Re: What was your first computer?

eee... we used t'DREAM of punched cards! My first computer experience was a Ferranti Pegasus (valves, from the late 1950s) that had been pensioned off from the commercial/military world, or maybe the MoD itself, to the local technical college where it was used to teach us students in the early 1970s...

Re: What was your first computer?

Yes. It wasn't my personal computer though. I was a fresh-faced PhD student doing research with an SRC grant. It did cost £thousands in total, and I spent a lot of time soldering, and then programming in Basic and Assembler! Happy days. If only I had a Pi then. (I guess I'm a couple of years older t...

Re: What was your first computer?

MSI-6800 built from a kit, in 1977. Eventually upgraded to 48K of RAM on 6 large PCBs, 8K each! Initially used a paper tape reader/punch via a teletype (110 baud RS-232 anyone?) and finally got a 160K 5.25" floppy drive. Magic.

Re: Breakout board that will give all ports on one side?

I have built a few Pis into custom boxes I made using HDMI and 3.5mm mini-jack stub cables (i.e. very short male-to-female cables). The block of USB sockets and network connector on the Pi poke directly out of the back of the box, and the stub cables bring the other connectors to the same panel - al...

Re: Wi-Fi issue powering Pi from gpio

If you fully recharge the NiMH batteries and try again, does it work then? EXACTLY what DC voltage are you feeding to the Pi when the Wifi isn't working? Rather than a fixed IC regulator, you might have more success with a DC-DC "buck" converter module, because they have an adjustable output, and yo...

When following the link above, do remember that that Amazon page carries TWO versions of this heatsink:

- one for the Pi 2 and 3B
- one for the Pi 3B+.

Make sure to get the right one!

It's called an "MCX" (Micro Coaxial) socket. It might be worth reading from here onwards:

Re: Idea for the DVB TV Hat - capturing old videos / digicams - will this work?

Agreed - sadly this won't work. The TV-HAT is for digital DVB Broadcast signals only. You won't be able to convert your old VHS recordings etc. into that format. You need another capture device as mentioned above to capture either composite video or UHF analogue TV signals.

Re: distinguish between booting and rebooting

Write a unique string of text into some volatile storage (RAM) and then after a boot/reboot:

- if the string's still there, it was probably a warm soft reboot; but
- if the string's not there, it was probably a cold hard boot?

Any good?
