Make your own neon-style signs without any of the glass, gas, and high voltage! These neon-like LED strips have a great look, are easy to shape and splice, and you can drive them with just 9V to 12V DC.
We'll learn how to control them for blinking and animation using a microcontroller and a Darlington transistor driver.
You can decide how many strips you need depending on the sign you're making. The parts listed below are for the Adabot / Lightning bolt sign I made.
In addition to the parts above, you'll also want a large piece of black foam core board to mount your sign. This will vary depending on size -- I used a 32" x 40" piece for the backboard, and two 20" x 30" pieces for mounting the two sign halves.
You'll use clear zip ties to mount the neon tube strips.
