Yes, we designed a board with 100 microphones every 7.5 inches.Note by way of comparison the machine we put together for this Instructable has a resolution of about 10,000 pixels across by 8,000 pixels high, i.e. much better.So in order to study scientific phenomena, I prefer to SWIM out a 2D space rather than the linear array SWIM, even though the original SWIM that I made in my childhood 43 years ago used a linear array (of only 35 elements = super low resolution): http://wearcam.org/swim/

Tell me more about the wave machine used in your HS physical science class. Was this a PAR (Princeton Applied Research) wave machine?

The exposure time depends on the speed of movement of the robotic mechanism, itself limited by the integration time of the lock in amplifier, and by the requirement for safety and longevity of the robotic mechanism. It is realtime, but just on whatever scale is set by the system design requirements (higher frequencies can update faster, for example). When done in VR, it updates around 60 frames per second, although the original scan still requires whatever the exposure time is set by other constraints. You might find some of my research papers useful in this context.

Thanks for the kind words, Scott!Perhaps you can vote for me.Looking forward to keeping in touch!

Do you need honey and molasses?I've seen some whole wheat breads that have exactly 0 grams of sugar. I'd like to try making some healthy bread that has 0 grams of any kind of sugar.

Excellent! Nice to see some traditional Chinese wearable computing. Reminds me of the 300 year old abacus ring from the Qing Dynasty (1644-1911).

Thank you! More updates to come on functionalities too. Also check out https://www.openeyetap.com/ where you can keep track of our updates and share your ideas on what functions may be useful.

Yes, you need another wire connected to the terminal that I labeled "IF". That wire goes through an amplifier to the LM3914 input. The choice of amplifier gain is up to you, depending on how sensitive you want to make it (e.g. how far away you want to pick up objects, etc.).By the way, let me know why the rush, e.g. what is the deadline (usually I do these things just for fun, on my own clock, whenever I feel like it ... to be done).

Yes the waves are very visible by the naked eye. If you wave a SWIM fast enough you can see it very clearly.

Excellent! This looks really great. I also like the way the bright blue light stands out against the dark red background. It also has pretty good range and responsiveness.

You need a S.W.I.M. as per the other Instructable,as well as a rotary motor to spin it, a wheel mechanism and counterweight (or balance it in middle), and a rail to move the assembly back and forth while it spins.

Looks really good!Very nice to see the way it flows....Try this also with the SWIM (Sequential Wave Imprinting Machine) and ultrasound transducers.

Yes, I'm around today (are you in the Toronto area today?) and would be happy to help out, if you want to bring your circuit to our lab and we can take a quick look at where you're at so far.

It looks very nice. Is that a 3phase motor with H bridge from the DC input, or does the motor have brushes?

Looks good.The .gif image doesn't seem to show properly. Perhaps you can post the individual images, e.g. you could put the individual pictures into a reply.

Windshield washer fluid is alcohol.See this article about how to make your own windshield washer fluid:https://www.diynatural.com/homemade-windshield-was..."... 8 oz. isopropyl rubbing alcohol (high proof vodka can be substituted)"(it specifically mentions "vodka").Since windshield washer fluid is alcohol, and has been for many years (it used to be made of methanol which is "wood alcohol", many years ago), it would seem that the materials selected for the design of windshields, and their mounting, would need to be designed to function well in an alcohol infused environment.See also https://chemistry.stackexchange.com/questions/1092...

There's multiple cameras on the EyeTap. The PiCam is there along with some other cameras. The EyeTap is a nice general purpose experimental apparatus with the optical rail along its length, so you can add many other sensors for sound waves, radio waves, thermal, infrared, ultraviolet, etc., sensing.

Looks good.You might want to also try to use a flash light at the beginning of each exposure so that you can see a difference between the head and the tail. There should be a head that's sharp and clear, with a blurry or smeared trail of light tapering back to the tail.Alternatively you could let the head "burn in" more, e.g. let the head sit still for more exposure time, while ending the exposure abruptly for the tail. Right now the head and tail look the same, but if you can make them more distinct from each other, you'll get a better result.

