For those without any photo program, here are the transparencies...
So, this took about 30 minutes and 8 bucks. And no complex wiring - cool!
Here's a video. The bicycle light has 6 different settings, this video only shows 1 of them:
Here's what you'll need:
1) printed transparencies from the link below. Do this on any laser printer.
2) Bell Bicycle safety light from WalMart $8 or
3) white paper & scissors
Remove the cover of the Bell safety light. This reduces it to 1/2" thick. Easy for fitting under your vest or armor.
I added a piece of white paper behind the transparencies to help diffuse or evenly disperse the light from the LEDs
Place the transparencies behind the slots in your chest armor
Then attach the Bell light behind your vest (you'll need to cut a hole in your vest) for best result.
Low-budget and easy peasy!
(But obviously Shackman's lights would be the coolest)
What do you think? Any suggestions?
PS. Thanks to feedback from Brak's, I revised the transparencies file so the numbers are spread out a little more to be more accurate. Also, I included a Photoshop file for those without Adobe Illustrator
With all my respect for Shackman and his fantastic chest lights (I wish I had a set of my very own!), this is only a humble attempt at a lowend, do-it-yourself version.
I'm kind of an "accurate from 10 feet away is good enough" kind of guy and I wonder if there's an easier, less expensive way to do chest lights. What if you got several blinking red LEDs (8 or 9) and then printed out one of the displays below on transparency paper? The black would mask the lights and they would just show through the numbers. You may need 2 or 3 layers of transparencies. The LEDs would blink, but because of the black masking, only the letters would appear to blink.
Then you would just make a line of 5 blinking LEDs above for the blinking dashes. The lights could blink at random.
I have a set of LEDs and battery packs that I'm going to try this out with. I have a diagram for wiring he LEDs, but geez I don't know much about that stuff. Here's hoping I don't solder my fingers together!
Here are the display stages. You would pick one for your particular project. Print it on transparency and cut it out.
I'll see if I can round up that wiring diagram.
Do not print this from your browser! Download it to your machine and open it in a photo program (Photoshop, Illustrator, etc) The browser will print it way too big. The photo programs will print them actual size. (300 dpi)
