DIY Digital Tachometer - Arduino|Photointerrupter [Tesla Turbine]

Do you want a simple and cheap solution to measure the rpms on your tesla turbine?
No?
Well, that was a little bit specific but if you like DIY projects, 3d printing, science and a smidge of engineering, stick around.
This video is a follow up to my last video on how to 3d print a simple design for a Tesla turbine. This video is also the second of a 5 videos series I’m working on.
The next one will be about the boundary layer effect.

[@tristunalekzander5608]

Many people don't know this, get a new soldering iron and before ever using it, look up how to "tin" the tip. Also, get a thing of flux and put it on everything, including your soldering iron, before applying solder. Your soldering iron tip should be shiny with a layer of solder covering it always. Solder should stick to the tip very easily. I struggled with soldering like you too before taking these very simple steps, now I am the solder king.

[@goldenpiston8449]

hey, just some tips for soldering: you did great but use more flux, if you have flux core solder, don't directly put it on the iron, put the iron on the part you're trying to solder, then add the solder. if it's solder without a flux core, put some solder on the iron as you did, and put some flux on the part and then touch the two. will work great.

[@user-be4yc2vr5c]

Teslas stuff is so cool. I just thought of comboing this with compressing refrigerant gas which is being heated by panels soaking up the enviromental temps which most all are above its boiling point. To hyper condense and pressurize the gas using the special effect the turbine operates on.

[@prressurr]

I believe you switched open and closed around. Open is 0, closed is 1. An open switch is when there's no contact between the 2 poles, a closed switch is when there is. For optical switches this becomes open = obstructed, closed = unobstructed. Good vid tho, quite entertaining.

[@integza]

I'm aware that 0 means open loop and 1 is a closed loop. I just reversed the names because I thought it would be more intuitive for the viewer. The code is alright though. Even if I switched the signals it would be alright because there's an equal amount of "closed" and "opened" per cycle. Thank you so much for the compliment :D

[@anapananapa]

It looked like you had a dual filament extruder, you could get some water soluble filament and use it for support structures or space filling. It might be an option for making the discs.

[@integza]

That's a great idea! The thing is, this printer is recent and I'm getting used to it, also, I never printed with 2 extruders. Thanks for the comment :D

[@coffeecuppepsi]

Kudos for thunderfoot video!!

[@llth_devices]

You might've been able to use the audio method if you did a recording while holding the shaft still, and a recording with the tape hitting your finger. Then in audacity you could have used the "Noise Removal" effect. Use the recording with the shaft being held still as the "Noise Profile" and then use that profile to remove the white-ish noise from the recording with the tape hitting your finger.

[@integza]

I did use my finger and I used the noise removal effect but the air and the turbine do a noise with a big amplitude. But I need to try that again.

[@deeeeeds]

I'd be really interested in seeing if flywheel weight has any bearing on the performance of the turbine. If you do, make sure you modify the code to store previous results along with a time stamp with which you could calculate the acceleration of the flywheel!

[@integza]

Nice idea! I like it!

[@iEnergySupply]

For the best advice on building one of these, take the advise from the inventor, he goes into great detail on how it works and how to make it efficient. TESLA PATENT 1,061,206 TURBINE

[@integza]

Great advice! Just downloaded the patent.

[@TheAltair033]

I know this video is quite old by now, but here are some thoughts regarding the acoustic rpm measurements: there is a free android app, spectroid, that's pretty good for frequency analysis + it might help to attach the microphone directly to the turbine casing, so it picks up the vibrations (so if you're using a phone, just tape the headset mic to it)

[@endurofurry]

Schools should use these videos to teach physics or examples of types!

[@integza]

Thanks, man! I hope they do :D

[@shoofle]

I wonder if you could print spacers to set the spacing between the plates. I wonder how hard it would be to cut the turbine plates out of metal... they're far from complicated! Oh, and I wouldn't write off the frequency-amplitude plot in audacity too quickly - remember that the amplitude is displayed logarithmically, so a small difference in the height of the peaks is actually a large difference in absolute amplitude! You should check to see whether it actually matches up, now that you have your arduino tachometer :)

[@integza]

Hi shoofle ! Thank you for the help :D I like the spacers idea but I'm trying to stay away from metal discs, they're quite heavy to be pushed by air. I was thinking about trying with carbon fiber or polycarbonate. You're right about the audio method, I should've done more research.

