Large 7 segment LED display
Foam Board - just like most each of my Light-emitting Diode array projects, I like to use crafting foam board due to the fact base rather than a solderable perf board or PCB. The main basis for this really is cost. A complete sheet of foam board can be seen at many dollar stores or at any art shop.
LEDs - This design utilizes 2 LEDs per part, so 14 per digit plus 2 for the colon (dot). Practically any color can be utilized. More about the choice would be talked about in Step 2 - selecting LEDs.
Black Paint - This isn't necesary, especially if you get black colored foam board, but i love the look of the black background behind the LEDs.
Wire - you'll need at the least a couple of legs, depending upon just how long of prospects you'll need. The wire-gauge the power outlines should be only large enough to deal with a half of an amp max, so 25 gauge or bigger line is great. Some lengths of a much smaller measure is fine to get in touch LEDs together in strings.
Sheer Black Pantyhose - For filtering the screen production (see action 10)
Sharp Pick - I prefer a dental choose, but an ice pick would in addition work; it simply should be thin and sharp.
Hot Glue Gun - Hot Glue works very well to dissipate LED light. It is also a great way to protect and insulate the soldered leads.
