Audio

I’m not really an audiophile, but I do like to listen to music. Inspired by my nephew I started to build my audio setup again.

Music

I like quite a diverse palet of music. You can view my music collection here.

Thinkpad T440s keyboard backlight

A while back I made a simple python script to get the keyboard backlight of the laptop to dynamically switch on and off. Normally you control the backlight with a key combination. But I prefer to only have backlight when I’m typing.

Wifi christmas tree coding

Since the last posting I connected the christmas tree to an esp8266. I used a Wemos D1 mini for this, which is a very nice and complete board to develop with.

Wifi christmastree

While browsing through the Kwantum folder, I found an intresting, small and cheap christmastree.

It consists of 10 leds, powered by 2 AA batteries. No thrills or whistles. So I decided to buy one and see if I could mod it a little.

Chassis schade (Dutch)

Schade

Aan de bijrijder kant van het chasis zit een scheur in het verticale deel van het aluminium profiel. Dit punt bevat het linker oog van het linker scharnier punt van de bovenste draagarm van de ophanging.

C1 exhaust

Final write up of my 2013 attempt at upgrading the exhaust of my C1.

Speedster rotrex

Decided to finish up writing on the Rotrex installation on the Speedster. Have had some requests about how the setup was done. Some links below.

• Rotrex supercharger installation
• Rotrex ECU calibration

Speedster update

Finally got around to updating some of the content on the Speedster projects.
I finished writing the following pieces:

• 3" Exhaust installation
• 3" Exhaust ECU calibration

Proxmox 4.1 lxcfs

Since Proxmox 4.1 I’ve had a number of issue’s on my servers.

The first (and smallest) issue has to do with my Thinlinc installations. The agent component can hang after running a specific cronjob. A “ps” process starts to hang. The only way to resolv this is to restart the zone. This behaviour seems to be related to the lxcfs package on version 0.13-pve3. Later versions seem to resolve this.

Intake temperature

When converting to the Rotrex supercharger, the intake air temperature sensor remained in the factory location, just after the airfilter. This isn't a huge problem, as the Rotrex setup has quite good cooling. But in order to be safe it would be better to measure the temperature just before it enters the throttlebody.

Happy newyear!

Happy new year! First thing I did is finished a short writeup on the Battery Brain in the Speedster :)

Battery brain

Most people who have a Speedster know that when you leave it standing for a while, the battery drains pretty quickly. I often forget to disconnect the battery. Or, when I do remember it usually turns out that I want to drive it shortly afterwards.

Proxmox 4 migration issues

With the introduction of Proxmox 4 a rather large change was introduced. The combination of KVM and OpenVZ was changed to KVM and LXC. The big upside of this is a recent kernel, changing up from 2.6.36 (released 2010) to 4.2 (currently).

Thinlinc reverse proxy

I ran into this program a while ago when I wanted to run the HTML5 ThinLinc client behind a reverse proxy. The HTML5 client has a number of references in it (and a redirect) that refers to the root of the webserver. So serving the client from a url like

Veeam Jaguar fix

The other day there arrived a package for me at work from Veeam. Having ordered nothing and having to do nothing to do with VMWare I was confused.

Unpacking the parcel showed a Jaguar remote controlled car with the Veeam logo on its roof.

Beveiliging banken websites (Dutch)

Toen ik vanmorgen een transactie uitvoerde via mijn bank (ASNBank) zag ik dat deze netjes een score van 10 aangaf in ssleuth. Deze add-on is overigens erg handig om een idee te krijgen of de verbinding tussen je webbrowser en de webserver van het website een beetje veilig is. Uiteraard zegt dit niets over de veiligheid van de applicatie bij de bank.

MendelMax 2.5 Z axis support

One of the problems I have with the MendelMax 2.5 is the Z axis. The binding of the axis was and issue and the threads that were delivered with the kit had a huge wobble.

Cheap but good headphone

At work I need some headphones so I can close myself off and concentrate on a specific job. I don’t want some cheap sounding headset, because I know the sound quality will anoy me and I won’t use it.

rss2mantis script update

I’ve been running with the script for a while now, but I found that in some cases no new issue’s were created when they appeared in the RSS feed.

The script stores the local time in the feed status file. When retrieving the RSS feed it compares the RSS feed timestamp to the local time in the status file. Even with timezome compensation, this seems to be an issue.