[@harelbenyosef8743]

The smaller and lighter the propeller, the faster it will rotate. You will need to invest less energy to rotate it and it will also have less friction with the air. In addition you will try to create a new model with an exit only on one side because there is still an air pocket that lowers the maximum speed. It would be nice to see if the shape of the compressor nozzle also affects the speed, like its thickness or the air pressure it puts out

[@sainathreddy900]

you can measure the mass flow of air by using a simple U tube manometer by using water. And make a few thermodynamic calculations to find who much amount of Max energy can be used.

[@harsharanrahkra9410]

Great videos especially since I am such a big fan of Nikola Tesla.

[@velwheel3135]

The speed of the wheel (rpm) is not an indication of the power that this turbine can deliver. Also, bearings are a weakness for high RPM. Try connecting the turbine to a motor which can be used as a generator, then the useful work the turbine produces can be measured. Good project.

[@karimjerbi7084]

The photo interrupter can be salvaged from old printers saving you $3!

[@integza]

I like the way you think

[@nrdesign1991]

I just tried it myself. Red PLA is indeed transparent to IR, while white PLA isn't. Neither seems black PLA. Also might depend on your print thickness and infill

[@whiphore]

I’d love to see you split your air line and put it through both inputs

[@gmln3593]

Try removing the grease from the bearings with some sort of solvent, you'll have less friction and it should help you in your quest of higher rpm

[@harelbenyosef8743]

Video idea: Wave power(I mean sea wave) Think about a way to gather electricity from the power of the waves. This is kinda new technology so there is a lot of new methods that waiting to be found, or you can use existing method and test is in a aquarium or a little pool

[@gabriele7361]

I think that you should be doing something for your soldering skills. You can try using soldering paste or adjusting the temperature of the iron, even its tip or the solder itself can be the problem... I am not an expert, but try it you will apriciate a well done solder joint.

[@RaivoltG]

Damn I'm glad I found your channel, you're funny as hell! You also do some pretty cool stuff too!

[@spacepirateivynova]

Get some rubyfluid. Put some on the metal you intend to solder. Bang, you can solder a lot better all the sudden! The flux in "flux core solder" really isn't enough to do most soldering jobs well.

[@humbertokokoa11]

You should prove the turbine with some generator to see how much energy can produce with that RPM. I've been seeing some videos on yotube and this it'll be one of all that true call my attention. I'll waiting fot the video.

[@integza]

I'll do that on the next build! I want to test speed but also power and efficiency. In the last video of this series, I will try to really get something that lives up to Tesla's expectations. Thank you for the comment and advice. I hope you stick around :D

[@nemoaluminum]

You are great. Is more easy use the stroboscope efect

[@integza]

Thank you for the advice Breno ;)

[@ronalds5902]

love your content please make more videos! Take Care

[@MrRyanroberson1]

You need to work out "poor person tactics", as I call it. Having two flywheels with equal masses of about maybe 1hg the motor should only need to sorry about absolute elevation of the "kinetic bank", and the total angular inertia should be some inertia h, and with more kinetic energy per velocity means the total power transmission (from air to rotation) should continue smoothly for longer before the velocity jamming comes into effect. The trade-off is then the increased friction on the bottom part of the axis's primary support points, hence the hectogram, but maybe kg could do if it's strong enough

[@A-tech]

it would be interesting to see the rpm just putting the airline on the bit thats getting measured

[@patriciabrighton335]

Try to build egg shaped (Viktor Shauberger inspired) tesla turbine. I think it is would improve efficiency because there would be no 90 degree corners for turbulent flow to slow down.

[@martinkardos3279]

I had a bad day, but you made me laugh

[@SidneyCritic]

That solder wire looks like high tin, which is hard to solder and leaves a bad finish. You need leaded solder, ie 60/40-ish, with flux core. Plus a tub of good quality flux.

[@justaguy6100]

Zo, on the turbine and your need for speed. It would seem that the torque is woefully inadequate for just about anything really. Do you hope to get enough speed to gear it down to where you can actually find an application beyond justifying ultimately (because you know you will) getting a fancy digital photo tachometer? Not that that's NOT a worthwhile goal as well ;-) Color me envious, so green would be appropriate then.

[@CUBETechie]

I don't know too much about compressors but could you start a test with different types of pressure: from 0,2 bar to about 8bar? I don't know what is your max. Pressure. Run the turbine from 0,2-8bar in 0,1bar stepps and measure the speed for about 2-5 minutes.

[@integza]

For that I will need other compressor. This one has a maximum of 9 bars but that's it ... it cant step the pressure.

you're soldering wrong! you don't put the solder on the iron first. well, you put a runny amount so it transfers heat, but you use the iron to heat up the joint and then you apply the solder to the joint so it melts in place. remove the solder and then the iron.
