Today I discovered laser cut living hinges. For some reason the first thing I thought upon this discovery was “hmm.. this would make for an awesome chair. this awesome chair shall be called ‘das laser chair’.”
Anyways, if you have never seen or heard of living hinges (specifically the laser cut type) here are some of the links that got me started:
On to das laser chair!
I whipped up this design in SolidWorks. The chair is still in progress; I need to smooth out the lumbar support, add the living hinges, and bolt the bottom legs together to hold everything together.
The living hinges will go where each of the bends are currently located.
As always, make sure to check back soon. I’ll keep you posted with any and all updates. Expect .dxf’s once I have the hinges in so you can make your own!
I have spent some more time in Solidworks working on the Chadway model. I am focusing on anchoring the wheel mounts so they won’t wobble or give in under the pressure of a rider on the platform. Each wheel mount has four braces attached to it plus an anchor point on the side of the platform.
Here are some pictures:
The goals of this version will be to have a direct gear drive from the motors to the wheels and elevating the centers of the wheels above the rider platform.
Here are some features from solidworks drawing so far…
Expect more updates in the near future
If you don’t keep up with sci-fi/fantasy/geek-culture/pop-culture conventions you’ve probably never heard of Dragon*Con, in which case you should immediately go to there website and check it out. If you have heard of Dragon*Con, you are probably aware that it is arguably the largest multimedia (movies, comics, games, etc..)/pop-culture convention on the face of our great planet.
It has been a desire of mine to attend the Con for several years now and never really had the chance until……..
Dru Meyers (the awesome guy who runs the science track at the con) invited me to attend and participate in a number of science track activities!
So, needless to say I accepted his invite and will be attending Dragon*Con as a professional next weekend (the convention is from September 2-5).
In addition to participating on several discussion panels (Evil geniuses for a better tomorrow, hacking 101, and 201), I will be presenting a talk titled “Neighborhood Nukes: DIY Nuclear Fusion Reactors” and demoing my reactor on Saturday night!
It is truly going to be an epic weekend! if you are going to the convention make sure to come find me and if you aren’t, you should definitely consider attending.
In the meantime I will be preparing the reactor for Dragon*Con so check back regularly and see what I’m up to!
As I mentioned in one of my earlier posts yesterday, I have recently had the opportunity to tour both Vogtle and Belfonte nuclear plants. Due to security reasons pictures were a rarity but, fortunately enough, we were able to snap a few at plant Vogtle.

A breif snap of the unit one control room. Notice the almost entire setup is analog.

Two weekends ago Carl Willis (a friend of mine who works as a nuclear physicist at a company that produces piezoelectric neutron sources) flew all the way from New Mexico out to Newnan to stay with me for the weekend. Our span of activities included working on my fusor, modifying my ludlum counter scaler, and touring two nuclear power plants (stay tuned for pictures from that).
Carl was also so kind as to bring along with him a BF3 neutron detection tube and an Edwards KF-50 diffusion pump. After a couple of nights of basic setup and leak checking we were easily able to obtain vacuum pressures suitable for fusion. So fuse we did!……..Until I ran out of deuterium so, for now you’ll have to live with a video about x-rays and some beautiful star pictures.
First off, check out these rays!
Here is a pretty good picture of the chamber. On the right side you can see the new diffusion pump attached to a brass valve that allows me to pretty well control chamber pressure:
Now for some star pictures!
A bit out of focus but, I like the colors.
Soon I’ll be constructing an electrolysis unit so I can begin fusing again, at which point you’ll definitely see more videos, pictures, and information from me.
I have also been working on an magnetron ion source, look out for more on that tomorrow!
