Finally found time to work on some of my #M5Stack projects.

I2C Servo Unit.

The I2C Servo Unit is almost a clone of M5Stacks official Module but instead of it being a stackable module, the I2C Servo Unit is a plugin unit that connects to the M5Stack I2C port.


The above image is how the official one looks. I have not been able to purchase one and as the circuit and code is open source, I built my own.


Sorry for the bad picture, the human holding the camera wasn’t stable.

I designed this using through hole components as a beginners kits for people wanting to learn how to solder a basic kit. This is the Revision 3 board and unfortunately has some mistakes (the data connector that is on the underside, should be on top!) it works and I’m powering it from two 18650 cells rescued from an old laptop battery.


My next project I have working is Photography turntable. The #M5Stack is used to drive the stepper motor and trigger the camera.

Here I am using a cheep cable remote trigger connected to the M5Stack Relay module. the screw in the trigger is a temp conductive bridge as the first two contacts need to be together in order to fire the Sony SLT A58.

This all was coded using M5Stack UIFlow programming environment and the code is as follows

Yes it is that simple!


My 2011 IX35 didn’t have the reverse camera or dvd head unit. These things are wonderful when there are small cars around. Because I was missing the dvd navigator head unit needed for the cameras display I needed another option.

I ordered this kit for ebay seller Bostrala (recomended by a few Hyundai owners) Reverse camera and monitor

This kit is the easiest way to install a reverse camera. consisting of a camera, transmitter, receiver and monitor for only £32, this is cheep.

Once the kit arrived I set about attacking my car, this turned out to be a simple affair. All I needed for this was

  • Screwdriver (flathead)
  • Crimp tool,
  • Draw Tape
  • Side cutters
  • Knife
  • Insulation Tape,
  • Red crimp ferrels

All I did was pop the tail gate trim pannel, and popped out the existing number plate lights (both sides). I then removed the fitting from the bulb mount and pushed the cable through to the second light before pushing the new module into the slot.

Pull out the rubber gland and cut a slot. push the cameras wiring through the gland and wrap in tape. replace gland and second numberplate light. Now find somewhere to secure the transmitter and wrap in tape. Connect the transmitter and camera together and run the power lead over to the tailgates lights. On the UK model IX35 the drivers side rear/reverse light has 3 wires (Black, yellow and red) the red goes to the reverse light and the yellow to the rear light. Cut and crimp the transmitter to the black and red, tape up the excess wire and check the wiring works by popping the car into reverse (someone will need to look at the transmitter to see if the blue led lights up. Once that works it time for the receiver and monitor. I am intending to get the dvd navigator headunit at some point so only made a temp adapter for the aux socket (ciggy lighter for the smokers)I connected the monitor and transmitter leads together, ran them down between the Headunit and passenger air vent.

Once everything was connected together and working (YAY!) i replaced the tailgate trim and with some effort (you need to push down the trim while pushing it towards the wind screen) put centre console top cover back.

OK call me distracted. While looking for Gunpla parts to 3d print I came across this

Neo Zeon 3D Printed Tripod.

Colour me Impressed, Wish I had the artistic skill for this!
