DIY High Resolution 3D DLP Printer (3D SLA Printer)
Thanks that is a huge help!
lol "indestructible" if that is a typo or not it definitely fits the bill when describing this instructable. Great job with the tutorial describing the process and the designs are AMAZING. PS im trying to get a delta printer. Can you tell me which of yours you would say is better based on print size, price, and precision / accuracy?
Might be something wrong with your arduino board. You can determine if this is the case my light a single led with the pin on the arduino that lights up the decimal point. Use a simple LED blink sketch and if the LED does not light up that means your arduino is broken. If this is the case you can just change the code and the schematic so that it uses a different pin. If it does work then double check the code. Otherwise I have no idea.
It isn't a problem with the library but it is a problem with the code because when I first got this I had to match the segments to the way that the libraries turned on each segment for each number. So I had to try a whole bunch of variations until I found what I THOUGHT was the right variation. Because you guys are having this problem I am guessing that I found the wrong one. Shouldn't be to hard to fix. I will try to fix it ASAP which might not be until the weekend (school). Thanks for informing me of your problems.
"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
