That'll be easy enough to find if there is a backhoe anywhere within a 2 mile radius.

The conduit was laid at the same time as the armoured cable for power, and getting power to RC2014 Towers was a big motivation there. https://mastodon.me.uk/@semachthemonkey/112620532543080981

There is 40+ meters of conduit buried along the perimeter of the garden that comes out inside #rc2014towers
And that is it so far. I still need to route the conduit at the house end, buy some fibre and pull it through, and sort out a couple of switches each end that take fibre and cat6

Well, I'm not saying that Costco membership will pay for itself with the stroopwafel savings... but maybe it's worth calculating how many you would have to eat to make it worthwhile ;-)

I just got back from Costco and came here to say exactly that.
Well, almost exactly that. They're 5.89 (plus vat?) at Costco Derby. So that makes them 14p each.

Well, the RC2014 was never built with production in mind, so it didn't cross my mind to try selling it until about 9 years ago.
But I think the Z80 Membership Card is still available.

Oh, and in case you're wondering, yes, I will be entering. I have some unfinished challenges from a few years back that I really should revisit. Wish me luck :-)

2024-09-01 17:27:47 GMT

I took part in my first Retro Challenge 10 years ago now, building a little Z80 based computer that I used the #RC2014 hashtag for. (See https://sowen.com/653/retro-challenge-2014/ for my original entry!).
Well, for the 10th anniversary, not only will there be a specific RC2014 section to enter, but I will be sponsoring a prize for #RC2024
Things kick off in 1 month, so you haven't got long to get your entry in. Sign up here https://www.retrochallenge.org/2024/08/rc202410-registration-is-open.html and good luck!

I have only tested it reading, and, yes, it works. Although, sadly, it doesn't recognise the EEPROMs I mainly use.
I do have some chips that I think it should work with, although I am waiting for an opportunity to need to program one.

Sadly that has the wrong logo to match my programmer. I guess I'll just have to wait for another one to come along...

Well, I haven't actually used Google Photos for quite a few years, so it doesn't really affect me. But it means that I can't check either. Although it might limit the amount of photos of me that people can find!

At the weekend I went to Hebden Bridge for the #WutheringBytes festival including #OSHCamp.
On Saturday I gave a talk about dye sublimation printing on to PCBs. Most of that talk was from this blog I wrote last year https://rc2014.co.uk/2293/dye-sublimation-printing-on-pcbs-for-rc2014-pride/
On Sunday I ran a workshop where people could design their own artwork to go on to a PCB. This could then be assembled in to an electronic dice. If anybody is interested the files for the workshop are here https://rc2014.co.uk/OSHCamp2024/

[@trans_rescue](https://mastodon.social/@trans_rescue ) if they can make a 4k7 resistor then I'll happily send money their way.

2024-08-27 20:35:03 GMT

- reply

Yup, that's pretty much it. The transistors/resistors/caps give around a 65Hz pulse. Whenever the button is pushed it sends those pulses to the decade counter. That counter counts up by 1 each time, and resets to 1 again when it reaches 7. So one of 6 outputs is on. The diodes set which LEDs are on, based on whichever of the 6 outputs is on

I never remember a time when TVs just worked out of the box. Tuning them in was always a pain, so every few years they developed new ways to do it. That meant when you got a new TV you had to learn how to tune it in because it wasn't the same as the one you had.
Then Channel 5 came along in the UK. And they actually employed people around to go around tuning in TVs. But the frequency overlapped with games consoles, so those needed retuning (which the C5 people wouldn't do)
