I remember playing with my Lite Brite when I was young. What looks better than sticking solid plastic pegs into fixed holes in a grid of plastic? The answer is the beautiful glow of individual LEDs soldered into a perf board! There is of course some added complexity that comes with that choice. These days I am answering lots of questions on LED applications from our LED customers, what resistance should be used, what voltage should be used, what is the ideal current for a certain application, what series parallel combination should be used, etc. A LED resistor calculator helps but is still not super simple for all end users. That’s what makes these Hi-Tec Sketch Art products shine! All you do is pick up an LED with the desired color and stick it in the special pad. Keep sticking LEDs in the pad until your design is done. 

The model pictured above is the Hi-Tec Sketch Art model.
