Today’s hack-a-day project was a pencil-and-paper RPG. Based on feedback from people reading the rules, it’s notably bad and I don’t recommend it. Rules here.

My friend Kragen and I wrote a little bytebeat synth tool. You can mess around and have fun. Demo here, code is on github.

Hack-A-Day is a challenge to try and finish 30 projects in 30 days in November.

Today I tried to write a tool to make a floorplan. You can try it here. As usual the source code is on github.

This was an ambitious project for one day, and I didn’t finish everything I wanted. My original goal was to support

• drawing and erasing rectangles (done)
• adding, editing, deleting, and moving text labels (not done)
• adding, deleting, and moving icons (mostly not done)
• autosave (done)
• undo support (done)
• zoom and pan (not done)
• sharing finished projects (stretch goal, not done)

What I did do was pleasantly high-quality, and I made pretty good progress.

A “silly screensaver”. Demo is here. Source code is on github.

A simple screensaver made in my raytracer. Code is on github.

Try it out here. Code is on github.

I’ve wanted to make a receipt-printer zine for a while. Here’s the next best thing, a digital verson.

I made a small game called Doodlemoji Alchemy, together with my friend Jennifer, as part of Hack-A-Day.

You can play it here.

You combine elements to make something new. Sometimes you get an old element:

Sometimes you discover a new one!

Today’s update is a short one. I ported my raytracer from day 02, to the Nvidia GPU: ha3k-06-raytracer

The visuals are pretty much the same. Incidentally I discovered the striations on the ground disappear if we increase the floating point precision.

Render on the GPU is 30x faster (0.05 fps -> 3 fps). That’s still not very fast.

I didn’t get video working yesterday, or anything else visually new. I will call this one a failure overall, because I have nothing interesting to show off. I learned stuff and made progress though, so it’s not so bad.

Here’s a working video!

Lashed furniture is made using sticks and rope or twine. Today’s project was to make one out of bamboo and brown paracord. The frame is shown–imagine boards or many pieces of bamboo forming a top.

We found this little $5 tool to be incredibly good for cutting bamboo. It’s designed for almost the same thing, cutting metal pipes.

It wasn’t bad for a first try. That said, we decided the top wasn’t flat enough to give a good finish, so the whole thing is going to be burned at the next bonfire.
