Very cool! I was planning on trying something very similar I just wasn't sure how to go about it. I bought a few cc1101 boards to try this out in the supported ranges. I'm using an esp32-s3-wroom-1 on a very similar expansion board. I'm even using a speedy bee stack on mark 4 7in clone. I'm working on a mic array for detection too. Kinda just sticking stuff together and seeing what works. I'll get better hardware as I learn more. Good to see someone else on the same ideas!
cc1101 would be for detecting the RC control right? Anyways, good luck on the project!
Yeah and a few other things. I got them for $1.50. Figured I could learn something RF related. Eyeballing a rf one clone (15$). Memory marinating until I can eventually detect drones and fpv. Just ordered parts for an OpenIPC system. Good luck on your project as well. Subbed with notifications. Really interesting stuff!
There's more than 46 channels on a lot of 5.8ghz vtx, AKK even has them with 96 channels and tramp protocol allows inputting any arbitrary frequency.
@@thirtythreeeyes8624 the hardware I’m using can be tuned to any frequency (similar to how Tramp uses SPI to set freq) I’m just using a “standard frequency table” to make the search faster. But I can write a separate mode to sweep the entire frequency range from 5.0-6.0 GHz
Put this on a loitering drone to boost the signal through jamming equipment. Brilliant stuff JB.
@@BirdRunHD the plan is actually more like Drone - AWACS or EWR
@@Jdogdrums7 Those are nice too but the real hot topic now days is how to get a drone to burn through jamming and you have a part of the solution with off the shelf parts that corps can buy some day.
@@BirdRunHD Personally I think this would be more usable as a “Home on Jam” device rather than something to steer an airborne transmitter. A better solution thats already solvable is to point an airborne directional antenna via compass bearing via ELRS telemetry data (out of the rear of the drone - so “rear bearing”). That would eliminate the sweeping which would breakup video quality.
This is cool
for monitoring the air or also jamming?
@@JonnyWaldes This is monitoring only
For jamming, you could hook up a transmitter and write the frequency over SPI to “ReJam” the locked frequency once found
@@Jdogdrums7 It wouldn't work very well unless you have heaps more power than the drone or get the jammer up high enough for LOS to the receiver and then they could be using the opposite polarization antenna lol
@@thirtythreeeyes8624 yea you would need a network of jammers which would get very involved very fast. This is mainly for detection and direction finding
Interesting stuff. Thanks, and subscribed
@@alexanderg-p3z will post another update this weekend. Hopefully will make a much better video demonstrating the performance and possibilities with networking and remote access features that I just tested.
Very neat! What if you translated 0 degrees to be 12 o’clock, and the rest between 9 o’clock and 3 o’clock for faster orientation as the user.
@@De1taX That’s doable for sure. Basically you would just convert degrees to “clock” direction using a map() function or something. The reason for degrees is to eventually map the frame azimuth into the code, so that the output is actually a magnetic compass bearing.
@ That’s awesome! I’ve been messing around with a Raspberry Pi Moisture sensor watering system, almost done with it and is working well so far. Next project I want to get into is something similar to this but with 3D Lidar Mapping.
@ nice! Lidar sounds like a really fun sensor to use and experiment with.
it's beautiful
could you link to your project's writeup? I am not sure what this is for
The other videos explain it better. This is a direction finder for Analog FPV video commonly used on drones.
Really impressive work!
Cool Stuff!

Thanks, i was able to locate my lost cat using this technique.
Cool project looking forward to the final result
Nice!

Hi Jordan Brock, my name is Alex, and I’m writing to you from Ukraine. As you might know, our country is currently at war due to Russian aggression. In these challenging times, detecting and countering UAVs is critically important for ensuring safety and defense. I came across your UA-cam channel and was very impressed by your open-source project "Signal Detector." It seems like it could be highly useful in addressing the challenges we are facing here. Could you please share more information about the project? I’m particularly interested in understanding how it works and whether there are opportunities to collaborate or contribute to its development. Thank you for your work! I look forward to hearing from you.
