"The Romaurie-Effect"

I have been using refrigeration compressors for many years as vacuum pumps. When I started in commercial/industrial refrigeration some 30 years ago, all the engineers in "Prestcold" Bournemouth branch made their own small portable vacuum pumps from discarded domestic refrigerators. It almost appeared to me, a newcomer to the industry, a competition of sorts to make the most practical/aesthetic unit possible.Some engineers made varnished wooden cases to house the compressor. These were ideal for all small refrigeration vacuuming requirements. My interest over the last few years has been to use these "home-made vac-pumps" to produce vacuum filled inverted aquaria. "The Romaurie-Effect" as shown on "youTube".This is an on-going project.

Is there a sound effects machine?

Is there a machine or something you can make where you can plug in sound effects files and then as you push different buttons it will play the effects on cue? I have been searching and can't seem to find anything. Thanks for the help.

What effects are in this song? Answered

In the song "Barely Breathing" by the Hold steady, lead-singer Craig Finn does something interesting with this voice at around 0:19. After watching live versions of the song, I'm pretty sure it's post-production. If it  actually was a series of pedals, how would this be achieved? To me, it sounds like reverb with delay. What do you think? Thanks, Noahh

Blender cool effects

So I really like the program blender. I enjoy using it, but I am not very good. I thought it would be cool, though if there was a place where people could share cool effects they made in blender, so this is the purpose of the forum. If you made a video with a cool effect in blender, post it here or link it here, I would love to check it out :D

Effects of Inductors Coupling?

This is a follow up post from this thread >> https://www.instructables.com/community/Guitar-Wah-Wah-Pedal-Help/ (It was about how to fix my Wah-Wah guitar pedal, it turns out the Inductor was not working, so I replaced it) I replaced a broken 500mh INDUCTOR in my guitar pedal with a new one. It works now. However, I am planning on keeping the broken inductor in my wah wah pedal (because it yielded a cool volume pedal sound). I want to rig up the circuit so that I can switch from from the GOOD conductor to the BAD conductor. My questions are: Will there be any major effects from having two inductors coupling? Should I be wary of the 'winding' of the coils? If so, what should I do in order to be consistent with the winding? And out of curiosity, how could I rig this up?  Here is the schematic >> http://www.voxamps.com/downloads/circuits/wahwah93.jpg 500mh Inductor = L1 I have 3 terminal DPST switch. This is how I imagine rigging it up: I'm thinking of having wires from the inductor terminals on the PCB wired to a terminal on the SWITCH, then to the INDUCTOR, and then back to the PCB. The same follows for the other (bad) inductor. If this is not clear, please let me know, or feel free to post a better way to rig this up. In summary for this last question How could I rig this circuit to switch between two inductors? Thanks.

sound effects modules

Hello!! I am planning several Halloween props that will benefit bigly from sound effects. For instance...I'm working on a mantel version of the demonic grandfather clock in Disney's Haunted Mansion. It would be awesome to have the sound of the ominous ticking, backed with a chime, that the "real" clock has. This could be an audio loop of just a few seconds. Some of the other parts of my scheme would be enhanced with short loops of sound effects or mood music...a minute or two at most. I don't have a background in electronics, but I can follow directions. Any advice on constructing a few, small sound effects modules? Thanks!!

Calculating heating effect.? Answered

I have been experimenting with making a hot wire foam cutter. This needs to be at least 600 mm wide. I have to hand a PSU capable of providing 14 volts at 2 amps (or slightly below) This is 28 watts. Now the question i would like to calculate the heat the Nichrome wire will reach at any given wattage but have no idea if I can do this. I have several wires that work to different levels, resistance of 30R, 4 R, 137R at the length I am using. Any one any  ideas how to calculate the temp or are there too many variables? So far I have worked empirically and arrived at the conclusion I need either around 18 volts at about 3 amps or I need a wire with a resistance of around 7R to suite the power i have available. I do know that the 20+ watts I am generating is just heating the wire to the melting point of the polystyrene foam. The melting point of the foam is apparently around 220 to 240 deg C (internet) At present it isn't cutting fast enough for my project. which required producing 5 mm thick sheets of foam with a reasonable consistency. i am cutting them from a 50 mm thick 1000mm x 500 mm block.

How does the Bernoulli effect affect the ground effect?

