Sorry, just seeing this. You likely want a latching switch, not a momentary. This is easy to swap out.

Thanks!

By changing the position of the bolt attached to the wheel you can draw tori of different sizes. This changes the ID and OD, and thus the surface area it takes up on the paper. Students can calculate the difference in surface area. It also demonstrates translation of motion from rotary to reciprocating. You can also calculate the width of the torus based on the rotational diameter of the bolt attached to the wheel. What subject and grade do you teach?

Nope

Says the maker of the glowing floating faucet... :)

The potentiometer definitely needs to be grounded to a ground connection on the circuit. Also, make sure that you have the polarity correct on the capacitor.

I am not sure. Those connections look correct. Maybe the value of the potentiometer is different...?

Anything 5V or less should work. For instance, a USB charger (or similar).

I wish I could take credit, but this update was courtesy jessyratfink

Here is one I made while testing:https://www.instagram.com/p/BxlubuQljkt/?utm_sourc...Perhaps I will make a better one eventually and put it in the Instructable.

I bought an industrial foot pedal that the whole thing plugs into and power it on and off with that. It's hanging up in my living room with the foot pedal beneath it. Extending the chain is another good and simple option.

That is not great. Let me see what we can figure out.

I am not 100% sure, but it seems like the 50 ohm resistor is there because the potentiometer can get into a state in which there would be no resistance on that side when turned all the way up. The 50 ohm resistor makes sure there is always a little resistance on the mosfet pin.

Nice! One of the first electronics projects I ever built in college used an SPO256 chip. I had it saying some ridiculous things. :)

Nice! Thanks for sharing. :)

This is really cool. It's better machines are left to this task than myself. :)

Cool project. I think it would creep me out a little to have this watching me. :)

Clever solution.

Well... let me know if it that fixes it or it keeps happening. Honestly, this should have been fixed a few weeks ago and (after some investigation) this is the only known instance of it being reported since then.

Yes and yes. You can swap out a lot of the parts to get different kinds of fuzz effects.Check out these pages:http://home-wrecker.com/multiface.htmlhttp://web.archive.org/web/20050513200126/www.geocities.com/tpe123/folkurban/fuzz/fuzzyfaces.html

What browser are you using? Are you getting any particular error messages? What is happening before you decide to refresh things?

It does not appear to use static electricity. These fans can be run off of a 9V battery, so it presumably uses fairly little current. I would say 12V @ 0.5A or greater should work.

The wire going into the PVC is actually a 2-wire cable (presumably coming from a 12V DC power supply with the end cut off). You would need to split the cable in half and strip the ends of the two separate wires. It is hard to tell in the picture above. See attached for a crude diagram of the circuit.

Sorry to hear that. What are you searching for?

The CNC Challenge was moved to September and expanded to be a full contest. We will be updating this page very shortly with the tentative schedule through the fall. We're just ironing out a few last details.

There are a few more minor things we need to pin down before posting a full update, but hope to have it up shortly.

You should start a new forum topic to ask this question. I am not sure you will get much of a response on this topic.

Are you still experiencing these problems?I can see that you have cleared your cache, but have you also tried clearing cookies from the last few days? Sometimes when I am viewing the site during a release I will experience strange errors and need to get rid of both.I was not able to reproduce it.

Soon. Check back next week.

The pot is being used to adjust the resistance on the emmiter, and therefore only two pins are needed. You only use the third pin when you want to create a variable voltage divider which adjusts the output voltage of the center pin. In this case we don't need it.

Theoretically, yes. One way would be to replace the potentiometer with digital potentiometer ICs, and have those controlled by an Arduino. You can use the Arduino to interface with any sort of sensor or controller.

I suppose I hypothetically could, but I'm probably not going to build one. :)

A premium membership allows you to download PDFs of the individual projects. There is no access to additional content with such a membership.

It can be anywhere from a few minutes or a few years. Featuring is subjective to the person(s) who are looking at the Instructables as they come in. A lot of different people on staff with different perspectives view Instructables, and sometimes the feature-worthiness of a project may be overlooked. We try to catch as many as we can, but sometimes things slip through the cracks.

Cool project!

You can create a new forum topic here in the community section and ask for help.

I link to a part on Jameco. It is listed as being discontinued, but they have 197 still in stock.

We unfortunately don't currently work with any new outside prize suppliers.

Was this for a school project?

Is this for an engineering class?

Out of curiosity, were you required to use Fusion 360 for the class, or something you decided on your own?

That is not really a problem solved by this Instructable. The way I think you would want to do it is to plug it into a Raspberry Pi, and have it run a script which reads out loud the keypresses using pre-recorded audio. And then, the script (pretends to be a keyboard) and exports a keystroke command on to the next computer (assuming you ultimately want to show this on a computer screen).You could also take a similar approach with an Arduino, but it may be a little trickier and require some additional hardware.

I love the look of the body and the attention to detail! Very nicely done.

Cool. Thanks for sharing.

Wow! You really did it.

You should post the picture of the one you made in the last step into the intro. It looks a lot better than that screengrab from your phone!

Does it matter if you use different color LEDs or different types of LEDs?

Nice. Just in time for spring.

It looks like you are feeding your pets m&ms.; :)What software did you use to design the 3d parts?