@@mrstarklabs I am currently in development and will try to post updates as the project comes along. In the meantime, another Open source project “rx5808 pro” is based on Arduino and a common FPV module “Rx5808” found cheap online. This module is also what my project is based off of. If you acquire the 2 pieces of hardware and get it working (Arduino / Rx5808), then in the future, my system can easily be adapted and firmware uploaded to Arduino with addition of a directional antenna
you could literally just ask chat gpt to make this for you lol
@@Jdogdrums7was going to ask who's app that was. I take it, it's your own?. Backing a few projects at the moment to get an open source signal anayser that's works with rtl and hack rf modules.
@@TheWebstaff this is actually just the old Arduino IDE before it got updated. I did write a plotter script in Python for the new hardware, but it’s still in testing. I posted a video of the newer hardware and basic functions.
@@pickeljuice9325 I’m better than chat gpt muahaha
I didn't know what this is but keep it it, just don't ask aliens for money!
LOL
or us. got no idea wtf this is or why youtube recommended it.
Great demonstration. Based on the Servo motor im guessing this will be used as an automatic directional antenna pointer for your drones so you don't have to manually point at the drone all the time?
@@DPIAPU More than that, I’m testing direction finding capabilities. This vid is a few months old, and I have a working prototype now.
@@Jdogdrums7 What does your prototype do differently than the current tech out there?
@mejcaprod1413 well I would have to compare specifically with an example…but my goal is: Cheaper, Open-Source, COTS parts, and Modular with other common hardware/software
I remember building one of these years back. There are a lot of projects like this. In my experience documentation quality will be the make or break for adoption.
@@AlexanderGee The ultimate end goal is integration with an SDR suite. The current hardware is paired with a cheap Hardware 5.8GHz demodulator for picking up FPV for now.
Context?

HELL YEAH BROTHER
Pls say sir this project big drone motor
Why not use the moving air for cooling during flight? When the UAV is at flight, have an opening for air to come through. Wouldn't that work?
Can you plz do an instructional video on how to build/assemble it? Thx
when you start really testing things out, you come across a strange, but logical, effect. its called "jacobs law". as a generator, it is nothing more than the demonstration of a magnet down a pipe. it takes effort, work, to move that magnet against the induced eddy currents and their opposing fields. we cut a slot in the pipe and there is no eddy current, no opposing field. no work done. we bridge the slot with a resistance. we measure a voltage drop across that resistance, and calculate a current through the resistance. we say we have so many watts flowing through the resistance. we forget that the GENERATOR ITSELF is a resistance. and as a current flows through it, it must also dissipate so many watts. and then if the load and the generator are EQUAL in resistance? we get half the power dissipating in the generator, half in the "load". the engine DRIVING the generator sees TWICE the power that one reads across the "load resistance". we increase the load resistance and reduce the current flowing, the same current through the generator. we now have far more work performed or "lost" in the resistance, versus wasted in the generator. overall though, less work is done in the circuit, as current is limited by the load resistance... easy to verify, just an IR2 equation... the generator always consumes a proportion of the work supplied by the engine, and only really is "efficient" when barely loaded, when the load consumes a far larger proportion of what little power can flow. the generator _could_ deliver far more power into a lower resistance, but in doing so consumes more power in its OWN resistance. when completely shorted , ALL the power is dissipated in the generator itself, the current will be at a maximum, and the voltage will be the potential developed by the current flowing through the resistance of the shorted generator. the "lenz reaction", the magnet in a pipe... at 100% efficiency, you can only get 50% of the engines power out as electricity, volts x amps. and it will ALWAYS be LESS than 50% as there are losses. thats the biggest joke about "efficiency"... you get HALF at 100%. not ALL of it, not "100%"... you get HALF! seems everyones forgotten about that basic aspect of physics... PE=2gh, and KE = 1/2Mv^2. jacobs law is just the electrical equivalent. like "therevins maximum power theorem". its like impedance matching in amplifiers. if the load is a LOWER resistance than the generator, the majority of work is performed in the generator, and the "power" read across the "load resistor" will be proportionately less... the KV rating of the "generator" will determine the RPM it needs for a given voltage on a given resistance until its reached its limit. be it magnetic, RPM, or resistance/insulation, etc. the voltage will be limited by the current it can flow through a load resistance. when the resistance is too low, too much current can flow, the voltage sags, and the generator is overloaded, yet the "output power" appears to reduce, despite the braking power produced by the generator INCREASING. then theres rectifier losses, and all that jazz as youre switching from AC to DC, etc... and finally, batteries arent resistors. below the charge voltage, they consume no current. once they are held at a potential that charge can take place, they draw current. that current is only limited by the batteries internal resistance, and pulls the voltage down. if the generator cant maintain he current at this new voltage, it sags further... either you stall the engine, overload the generator, or the batteries simply dont charge properly. ideally the voltage will only sag to the charge voltage that accepts that current and everythings fine... the problem is as the batteries do charge, the voltage rises... and so does the current delivered... too much current only causes IR2 losses as heat in the battery. it isnt "charging" it.
