I'm working on a molecular sensor. Basically it's a novel sensor (hardware) that uses machine learning techniques (in software) to identify single molecules. I just finished a doctorate were I showed that the technology could compete with mass spec and has applications in high accuracy bio-molecule characterization.

What's the interface like for testing samples? If there is any chance to do it at-range, such a tool would be amazing coupled with a camera and built into an augmented reality system.

Just released my first live-action short film, using a combination of motion capture and conventional shooting.

It's the story of a disgruntled startup founder who summons a demon to take revenge on his co-founders - following a YouTube tutorial...

I'm just in the middle of the publicity for it (film: one of the few venues where it's harder to stand out from the crowd than starting a startup), and after that, it's onto the next film in the series.

Trying to find a way to 3-D print a bubble level for a mouse's skull during surgery. It's tiny as all get out. Hopefully it will help our surgeons practice for better and more repeatable outcomes in our research.

Literal bubble level or just notional? Have you looked into using capacitive liquid levels? There are also MEMS levels that are a smaller, but they're also noisier.

Ha, that would be cool. Unfortunately, to get molecular and sub-molecular resolution on single molecules you have be pretty close to the target (nanometers/Angstroms). You basically load a liquid containing the analyte into the device and push go.

Working on a Bluetooth-enabled, 8 button, one-hand chording keyboard. It appears as a keyboard for typing and a wireless serial port for updating the mappings between chords and keys. Apps for Android and Windows make it easier to update the settings. I'm just planning to use it with my tablet (stuck onto the back) to make typing easier. I also love using it for EagleCAD shortcuts when making PCBs on my Surface (the…

That's very cool. I think I would love to have something like that to go on to the back of a gamepad sort of deal. Working in VR is difficult when you have to change input devices. The gamepad is best for navigation, the keyboard is best for text input, the mouse is overall bad.

Thanks. I agree that handling multiple types of input in VR is difficult. That's actually the problem I wanted to solve with this project when I started it (details: https://hackaday.io/project/1321-keychange). But life intervened and the project scope shrunk.

Maybe one just needs to put it on a drone!

EDIT: I wasn't trying to be snarky. I get excited by certain ideas and was just riffing.

I do some hardware hacking myself sometimes. Been meaning to sew this xbox controller joystick module onto a glove I've built that provides haptic feedback when sensed with the Leap Motion. Hit me up on my profile.

I am working on a habit building app in Meteor. It's really an excuse to get my hands dirty with Meteor, which I am loving.

Found this the other day - might come in handy, if you haven't seen it already. http://themeteorchef.com/

That's really cool. Thanks!
