I didn't and I was pleased with the results, and couldn't hear anything wrong with the effect. However, I suppose you would get a more pure signal if you did.

Very gently lift up the capacitor and see if there are marking on the underside. Some multimeters also have the ability to read capacitance. You could also try Google image searching for "Land Camera schematic."I'm guessing for the electromagnet that you can apply 1V - 4.5V to the spot on the board where those wires are connected. Start with the lower voltage and slowly work your way up. In theory, the magnet should magnetize and stick to things at a low voltage, albeit, it might not engage the mechanism.

Nice one! I would need a bigger apartment though if all my tools were this size. :)

I've made a partial update to the list of upcoming contest. We are still shuffling the calendar around a little bit. Stay tuned for more shortly!

I can't check what my shutter looks like on the inside because I have film in it. However, I took a picture of what it looks like from the outside.You should be hearing two clicks. One when you press the trigger, and another when the shutter closes. As you mentioned, a good way to force the shutter to stay open is to cover the light meter with your finger. On the first click, the shutter should open, and when you remove your finger, on the second click, the shutter should close.If the shutter is not opening, you have a problem that I am honestly not 100% sure how to debug. That said, the first thing I would try is to make sure that the battery is new and that all of the wire connections from the battery to the circuit are good. Beyond that, I don't know what to do.

I've read that it is the timing capacitor that corrupts on the circuit board for these cameras. So, it is possible that might be the issue. You should be able to tell whether or not the solenoid / electromagnet is working by briefly applying power directly to it.If the mechanical shutter is broken, I am not sure how to fix it.

That's a good thought. It has been a while since we have done that. I'll add it to the ideas list.

I see. This seems to be a popular request lately!

Check out the schematic on the bottom right corner of the image on this page:http://www.all-electric.com/schematic/simp_mix.htmBasically, you put a potentiometer between the two channels and put the center pin to ground. Their schematic uses active components to do the mixing, but I don't see why this method should not work with a passive mixer such as the one in this Instructable.

I'll post an update soon for the next few months. We are currently reworking the contest calendar a little bit.

I would agree that it is not in the spirit of the contest. We wouldn't let a hamburger-shaped pillow into a BBQ contest. It is a "home" contest, and not a scale model house contest. You have to plausibly be able to live in it.

I'll add it to the list of potential ideas. This one might be fun!

That is definately in the realm of possibility. I'll add it to the idea list.

We haven't always had the best turnout for instrument contests in the past, but an audio contest is likely on the horizon, and we would love to see instruments in that.

I'd love to! I think I can win it! I'm not sure the powers that be will allow that though... :)

And you're using the amplifier jacks and not the audio output pin? Have you adjusted the volume using the volume pins?

Mine was plenty loud. Have you tried using the board with a different speaker or a different sound clip? Did you test the board before installing it in the project to make sure that it works?

Yes.

Those are basically the difference. The size of the prize and length of the contest.

Woah! I had no idea that you actually did raise the dead!

Nice! I like your 3D model for this.

Where did this project come from!?!?! Did you dig it up out of the ground?

No. Unfortunately not.There is this forum topic about the contest changes though:https://www.instructables.com/topics/Important-Cha...We've been doing better about announcing important site changes over the last few months. Unfortunately, as you have discovered, there is currently no place they are indexed, and the forum search is admittedly not the best (as it currently stands). I have put in requests to improve both of these, but there unfortunately currently is no timeline that I can offer.

Nope. 1 project to 1 contest. It does not matter if the contest it is in closes.

The file is there. It just appears this site is unable or unwilling to process it. I have reported the bug.Here is another site that has the clip:https://archive.org/details/GroundhogDayRadioAlarm

They delay function is in milliseconds. That means for every 1000 increments, the program will wait one second. For instance delay(2000); is the same as telling the code to wait for 2 seconds.You would engage the function to turn on the motor, delay for 10 seconds, engage the stop function on the motor, create a delay for 300 seconds (5 minutes) and then reverse the motor (and then stop it again).

The file is in Step 8. If it changes the filename to a radnom string of gibberish when you download it, rename it to T01.ogg

Thanks for pointing this out. That should not be allowed. I will investigate.

I normally just buy ghee from the store, but it is super cool that you made it! I bet that came out really good.

Thanks for the suggestion. I don't know if there is enough paint-centric projects to justify a whole channel, but I will definitely look into it. My gut reaction is that there are a lot of projects that use paint, but not as many where paint is the central focus.

Nice build! I wanna build one of these so bad. Some day when I have easy parking.

