Measure your city (meetjestad)
Recently, I have found good use for my LoRaWAN gateway. Together with a few other enthusiasts I’ve assembled a measurement device for the Tilburg branch of the “Meet je Stad” project. This project started in Amersfoort, and combines measurements of (currently) temperature and humidity from relatively cheap devices at peoples’ homes. The data is sent […]

15kHz on LCD monitors
15kHz monitors Most PC monitors made for VGA and later graphics adapters have a horizontal sync of 31.5kHz or higher, but most home computers including the Commodore Amiga line, as well as CGA and EGA for PC, have a hsync of about 15kHz as standard (PAL or NTSC). Many ‘recent’ monitors therefore do not properly […]

Our company uses C#, Javascript, HTML and CSS and various (Microsoft) .NET technologies. It’s an exciting change and I will try to keep this blog updated with my progress. Prior experience I’ve […]

Athom Homey
On the 10th of February, 2016 I received my Homey by Athom. It’s a home automation hub which listens to you and speaks back, and can control all kinds of devices. It has just been released, which means there’s still quite some bugs. So I will list here what has worked for me, and what hasn’t. […]

Apple IIc from Scryption collection
I recently bought some of the ‘leftovers’ from the Scryption Museum which unfortunately had to close due to lack of funding. Here’s one of the systems I bought from them, an Apple IIc with matching monitor and power brick. It powers up, displaying “Apple //c” and “Check Disk Drive.” messages. Hitting Ctrl-Reset gives me a […]

I had hoped to be able to install a Linux-based third party firmware (like Tomato, OpenWRT, dd-WRT, etc) but couldn’t find a lot about this router. It appears to work fine […]
