The start of an automatic pet feeder project I'm working on.. The motor mount in this design is for a NEMA17 stepper, but that should be easy to change.

The exit elbow is not finished, needs a little work.

The finished project will be run from a Raspberry Pi with camera to see if cats are feeding...

Update: 2016-01-13 - New exit elbow

All parts are printed and assembled, now time to do the electronics and stepper driver.

My tipping bucket rain gauge design, designed in FreeCAD.

Made for use with an ESP8266 and slotted opto-switch.  All the files are included! The only part that needs supports is the bucket.

Enjoy!

__2020-06-14__ - Added a mounting bracket and filter to the mix!  There was a small update to the bucket too.  The pivot point was too low in the first version.

A quick little case to hold a PSU and ESP8266 (D1 Mini) for monitoring the temperature of the hot water cylinder for my home automation system.

The PSU came from BangGood:

1) A RPi
2) USB/Ethernet hat
3) PoE module
4) SonOff Zigbee USB stick

I'm running zigbee2mqtt..

I've included the FreeCAD model too.

A small project box to house a Wemos D1 Mini and Soil Moisture sensor.  I've added an extra hole for the cable of a DS18B20 temperature probe too.

Power is supplied via some CAT5 cable.  The ESP8266 module is the Wemos D1 Mini V3 PCB, not the one with the ESP8266 in a can in the PCB.

I'm running Tasmota which in turn is sending the value to my MQTT server and on to Home Assistant.

FreeCAD model is included as always!

Enjoy...
