It's a combination of Voron and Ratrig parts joining forces to make an excellent 400x400x400 3d printer running Klipper.

I made a custom Voron 300x300 based on the V1.8 using parts from a Kywoo Tykoon Max and some other parts I had spare. The motion system is from the V1.8 with the rails on the top so the rods can be attached to the frame. The bed is mounted to a custom frame and motion system with dual steppers made on my Workbee CNC cut from 4mm Aluminium and it worked out so much better than I had imagined.

This is part 2 of the Atari 2800 Joystick build and it's finished so we are going to look at the steps to make your own and all the details for the parts.
I call it the Joystaddle !!!
When I mention cutting the shaft down I say 40mm when it's actually 50mm and needs to be reduced to 40mm.
All details and files can be found on printables including free STL

Like I said this is one of the first PC I used at my job when I started to learn Borland Turbo C and I have had a search setup for quite a while. This one was not too far away in Rotheram so just up the M1, but at the time it was snowing so we had to delay the first meetup at a service station.
I do the basic tests, but didn't have a service manual so had to wing it. The keyboard gives me a lot of trouble and the hard drive is stuck.
Some of the information I found along the way.

It's time for an Untested Ebay special and this time I have a ZX Spectrum plus 3 to look at. It came with nothing so just the board and I had to bodge together a power supply for the 5v and 12v, it also needs -12v for the rs232, but I am not interested in that at this time.
I also look at fitting a Gotek to the internal and external ports of the plus 3 and I really did go the long way around on this one.
If you're interested I recommend this guide

Like it said in the video I had one very sad looking spectrum 48k and then one board only and I was not sure what I wanted to do about this and while looking for used or new cases I found the Keyboard PCB from Don superfo
pcbway.com/project/shareproject/ZX_Spectrum_Keyboard.html
As soon as I saw this I had to design a case for it and of course document the process. I like it so much and had enough interest while sharing I ordered more PCB, Key switches and caps so please don't let me down.
This is the Mechanical Keyboard case for the ZX spectrum 48k rubber key computer.
The kit includes the case, mechanical keyboard and key caps plus screws and rubber feet.
Because this is PLA I can't stress enough you really need to remove the heatsink and replace with a switching regulator like the Traco. It's better for the Spectrum anyway.
The kit was tested with issue 3 and 4 boards so not sure about issue 2, but again remove the heatsink and replace with the traco and I am sure it will be ok.

This is part 2 of the Sega Master System series and if you remember I had to replace that rubbish cheap PSU that was causing all the interference. At the start I ordered the Mean Well 9v PSU from ebay and I was confident that would be a good choice and also a polarity inverter so it would work on the SMS. Then the same night I was searching I saw the video from LTT Linus Tech Tips talking about this very subject and it was black friday so I ordered the UGreen Nexode charger and the adafruit power delivery USB-C leads.
The way this works is the Nexode charger supports power delivery protocols and can be told what voltage to output from the USB-C device like a laptop, but in this case the Adafruit lead has a chip in the lead to tell the PSU to output a set voltage like 9V or 12V. Depending on the specs of your PSU you might have something already just like I had the charger from my Pixel 3A mobile, that only supports 5v and 9v, but it would have made a great choice for the SMS if I decided not to order the Nexode. I will get good use out of that charging my studio equipment so money well spent.

A quick part 2 of the ZX Spectrum Diagnostic video. At the end of part one I teased I was making a board with ZIF sockets to make testing easier, but I had a lot of trouble with the risers under the ZIF sockets. It was not possible to fit the ZIF I have becasue of component clearance. My friend also send over a few more chips and we find a working Z80 CPU.

The Diagnostic card is based on the work of Dylan Smith and you can find more details at
github.com/brendanalford/zx-diagnostics/wiki/Firmware
You can buy from myretrostore-uk on ebay
The Diagnostic board has been configured as follows:
Page 0 - Dylan's diagnostic 48k ROM v0.1
Page 4 - Flash utility
Page 5 - Brendon's diagnostic ROM v0.38
Page 6 - Dylan's diagnostic 48k ROM v0.1
Page 7 - Dylan's diagnostic 128k ROM v0.1
To change the default rom on the card you have to use the firmware util built into the card and that requires a working spectrum. I only covered the first steps and this is how to do the rest
To change to boot ROM:
Set page jumper to 2-3
Plug in cartridge
Power on Spectrum
Enter command: CLEAR 32767
Enter command: OUT 31,36
The flash utility will now load
Press enter for other options
Press x for erase
Select 0 (Erase page 0)
When Done, press any key to exit
Press enter for other options
Press c for copy
Select 5 for Brendan's ROM, or 6 for Dylan's 48k ROM or 7 for Dylan's 128k ROM
When Done, press any key to exit
Press enter for other options
Press p for program
Press 0 (ROM is written to page 0)
When Done, press any key to exit
Power off Spectrum.
Change page jumper to 1-2
Power on Spectrum and ROM tests will begin.
The version 0.1 rom will test the memory first and then look at the ULA and I think this is useful if the spectrum has no display, but Brendon's diagnostic ROM v0.38 does provide a lot more tests.

14:33 conclusion
For a while I wanted to use an actual old keyboard with my MiSTer and design an addon for my wedge case so I decided to look at KMK firmware that a lot of people use for custom mechanical keyboard. KMK and Circuit python was very easy to use and just had to change the examples to work with the small selection of keyboards I had to try. While I was working on this I also found the BBC and Amiga 600 projects , but I was not able to borrow an A600 keyboard for the video.

23:18 conclusion
After using the Digilife for a while I wanted to use it for video, but it was just poor quality. I checked what models Adrian and StezStix Fix? used and look at the Andonstar range for something that has HDMI output and recording to SD. My budget limited me to the ADSM 301, but I am very happy with it.
Following on from Ep 1 when I managed to get this MG Headland 286 motherboard to post I continue with the repairs and work on the Keyboard circuit before a lot more testing and some very interesting problems.

If you want a lot more information look at the tread over at Vogons

or my github for the LA files.

I also tested a sound card that uses DMA and that does not work. Without sound Wolf3d will run for hours with no faults, but once installed a sound card and use DMA it started to get buggy and eventually crash, on top of this no digital sounds worked in any game or in the sound card test programs so the DMA is not limited to Floppy access.

25:41 conclusion - The 286 says NO floppy disc for you.
I am a sucker for punishment and after the Acid Atari series I bought this faulty 286 motherboard from ebay, but then put it away for a few months because I couldn't face another epic repair. It turned out to be very generic motherboard and hard to find any documentation for it so I had to make do with what ever I could find. This did cause some problems later on, but I didn't stop me from trying to get it working again.

Please let me know if you would like more details, I still think it needs more work especially on the Z lengths of the frame so the lead screws do not need to be cut.

It has a few options for the type of tips it can take 210 or 245 and I chose the 245 style. You can also select a few tips, but I would recommend just one and then but genuine JBC from a local dealer. You can also buy another handle for the other types of tips if needed.
After a few months use I am happy to recommend this soldering station for anyone, beginner to experienced, the range of JBC tips covers just about any job you could imagine.
I do have a Patreon if you would like to help and support some of the longer projects I am working on.