Looks great!It would be nice if there was a way to make the head and tail distinct from each other. One way to do that would be to introduce a flash light at the beginning of each exposure to pick up some ambient details in the scene at one end (but not the other) of the exposure.

This looks great!You might also want to try using a flash at the beginning of each exposure so that there is more distinction between the "head" and the "tail".Another alternative would be to let the head "burn in" more, e.g. let the head sit still for more exposure time, while ending the exposure abruptly for the tail (don't let the light stay still for the tail, e.g. cutoff the exposure at the right time so that the tail's still moving during the exposure).

Yes, this is a very nice looking light source.It is better to move the light rather than the camera because then you can flash the exposure, e.g. have a flash light come on briefly at the beginning of each exposure. This "flash and blur" technique is quite common in photography. See these examples: http://www.perfectlandscape.com/helena_blur.jpghttps://photography.tutsplus.com/tutorials/how-to-...

The light motion looks great!For the star, try also doing the easement trails as well, e.g. since it is essentially cyclic in nature, let it build and trail out, as it goes around the cycle, otherwise it builds up and then decrescendos suddenly.

Looks great. I'd love to see the 8 steps applied to this RGB mouse!

We actually did that.Maybe we should include that in the Instructable....

Looks good. There seems to be a glow at one end; is the sequence backwards maybe? Also what light source is this? Keep up the great work, and maybe you can show your results in tomorrow's class.

I'm just uploading your image here (trying to test to see if I get any different result)...

The current kit only has 3D printed part. We will put together a "ready to be assembled" kit soon on our website with all the parts.

Most of the components are off the shelf, and some are made in house. We are selling them at OpenEyeTap.com. We are still updating the website. Stay tuned!

That's a good idea; I'll try some waxes next time (maybe that will help the tree sap not stick so well.Free alcohol comes from speaking gigs, talks, etc., e.g. even though they pay me to speak, they also often give me a bottle of booze. That seems to happen a lot in the academic professorial world. To get free booze: study at graduate school, finish your PhD and get a faculty position and do some interesting work and it is likely people will invite you to speak and give you free meals. And free booze that you can use to wash your car with....

I'm interested in electric vehicles and experimenting with secondary electrical systems, and we're also looking at possibilities of converting vehicles to electric usage. A secondary electrical system is also useful because we do a lot of research on smart cars and instrumented cars, etc..

As mentioned by bcrocker1, vodka smells pretty much identical to other cleaning fluids like methanol (previously used as windshield washer fluid and antifreeze), propanol (solvent, industrial cleaner), etc..So for the few minutes before the smell dissipates, it will smell a lot like cleaning fluid.Don't drink the fluids. The smell stays for a long time on people who drink alcohol, http://alcoholrehab.com/alcoholism/smell-of-alcohol-breath-pores/

And it is often cheaper than IPA (IsoPropyl Alcohol). That's why we use vodka to clean the soldering flux off circuit boards (we used to use propanol for that, but found that vodka is cheaper and does the job just as well).

Yes, I took a look at the Rain-X video on YouTube and it looks great. I'll try some next time I do the windshield....

Move to California, where the safe operation of a motor vehicle is made easy by way of readily available dish soap, Windex, vodka, and Rain-X.

I'll try some vinegar and see if that works well (e.g. if it evaporates quickly and leaves a nice shine, etc.). One reason I used vodka is because I already had lots of vodka sitting around here that would otherwise go to waste taking up space in the kitchen cabinet.

Yes, vodka is available in every grocery store I've ever been to in California, and it is really cheap, and it is usually right by the checkout so I always see it and remember to get some while checking out. At Trader Joe's it costs $5.99 for a nice big bottle (a metric "fifth") and $9.99 for the extra large size (1.75 litres which is more than two fifths). Burnett's comes in cases of 12... $71.88 well-spent! The larger size (Vodka of the Gods) works out to about $21.61 per gallon. Cheaper than many cleaning fluids, works great, dries up quickly, and leaves a nice shine.

