Hello to my friends (if I have any)
I am starting this thread for my new sale sign I built but I needed it done sooner then time allowed so I haven't put the picaxe chip 20m2 in it yet.(to make it flash all cool)
I router 'd each display and drilled holes in the back for wires the letters are about 8 inches tall each arrow is separate with a switch to choose which way to point
I got the large digital displays off ebay and parts from my garage. I just hooked up the digits with 650 ohm resistors and placed my cheap harbor freight battery to it (only one)
It lights up perfectly in the garage but when you bring out in the sun you can't see shh crap unless you shove you nose to one of the digits so I call it in testing stage. I am planning on getting tinted plexiglass
and holding it out 6 inches from the displays then in theory it should light up beautiful. I tested on one HF garbage battery with presumable 90% charge the sign full lit lasted a staggering 2 hours.
After the sign lights went out I put the battery on the charger again and the power supply that comes with the harbor freight rechargeable drill almost got hot enough to burn my hand.
If by chance there is a person (simple like me) who would want to duplicate this project I highly recommend you do this project 50 feet from any burnable substance, in other words like poeple
have said on here the battery's SUCK! I do have 1 amp schottky diodes for when i try both batterys and I will post more on my sale sign when I add my chip using a buck converter.
It might be awhile because I work a lot but I should be done with it in a couple weeks - 2 months.
I know I know why use those batterys?? well they kinda work and it cost me nothing plus they are light compared to car battery
Plus its entertaining for me because stuff can go wrong.
thanks

PS: I still think 74hc595 ic's are the best and westaust55 code using them is priceless
but nothing comes close to the picaxe 20m2! unless of course your not me
