Disk Image This is a zip file, so you need to unzip it. Right now this unzips to a 32 gb file, so you need free disk space and you need a 32 gb (or larger) card. And it appears to only work on the Raspberry Pi 3b _not_ the 3b+ The Wifi is different: […]

Welcome to people who saw the Tasty Tech article in Make Magazine. The article says to come to this site to get the latest disk image. Unfortunately the image I currently have is huge (due to my expanding it to fill the SD Card), and I don’t know how to shrink it, and I should […]

The Maker Faire workshop was a lot of fun, and many lessons were learned! On the plus side, I think that all of the robots went home able to dispense liquids. Yay! I am working on some tweaks, improvements, patches, and bug fixes. I will be uploading a new sdcard image, and instructions to write […]

I am a member of the Chimera Art Space in Sebastopol, California. It is an art and maker space. We have a nice wood shop, a good selection of metal machining and welding equipment, a jewelry shop which is fantastic, and relevant to my interests a 100 watt laser cutter with an almost 4 foot […]

I set up a Hello Drinkbot at a part we had recently. I loaded it with various flavors of Torani syrup and set the shot size to 10 ml. My Grandson Finn took over bartending duties and enjoyed dispensing italian soda’s for people! The peristaltic pumps can’t dispense carbonated liquid, so people would put their […]

I have not been writing updates because all of my free time has been me preparing for Maker Faire. There will be a cocktail robot making workshop at 11am on Sunday. Participants will walk away with a working four pump Hello Drinkbot. I have the laser cutting done for close to 30 bots (the workshop […]
