Re: Rpi as a scan converter / scaler, possible?

Someone on the stardot Acorn retro forum has produced something that uses a Pi zero and a small CPLD to convert BBC Micro RGB output to HDMI . More recent developments allow it to convert other formats up to VGA. It also does de-interlacing and/or scan lines. Particularly interesting for you is tha...

Rpi as a scan converter / scaler, possible?

Hi, I'd like to know if it's possible to use a rpi as a scaler/scan converter to take an analog video signal (rgb or composite) and convert it (just the analog/digital conversion like scan line doubler) in real time to the hdmi output like the Open Source Scan Converter to connect older game console...

Some rpi1 CPU/GPU questions

Hi, I've got both the Rpi1 b+ v1.2 and the Rpi 3 b+ new version, and sometimes I like to try to use the first older and slower one to see how good it still can act as a desktop light office machine. Obviously everything it's running at the limits and I was thinking what can be done to help the cpu u...

Re: pi3b+ needs better power supply

The Stontronics supply was changed from 2A to2A5 about the time the Pi3B was launched, IIRC. 2A was enough for previous models but 2A5 is recommended for the Pi3B and Pi3B+ to allow the full 1A2 for USB devices. FWIW, having finally acquired the newer version, and had the time to update my webpages...

Worth noting the Official PS is actually 5.1v at the wall end, and uses thick copper wires, so by the time the power gets to the Pi itself, its dropped only slightly to 5v.
And also it should have only the two big power wires and no other communication wires. ;)

Re: pi3b+ needs better power supply

This was mentioned in the launch video, but struggling with current 2A random adapters which have always worked for me with pis in the past. Official raspberry pi adapter is a lot of dollars shipped to Canada. On the lookout for something local... any ideas? 2.5A seems rarer than 2A. From my experi...

Re: Rpi3b+ questions

Nah, I use a C10 / U1 microSD, same size, and so far it's worked perfect. But I've only had the new Pi and SD for 2 days. BTW, love your username (assuming it refers to the Intel i386SX) I'll look how much they ask for the lowest size "cheapest" class A1/A2 if will make any differences. Thank for t...

Re: Rpi3b+ questions

The waiting is most likely your SD card. Does it show a "class rating" on it? (Example: C4, C10, U1) I wonder if the SD card could be faulty and I/O is having to be repeated several times before it works? The system is still fast enough not to mention compared to the rpi1b+ but sometimes the sd led...

Re: Rpi3b+ questions

hmm what is the psu rated at? that is to say what is the powerblock / powerblock with cable rated at? I forgot to say I've the official 5,1v 2,5A power supply with the raspberry logo on it; I bought it specifically to see if this was the problem. About the dvd reader powered by the external power s...

Re: Firefox questions

Another question: I've found that in the trusty-updates page of the packages.ubuntu.com page there's a 53.0.3 armhf build. Are those build ok to use and "official" or not and better go for the esr?

Firefox questions

Hi, I have a Raspberry Pi 2 board and using it with Firefox-esr. I already had some experience with esr x86 version on debian and I have some questions to config this browser at best. 1) Just like in the x86 version I remember having problems enabling the Multiprocess e10 option that if I'm correct ...
