I’ve been quiet for some time again becaus I became a member of the vieHAB Project. It was started about 4 years ago by Erwin (OE1FEA) but remained dorment for the most of this time. We met at the monthly Metafunk amateur radio meeting where I attended a course to get my ham radio license.
Basically I wanted to do such a project for a long time but never got around doing it. So I jumped the opportunity and became hardware guy. The whole project will be published as OSHW. For our first start vieHAB-1 we will use ready to use modules like an arduino and ublox gps on breakout boards with a backplane.
It is planned to have 2 cams, 2 temperature and preassure sensors, 2m and 70cm radio, GPS and SD-card on board for the first start. I will keep you posted on progress every now and then.
Sooo, I finallly got around setting up my raspberry, nothing too special but maybe it helps some people.
The thing with the screen was rather easily resolved (if only I could have been able to see something :).
It involves pretty much tinkering and the trapezoid picture of the tube didn’t help.
In the end I added to the /boot/config.txt file to this:
The framebuffer_width/height are set back to normal.
Hi, I just started a dream project: Building an oscilloscope from scratch. Originally I wanted to use a russian 13LO37I but it turend out to be too bulky so I went and scored a waaay smaller 3KP1 / DG 7-113 from ebay.
I’ll put up a high res Photo of the tubes weiring system at my website.
This is ust a very short overview about my old 400 MHz/64 Mb RAM Laptop computer, that I turned into a serial terminal after usb stopped working and the body-case broke open. Unfortunately I couldn’t find the original layout for the board anymore but it followed the usual max232 schematics anyway.
Hi, I just received another electronic Kit: The AVR-NET-IO from Pollin electronics. It is awesome! for less than the price of an Arduino you get a network-enabled Atmega32 Board with all connectors routed to some I/O pins and a sub-D 25.
I wanted another Arduino because I don’t want to dismantle a work-in progress every time I start another one. So I got this NKC electronic manufactured Freeduino Kit from physicalcomputing.at for 22 € + shipping.
