"If i type 2222, 3333, 3141, 2141, 2888, 3888 etc wherever i put the 3 or the 2 it will show a 0 missing the lower left segment."I am a little lost when you say "it will show a 0 missing" because there is no 0 in the numbers 2222, 3333, 3141, etc....Are you saying that one of the segments are not on?If so which segment? _I _ II _ I
Yeah I agree, 220Ω are fine just brighter i think.
This is simply amazing and joetomel's comment about considering the options of solar power is excellent. Imagine being able to heat an entire building off of oxygen and hydrogen gasses taken from water with solar power. 100% Natural!!

Looking at the schematic it seems as though you are literally creating a short-circuit with a li-po battery. From my RC days I know that it is extremely dangerous to short-out a li-po or any other battery for that matter, in fear for explosion. Because yours has not exploded, and is instead creating energy in the form of heat, what kind of wire are you using?Great InstructableGreat Workshop
thank you so much for these links!!!!
where on earth did you buy your electronics (stepper motors, A4988, and the hardware like the couplers and stuff). Most stepper motors are around $15 a pop and you need at least two so that already uses $30 of the $50/$60 price statement. As for A4988 they are at least $10 and you again need 2 of them resulting in $20 added to the $30 totaling in $50. So you spent $10 dollars on the wood, hardware, arduino, making the pcb, etc?Please share!!!!!!!!!!! Those are some sick deals
