Light-Up Cornhole Boards

Parts and jigs for building a set of smart LED-lit cornhole boards. Parts for the board should be printed in weather-resistant filament, e.g. PETG. The jigs can be printed PLA, PETG as they won't be subjected to weather.

The boards each use a piezo sensor to detect bag hitting the board and a pair of IR LEDs for detecting bag going into the hole and changing the effects in response to those events. The controller firmware is running on an ESP8266 and the boards are powered by a single 10KmAh USB power supply.

Parts:

• Electronics case (bottom and top)
• IR LED sensor mounts for the hole (IR TX + IR RX)
• Cap to protect the Piezo sensor
• Battery clips (2 per board)
• Battery retainer
• Wire clips (2 per board)
• USB cable clip to prevent the USB power cord from dangling when not plugged in
• Front foot bumpers (optional - to prevent bouncing on hard surface - print in flex material)
• Back foot bumpers (print in flex material)

Jigs:

• Hole epoxy dam (also doubles as paint mask for the epoxy around the hole)
• Hole paint marker
• Corner paint marker
• Side paint marker
• Corner Bracket (for holding the box together during glue-up - in lieu of corner clamps)
• Leg Hole Jig (to avoid measuring and to guide the drill straight in)
• Epoxy Form Support Corners (to support 2.5"x1" boards used for assembly of epoxy forms)
• Epoxy Form Brackets (so hold short-ends of epoxy form to the long sides - reduces the need for lot of 4'+ clamps - see photo)
• Leg Round Router Template (makes it easy to route round ends of the legs)
• Header Soldering Stand to make it easy to solder headers to the (upside-down) PCB

A fairly thorough build guide is available in a public Google Document. It includes parts lists, instructions to flash software onto the chips, etc.
