Member Videos / VORTRIXE & OKMO 1110 Classic Model Vintage Engine - First Run
« Last post by Jim Dobson on January 03, 2026, 05:06:59 PM »

VORTRIXE & OKMO 1110 Classic Model Vintage Japanese Yanmar Gasoline Engine with metal piston rings.

1950s Yanmar diesel engines are prized vintage Japanese machines, especially from their pioneering K-Series (like the K1/K2) launched in the early '50s for farming, known for being small, light ("karui," "klein"), and reliable, with many still running today due to Japanese manufacturing quality, often used in small boats, generators, and farm equipment, showcasing Yanmar's early innovation after developing the world's first practical small diesel in the 1930s.

This absolutely beautifully detailed and ready to run model petrol/ gasoline 4 stroke horizontal engine is made by OKMO.  Beautiful miniature engineering, and craftsmanship from Jin.

I can't find my github repository, it's out there somewhere...

In the meantime I zipped up the schematics and micropython code

Ade, we're drowning in bot new user requests -- I can't handle them any more.

I can't help you here - I don't have the permissions - but try putting a block on any IPs from Singapore: Most of the bots seem to be in data centres there these days. Other countries which are problematic - China obviously, also Brazil to a slightly lesser extent.  But Singapore is likely your culprit. I've blocked them from MEM & LEF using iptables rules & just blocking out giant ranges of IP addresses. Sadly, that does cut a few legitimate users off, but it also keeps the server afloat.

Thanks Ade but I don't have the permissions either. Just a mod.

Can you not get a good 9mm or some thing to sort them out :D
PS: AdeV, Tony STILL only has the rear bodywork to Paint and the Ford40 will be finished.
Been that way for 3 years...Motor sounds ace. you need to get down here and see it.

The GT40? COOL!

Where's he based? I'd love to pop down & see it, even if it's not finished, I bet the old man would be interested too.

I never kept his contact details unfortunately.

Braving the cold, Ihad to try it.

It really is a jungle of all kinds of possible and impossible options, no matter if it's Linux or Windows.

But yeah, enabling 32-bit repository is one of the first steps in the Wine installation instructions mentioned before: sudo dpkg --add-architecture i386

General stories and gripes ahead:

Must have Win apps that I use with Wine are ancient Paint Shop Pro 8, and Goldwave.

I'd use Winamp too, but it's rather quirky to use with Wine. Sudden crashes and whatnot. I've always used it in its basic form (since Win 2000), without any fancy visualizations.

Winamp is probably the only music player that has a working plugin to re-connect to the network stream, when it cuts out. It's called 'silence detector'.

On to the alternatives. Although VLC has 'Auto re-connect' option in its preferences, it doesn't work the way one might expect, if at all. After trying some bash scripts found on the net, (and even ones produced by the infamous ChatGPT) to fix the problem, none of them worked. Got to love the dead air.

Qmmp, Audacious, and bunch of other players don't seem to have that function either.

Anyway, then I thought, that how about looking, what's happening when the stream cuts off. Wireshark is a free tool that I used back when testing Win10 to see where it sends telemetry data. If memory serves, there were tutorials of how to do that.

When using it in this case, I got some indications, when the net radio stream cuts or drops, but can't figure out what to do with that data.

So, I have a habit of jumping to the deep end of the pool, even though I can barely swim  [ You are not allowed to view this attachment ]  .

In that vein, another example: trying to make GPU (display card) passthrough, so that the VM has a real hardware resources (3D acceleration for apps like Rhinoceros that I've used quite a lot on Windows), instead of virtual ones. It may be possible using single GPU, but it's really not that convenient to use - shut down the primary host display service/device, so that VM can use it.

I insisted on testing that procedure anyway, and since such things can't, for obvious reasons, be tested inside VM, I ended up bricking the Linux installation on my pc.

More viable option would be to have two GPU's, perhaps just an integrated one for the host, and dedicated one for VM. However, my motherboard or CPU don't have integrated GPU's, so that's the end of the story about that, for now.

All too blooming complicated for me these days - bring back CP/M is what I say.

Happy New Year everybody.

This black resin is really sticky stuff when cold, cleaing it off was a bit of a bugger.

The case clips together, so Im not at all sure if it'll come apart in one piece

Santa brought me a garage door for an early Christmas present, he's also bringing me a P1S/AMS combo as a late Christmas present.  The gaping hole in the front of my garage is now filled and the building is weather-tight.  Insulating it, or any other work on the inside, is going to have to wait for warmer weather.

I tried printing some larger than 200mm stuff  on the MP10 and it crapped out again, that's why Santa's bringing me the late present.

I also decided it was time to install the Micro Swiss all-metal hot end on the D6.  In the process I discovered the root cause of the jamming issue I'd been having on it.  The D6 uses an aluminum block with a series of slots milled in it as a heatsink for the heat break.  This block is bolted to the bottom of the extruder drive, which caps off the open top of the slots.  The cooling fan blows air through the slots to cool the heat break.  The Micro Swiss all metal hot end replaces this heatsink with one of their own design.  I found 2 things that were issues with the original heatsink.  First, at least 75% of the cooling slots were blocked off with dust,  This would cause heat creep, and eventually the filament would be melting in the heat break, not the nozzle, causing a jam.  I'm going to have to blow these slots out once in a while or the same thing will happen to the Micro Swiss heatsink.  (When I found that issue I almost regretted ordering the P1S, until I remembered that to get a quality print out of the D6 I have to print at 60mm/sec, while they recommend 200mm/sec on the P1S.)  The second issue I found was that the slots that were right next to where the heat break went through the heatsink had no exit, they were dead-headed so about 25% of the heatsink NEVER worked properly.  The cooling fan could pressurize the slots, but that air would be static so it wouldn't help cool the heatsink.  Those slots didn't have any dust in them which shows no air was circulating through them.  The Micro Swiss heatsink has an exit milled in for these slots. 

I finally found some 1/4"x1/2" aluminum flat bar for the RT7's upper frame rails, so I'm going back to Plan A and using the aluminum frame rails.  They'll be a little easier to machine on the equipment I've got.
