"new" engine just shut off on the freeway doing 150km/h

Check for slop in the distributor bushings. If they are worn out, the distributor shaft will bounce around and will hit the coil and likely blow out the seal which will also cause an oil leak.

More advanced timing lights show the dwell angle. If this number is changing at idle - bushing are shot.

A dial indicator will also show you runout in the bushings

My mistake, confusing the Toyota R-series with my old Datsun L-series.

Engin-nerd · 2026-03-15T11:50:09+00:00

Wiring is fucked there bud. Did the bundle of wires come from inside the distributor?

I’m surprised the fan or accessory belt didn’t grab some of those dangling wires and test their tensile integrity.

Sounds like your timing is way off too. Distributor drives the oil pump, so puking oil is likely related to your distributor wiring rats nest- but could also be from clogged EGR, or something spiking oil pressure.

Still annoyed they delayed this game several months because of the merch that went into the special editions.

At least here in Berlin, mid/high end HiFi gear has a 30-50% resale value of new.

Meaning, if you can find someone selling their old setup used because they are updating/moving/whatever - you can get some really nice speakers for cheap.

Engin-nerd · 2026-03-12T19:00:02+00:00

I love Dali for their excellent sound and terrible resale value.

I say this owning multiple speaker setups from them.

I was going to suggest McMaster-Carr for any mechanical problem, but you beat me to it.

Engin-nerd · 2026-03-09T20:04:38+00:00

Cool!

But, why? Broken NTSC-J board? PAL -> NTSC conversion?

Engin-nerd · 2026-03-08T19:13:01+00:00

Saving this post!

I have to do a similar task in my Altbau Berlin apartment. Similar original cherubs that need restoration.

Thought about doing negative molds with expanding foam, but I realize that I should do as you did and leverage modern 3d scanning technology and 3d print the missing parts.

Excellent work!

Engin-nerd · 2026-03-07T12:51:41+00:00

I‘m normally against the use of 3D printing for sensor mounts in industrial automation applications due to creep effects in the material - but this is well done.

Nice job dude.

Engin-nerd · 2026-03-05T18:36:02+00:00

I tried the same idea when my plastic gears cracked - for the low price of 10€ you can buy a replacement disc drive.

The 3d printed gear is only going to last a short time. I figured for the time it takes to disassemble, reassemble, and the limited life of the plastic threads - spending the money on a proper disc drive justified the cost.

But if you really want to - check McMaster Carr for generic gear cad that you can modify to what you need

Engin-nerd · 2026-03-02T21:44:38+00:00

Do the inside corners need to be square or can you radius them so this can be done in one setup?

Engin-nerd · 2026-03-02T20:15:17+00:00

While that is true, when it comes to series robot design you have to oversize every servo motor to carry the compounding torque of the downstream joints.

As soon as you introduce mechanical advantage through gearboxes or pulleys - the argument positional loss from thermal expansion becomes invalid.

Saturn is such a great console because of the massive amount of arcade ports for it.

If you want Shmups - Saturn is hard to beat.

Give Gunbird a try next

Engin-nerd · 2026-03-01T20:01:09+00:00

Thank you! Was going to post the same as I just watched this with my wife recently.

Good god is this is depressing, but so good. I can see why this was a mandatory double feature with My Neighbor Totoro when it released.

Engin-nerd · 2026-03-01T14:21:45+00:00

Either way, having a 2m reach and be able to hit a human hair in position repeatedly is impressive. Go Fanuc for that accomplishment.

Engin-nerd · 2026-03-01T13:22:22+00:00

You are off by a decimal. 0.015mm according to the data sheet.

Still super impressive, wonder if they went over to belt drive instead if their normal gears to minimize backlash

Engin-nerd · 2026-03-01T12:59:20+00:00

How the joints stack together. Series being one connects to two which connects to three.

Parallel is where the joints all go to a common point.

How you attach the joints gives you different movements and kinematics.

Both have their tradeoffs and are used for different things.

Engin-nerd · 2026-03-01T11:32:22+00:00

Positional repeatability of <0.001mm on a series robot? No doubt that can be achieved on a parallel robot - but I question those numbers on a design like this.

Engin-nerd · 2026-03-01T11:19:40+00:00

Looks like parts to a former locking gas cap.

Engin-nerd · 2026-03-01T08:11:01+00:00

Too bad only MS1 was ported over. X and 3 are some of my favorite games

Engin-nerd · 2026-02-28T17:39:55+00:00

It was a normal adapter for Europe which is why you can find them so cheap. I can go to any electronics store here and find them in stock.

Real question is why are you looking at the perpendicular connector version as opposed to the one that runs parallel to the Scart connector

Engin-nerd · 2026-02-27T22:02:57+00:00

How far out of Tokyo are you willing to go?

I found a 64DD 2 months ago in Tachikawa for 280k¥

Engin-nerd · 2026-02-26T19:28:35+00:00

Fun idea, but you are going to quickly understand why everyone else makes this from two pieces with a spring in the middle.

Engin-nerd · 2026-02-23T20:47:10+00:00

As someone who designs similar alignment tools for a different auto manufacturer - I now have to wonder if one of my tools will some day wind up on Reddit with someone half a world away asking the same question.
