Playin' around with Electronics and Computers
Anything that relates to 3D printing, mainly projects with 3D printed parts in them.
For a relative that’s paraplegic, I modified the housing of the remote control for the electric wheelchair wheels Alber e-motion M25 to make the usage easier. Mainly, the small housing was made thicker and larger for better handling. Also, one knob was moved to a different position.
The project is not very sophisticated, but I publish it anyhow – perhaps some other handicapped person can benefit from it.

In order to prevent my venetian window blinds to go down on timer in front of my open window-style terrace door, potentially locking me out, I needed to know if the door handle was in the “open” position. However, I did not want to use a battery powered radio sensor, but the existing door open/close magnetic sensor in the door frame. Here’s my solution.

This post is to share my self-made 3D printed housing for a 5V USB voltage converter. Since the used converter board is quite common, I guess others may profit from this design.

The installation of my fuel cell heating required a bi-directional power meter. Bonn Netz, my local power network provider, uses meters of type EasyMeter Q3M which have two infrared interfaces: A bidirectional D0 interface, and a read-only info interface. I use the info interface (INFO-DSS) to read out power consumption and production of the three phases. For this, I built an optical interface, a 3D printed housing for it, and use the UART of a Raspberry Pi with python to get the values.

When I built my media center, it went into a simple black box:
