Forewarning: Bit of a plug for PCBWay in here, but they deserve it. They’re a rad company, and I always like working with them. Premise: This project is a reasonably straightforward keyboard / Bluetooth project, that touches a few neat features, without getting too into the weeds. Really the idea is to do a simple… Read More: T9 »
As with most of my projects lately, I’m finding that I’m playing catch up with the documentation, so this is an old one. This project is a bit of a twofer, because it was the demo project for Stretch, my Kicad plugin. Did I say I have a backlog? Stretch was a pandemic project, initially… Read More: Jet »
This post is about three years late, but I’m catching up. Combat robots like Battlebots are seeing something of a revival right now. The ones on the Battlebots show are 250lbs, and cost tens of thousands of dollars – most of that in batteries. Much more accessibly, there are a bunch of regional competitions,… Read More: 1 Pound Combat Robot »
I’m on a home improvement kick. When I walking my home, there’s a long, featureless hallway with kitchen at the end of it. I was using a tray on my kitchen counter to toss keys onto when I walked in the door. This takes up valuable kitchen counterspace, and being at the end of the… Read More: Key Storage »
Quite some time ago now, I wanted to make some of remote control car. And, also, eventually turn it into an autonomous sumobot or similar. This project was done a few years ago, but I’m writing it up now. In the interest of getting something into my hands that I can iterate on, I did… Read More: The Worst RC Car in the World »
I’ve been wanting to play around with concrete for a while, as a project material. I’m not sure what the end goal will be, but once I’m familiar with the material, I’ll be able to shoehorn it into other projects in unexpected ways. Concrete (actually cement, as I don’t intend to add aggregate) is different… Read More: Rock Planters Rock »
From Wikipedia: Force-directed graph drawing algorithms are a class of algorithms for drawing graphs in an aesthetically-pleasing way. Their purpose is to position the nodes of a graph in two-dimensional or three-dimensional space so that all the edges are of more or less equal length and there are as few crossing edges as possible, by… Read More: Force-Directed Circuit Board Footprint Autoplacement »
I haven’t properly built anything with my hands in a while, so it’s time. I mocked up a few lamp ideas, and this one seemed fun. Really, really rough mock-ups. That was neat looking, so I fleshed out the hinge section, which I expected would be the hardest part to figure out and… Read More: Brass Lamp »
I’ve been into timelapse photograpy for a long time, often focused on driving the cost down by hacking existing digital cameras. That follow up post (already written almost two years after the original work) promised project pictures that were never delivered, so here, I went spelunking in some nearly decade-old backups for them. … Read More: Watching Plants Grow »
This is a fairly old project that I just wanted to document to current-state and provide a conclusion. See here for the old logs. Some of the original design goals for this project were ease of design, and manufacturabilty. Ideally, the design would be clean and turnkey enough for me to be able to… Read More: POV Globe – Electronics »