The main purpose of this setup really has nothing to do with Load / Generator matching, but is to test 3 concepts: 1. Increasing Rectification efficiency, not anything to do with Conversion efficiency (equivalent to the type of Motor Drive commutation) If you look at Motor MTPA (max torque per amp), you find that Field Oriented Control is a more efficient commutation method than BLDC Trapezoidal commutation (Tangential or “Direct” axis current losses compared to the Useful “Quadrature” current) These losses can be observed in Rectifying from a Motor and not just driving it with current. I guess you could call it MAPT or (Maximum Amp per Torque) meaning no Losses suffered from incorrect or “Direct” axis current flow 2. Field Oriented control eliminates the Usual need for very large DC Ripple capacitors like found in most Mechanical Generator setups. This is because the only capacitors required is really for the Transients due to the MOSFET switching and not the “Sinusoid humps” that are usually found with Passive Diode rectifiers. Diodes act like Gates, and instead of letting the Current follow the Quadrature axis completely, they are Passive and uncontrolled, and so they allow Direct axis current flow. They also usually have a larger forward voltage drop and higher Resistance across them than closed MOSFETS do. 3. You now have Way more control over your rectification (diodes are just based on Voltage drop between the motor and the load) and the VESC can limit that, or it can even Drive the motor (useful for starting up the ICE in a neat package, you would need a separate starter in a Diode rectifier setup) You can choose between what your Priority is for your operating conditions: DUTY CYCLE (Varies torque and current for stability) CURRENT CONTROL (useful for meeting specific torque or wattage needs) SPEED CONTROL (if your Setup needs to be regulated based on Physical RPM without much priority on Power regulation) TLDR: This test really isn’t testing ICE generators at all, this is just a Generator setup to test varying Rectification differences and efficiencies. These things could be applied to any Mechanical generator (small DIY Wind Turbines, Low head dam turbines, etc.)
Roughly how many psi is this and if this was put on a vr6 2.8l engine could it make 50 to 60 hp
We don't have actual boost numbers yet, only theoretical numbers based on RPM's that we've achieved compared to Compressor maps. Whatever your current HP on your engine is, multiply it by 1.3 and that is approximately what I've achieved so far. HP gains vary on your engine.
this is cool, i have a similar setup but im using a watercooled nitro engine and a brushed motor to start and stop it.
Ah. Um. Um.
Erm Erm Erm...
Very cool. I've never personally seen a RC aircraft throw a prop but it still bothers me whenever I see someone positioned in line with the propeller disk. Thanks for sharing your work with us. I'm a new subscriber and I look forward to future updates.
It’s a valid concern for sure, but I guess I’ve gotten to a point where I’ve been chopped and hit so many times that I probably take some more risks than I should lol
Очень много говорит!
Hi How model VESC did You use? Thanks Pawel
just a cheap Flipsky 4.20 for this test. There aren't any VESC's much worse than what I used here
So what has brought me here is I scored a couple of 1/8 hp electric motors on some swirl cage fans. I keep thinking to myself of random things I could use them for… lol
I’m not sure 1/8 will do much of anything. This Castle motor I’m using is rated above 10HP.
