Let's see your finished DIY projects!

Very cool. Any cooling fans or anything? Looks like a good build

no, just some venting holes. It barley warms up, but I'm also using it with a solid state head.

Not a pedal, but still a pedal related project, and def diy....

I am trying an experiment to automate some machining operations on a cnc. The first step is to try to make a vise that can be opened and closed by the cnc software. I bought these air cylinders but was not sure if they can hold the workpiece firm enough while cutting. so today i test that a bit with this DIY vise jig. It seems to work very well. For now i just open and shut it with a dc supply manually plugging it in and out, but a relay could do the same.

Old manual vise system:


New test vise:


Jaw for "125b"

Rad!

Do you have a different jig for the larger enclosures?

[multi_s]

not for the auto vise yet but ya for the manual vsise we have many jugs for holding different cases in different poses, to do the side holes etc. my camera just ran out of batteries but i can post some pics of the other jigs later if you want. just different jaws basically.

That's awesome! Any ideas how you could automate removing a finished enclosure and loading a new one in?

I just spent ten minutes watching robot fail videos looking for a witty response.

Nice work multi_s!

yes actually i am trying to make a cheap robot arm to remove them or come up with a method using more cylinders to push teh cases in/out, im not sure what is better to develop yet.but basically i was inspired by this animated gif of a 3d printer facility, although with smaller arms mounted on each cnc, not one big arm servicing an array of amchines, mostly becaue the machines are too big and the rm would have to be huge. but this is the idea more or less.

although even having arrays of auto vise will speed things up a lot. just ordered parts to make 6 more vise so i will try to post a video when it is actually used for production.

the thing with the robotic arms is it seems hard to get anythig that can lift a few hundred grams even for less than 1k+. Since i need a lot of them this is not a great option and actually huge surpluss robot arms that can lift 200 kG are available used for only 5-8k so spending that much on a bunch of toys when you could get something that could build cars seems a bit ridiculous.


if you lookup the original "dobot" kickstarter which they said would be open source, i will try to copy that style arm but make the parts in house. in the end it doesn;t look like they made the dobot project open source even though it got funded (lol) but the original model does not look that mechanically complex.

edit: also if you are looking for a pretty bad ass diy robot arm for fun or whatever this is probably the most impressive thing i found, the guy is still dev'ing it but the videos are coming out with progress every month or so. his goal was to make it all with cheap 3d printer + parts form amazon. pretty nice results id say. for me i only need 4 axis maybe not 6 so i will make a simpler arm to save money on motors. but this guy has probably made the most impressive open source arm i have seen yet.

So the real takeaway from that gif is you'll need a lot of LEDs

The "dobot" looks like the perfect general form factor for this kind of thing. I'm not sure you'd really need a spherical arm or a bunch of joints to control end effector orientation. This is awesome man, I'm excited to see more!

Here's a Bee Baa, board etched from RG Keen's layout on GEOfx. Sounds fantastic!

SO AWESOME! I love your enclosures so much

[BetterOffShred]

I already commented on it, but I'd just like to reiterate that it's super dank. I love it too!

Thanks dudes!

I built a Wolf Computer from EATYOURGUITAR's modified schematic. he didn't have any pcbs left so I did mine on perfboard. next time I'll use vero , there was a lot of stuff to troubleshoot and I hate trying to solder down component legs as circuit tracks!

it sounds pretty crazy. always wanted to hear one of these things after reading about them so much on here over the years. this one's for a friend but I'll have to build another sometime for myself!
