General hardware / Alphapix 16 Dead, Inside voltages are good to the ARm cpu. Unable to ping it

« on: January 19, 2017, 01:16:07 PM »

I have 2 alphapix 16 with blank screen unpingble and no status led. Dave at holidaycoro would not fix them. He want me to buy new boards.
Did you find a fix to yours. I fallow the instructions where you press 3 switches to reload firmware, but no go.
the bottom row of the LCD screen shows very faint squares (all bottom line an with no character definition)
Any help would be appreciated.
Thank you

My Show Setup / Re: Ferris Wheel 7' diameter 500 12mm pix LED rotating using 24v torque motor

I will post pictures next week when I get back home from vacation. I used 2 slip rings rated at 30 amps 3 wire on each slip ring. Slip ring in the front provides power only and slip ring in the back provides data only. I am using pix lite 4 which is mounted in a weather proof box along with 12 volt power supply. I installed vent ports for cooling. I wires spoked starting from the closest point to the shaft up to the outer ring continuing over to the next spoke and down towards the center. I wired 170 pixels per 1 and 2 and output 3 has 160. The 24volts power supply is housed on plastic box, both boxes are mounted rear of the Ferris wheel support frame. Power infection on every 50 pixel. Every connection is soldered painted with lacker and heat shink tubing. I created a custom model as whole Ferris wheel and sub-model for spinners, 16 of them. Center hubs where made by sandwiching 3 3/4 plywood and drilling 16 holes for spokes.

I am using a bodine 24 volt dc low rpm gear box torque motor with a potentiometer as speed control and by removing a jumper I can rotate the opposite direction. I have modified a pixel (chip ws2811) and interfaced it to stop, spin faster slower or backward.motor is rectangular about 4" x 10" long interfaced to a 16 teeth bicycle sprocket
