So I finished all the wiring in the lab a while ago and cut out a circular sheet of paper to sit in the front of the arc reactor.





I have all 10 LEDs wired up and powered by 4.5 Volts. There is an 8 Ohm resistor to limit the current flowing into the diodes. The 10 LEDs are wired in parallel to the three AA batteries.



The blue gunk is liquid gasket that I used as an electrical insulator. I hot glued a piece of cardboard to cover it up afterwards.



I also have two quick disconnect terminals from the battery pack and the reactor so I can loop the wires inside of belt hooks and stuff. The battery pack is nice because it is fully enclosed on both ends and has a built-in on/off switch! Radioshack has something good for once!





I then wrapped some lengths of copper conductive wire through the paper and front piece for aesthetics. I did 5 passes for each pair of holes (10 total).



Here she is all lit up.



Here's what it looks like underneath a t-shirt:



And that's it for this one! As for now it's being held up by a crappy strap made of duct tape and a few pieces of tape.

Hey, woohoo for double posts? Anyways, on Thursday night I went out with my friends Jason and Jose and took some really hot photos. Here they are:





The car on the left is the Scion tC which belongs to Jason. The car on the right is the new Lancer Evolution which is Jose's brother's car.





Now the Honda S2000 is Jose's car and the Toyota Corolla is my baby!



I really like the lighting on this one!







Jose had some crazy halogen spotlights that we whipped out and it makes this photo look like DAYTIME! It was insane!











And here we are standing by our respective cars.



Jason decided to sit in the middle of it all.



I caught Jason walking back to us after turning off the lights in the garage.

Well, hope you enjoyed the photos!

Hey, here's my newest project. It's the arc reactor from the new Iron Man movie. I wanted a very thin, lightweight piece that goes on my chest that houses eleven white LEDs that light up underneath a shirt. I have a pack of 100 white LEDs laying around, I figured why not (it was a damned good movie, by the way).

Here is a screenshot from the film itself:



What I started with was a candy container. It was a cardboard cylinder with a metal bottom and a soft plastic cap. It is 4.25 inches in diameter. I then cut the cylinder to a height of 0.5 inches with the metal bottom intact. The metal bottom is very useful because I was able to drill holes into it to mount my LEDs.



As you can see, there are ten LEDs around the outside and one in the center. The LEDs are standard 5mm white LEDs (and can be found dirt cheap on E-bay).



Here I am just playing around with my voltage supply and lighting a few of the LEDs up.



I threw a regular brown T-shirt on top to see what it'd look like:



I was not satisfied with the effect. It just looks like bright dots underneath the shirt. So, I took that plastic top and marked off the pattern on the arc reactor:



Since it is soft plastic (think tupperware or butter containers), I was able to just cut it with an x-acto knife. I then painted it.



I also drilled some holes into it as well, so I can add some details on it with thin gold/copper wire later.

I then put a layer of regular white printer paper underneath this and then threw the same T-shirt on top and came up with this:



Which is a winning effect! I now have to wire up all ten LEDs and find the correct tank top to attach this centerpiece to. It will be powered by three AA batteries and will probably be activated by a pushbutton switch in my pocket. I am going to finish it up at work since I can borrow some resistors and wire from the lab.

So this is LONG past due. I completed the thermal detonator on April 11, 2008 and it was delivered to its rightful owner that night :)

The display stand has been completed April 27, 2008.

Here is a wiring diagram that I designed. It is always good to draw out a diagram when you have many branches!



Here are the guts of the thermal detonator. It is powered by four AA batteries. Notice the black pipe insulation that keeps the battery pack from rattling around. I found that the four AA batteries gives this thing a good amount of weight to it.



Now, without further delay, here is the completed Boushh Thermal Detonator:



The frontal LEDs are actually white, they just showed up blue on the camera.



The display stand is made of a small wood platform (about 5 inches by 5 inches). The edges have been routed. I picked it up at a craft store. The base was sanded and painted black. The plaque was drawn up in photoshop (by me) and printed out on HP Premium Photo Paper and cut to size. It is about 1.5" by 1". It is glued onto an acrylic corner piece which was then glued onto the base itself. The three rods that hold the detonator up itself is 3/8" aluminum that was sanded and polished after being cut to 2" in length.







Here is a video that displays the blinking pattern:



This detonator now belongs to a fierce and beautiful bounty hunter named Julie. :)

Best lap is the last one--especially the final S-Corner! I kicked out the tail end pretty good and had to countersteer at full angle.

So this doesn't really count as the 5th day of the detonator. It's more like the 4.5th day or 4.25th day. I only spent about 30 minutes putting some gold touch on using Rub 'n Buff.

Rub 'n Buff is a metallic finish that is normally used on picture frames to give some metallic life to tarnished edges. It's similar to paint, but it's more of a coating than a paint. You're supposed to use a cloth and "buff" it on, but I find that I like using my hands a lot more than using a cloth. It's important that you only apply minimal amounts, otherwise you will overwhelm the existing paint. I did not want to completely cover the metallic silver that I already had on the piece, but I wanted to accent random areas of the detonator with gold tones. I used Antique Gold and Gold Leaf for this. Again apologies for the low photo quality.

All I need now is clearcoat and electronics! I also wanted to build a display stand, but those parts are still in Fresno and won't be completed up here.

This was actually from Sunday, but I didn't have time to post it until now. I had a lot of problems with the activator switch, so I removed the slide switch and am using a pushbutton SPST instead. This is upsetting since the actual detonator is supposed to be slide-activated and not push-activated, but the pushbutton is going to be a lot more durable. I wasn't able to finish the detonator before I left Fresno, but I got far enough where I can actually finish this thing off out here in Berkeley. I've got a bag full of tools that I need: soldering iron, heatshrink, wiring, solder, resistors, LEDs, hot glue, Rub 'n Buff, Clearcoat (satin), and wire. Not sure when this project will continue, though, because school is back with a vengeance.



Here is the top of the detonator with primer painted on. Notice the changes to the activation switch (this is the pushbutton). Also notice that I weathered the detonator--which is a fancy way of saying that I got a hacksaw, file, and dremel and beat the shit out of it. There are little cut marks and scratches all over.



Here is the bottom half of the detonator with another coat of primer on it. Also notice the weathering.



Here's both halves with primer on it.



Another angle of the same shot.



Here is the detonator with black paint on it. It's still wet, so that's why it looks so glossy.



Different view of the same shot.



Here is a closeup of the top half with black paint on. It's still wet.



Here is the bottom half with black paint on.



After the black paint dried, I put a light coat of metallic silver paint on. Sorry about the terrible lighting--the silver doesn't show up very well in these shots.



That's it for now. I'm actually letting the detonator dry completely before I work gold leaf and antique gold Rub 'n Buff into it. I threw on 4-5 coats of spraypaint all in the span of a few hours, so hopefully it'll cure properly if I just let the thing sit for a while longer.



Here is a photo of the detonator in Berkeley. It's taken from my cell phone so the quality sucks.
