This isn't the only way to do it.
It's probably not the best way to do it.
But it's how I did it.

Great mailbag! Please do a rubber stamp project video. I have heard that Santa may be bringing me a laser cutter since I have been extra good this year. Making rubber stamps sounds fun.

[@wasdaletimelapse7658]

Maybe you could reverse the black part of the swing arm supports and stick a laser engraved rubber stamp on it. You would then have your stamp handle, just a thought. thanks for sharing.

[@DustinWatts]

This is a good idea... those things make great stamp handles I would guess. If you can keep them from turning. Maybe some UV glue? Or just CA glue. Btw... stamp handles, makes me think of "fork handles".😅

[@wasdaletimelapse7658]

@@DustinWatts Ah yes, good old "Two Ronnies"🤣

[@jjab99]

It would be interesting to see you making some stamps with the rubber that you received today. Keep up the great work. Take care and stay safe, Joe

[@AndyCallaway]

Yes! Rubber stamps please. 😃

[@tinygriffy]

Thanks for the MM video !

[@wooferhound7571]

You could use the Motorcycle Pegs as handles for your Rubber Stamps. I have played with the DMX Decoders a lot. Great way to increase the number of PWM outputs on Arduinos plus increases to output to 1 amp. Got the 6, 8 and 30 channels versions. I use Arduino Nano to drive a DMX module to operate the Decoders. They are made to you can control any voltage that you feed to them. I used a 30 channel version to make a 3D Hanging Starfield display at the place I work in the US Space & Rocket Center here in Huntsville AL. Each channel drives a 1watt LED hanging from random lengths of wire with some channels driving colored LEDs that are lighting up the ceiling over the display.

[@onecircuit-as]

Great mailbag! The led controller pcb looks very interesting. Looking forward to it being deployed. 👍😀

[@rorymacleod8488]

stamp project would be fun !! now go out and Shovel !!!

[@pileofstuff]

Already been shovelling 3 times in the last 24 hours...

[@richards7909]

The rubber stamp would be interesting even if it doesnt work! As an aside to this, perhaps mount the pad to a piece of wood with magnets in so you can attach a swappable generic handle? :)

[@ronm6585]

Thank you.

[@SidneyCritic]

Other than spacers and washers, maybe a bunch screwed in a line on a piece of wood could be used as a cable hanger.

[@retireeelectronics2649]

Like those LED flicker flames.

[@pileofstuff]

Yeah, they're pretty cool looking.

[@frankowalker4662]

You could put the flickering lights on the christmas tree. I'd love to see you make a rubber stamp. I imagine the fumes would be pretty bad though.

[@pileofstuff]

My ventilation solution deals with fumes from the laser pretty effectively.

[@frankowalker4662]

@@pileofstuff That's good to hear. Looking forward to seeing what you make 😃

[@TheUnofficialMaker]

swing arm: may be you can use it as a pulley, make some kind of spinning thingy., small turntable. I'd like to see the video on the rubber stamp sheet.

[@Hasitier]

It is also possible to print such stamps with a flexible filament. Done this before for my wife’s job. Works well. And as I do not have a laser engraver but a 3d printer…

[@pileofstuff]

I've experimented with flexibles in my printer, but it didn't end well. I think I would need d direct drive extruder for it to be a viable option

[@Hasitier]

@ I am running an old Cr 10 mini. I just modified the extruder to a dual geared one and I still use the Bowden tube as it was stock. Works fine even with highly flexible Ninjaflex.

[@ozisnice]

Interesting to see if you can make stamps with that. Finding correct one usually is a pain .

[@pileofstuff]

It will be an inserting experiment. No idea if it'll work, but that's part of the challenge.

[@gordanmilne7034]

​@@pileofstuffBe careful of what you insert and where!

[@hugovangalen]

In theory this could be great, I'm very curious how this works.

[@RohitDutta420]

2:13 does anyone have a listing of that power supply? I cannot find any.