Very nice and very good work god bless you ❤❤
is that RPM o the motor or the impeller?
final Impeller rpm was around 25k We need a higher voltage battery to get more speed at this point but we knew that at the beginning.
@@Jdogdrums7 Love the work you're doing, awsesome stuff
May I ask one question : When engine Start and running, in this case motor is a generator, there are 3 phase electric forward to esc, why the esc not bunning ? Thanks
The direction of the power does not affect an ESC. This VESC feels the same driving the motor, as it does rectifying current from the motor.
running in free air like this doesn't really show much it needs to be run the pressure the load on the motor is going to be vastly different as well as the turbine its self
We do have a restrictor at the end of the black hose which builds pressure within the housing. However I agree that this does not simulate an engine at all…it’s the best way that we can test the setup without putting it into a car
How much psi did the turbo make and how fast dose it spool and lag time
It was just moving air in this demo. In order to make boost it needs to be able to force in more air than an engine it's connected to consumes naturally. So the amount of boost it can make is not a property of just the turbo, it depends on the combination of turbo and engine. Regarding spool / lag time, I would expect it to be very low, since an electric motor can deliver maximum torque from a standstill, so it should be able to spool up very quickly. Also since it's not relying on the exhaust flow to power it, you can spool it up preemptively, or perhaps in some circumstances even choose to keep it spooled up and use a blowoff valve to control boost pressure.
It is indeed building pressure due to a restrictor plate at the end of the black hose. It’s the only way for us to simulate building pressure without actually putting this on an engine…which is difficult to do because that engine needs to be tuneable and must be strong enough to take the boost without blowing up. We don’t have an engine like that to Test with yet, but we’re working on it
Tesla needs one of those!
to do what? push air through the electric motors? You do realize what you're saying here, right?
@@8Ham_Radios yes
@@8Ham_Radios electric turbos are for electric cars, sounds legit
YEAH UH ROTREX DID THAT YO! NICE TRY 😂
u guys need to understand that ur only going to get at most 1-3X ur input power back. ull need a 50hp electric motor before u start getting appreciable returns
Yeah good argument. At this point you might as well throw 2 electric motors on the rear axles, and spin the tires, instead of a turbine. Nonetheless, interesting video, I want to see some more applications.
Something to consider though, is the cost and effort. If the electric supercharger and its battery adds power for say, $1000 and takes only a few days of constant work to add on, and 2 electric motors and its battery costs $5000, and takes 5-10 days of constant work to add on, then there's a good reason to choose an electric super charger over an electric motor.
Your comment contradicts itself... If you are using a 50HP electric motor (Which has actually been demonstrated to gain 150HP - 200HP to a 6.0 Liter engine), then that is much more beneficial than only adding 50 HP to the drivetrain by adding power to the wheels. The reason for this is that you are actually changing the Volumetric efficiency of the Gasoline engine which is a non-linear relationship between Power required to boost, and power achieved BECAUSE of that boost.
@@drdaedalus880 The main benefit of an Electric supercharger is that you can now Store and Manipulate power at different times compared to a regular Supercharger. With a regular Supercharger, the power in and power out is Simultaneous due to a Mechanical belt-drive. With an electric Supercharger, you can charge power back into batteries over time during Normal Engine use...and then Spend the power Boosting during High Power demands without any power being robbed during that pull.
@Jdogdrums7 Interesting, I didn't know the power gains were that substantial. It goes against intuition to think that a 50hp electric turbo and 50hp of direct drive produce 2 wildly different results. I didnt think of volumetric efficiency.
which vesc are you using?
Just a spare Flipsky I had laying around. I discovered a heat issue with the Flipsky regulators so I’ll probably be getting an OEM soon
@@Jdogdrums7 im having some issues with my throttle on the flipsky controller, they are very sensitive, any idea how to fix that?
@@tomsgokart Are you using Current or Duty cycle control? If you are using Current, then your input sensitivity is determined by your max Motor current. The VESC maps your input range to your Minimum and Maximum Current range (Usually starts at 0 and goes to maximum).
