Light up Cornhole

To make the game little more fun, and to experiment with the Arduino microprocessor, I added some sound and lights to one of my boards...
I added 20 blue LEDs around the rim and I pulled a dinosaur sound chip and speaker out of a children's toy. An infrared emitter / detector pair mounted across the underside of the hole acts as the trigger. I programmed the Arduino to detect the change in IR level caused by the bean bag passing between the emitter and detector. It then sets off one of 3 light patterns and triggers the sound effect from the dinosaur toy parts.


Update: This has broken and I have not put the effort into fixing it yet. I foolishly mounted the Arduino under the board about 5" in front of the hole. Exactly where many people aim when throwing the 1lb bean bag. I think a solder joint or something on the board itself has failed due to the repeated impact.
Another failure point was the mounting of the IR LED. I installed some short wooden risers to avoid a hanging bag from triggering the effects and mounted the IR pair to the top of the blocks. These wooden block has since cracked along the wood grain and are only hanging on by the LED wires.
When I get around to version 2 there will be a lot of changes....

Kayak cart from a treadmill

Image
I recovered a treadmill that thrown out alongside I-40 and decided to bring it home. I wanted to build a cart to hold my 2 kayak that would roll up underneath my porch and be ease to pull back out again and this looked like a great source of tube steel. I started by cutting it up with an angle grinder and finding the pieces I wanted to use. Having never welded anything before, I started with a 220V 50amp stick welder I borrowed from my neighbor. I quickly found that it couldn't be set it low enough to keep from burning right through the thin metal. So I convinced myself that I could afford to buy a small MIG welder. I bought a Hobart Handler 140 from Tractor Supply. Its a 115V welder and can work on much thinner material. The handle and pull bar attached to the front (left of picture below) were also found along side I40. As was the pipe I have at the top separating the 2 vertical posts. I re-purposed the treadmill arm pads and rubber tread-guides to cushion the kayaks against the

Forged Sea Turtle hinges

Image
My first forging project, a pair of hinges shaped like sea turtles for my deck gate. Not perfect, but I was very happy with the result. And as a bonus, they actually work as hinges! They've been installed on my gate for a couple months now, they work well and look good.

Cube Twist Fireplace Set

Image
"...awesome and cooler than any I've ever seen..." - The client A client commissioned a set of fireplace tools, after discussing a couple of options they settled on the cube twist as the primary design element. This is the finished product: The Handles I added a slight variation to the cube twists I've regularly seen. I didn't like the look of the ridge between the cubes and the flat, so I made a couple of chisels / flatters to open up the longitudinal groove and flatten it out. This creates a softer look and helps to visually isolate the cubes. Below is is a video (I like this guy, and he does some really good work) on how to make the twist. The photo is the test piece I made, you can see how the ridge between the corners or the bar and the cubes affects the appearance. Harder to see in the photo is that I experimented with taking the corners off the cubes to create semi-pyramid shapes. I didn't like that look for his, but maybe for a future p
