I came up with this idea after seeing similar videos on the internet. I however have improved on the design. What separates my glasses from the others out there, is that mine use an external matrix driver and battery. What this means is, for the cost of having a cable down your back when wearing the device, you get a greatly improved battery life. This also allows the device to use ultra-bright 1210 LED's. Not only that, a full sized arduino can be used if you have one. This project uses cheap and easy to gain parts to allow you to create a one of a kind fancy dress party piece. These glasses do not obstruct your vision any more than the original shutter shades. Even with the glasses on turned on, no glare from the LEDs can be seen.
For me the most important thing about making these glasses has been, increasing my knowledge and attaining new skills. Here are some of the things I have learnt.
• Solder Surface mounted LEDs.
• Write my own C program and optimize it to store more visual effects.
• Using data arrays to store patterns and frames.
• Create an algorithm to shift out the data from a 3D array.
• Correctly control the chips of the driver circuit.
• Cascade shift registers.
• Use Microsoft Excel to my advantage to create many shortcuts whilst programming the on-screen visuals.
• Efficiently place components on vero board.
Step 1: Parts Bin:
- 200 pcs 1210 SMD LEDs, blue ones can be found here
- 1 pcs Black shutter shades, use these as I have provided a template for use with these glasses.