Sensors like these transmit infrared energy.More generally, some sensors transit energy whereas others don't transit so it is harder to pick up the signal.There is a lot of literature about bug sweepers in general, and detecting cameras in particular.My contribution is less about new detection methods and more about how to present the data once detected, i.e. concept of phenomenological augmented reality ("Real Reality"), http://wearcam.org/par/--Steve, http://Mannlab.com

Excellent!I look forward to seeing some more pictures, especially if you're able to get something where we can see a nice "veillance flux" pattern. Take a look at http://wearcam.org/abaq/for some inspiration and ideas, etc..Keep up the great work, and I look forward to seeing where you take this!Steve

Excellent work. Looks great!Yes it is a cosine or sine function of space, depending on the phase....See http://wearcam.org/kineveillance.pdffor a nice detailed mathematical development.

First see if the individual components work separately.For example, see if you can get any of the lights to sequence irrespective of the phenomenamplifier. If you get that much working, move to the next step.Also see if you can first get the phenomenamplifier working with just one LED, and then add the trick of more LEDs once you have it working with one LED.The idea is that if it works with one LED, you can sequence it (i.e. have them come in sequentially), as in http://wearcam.org/surveillancestudy-36exposures/

Yes, and I think it should also be in many fitness centers as well.

Very nice.I wonder if this would be as easy to make in Fusion360 (e.g. cloud-based for realtime collaboration).

There's a lot of controversy with many people believing there's no such thing as "persistence of vision", disproved in 1912 by Wertheimer[2] https://en.wikipedia.org/wiki/Persistence_of_visionSince there's no such thing as persistence of vision, let me instead claim that there's at least a concept of persistence of exposure.PoE (Persistence of Exposure) when combined with perfect alignment, as a form of real augmented reality, gives us the ability to see otherwise invisible real world phenomena, as well as complex-valued signals from the physical world around us.See Figure 7 in http://wearcam.org/kineveillance.pdfIf you can think of a better title, please let me know.

Yes, it was wonderful to get to know you and so many other great people at Pier 9. Those are memories that will last a lifetime!It would be great to learn how your analemma chandelier is doing and if you've got it installed and running yet.I'm glad you enjoyed the picture; perhaps you've got that up somewhere too.

Thanks for the kind words!I really liked your Flat Pack Solar Oven (my grandfather used to make lots of solar powered things when I was growing up, and we made parabolic solar oven reflectors, etc).

Very nicely written Instructable!One thing I notice is that when the checkbox of a parent directory is deselected it deselects all its children, but a child directory can be reselected without having the parent directory selected. Thus there are two possible states that appear to represent the same selection.

Looks great. This is kind of like the axis labeling function we had on some of the S.W.I.M.s where the tick-marks are included on the across axis (with also bars across the up-down axes). I'm at Instructables P9; are you ever in the city; if so it would be fun to meet and collaborate on this if you happen to visit the city in the next couple of months or so....

Excellent!Do you need to gradually adjust as the Sharpie wears out a bit?I imagine on larger jobs it might wear a little, and need to be lowered a little more toward the end of the job.

Also since this is really 2-dimensional in all regards, could it be done from a 2-D program like Inkscape directly, or perhaps from C-code directly, e.g. write a C program to define a mathematical function and plot it directly in realtime without having to use any software in between.Need to figure out the communication protocol of the Shopbot....

Yes, as long as you back in (back wheel in first), all the bikes, the handlebars are not a problem because there's enough space at the front. The "pie-shaped" spaces work well for the overall shape of a typical bike (wider at the front due to handlebars, and narrower at the back).Let us know if you end up making a version of this for scooters.

Why "mixed reality"?Mixed reality only gives you the virtuality axis, but you might also want the mediality axis.Compare figures 1 and 2 in https://en.wikipedia.org/wiki/Reality%E2%80%93virtuality_continuumand see also https://en.wikipedia.org/wiki/Computer-mediated_reality
