    HP Prodesk 405 G4 DeskMini

    So this was about to be yeeted into the e-waste at work when one of my colleagues stopped it from going in the bin, putting it on my desk instead. I love these little USFF 1L machines, they pack so much into such a tight space, and this appeared to be no different. Opening it up, oh, a...

    Random eBay pickups

    Couldn't resist picking up one of these for just £9! I recently got an InWin case I've been after for 24 years, courtesy of @Stinkerton18 so I have the idea to do the build I had before project Middlesex and what better place to start? Project Letchworth is a go, too! Of course this was...

    Steelseries Rival 310 repair

    A rather odd thing happened between 2023 and 2024 - before Christmas, the mouse I used at work, a Steelseries Rival 310 worked just fine. After Christmas, in the new year when I came back to work, the mouse had stopped working except for the button click. This was very odd, nothing in the...

    Simple garden table refurbishment

    We purchased a 20 year old ex-pub bench from a couple that lived around the corner, shortly after we moved in. Despite being 20 years old, it was in fairly good condition. However, the elements started to take its toll over the last year or so, what with it being the wettest year ever...

    Dell R520 - The expansion continues...

    For those that are unaware, the TD Game server is run on a Dell R520 - as shown here: https://tinkerdifferent.com/threads/tinkerdifferent-game-server-now-testing.2909/ In modern terms, it's ancient, was destined for the e-waste until i rescued it. I mean, who'd want a 10-core, 20 thread...

    https://www.techspot.com/news/102684-zilog-discontinuing-z80-microprocessor-after-almost-50-years.html While nothing Apple made uses the Z80 specifically, the Z85C3008VEG PLCC44 and Z85C3008PEG PDIP-40 (aka the 85C30 SCC) used in a lot of 68K Macs, is also being discontinued. If you're...

    Anyone else a huge fan of the Alien franchise?

    I grew up as a massive fan of the first two films (the others not so much), which was helped by the fact my mum had a very, very tiny hand in both of them as a seamstress working in the props/costuming department. While i went out of my way to try and enjoy Prometheus and Covenant, i really just...

    Regarding ban on 2024-01-29

    Recently, some of you may be aware of a ban handed out to a now former member of our community. The reason for that members ban is still valid and the ban will therefore stand (Reason: Violation of the code of conduct). However, the language used in the ban message itself was not just...

    Texas Instruments discontinuing a lot of IC's

    This is more of a heads up - if you're building any Reloaded boards, please now be aware that TI have been curtailing their product lines, so things like the SN75150 (replaces the MC3488 in the SE Reloaded) & SN75175 RS-422/RS-485 serial interface IC's used in the SE/30 Reloaded and more, are...

    TinkerDifferent Game Server - Now testing!

    This has been on the cards for a while, and i've just gotten a Dell R520 handed to me for the sum of £0 - ie, 'take it away or we're throwing it away' (perks of the job!). Oh look, here's Gary inspecting it now... To be honest, these Dell servers are more than enough for a community game...

    Time for an Athlon-XP Build - Project Middlesex (Now with pretty pictures!)

    Almost 20 years ago (jesus, that hurts to say now), I was nearly ready to begin my computing course at Middlesex University in North London. Disappointment of the course and ineptitude of the University aside, I had put together a damn good rig to handle almost everything that you could throw...

    Christmas Buffet Foods

    This year, @boopbox123 and I are eschewing the norms of british culinary tradition during the primary gifting period and choosing to instead have buffet food on the day itself, instead of boxing day, which is normally what happens. Reasons for this are mostly because we can prepare almost...

    TinkerDifferent - Gamer Tags & Usernames

    This weekend, I was thinking about the fact we're at 700+ members and some of us might also game, on some platform or another. To this end, i've made a simple spreadsheet here if you want to add yourself and open up your friends list. I've added my name to the pot already :)...

    The Mega Shed

    So, we're moving from a room in 2nd floor apartment, to a our own ground floor apartment with 2 bedrooms and a garden. Now, the Mrs wants to be able to have a garden space to herself and I have just the idea. In the garden is a concrete base suitable for a garden shed. This will not just be any...

    1979 Olympus OM-10 SLR Camera

    I just found this in a charity shop for £30 - a bargain if you ask me, even if it had issues. However, i picked this thing off the shelf and to my amazement, it seems to work just fine. Shutter speed, ISO, all adjustable and seem to work - the battery inside it is still chugging away! The film...
