LCD 2x20 screen

I’ve got the LCD screen though the post, just in time. Rigged it up tonight, driving it from the RPi 3 using Windows IoT. Worked first time. I ported over my library from .NET Microframework, had to make some changes to accommodate the way the Win IoT stuff works, but happy that it was not too painful!

The display scrolls through a number of messages to the user while it waits for events.


I have a message queue that takes messages to display that other event handlers pump messages to.

Works as  a pattern really well, thus why I’m reusing it for this project. You notice how slow the RPi is compared to the Netduino working with the display. It might however be setting I have wrong.

A bit of a pause while we have visitors for the long weekend,  but enough time to make this fella. As if I needed reminding how soon this project needs to be finished!

Fitting camera

Here is the very cheap camera (only a few quid), screwed to a bit of skirting board. Then fitting it for height in the box. Trying to ensure the focus is good and position is good. This is critical to success, you can’t bodge things like physics and lenses.

Once height is market, I’ll put some more wooden strips along the sides of the box for the camera to rest on.
