Ever seen a seemingly ok, quite new 24″ Syncmaster SA300 LCD monitor from Samsung – which refuses to show an image, but can display its own system messages? Try a firmware update! I found this solution in the PC Help Forum. A firmware update for a computer monitor you wonder? Yes! Obviously you need a… Continue reading Dark Samsung?

Hacking an AVR programmer
(see also my recent appendix to this topic: Hacking an AVR programmer II – especially if you have an ATmega88-based programmer!) On eBay I recently purchased a set of cute small USB AVR programmers which I intend to use in the course 1TE663 Microcontroller Programming at Uppsala University. After waiting for one month for the… Continue reading Hacking an AVR programmer

The parallel port mystery Have you ever used or considered using the parallel port of your computer to control your own electronics project? Well, I have, and this was not my first project. But this time I ran into trouble… With modern versions of Windows it is not easy to get control over the parallel… Continue reading Troubleshooting against all odds I I am quite satisfied with the installation of Windows 7 on my laptop which I bought in June last year. However, one thing has bothered me almost all the time: Creating a new folder in the standard file save dialog from any application did indeed create a new folder – but the display did not… Continue reading Folder refresh under Windows 7 A couple of years ago I presented a preamplifier on my homepage which allowed it to use standard oscilloscope probes on the line input of a soundcard. This small circuit solved the problem that a soundcard has quite a low impedance on its line inputs which makes it unusable for measuring high-impedance signals. Already at… Continue reading A new soundcard oscilloscope As I have reported earlier, I decided to run webmin on my new server. I have also reported about my UPS which keeps my server running whenever Vattenf*ll fails to supply my flat with electricity — at least for about half an hour before the server is controllably shut down. Now with new batteries in… Continue reading Webmin and apcupsd Today I finally managed to get the four new batteries for my UPS unit. Now everything is green again: I thought this was it – well it wasn’t… This weekend I put everything together again: the server and all four harddisks (one system hdd and three data hdds in RAID 5).
