I never understood a single video from this guy.I keep watching and disliking and watching.

26:38 missed that the first 5 times of watching this video.

25:40 Why won't you use a cheap magnetic absolute sensor (something like an as5600). Absolute positioning would delete the need for homing and then just do your constant velocity moves. Just a bang bang controller would probably be enough

Do have a wiring diagram available for the project. I am currently trying to replicate what you have done for a gantry robot. Since in the past I have only worked with 24 V, I am a little bit insecure about the 220 V AC. Also, what kind of filter and fuse do you use?

Another giant monster piece. As a "mathless" brain possessor, I feel like a congenital quadriplegic watching the Olympics when viewing videos such as this one. I can FEEL it. but I can't DO it. Pain in the ass.

In he old days, phone company in NL used acid-free vaseline for lubricating copper contacts. Works well.

Why are you rolling your Rs all of a sudden? Watching too much 'Are You Being Served?' haha

It sounds a bit like Duke Nukem. I love it!

I’ve been to the Loveland facility in Colorado .

Why don’t you use an as5600 magnetic encoder for positioning. They’re less than $5 and super accurate.

Hey, don't call me out on the ignition distributors like that!

The last technology connections video about pinball incidentally shows spring-loaded contacts used for the machine logic. You said that you didn't want lasercut springs, but what about regular coil springs instead?

In always surprised by your new diversions. Could you revisit your solar install and assess how the effort has paid off, or not?

Shiny surface finishes come from Kern or Diamonds... if you want to repeat your sphere with a diamond, I'd be happy to lend you one. Fantastic video!

Maybe a light barrier for homing?

UNLEADED 🤣

@ 7:46 "manspreader.step" lol

Thinking of a completely different approach:- See the gold spring contacts on the Keithley 480 Picoammeter at 27:20 of Dave Jones video: kzbin.info/www/bejne/sHXGnWNjqZyWm7s Shouldn't be too hard to find some suitable springy material, and get it gold plated, then operate the springs by plastic rods driven remotely by small cheap solenoids. ?

This is great video! I've been using Monport Laser for several months now, and I've been amazed by its versatility. While MOPA Fiber Laser Engravers can handle a range of tasks like welding, cutting, cleaning, and coloring, Monport Laser takes it a step further. With Monport Laser, I've been able to tackle not just engraving, but also precise milling tasks with ease. Its intuitive interface and robust performance make it a standout choice for various applications. Whether you're working on intricate designs or heavy-duty projects, Monport Laser delivers exceptional results every time.

AWESOME

Congratulations on the beautiful videos, I wanted to know if I can machine PCBs with a 20 watt diode laser

highly recommned nanovolt accuracy switches video.... was memorable

Very nice work. My only comment is that 30% Z load at idle isn't really that bad. You don't want it fully balanced, and having the weight of the Z-axis help in plunging loads is helpful.

Neat stuff. I think all cars have switched to clock spring style connections to the steering wheel. What about a motorized rack to engage the connectors? That way they wouldn't drag and they wouldn't connect until positioned. I agree with other here that a pair of contacts at the end of travel for homing would be better. Or if you go with lifting the wipers like I mentioned you could use something like pogo pins for the end indication.

so we're looking for... weighthless unintelligent switch for electronics?

On the Prusa slicer comment: if you make an extremely small cut in your model you can trick the slicer into going back further. If you do every other you can get a lattice connection.

Awesome to see all this work. Nanovolt realm is not for everyone. Great video.

ADR1001 when???

Try soldering reed contacts radialy and a glue a piece of magnet on cursor then fly it over desired reed contact with the steper ... no heat there no oxidation, maybe is what you need!? (you can use existing pcb if you find reed's small enough)

Slip rings in steering wheels are basically not a thing anymore, they use a winding spring flex pcb cable to allow for ~3-5 turns in each direction. Before airbags were a thing that was different of course. German word is: Wickelfeder Spiralkabel btw.

38:32 What's the blacked out bit?

Other idea: Put magnet on that wiper and it will move over small levers that will close contacts. Wiper can be on threaded stud and move linearly. Levers must be plastic with small metal part to attract magnet. With smart mechanism you can even omit unintended connections and only lower magnet over the required contacts.

damn this boehm soundlab is looking so nice.

Maybe don't use rotary switches, but linear ones and use off the shelf carbon brushes with spring brush holders? Might need some maintenance but seems a more sensible design for DIY?

No way you pulled up a synth! I can only imagine how much you've played with those. You made my weekend and brought back the excitement I had as a kid for electronics!

I have several metres of Tellurium Copper round bar in my metal store, and a brand new CNC mill. Now I want to make some motorised switches like that gorgeous rotary at 08:17 instead of what I am supposed to be working on. You are leading me astray again!

I like it that you chose to re-use the SCPI command syntax 😉

Could you selectively electroplate copper on to the plastic pieces with a suitable seed?

It would have worked better if you used oil my friend

You could deal with the potential of shorting intermediate configurations while turning if you made one switch that turned all of the front panel connections on and off at once. A modified version of your rotary switch, with individual input and output pads, then a stepper motor with a multiple-wiper fixture on it, to open or close all of the front panel contacts at once...
