My sister is a Theater Manager at the Patel Conservatory in Tampa, FL. About two weeks ago she texted me and asked if I could make her a prop she needed for an upcoming production. “How keen would you be on making me a mirror for “Beauty and The Beast,” she said. “They want a mirror that lights up and sparkles like the one from the movie.” Even with limited experience just tinkering around, I knew I could do something fairly easily, so I agreed and got to work.
I combined two different circuits (a 555 timer to flash and a RC circuit to fade) and built a wooden frame with acrylic plates for the front and back. The wood and plastic were CNC-milled, then sanded and painted before the electronics were installed and glued into place.
The result was a fairly decent-looking, shiny, light-up hand mirror with a small thumb button on the right side that flashes 16 bright green LEDs when pressed. It all runs off a single 9-volt battery and the back can be unscrewed to replace it should it ever die.
Total build time from start to finish was probably close to 15 hours over the course of one week. The play was Thursday, July 19th and from what I’ve heard, it was a great success. I’ll add pictures from the performance if I get some.
Yeah. Having access to a laser cutter is pretty boss. I’m planning to wear this to the premiere of a certain movie this weekend. Four layers of acrylic; two diffuse, two opaque. 11 LEDs, 11 100 Ohm resistors, some phone cord, some solder, and a 9V battery. There’s no lack of great pages on Instructables about how to make your own.
In addition to the usual hackery and makers working on their electric cars, Bret fired up the forge again last night. Rich turned some horseshoes into hangers, Adam flattened a steel rod, and Royce folded a metal bar.
In preparation for BarCampMilwaukee6 (this weekend!) Royce and I have been mass producing circuit boards for a “learn to solder” class we’ll be holding. The boards are 1.5″x1.5″ square and include a battery, two resistors, traces in the shape of our logo, and two red LEDs for eyes. The copper traces were tinned using “Tin It” to prevent oxidation and make it easier to solder. We’ve made 65 of the “tie pins” so far and the project gave us an opportunity to tweak our methods for PCB etching. We prefer etching with ferric chloride, but muriatic acid and hydrogen peroxide are looking more attractive as they’re cheaper chemicals, can be obtained locally, and etch much faster without heating. Also, red Sharpie markers seem to work really well at cleaning up traces with the muriatic acid solution. Specifically red, not sure why.
A few days ago, I used the Makerspace as a video studio.
A while back, I made an instuctional video on building electric cars, but I have never really done enough promoting of it. I figured a good way to do it is simply to make a pitchman-style YouTube video.
I already had my seamless paper at the Makerspace for our movie night and the band at our opening. So, I set up the paper backdrop and a few of my lights. Instantly, the place went from looking like a metalshop to a video studio.
I WAS filming during the day, so there was a little noise from the neighboring business, but not too bad. It’s much quieter at nigh. There’s also a little echo there. For industrial videos, video blogging, and machine training this is no problem.
Here’s the video that I shot.
Just imagine the giant Makerspace logo right behind me.
September 26-27 at Wisconsin State Fair Park, the same weekend as Harvest Fair. Admission is free. Maker Faire Milwaukee's Call for Makers is now open.
