Connecting a Cisco 8831 to Asterisk
Derry Hamilton - 03/11/2023
Cisco VOIP phones have the benefit that their advertised features usually work. At least minimally, once you've figured out the right incantation, and how to sidestep the broken bits. Which is more than can be said for most of their competition (stares hard at Avaya). The downside is that...
Microtik RB750gr3 vs. OpenWRT extroot
Derry Hamilton - 13/10/2023
The Microtik RB750gr3 is a very nice router for the money, and plays nicely with OpenWRT, too. However, it comes with very little flash, so it needs an extroot on a MicroSD card. Unfortunately, the stock OpenWRT 22 appears very picky about the card it will work with. ext4_check_descriptors:...

An Antenna Bracket
Derry Hamilton - 02/02/2015
I was looking for an antenna bracket that would fix to a camera tripod, and allow vertical antennas on 2m/70cm, and a pair of HF whips horizontally. No such thing appeared to exist, so I designed one. The easiest way appeared to be to use Schaeffer‘s Front Panel Designer. It...

Popped up Ben Chonzie while Tor was investigating Yarn. Visibility was poor, but good for navigation practice. ...
Polldubh climbing
Derry Hamilton - 18/10/2013
Tor and I headed to Fort William for half term, intending to do some climbing, some walking, and some touristing. Tuesday saw us climbing at Polldubh. Looking for an appropriate climb, Alan had been talking about "The Gutter" and that seemed like a good place to start. A nice easy lead, good belays, and...
Dumby
Derry Hamilton - 28/09/2013
I was at a loose end, so I took a trip to Dumbarton. It's good, and very convenient by train. It would be more useful if either it and I were at the same side of the country. It's hard. Much harder than I am; there's only about a dozen named problems I...
Bennybeg
Derry Hamilton - 02/06/2013
A few people were after a rock climbing, picnicing sort of a day, so we headed to Bennybeg; easy sport climbing in a nice setting. Since this was the first time on real rock for a few people, we figured sport climbing was a better bet, since it was most like indoor climbing. Tor,...
Ben Nevis on New Year's Day
Derry Hamilton - 01/01/2013
Trying to climb Ben Nevis on the first appears to be becoming a tradition. Not that we always succeed. This year, we found some (almost friendly) ptarmigan in their winter plumage. ...
A day on the grit.
Derry Hamilton - 23/03/2012
The first photo is of our objective for the day, Valkyrie, at The Roaches. Looking forward and back. These are taken at the top of pitch 1, stood on the V shaped block in the top right of the first photo. Both our photos make it look like a quick scramble, but Tor's about to head...
Going all traditional again.
Derry Hamilton - 11/02/2012
Tor and I had intended that this winter would be one of ice climbing, but an unusually warm winter and difficulty getting up north means that the first outdoor event of the winter season was rock climbing at Blackford Quarry, in february! (Still warmer than Ratho untill the sun went down!) The cracks on...
TCA Glasgow
Derry Hamilton - 28/01/2012
Several of us decided to take a look at TCA Glasgow, the new bouldering place. The original TCA in bristol is well regarded, and the Glasgow one is getting off to a strong start and has the potential to be the best indoor bouldering venue in Scotland. There's loads of well used space, and...
Blown off The Ben
Derry Hamilton - 31/12/2011
T and I had headed up to Fort William with the intention of doing the CMD arete, but in the end, the weather proved unsuitable for anything as Grandson-of-Bawbag was trying to take down even more trees and remove all the snow. So we headed to The Ice Factor for some indoor snow. I was somewhat...
Some cat photos.

I decided to try out the black screen with Tim, our black and while cat. ...
