Yes I'm aware of the legal,ethical and moral implications of the technology future ahead.
We already have supercomputers or quantum machines that can outdo the human intellect on many levels.
At $20 million per computer, they're a bargain deal prices to major corporations.

Imagine if such a machine where assigned arms(satellite laser weapon) to issue varying pulses of pain at the individual person level,
what sort of world can future generations of children look forward too?

How long before the quantum computer(s) become self aware and decide that it's own creator(s) are a threat to its very existence?

I remember as a kid laughing at comic books and reading about Buck Rodgers style laser weapons. And now comic book laser weapons are reality...

Met this guy a week ago. So a B36/42 can be good for something!

I am afraid that we have only seen the tip of the iceberg when it comes to the pittfalls of AI. How many movies in the past have we seen " out of this world " ideas in advancement of tech in the world..... and NOW some of those ideas have come to fruition? Far too many possible quirks could really bring the issues to light....

Hi...i would like to share my stuff also. I made an automated tea infuser. It uses the two Canon primary wire cleaner motors and two DPST switches to drive Mita lens reduction gears. It drops the mechanism into two teacups then cycles once per second vertically 40mm. I wanted to be able to preset a timer in which the machine would retract from the cups, but never did figure that part out.

Stealing someone else's post and using it as your own. That's a new low. WTF is wrong with you? Go away douchebag.

Have you ever heard of Arduino?
With him you could do many interesting things.

Yes been using it. The C code is sometimes a little tricky for me but getting there.

Here is my take on a pen plotter. 3 Lexmarks died for this, what a good day.

Allan! Dude, that is awesome, kinda like the idea to do such cool things, just because you can

Well done. I'm jealous....

I would like to do the exact same thing. I have fully designed a 3rd router machine from the ground up, I have motor driver boards ready to build, but I have been too lazy to get in an do any more...

Instead of C++ have you had a look at G-Code? A lot of CNC machines use G-code. A few CAD programs convert to G-Code as well.

It looks like you've designed built the machine from 3D printed parts.

Congrates to you...

PS...
Would luv a peek at your adrino setup.

Hope to get into the Arduino stuff again soon.

Started by wondering how to use some of the parts that comes off from scrap machines.
Some of these stepper motors could be as much as $80 if you need to buy them.
The first CNC thing i made was one of those mini CD ROM machines that use a servo for the pen lift.
That used 2 L293 chips to drive the motors and was controlled by an Arduino and a dev platform called "Processing 3" that fed the gcode line by line.

This machine has no torque and can do anything else but wow those tiny motors run!

Jip its an industrial class controller check out LinuxCNC distro or Mach3/4. LinuxCNC is not limited and completely opensource.
Fusion 360 CAM is awesome and the included post processors allows for almost any kind of machine.

Would like to see you get your router running.
What do you use for CAD?

Sounds like the go...
Post some URL's about the Linux and Fusion modules etc....

Re. CAD.
I'm familiar with a couple of different setups AutoCAD R12, RhinoCAD, Solidworks, TurboCAD...
I very much prefer Solidworks CAD,but I can't afford the $17K-$20K price tag for home use, so I use a cheaper $300 TurboCAD system.

I don't know if you're familiar with 3D modelling or vector graphics, but TurboCAD allows for fully programmable parametric parts. Once a 3D part is converted to parametric you can treat that 3D drawing as an object. You can then drag-n-drop that object onto a new or existing model work space. You can then quickly adjust the X,Y,Z factors of the object to fit the new model or drawing. Parametric objects are time consuming to first set up but are far more efficient in the long term.
Similar to Solidworks ,TurboCAD Parametric parts are a very efficient fast way to model 3D CAD works ready to send G-Code to a CNC machine.

Know Solidworks really well use to have access to it, loved the ability to create configuration tables using excel and the linked dimensions.Sheet metal was a breeze. But like you mentioned its super expensive.
Downloaded the free 30 day Fusion 360 trial and applied for a free hobbyist license and now its activated for personal use! Its not as intuitive as Solidworks at first but you grow into it. CAM side is brilliant.

For the 2D CAD try Draftsight from the creators of Solidworks its free. Had Solidworks installed and uninstalled on my PC since then it does not run.
Found nanoCAD also free to use and works really well.

nanoCAD - Cost-effective CAD Software for DWG files and 3D CAD/CAM Design Software. NanoCAD - 3D Design, Engineering CAD CAM Software for DWG

Re. Solidworks bug.
A few years ago an engineer associate loan me a version of Solidworks 2006. I could never get it to run properly as it would just stop working for no reason.

TurboCAD has a full very detail parts database and Excel spread sheet interface. It allows for bill-of-materials and materials schedules directly into every CAD drawing.
Comes in handy when you want to see a materials schedule printed directly beside the drawing or attached as an addendum at the back.

----update----
I checked out the solidworks URL you sent. I see that Solidworks company is providing a student version of Solidworks. I email them years ago for a similar student version of their product, but they wouldn't enter into it. Good to see that their company is offering a student version. They finally realized the more people who can use their Solidworks products the more they make in sales.

Realize how much i suck at taking videos and photos...
One way to skin the circuit making rat.

IC 555 single button on-off switch with reed relay for output.

To be running LED circuit using IC 4017. Just for fun to check the development process before the micro controller stuff starts.

The first circuit i learned 20 years ago! The mind breaking astable multi vibrator that in idea theoretical condition is not suppose to work.
What determines the first transistor to bias? The travel distance of the electrons?

Really need gloves for this ferric chloride stuff.

Re: Electronics

New tricks learned.

Circuit Maker by Altium. Well worth the pain of the learning curve, understanding DRC (design rule checking) almost had me crying.
There must be easier ways to get boards designed but this is as close to industry standard software as i can get without paying a fortune.
Then there was FlatCAM straight forward awesomeness free to use by one Juan Pablo Caram.
CAMotics for G-code simulation is great to get a preview of the paths and speeds and saves a lot of time to verify files before execution.