I have been wondering about how ekronoplans work with consideration of the Bernoulli effect. Ekranoplans such as the Caspian Sea Monster often have there engines or propellers pointing on a downward angle, this is to push as much air under the wings as possible, in doing this they are forcing the air into a constriction being the wing and the ground, now why doesn't this cause a vacuum pulling the craft down?

Create standstill effect with LED from hall effect sensor ?

Hi everyone, A little bit info of what I'm working on. I am trying to create a standstill effect of the spokes of the car rim. I attached a hall effect sensor and a magnet to inside of the rim . I have tried 2 different approaches : ( code for each method are also attached)              1. use the hall effect sensor to determine the RPM of the rim and then flash the led accordingly to the spokes on the rim. The problem with this approach is that the led flash quite dim and and the spoke image rift.  I cant find the right windows for flashing LED.               2. use the the hall effect sensor to detect any magnetic field and then flash whenever it is detected. This method is quite simple but the effect is blurry. The problem for this is that the magnet detection happen on the arc of the rim instead of at 1 pin point location. Hence the led is on for too long --> blurry effect. I also attache some diagram to explain my problem in case I didn't do well with words.  Do you have any suggestion, solution or comment on the approaches or the code. Please feel free to throw in. Im all ear.  Code:  Method 1: Calculating RPM then flash led : http://txt.do/5b9is I am leaning toward this method but the effect is rifting. Not entirely sure how to fix it or what could possibly cause it.  to clarify: the rifting effect happen when i use 2 magnets on the rim. with only 1 magnet, it still rift but the led very dim, almost unnoticeable.  Method 2:  Image for the 2nd approach in case the pictures didnt show on instructables the front : http://imgur.com/HwFm1lT the back : http://imgur.com/1DvWjZK the side : http://imgur.com/RHZIbfR The problem : http://imgur.com/RHZIbfR flashing LED whenever sensor detect the magnet: http://txt.do/5b9b7

how effective is this airflow design? Answered

I am working on a very small build pc, and i was thinking that the best way to reduce overall height would be to design a cover piece that directs the airflow from the intake fanover the CPU and northbridge heatsinks and out the back of the unit via an exhaust fan. this method was chosen because the fan cannot be on top of the cpu heatsink because the unit would be too bulky if it was. I have attached a crude image of the planned cover and the layout of the board's heatsinks, and i would like to know if this is a effective method for cooling, in such a small form factor. if it isn't, what is?

electromagnetic pinch effect demonstrator

Greetings, Instructors! I've done some searching in the Technology section already, but (as you know) it's huge, and I didn't see anything that was close enough to what I'm looking for except the electromagnetic coil gun. I want to replicate a demonstrator I saw, once upon a year, at the Smithsonian Institution. A thin-walled metal tube was dropped into the spaces inside two stacked, separated coils, as if it were an axle for a pair of wheels. A brief, large current was then run through the coils; the induced currents in the tube produced the "theta pinch" effect, crushing the regions of the tube that were within the coils. (The machine was set up to sell the products for a token price; the impressively crushed tube was dispensed as a souvenir.) I need advice on the type and capacity of capacitor, thyristor, power supply, etc. to employ. Has anyone here built one, or know someone who has? Thanks!

Calcium Chloride Corrosive Effects

I know that calcium chloride can corrode metal, but does it require direct contact or can it generate fumes that could corrode?   Here's the issue:  I have a wood stove and I place a container of Damp Rid inside over the summer to absorb moisture.  It looks like the Damp Rid plastic container had a small crack, so moisture passed through the calcium chloride and through the container and through the back of the stove After a while I noticed a pool of water behind the stove.  I traced the problem back to the Damp Rid container, cleaned up the moisture inside and outside the stove, and replaced the Damp Rid.  At the same time I noticed areas all over the exterior of the stove where the finish was coming off, areas that were not in contact with the water.  In fact, at least one section of the stove that had direct contact shows no sign of  a problem. I'm trying to discover if the calcium chloride caused the problem, or if it's something else causing the damage.

How could i produce fake steam/smoke effects for a steampunk costume?

