It’s time for me to get my application in for the 2016 San Mateo Maker Faire. I’ve participated in a few previous Faires and this year I thought I’d add something to my usual offering of cookie tin ukuleles and other instruments. If all goes as planned (and they like my proposal) I’ll be at the Faire in May with a peddler’s cart that will transport several instruments and provide a little treadle powered down beat.
In the video I demonstrate my first two crude cam sets that play a waltz and a shuffle. I hope to fit up four sets to knock out a variety of beats. So far this is like playing along with a bad drummer, but I’m getting better at it. The cart rolls nicely on the two wheels like a garden wheel barrow, and when it is tipped up on end (as seen in the video) it will display my instruments and offer its wonky rhythm. The wheels, bearings, and sprockets were scavenged from a kids bike a neighbor was about to chuck in the trash. Some of the wood box is left over molding from a frame shop and the shafts are from my lifetime collection of dumpster gold.
There are many improvements and tweaks in the works; including fitting up the inside of the cart to secure the instruments for travel, painting the exterior, improving the cam sets, and adding more mass to the fly wheel. Stay tuned, there’s more to come.
