Anyone into game modding? I'd love a patch that gives all the nazis in Indiana Jones & the Great Circle Elon's face.

Mmm, look at all those Coral TPUs. 4 Dual Edge TPUs, on @MagicBlueSmoke's M.2 Dual edge TPUs adapters, on a PCIE 16x to 4*4x bifurcation adapter.

Yuma @cheynehalloran , I'd love to know more about the cultural significance of Mt Ainslie, and it's Ngunnawal name. May I pick your brain please?

After wrestling with brownout resets on the new pool controller for a week, including swapping DC regs and removing every active component from the board, it now works. The culprit? Crappy 12V transformer based PSU. Replace with a switch mode plugpack and it's happy.

New PCBs for the latest version of my pool controller have arrived! Supports 5 channels of pH & ORP, 4 SSR outputs for heat pumps/pool pumps, temp monitoring, and 4 motors/solenoids for chem dosing. Will monitor and dose both our pool & spa, and report back to HomeAssistant

I started testing my pool controller today - I think these "precision" op-amps I bought to read the PH sensors from Aliexpress are fake *sigh*

Hey @auspost , instead of sending passive aggressive notes like this, why not make things easier for your customers by allowing scheduled payments directly, via Bpay or integrating with banks?

Finished soldering the 70 pins of through hole headers (per board) for 35 orange pi hats for the #lca2019 home automation workshop, 11 hours. Next time round, I'm getting stuff fabbed in China

Woot, fixed some bugs in my 1wire libs, completed an end-to-end test of the prototype hardware, made some minor mods & now the #LCA2019 Home Automation workshop boards are off to fab. Now porting HASS-OS to the Orange Pi Prime

Prototypes for my #LCA2019 home automation workshop. The right board is an orange pi prime, with a custom daughterboard bringing in 24V power, 433MHz RX/TX radio and 1 Wire. The left is a firmware implementation of 1 Wire on an STM32 micro, providing 15 IOs for relays/switches.

So, IBM Ozlabs is hiring. If you're interested in Linux Kernel development, and are in Canberra (or happy to relocate), hit me up.

Ok, thanks, My spindle body is 100mm diameter, and my hose is 100mm nominal, so 96mm-100mm outer diameter for the connection, with a negative taper would do nicely

#TEDxCanberra was thoroughly enjoyable, thanks to the organisers & volunteers. RE Charles Massy's talk: mention of the pseudoscience biodynamics detracts from his message, & the science does not support the claim that glyphosate affects the gut microbiome: bit.ly/2NqnoHF

Sphericons are unique solids that roll in such a way that every point on their surface comes in contact with the plane. Solids from the sphericon family all have one side and two edges. Each sphericon is based on a regular polygon: this is from a hexagon buff.ly/2Mw4gE1
