- ChrisWx commented on knaylor1's instructable Photoresistor Arduino Midi Theremin
A photoresistor is an analog device. It changes resistance based on the amount of light it is exposed to. A regular PC has only one "analog input" - the microphone jack. While you could, with a lot of experimenting, make a circuit that would connect a photoresistor to the microphone input, it runs the risk of breaking your computer if you get it wrong.The pad/midi thing is not needed. The Arduino plugs directly into the computer. The Arduino is basically acting as an Analog to Digital converter, which reads the positions of the knobs and fader, and converts them into MIDI messages. It does the same for the photoresistors - sensing their resistance and sending a corresponding MIDI message when they change (I'm guessing here - not associated with the OP).Coding can be easy a…

Are you related?
View Instructable »As others have said, there's no way that arrangement will be able to 'roll' side to side. The two servo stacks would prevent each other from rotating in that direction (unless they were strong enough to break the board). Also, why two joysticks when one could do everything needed? You must have tested it before publishing. Maybe focus more on engineering and not how cool it looks.

The title says touch, which implies touch activated, but it's two buttons, which means the title is clickbait. And the thumbnail picture is a do nothing circuit whose only relation to the project is similar parts, so also clickbait. Please be a little more honest with your publications.
- ChrisWx commented on BreaksnMakes's instructable 3D Printed LED Mood Lamp
For this low power, that's probably good enough. But you could add some holes in the top for a bit more circulation and convection cooling. A decorative pattern might even project onto the ceiling. If you do, remember to leave the top removeable, so you can dust it out once in a while.
I'm not the author, but I believe I understand his reasons. The main reason is a typical USB 'micro B' phone charger only supplies 1 to 1.5 amps - not enough for this. The supply he used is 36 watts, which would be over Seven Amps at five volts. Sure, some USB chargers can supply more than 2 amps (and more than 5 volts), but you'd have to specify a particular kind of charger for it, and those chargers need a USB port configured in a special way to tell it it's okay to supply more power than 'normal' USB can. This project could easily be converted to USB C PD. USB Power Delivery can be configured to deliver 12 volts at 3 amps, just like the supply used here. But though the USB PD "Trigger" boards (would replace the buck converter here) aren't expensive, USB PD capab…

If you use the Gemma M0 instead of the Trinket M0, it will fit in the middle of the Neopixel ring. It's even the exact same microprocessor, so you wouldn't even have to change the code, except possibly for the Data pin number. This would leave space for a small Lipo battery and a the MicroLipo USB charger. A 500 mAh LiPo battery would let it run cordless for hours.

That sounds like it would work. The whole idea of the ball in the can is to re-mix the propellant (and possibly thinning agent) with the paint. Since they separate by gravity, and the ball has to travel through the layers to assist in mixing them, shaking along the long axis while holding the can at least partially vertical, is much more efficient at mixing everything.

- ChrisWx commented on Donald Bell's instructable VK-01 Off-World Bartender
I love the appearance. Something I always wondered - Do you have to be careful about the height difference to the nozzles to prevent leakage from the pumps? For the next version, I have some suggestions: Make the nozzle plate thick enough to put 90 degree nozzles in there, so you can run the tubing straight back inside the arm. Cheaper microcontrollers could replace the Huzzah and ItsyBitsy and use SPI to talk to the Pi. A Pi can talk to four devices over the same SPI bus. 33k resistor and a 10k resistor in parallel is about 8 ohms. A single 10 ohm resistor could replace them. If you'd rather stick with wireless, consider a plain 8266, they're a bit cheaper than the Huzzah. Sorry that's so mishmashed, but I was in a hurry...

Very nice. But the link for the standoffs is empty, and the only places I can find them want upwards of $10 each! Since they're not being used as standoffs, it would be much cheaper to use actual LEDs or even LED strips. Is there somewhere else to get the standoffs cheaper?

To assist in removal, if the back of the original part is fairly flat, place the original on a long piece of "duck tape". Flip the ends of the tape over onto itself to give you some 'handles' for later, leaving some sticky space between the end and the part, then powder the tape (as well as the part) so it won't stick to anything else. When the clay is all pressed in and ready, use the tape to carefully lift the part out of the clay.

Excellent article and project. I can't believe you fit that battery in there! I also can't believe you got it all working with that 4.5 v requirement! True engineering. Of course, other people duplicating this might have issues, as some parts might be slightly out of spec in the wrong direction. But there are many 3.3 v microcontrollers that are fully compatible with the Arduino programming environment. The STM32 series is very well supported under Arduino. The STM32L0 (That's a zero on the end), for instance, could probably be subbed in with very little change in code.

Second the video request! But also, though I've never seen it done, Sapele is a dense hardwood that mimics the color and somewhat the appearance of a darker mahogany. It's very stable and it's density would, I believe, make it a good alternative to mahogany for a fretboard/fingerboard. Best of all, it's a very popular wood for doors and windows, so if you have a large window/door shop nearby, you should be able to get some scraps from them very cheap. (Like most woods, some pieces are harder/denser than others. Pick through the scraps and find the heaviest one.)

Couldn't this be solved with a PVC ball valve? Drill the right size hole in the cap (toward the front edge, so the tree it's attached to won't interfere with filling), glue an adapter in the hole that will fit a 1" PVC valve, then put a cap (no glue!) on the open end of the valve to keep dirt out. The valve alone should provide a good seal, but the cap will help out just in case. I admit that it would only be economical to fill the watering station when it was close to empty - otherwise any extra water in the pipe when you open the valve will just spill out.Take a small section of left over 4" pipe, put a cap on one end and glue in a female fitting that fits the other end of the valve, and you have a 'Funnel' that stays put when you fill it.

Regarding the water comment - energy cannot be removed from the system. Water would slow the spin induced by the sling, which would affect wind resistance and accuracy, but wouldn't affect the tuning of the trebuchet at all - since tuning is what you used it for, not the competition, it's perfect. With such a short time of flight, the effect on distance would be barely measurable in any case.I would Love to experiment with this design. Some kind of mechanism to fine-tune the finger angle for release time would be awesome. From the slo-mo vids, your release angle was, as close as I can tell, a perfect 45 degrees - great for distance. I have to wonder what it could do regarding projectile speed with a later release. Wouldn't get the distance, of course, but it would pack a mean punch …

I'll have to agree with several other people about the encoders, but why pay $30-hundreds of dollars for the hi-res ones? If you're going to 3-D print the mount anyway, go ahead and print some gears! Better yet, since gears can have a little slop, a toothed belt, used in some 3-D printers, works better with less hassle. If you need more absolute position data, use both! Let the analog pot be your rough position indicator, and let the encoder do the fine positioning. That dithering or noise that analog pots do lowers your resolution, so use the encoder for the final 2-4 bits. If you use it in quadrature, meaning you sense all four level transitions, an encoder labelled as '24 ppr' can give you 96 increments per rotation. It wouldn't take much gearing to get that up to a usable level.…