Are they entirely gone, or just clipped? If there is enough wire to work with, it should not cost much at all.

When I was making this project I couldn't find one like that wide enough to provide enough surface area for the velcro. That is why ended up going with the adapter.

It depends on the voltage requirements of the motor. Different motors have different voltage ratings. However, the shield has a maximum voltage rating, and I would not put more than 12V through the shield. Although, your motors might require less voltage than that.Supplying the right amount of current is important. You would want to make sure that yours motors do not draw more current than the shield is able to handle. I would not exceed more than about 2 amps per channel. Also, this shield is a dual H-bridge, meaning it can only control 2 motors.

It wouldn't be ideal. You would need a much slower gear ratio. Most drill spin way too fast, even with speed control.

Nice! Glad my project in some way inspired this! :)

Nope. The camera spinner was just a step towards a different larger project, so I was more focused on the video aspect of it. I'm also really bad at thinking of practical uses for the things that I build.

This would be a little tricky because it would require connecting and disconnecting from each camera's wifi network (as needed), but totally doable!

Perhaps you missed the earlier discussion:"I often wonder about that. I think it boils down to the fact that they are just insecure about their own projects not being nearly as good as the thing that I have posted that they perceive as useless. It is basically just an overestimation of their own abilities, and underestimation of mine. I just wish they kept their pathos to themselves. It's unbecoming."Anyhow... goodbye comment.

We will run one again eventually, but I don't currently have it scheduled.

Underwater is too specific, but there is a Water Contest launching tomorrow!

I often wonder about that. I think it boils down to the fact that they are just insecure about their own projects not being nearly as good as the thing that I have posted that they perceive as useless. It is basically just an overestimation of their own abilities, and underestimation of mine. I just wish they kept their pathos to themselves. It's unbecoming. Anyhow, I also built a machine to make these kaleidoscopic videos that if you watch for a long time will really through off you off. Stare it for a while, and then stare at a fixed object. The object will seem to keep spinning for a while:https://www.instagram.com/p/BZZrwkElWzU/

Not offended. I just got a lot of comments calling this the most useless thing they ever saw. I was just happy to get a reasonable response asking about why I wanted wanted to do that. So, I decided to explain myself.

Second question. How would you like if someone said that on one of your projects?

I thought about adding another sheet of velcro with a bolt and some fender washers inserted through the middle to offset the weight, but ultimately didn't fuss around with it.Instead, I decided just to build another better balanced machine.

Sell the scrap metal and buy a better drill.

Lately, as part of my art practice, I have been building machines which produce video effects using different optics and motions.Basically, I just wanted to see first-hand what happens when you spin a camera very fast. This was a very quick way to get there, and figured I would share it in case anyone else was curious.I'm currently building a much more refined machine for making video portraits in a similar manner.I'm not really sure why everyone is so upset over this project. There are much worse things in the world to be upset over. However, I guess I rather people be upset enough to respond than not respond in any way at all.

I have not tried that, but I don't see why not.

All-in-all I think I spent somewhere in the ballpark of $300. I built it about a year ago, so I don't remember 100%.

Target. But I am not sure they sell them anymore.

All of the parts are linked to. I got them from McMaster. I'm guessing all-in-all this cost me a few hundred.

My workbench is very heavy and his the bottom crossbar pinned up against the wall, but it would be a good idea for a lighter desk.

Thanks!

Thank you. Has been working out really well for me.

We have added a "Game Life Contest" to launch in July. I think at this point the summer contests are pretty locked down. We are still finalizing the lineup for the fall, so it is a little bit premature for me to post those. Expect an update about that around the beginning of August.

I would think regular milk would work fine. I would consider perhaps using heavy cream or half and half.

Fahrenheit

I wish I could bring some in July. I have so much ice cream in my freezer.

Tell me about it! This project was originally sponsored by Radioshack (RIP) and the video they made to go with it didn't showcase the drums at all!Here is a not-so-great video of the drum kit right before I sold it and moved across country:https://www.instagram.com/p/94zVc_EaJm/And this is a video someone took when I was first building it and working out the bugs:I really wish I had a better video of this thing in action!

Thank you! :)One of these days I will live in a place large enough to hang it up again.

What are the sensor values that show up when he opens the Arduino's Serial Monitor?What type of speaker are you using?

I'm not sure I follow you.

Yes. Indeed.

My gut reaction is that it sounds difficult to figure and the lenses are probably expensive. Not sure this will do anything at all, but have you tried sticking a a camera lens backwards between them?
