Infrastructure Updates

For the last while, the website’s been running on caddy. Caddy’s a really nice piece of software - https integrated as standard with let’s encrypt, http2 support by default and a simple config file format. It’s pretty cool, I really like it. Unfortunately it’s not yet in any repos, and I don’t feel particularly secure running a server by starting it with sudo and keeping the files and configs in my home directory.

Hackbook FreeBSD - Wifi

My notebook for this evening’s work states “This fucking computer is insanity”. I’ve clearly picked up the term from tj. I’ve spent a lot of time fucking about with this wifi nonsense. Here’s the compressed overview of how far I’ve got: I’m loading every module related to ipw and wlan under the sun in /boot/loader.conf: if_ipw_load="YES" legal.intel_ipw.license_ack=1 ipw_bss_load="YES" ipw_ibss_load="YES" wlan_scan_ap_load="YES" wlan_scan_sta_load="YES" wlan_wep_load="YES" wlan_ccmp_load="YES" wlan_tkip_load="YES" No idea what half that wlan stuff does, maybe I should read up some…

Preparing for 33c3

Ugh, I’ve been meaning to blog for a while. Little projects to write up for future hibby. I’ve been so tired lately I’ve been forgetting, so I’ve tried to get into the habit of writing in my notepad what I’ve been doing at the close of play. It’s been quite productive - that’s where the last few blogs have come from and the RSGB convention writeups came from. 33C3 is nearly upon us and I’ve been horrifically disorganised for it.

ESP8266 First Steps

So, I’ve been slowly working on the lights in the hackerspace. I’ve rewired them using Weidmuller WDU2.5 terminals on DIN rail, as this is what I use in work. It’s a pretty great system and lets me have clean wiring, easy to read wiring and things will probably be safer. The next steps I’d like to take are to implement the Internet of Shit on our LED lamps above the main workspaces.

DATV - Step 2

This is a continuation of this post about my previous failures at DATV. Debug, Defrag, Defuzz and Start Again Okay, so Bournemouth didn’t go so well. Let’s try again - this time reading manuals and stopping to think. The goal for this project is simple - transmit and receive a DVB-S signal. Hardware What tools do I have available? CCC Camp Badge (HackRF) RTL-SDR Numerous Raspberry Pis Laptop (Linux) Probably a whole other pile of things

FreeBSD - RTFM

So I’ve been curious about running more FreeBSD for a while, it’s kind of an interesting OS. I’ve been dipping my toes in the water by managing to install it on my hackbook (HP Compaq TC1100) with the intention of taking it to 32C3 as my main device. FreeBSD has some lovely architecture features that I really enjoy - the base system is more or less an immutable image between installs, bar a few files… At least it is in my use case.

DATV - Step 1

Digital Amateur Television After the RSGB Convention’s DATV talk, I’ve been super curious about playing more with DATV (Digital Amateur TV). It’s pretty cool - transmit broadcast standard video using low powers and homebrewe equipment. I remember many moons ago Iain, tj and I came up with an MPEG4 proof of concept and streamed Citizenfour between a hackrf and rtl-sdr. Naturally, to do it properly, I’m going to have to advance my license (work in progress, honest).

2016 RSGB Convention Day 2

See Day 1 notes for the first half of this piece! Convention’s over! I left Milton Keynes at roughly 1630 after a full day of lectures and after a stopoff in Glasgow made it home at 3am. Total round trip of 1003 miles! That’s a long way to go for some radio chat. Day 2 was again insteresting, enthusing and inspiring - here’s a compressed colletion of the notes I took.

2016 RSGB Convention Day 1

So, I came down to the RSGB Convention to see what’s what in the world of radio. After day 1, it’s been good - Here’s a disorganised selection of my notes and thoughts. Session 1: Advances in Amateur TV Given by Noel Matthews, G8GTZ Noel started out telling us about the bands that ATV is on these days, the ones that caught my interest were: 13CM (Roughly 2432MHz) 70CM (2MHz, Digital centered around 437MHz) 2M 2M D-ATV 2M Digital Amateur TV is really interesting, it seems.

Android for Desert 2

Abroad’s going mostly well. Initially very busy, now things have slowed down and I’m waiting on others. I’ve been fiddling with this tablet a lot. It’s been, much to my surprise, really useful. A Tablet in Industry As I said previously I really like the size and shape of it. I’ve been using it in my industrial context extensively as a document viewer. 16GB is a large amount of documentation, and having it in the palm of my hand (or pocket) at all times is super useful.
