"Lights Out" with a keyboard

munger: Scan-to-cloud for local scanners - 31 Jan 2020 Cloud  Hardware  Python 

Despite the ongoing good work in many places to move to fully digital options, many organisations remain committed to sending you shards of dead tree through the post (particularly the NHS, though I can understand that given how they’ve been burnt in the past). Keeping track of all this paper is tricky, and particularly hard…

How to actually secure IoT devices - 30 May 2017 Business Ideas  Hardware  Pontification  Rant 

Every day it feels like there’s some new Internet of Things (IoT) story, telling us how these new devices in our homes and offices are causing more and more havoc. On the other hand, we really like the new and shiny things doing funky things for us, and that doesn’t look like it’s slowing down…

Using the BBC micro:bit with PlatformIO - 28 Aug 2016 C  Hardware  Programming  Tools 

I recently acquired a micro:bit, the new BBC device intended for helping computer education. After a bit of delay, they’ve finally starting shipping the device, and now members of the public like myself can grab one. So, why this device in the middle of a sea of other options in the modern embedded environment? Well,…

Waveform Necklace as a Service - 6 Sep 2015 Hardware  Python  Tools 

I’m generally quite fond of laser cutters and cute crafting things done with them, so when I saw a Waveform Necklace Instructable the other day, I had to give it a go. Basic idea is that you take a sound recording’s waveform and reduce it’s waveform down to a level where it can be reasonably represented…

Spark Core-based proxy - 10 Aug 2015 C  Hardware  Python 

Regular readers of this blog will have seen my earlier post on Dalek remote control where I used a Spark Core to connect the Dalek’s remote control to the internet. However, in the second post I noted how hotel Wi-Fi is basically evil, and so I ran into all manner of problems with connecting the Spark to the Wi-Fi in…

Telepresence Dalek: Part 2 – Video - 25 Jun 2015 Convention  Hardware  Javascript 

Previously I wrote about the remote control parts of the Telepresence Dalek, but that’s only half the problem. The other half is video, both to provide a view of the Dalek’s PoV for the operator and to display the operator’s face on the Dalek. I’d been thinking about this problem for several months before actually getting…

Telepresence Dalek: Part 1 – Remote control - 18 Apr 2015 Convention  Hardware  Howto  Javascript  Python 

Earlier this month, I went to a science-fiction convention by the name of Dysprosium. At said convention was a competition called “Dalekdrome”, with the idea of taking remote controlled Daleks and then customising them. When I was first told about this, I was at another convention where someone was attending via a telepresence robot, and so…