[@johncoops6897]

@@RohitDutta420 - The power supply is a *B3603* with 36V 3A max output Buck Converter. Pile'O printed or fabri-cobbled that ugly enclosure for it. They were originally made by MingHe (Zhengzhou Ming He Electronic Technology Co., Ltd.) and also sold under the brand name of Junctek BUCK3603. They are excellent products, however the pushbutton interface is annoying compared to the more modern ones. I'd suggest getting a more modern unit like Fsnirsi DC580, or ZK-4KX or Whuzi WZ3605SE, or the SK35H, SK40, SK40C, SK90 and SK90C (add XY- for full part numbers), or the XYH3606 and XYS3580 - all of which have Buck+Boost, a better display and rotary encoder for input. An EXCELLENT item currently on Ali is the "SK120 DC Buck Boost Converter CNC" (often also found by search of "SK60") which is actually the XY-SK120 from XINYI SiniLink - then find a listing with the "finished" option which includes an excellent aluminium enclosure, banana plug outputs, USB Type C PD-trigger input, etc for about USD $21 or so including shipping. 👍

[@kyleallred984]

If you have enough, possibly a roller coaster. 4 on track, and 4 inside track.

[@jyvben1520]

metric screw in support ? just need matching nut or thread tap, green bit use as a led holder for the dmx led controller, or stick them on a big light bulb

[@fredflintstone1]

Yea!!, Monday, Monday, So good to me, Monday morning, It was all I hoped it would be 🙂

[@TheEmbeddedHobbyist]

Be careful with the rubber sheet when burning with the laser, keep the area well ventilated as fumes can be harmful.

[@pileofstuff]

I've got a ventilation on the laser's enclosure that pulls the smoke and fumes outside.

[@tinygriffy]

Yeah I suppose that might be a smell you will never get out of your machine again 😅

[@wardprocter2371]

I think it’s pretty obvious at this point….you need to buy a motorcycle 😂 Looking forward to both the DMX board and the rubber stamp video.

[@MrBobWareham]

You should change your hand pointing tool for a LED one, it would look cool

[@circadianrebel]

Here is my theory: Someone keeps trying to buy that motorcycle part for themself, but they don't realize their default shipping address was set to your address when they sent you something once, so the part keeps getting shipped to you and they never receive it so they dispute the order and place a new one, but don't verify their address so it again gets sent to you, etc.

[@pileofstuff]

LoL!

[@AsilarWindsailor]

I wonder how useful that DMX driver is with things other than LEDs. Say, something like driving motors or other electronics not intended for use with it. As far as all the motorcycle pegs, maybe the pulley idea could be elaborated on a bit and make a sort of rope track to move an overhead camera on for a little flyby shot of the workbench or a train set perhaps

[@pileofstuff]

Interesting Idea. I wonder if it could power a DC motor ?

[@DustinWatts]

I wonder if the three outputs are also in parallel. And 👀 The stamp project please. Something I want to do too. So that way I can learn from you mistakes 😝

[@pileofstuff]

I'm sure there will be plenty of mistakes to learn from...

[@DustinWatts]

@@pileofstuff I like learning from mistakes. Preferably from others mistakes.

[@wallaceshackleton1889]

Another great episode of "Why the hell did I buy that!" :) These motorbike bobbins must be somone's idea a joke, so how about a "competition" for suggested uses for them?

[@johncoops6897]

They screw into the rear axle of the bike. When you want to lift the bike onto a (axle) service stand, you slip the 2 arms onto the 2 protruding peg thingies that protrude out from each side. He already described this clearly at 6:41 onwards. Alternative uses might be as cleats to retain for few wraps of rope, or as a peg hook to hang a coat etc onto. You could screw a heap of them into drilled & tapped holes in a tortoise shell, to produce a steampunk reptile that is resistant to eagle attacks. This might also be an advantage in competition tortoise fighting.

[@robertcromwell9736]

So you ordered a plastic sheet?

[@cb-1100]

Bike lifter = drawer Handel

[@George_Salt]

Laser cutting rubber... that's going to stink!

[@pileofstuff]

Probably. Good thing I have ventilation connected to the laser's enclosure.

[@matambale]

Are the swingarm stand spools always coming from the same seller?

[@GnuReligion]

Maybe some of his subs are trolling him? How many Yamaha swingarm spools does one actually NEED?

[@pileofstuff]

I don't think so. I suspect it's the same person buying them from whatever seller has a low price auction.

[@pileofstuff]

It's definitely possible that someone is having a laugh at me continually opening these things.

[@squalazzo]

you can just select "buy it now" option on the left, you know, to NOT get the auctions on top :)

[@pileofstuff]

Of course, but the auctions can often be a very good deal, if you can get it. I'm assuming most of the random gifts from viewers were purchased as cheap auctions.
