This is my 3rd post in a series on building a DIY Drop-on-Demand Inkjet Platform. In this post, I am building a camera and lighting rig for capturing moments in the drop formation and jetting sequence. Requirements: The nozzle orifice of a piezo inkjet may be 10s to 100s of microns. While drop diameter will …
This is my second post in a series on building a DIY Drop-on-Demand Inkjet Platform. In my first post, I broke out the components required for the platform. In this post, I’m building the first: An arbitrary waveform generator. This component produces the signal that drives the piezo (good detailed explanation here). When we’re working …
My goal with this project is to build a hobby-grade inkjet platform, from accessible parts, for <$1000, that will enable myself and anyone to experiment with a piezo tube dispenser and different fluids. These types of lab setups are commercially available and commonly used in academia and industry, but prohibitively expensive for most of us …
A few weeks back, I saw a great video from Maker’s Muse on YouTube, describing how to make custom 3×3 puzzles (eg. a Rubik’s cube) out of any 3 dimensional model. I’ve always been curious about how these puzzles work, so what better way to learn than to make my own? Yup. It’s a brain. …
I mentioned in my Digital Gallery Wall post that it would be easy to build a remote control for Meural Canvases. Here it is: This was super easy because each Meural Canvas is wifi-connected and has a tiny webserver. The commands are exposed through a REST interface. So if you know the local IP address …
We make bean-to-bar chocolate in our kitchen and I’m often trying out different ideas to improve our process. The Chocovibe CV100 is a vibration table for molding tempered chocolate. Tempered chocolate has distinctive shine and appealing texture. A temper is achieved by heating and cooling the chocolate to precise points where certain crystal structures form and …
Build process: Modeling. Build process: Silicone molds. Build process: Concrete. Build process: Mounting and framing.
My wife is a serious amateur photographer. A few years ago, we created a photo wall in her office to showcase her framed images. We always intended to swap out the images with new photos over time, but 4 years later, the same images were in these frames… We thought about creating a digital photo …
Idea: My cat has a “bristle-bot” style toy, but it’s not a favorite. He’ll watch it as it wanders randomly around the floor, but he doesn’t really engage with a toy unless it “hides” — goes behind other objects so he can strategize about where it’s going to show up next. The style of motion …
Chocolate making is messy business. One of the steps in nib-to-bar chocolate making is to extract the liquor from the nibs. We use a Champion Juicer. Inevitably, when you add nibs to the chute … a lot of them fly back up the chute and land all over the kitchen. So I built this hopper …
