Brew Bubbles Controller Bracket

thingiverse

This bracket supports the Brew Bubbles project. The bracket is designed to position the Wemos D1 Mini and shield with photo-interrupter so that bubbles in the airlock will register and be counted correctly. The hole may need to be adjusted larger or drilled out based on the size of your airlock. If it's too loose around the airlock, a drill stop or even tape can be used on the down-tube under the bracket to hold it firmly in place. There is a hole on the side intended for using a pop-rivet or small screw to secure the temperature sensor cable(s) with an R-type cable clamp. This is recommended to avoid straining the small wires. Uploaded Version 2: - The hole has been enlarged, which was previously only allowing a smaller stem. - Three different ways are now available to secure the bracket to the airlock securely. - A small hole for an optional M3 set screw has been added. - A collar is included to secure a zip-tie around the bracket and stem. - "Ears" have been added allowing for a rubber-band to wrap the device.
