep running into is how to neatly organize everything, especially the power cords and connector cables that accompany my favorite devices. Rather than spend another plane trip rummaging through my catch-all carry-on bag searching for my headphones, bumping my head on the seat in front of me every time, I decided to make a small tech-accessory organizer using elastic ribbon and an old vintage book cover. This project can be sized up or down and customized in many different ways — the best approach is to gather all the tiny tech things you travel with and see how much there is. After that, it’s just a bit of snipping, sewing and gluing, and you’re on your way to a clean, organized carry-on.
Read the full how-to after the jump! Century eggs. Whether you call them century eggs, hundred-year eggs, millennium eggs or whatever, these outlandish ova are a Chinese delicacy dating back centuries to the Ming Dynasty.
The boastful name suggests these eggs take forever to make, this is a misnomer. Century eggs take about 4-5 weeks to make, a few minutes to work up the courage to open, and a few seconds to eat. Traditionally century eggs were made by preserving chicken or duck eggs in a mixture of salt, lime and ash, then wrapping in rice husks for several weeks. During this time the pH of the egg raises transforming the egg, the chemical process breaks down some of the proteins and fats into smaller, more complex flavours. After curing the yolk of the egg turns a dark green and has a creamy consistency, while the white turns amber and is gelatinous.
I chose a more modern method to achieve the same results: a salt and lye pickling solution, and encasing in modelling clay.