I am in the process of making a steampunk/mech themed costume for an upcoming comicon. As the centerpiece for the costume i am trying to make a literal chimney tophat which i would like to emit steam or smoke or something similar in appearance from its open top. I need some kind of gadget or means to produce the desired effect that can be fixed inside the body of the hat. It needs to work in a safe manner and be compact and lightweight enough to wear inside the cylindrical part of the chimney hat just above my head. As a back up, in case i cant find a solution to the above problem in time, im intending to hack a bubble gun and use that for a stream of bubbles but i would prefer to have a means of producing a relatively convincing stream of fake steam/smoke. Any ideas are appreciated thanks... P.S. im not sure if this should be posted here or perhaps in 'science' so apologies if i posted in the wrong area

Walking/Marquee effect for LED Strip

I'm trying to achieve a "walking-type" effect also called marquee-effect using individually wired LEDs, so that it seems the lights are moving from one end to the other. Here's a video for reference: https://www.youtube.com/watch?v=p4g2NFQps1g It is easy enough if we have repetition every 3 LEDs. But my restriction is that I have repetition every 2 LEDs. The circuit is something like the one in the diagram(pardon my MS Paint skills): Every other RGB LED is connected together.  One simple way to provide the effect is to show color1 in LEDs at odd position and color2 in LEDs at even positions and then switch them. This is different from a similar effect in cheap fairy lights as I can set the color and intensity of the LEDs besides just on/off... Here is a GIF of my attempt of simple color switching with an addressable LED strip for now: In this, I cannot set any direction of travel and the effect depends on using a bit of imagination... Although it might seem difficult to provide a good effect with just 2 color channels, I want an opinion if it is possible or not?

Hall effect sensor to trigger relay

Hi! I have a project that needs to sense whether water is flowing through a pipe. I bought a water flow sensor on Amazon (https://www.amazon.com/gp/product/B01LVWHJP0/) thinking I could use it as a basic switch, however, it's got a hall effect sensor and I don't understand how to deal with the voltage output. Measuring from the pulse signal to ground, the sensor swaps the polarity each time it's triggered: With water running, I see a positive voltage. Turn the water off and back on, voltage goes negative. My control system can't deal with this. What I need is a simple circuit to turn the sensor's pulse output into a contact closure. Can anyone help? Thank you!

Flickering LED's like a firefly effect?

I got this message over an e-mail, I cant help the guy and hope that yall can help him for me: "Hey guys, wondering if I could get your help with a project for my daughters school play. The effect I want to do is a led sort of fire fly or even a flicker candle effect with about 100 led's. I would like to possibly have control over the amount of time they are off or at times just keep it on steady as a regular flicker effect. The led's would all hang individually above the set, so any resistors would be at the top where you do not see them. I would like this to be powered by a transformer, not battery and plug it in the wall. So to have about a 100 or more random flickering little led's is the goal and executed in the most logical (and clean) way. I have seen long lengths of copper tape and then solder to that or whatever you think. I know this is just a play, but woud mean a lot to my daughter. I can put it all together with a plan and a good source to get the various elements. soooo the idea is have the led's suspended by the cable hanging down maybe 6' from above where I would have a 1 x 4 grid to hang everything from. The led's would either have random flickers on a slow (hopefully) adjustable sequence. Out of 100 led's you would only want maybe 3, 4, 5 (who knows how many yet) on at one time. So just quick little flashes of pulsed light like the flicker candles do. So you would have little clusters of 2 or 3 leds hanging down and I would use black heat shrink to bind it up and the cable (22 guage?) would be black as well. The other idea may be to just have a constant candle flicker effect to each "drop" and leave it at that. Would be great to know how to do both. any sugestions?

Converting to/from line level signal for guitar effects? Answered

So I've got some effects pedals that don't get along with my Egnater Tweaker's effects loop, namely the HBE Frost Bite Flanger, but my Carbon Copy doesn't do too well either.  I've determined the problem to be the effects loop (which is at line level), and the previously mentioned pedals won't accept line level signals without a significant volume drop and high-end attenuation. So my idea is to convert the line level signal being sent from the effects loop to instrument level, run it though my pedals, and then back up to line level and to the loop's return.  This would do the trick to get it down to the right level, but how do I get it back up to line level?  It's passive so I wouldn't think you could go from -10db to +4db, right? I'm also concerned about introducing noise and tone sucking.  Additionally, the send and return both have a different impedance, would I need to compensate for that? Any ideas on a way to achieve this, or a better method that hasn't occurred to me?  Any help is appreciated.
