This article is about is packaging a microcontroller project, and why it’s such a struggle to get something that looks halfway presentable. You can buy cheap, well-made PCBs and components from a multitude of sources, but when it comes to putting it all into a box (or on a panel, or wherever), things can get ugly. Literally. Even if the project does turn out nicely, there’s a lot of work involved getting it there. There has to be a better way.

The Arduino ESR project is moving along, albeit a little slowly. The miniature OLED displays finally showed up, and I have to admit, I really like them. A lot. I’ve come up with a concept that will use the small OLED as a dynamic menu, with corresponding pushbuttons to move and select options.

I’ve been buying stuff from China for a long time, and for a long time it was a pleasant experience. Sure, the items purchased might take a while to arrive, but they always arrived. I was never disappointed or surprised. But lately things seem to have changed.

In case anyone is wondering, the ESR project isn’t dead, I’m just waiting for some small OLED displays to show up. I ordered these a while back (in December), and they have yet to arrive. The plan is to use some of the empty space on the front panel next to the display already slated to go there. Here’s what it looks like:
It has a 128 x 32 display space with an I2C interface. You can find this OLED display on eBay, and they go for around $4 each.
It was originally slated to arrive by the 3rd of January, and the tracking info says it’s supposed to show up today, so we’ll see.

A while back I bought an Neje DK-8-KZ 1W laser engraver. It was on sale, and I was curious about it. At only 1W (1000 mW) I knew I wasn’t going to be cutting anything except paper with it, but I was looking for another way to create engraved labeling on plastic enclosures. Well, it can do that, with some limitations, and it works pretty well on wood, but my biggest aggravation has been just getting it to actually put the engraving where I want it to go, and also deal with the automatic scaling it employs.

Here are some images of the CHIP test setup I cobbled together. It’s not pretty, but that’s not important for right now. It works, and it demonstrates one way to assemble things and get a working single-board Linux system up and running. Continue reading ‘C.H.I.P: The VGA test setup’
