Iris

The Iris keyboard, a split ergonomic keyboard with 4x6 vertically staggered keys and 3 or 4 thumb keys. Time to stop stretching your thumbs out on the Ergodox!

Mini Tank Robot

I’ve been talking to Jules about building a robot with him this year, and tonight I found this neat kit on Aliexpress: less than $100AUD, Arduino-based and with enough complexity for the two of us to have some fun building and programming it.

Deadzone and WH40k Minatures

This is one of those hobbies which those who pursued would have done in their teenage years. Well, I missed out somehow (not willing to embrace my geek nature perhaps?) but it won’t stop me from giving it a go as a forty year-old man.

Agent Bingo Robot

A couple of years ago, Jules got given a cheap toy robot, and it wasn’t long before it broke. He wasn’t too fussed1 and eventually let me tear it to pieces.

Blockchain Ledger UI

This (ongoing) project is to provide a front-end to a blockchain-based ledger for post-trade services including clearing, settlement and asset registration. It consists of a Java-based backend (microservices) and a React frontend, and is deployed to a Kubernetes cluster (PKS).

Openlumify

I worked for a “data discovery and analytics platform” company1 for a couple of years, and got to see first-hand the power of graph-based datastores for analysis, hypothesis-testing and pattern discovery.

Mechanical Keyboards

As the primary user interface for many generations of computer users, the humble keyboard surely deserves its place in the history books as one of the twentieth century’s greatest inventions. From the surface, at least, it appears to be largely unchanged since the electric typewriter of the ’30s, with the layout even older still — a lattice of switches which, when closed, send an appropriate electrical signal to the computing device — and as a frequent, heavy computer user, I should probably have paid more attention.

Clock Radio

Idea: Replace the guts of the (US-voltage) vintage clock radio I have with an Arduino (driving the display) and a radio circuit. Hacks/Ideas Self-dimming clock display e.g. get brighter gradually towards the alarm time Input: existing controls Gut a portable DAB radio (~$50, ebay) and integrate Add a smart bulb (lumen, phillips hue) to my bedside light and make an easy “dawn light” Voice activation/control(!
