🔥I've made yet another ESC based on Arduino. Works the same but is a lot smaller having a basic circuit. Is just a prototype so I can't promise nothing more...

Thank you for also showing the failures. This shows how complex it can be to develop a proper layout.

@motherjoon Місяць тому

A few tips, you can always solder one side using a mini hot plate and do the other side with hot air. Makes it alot easier.

@dekipet Місяць тому

Hot air + small component = component lost somewhere in the room Unfortunately, only soldering iron for the opposite side.

@KidCe. Місяць тому

@@dekipetnaah, you just need slow air, soo minimum air speed and big nozzle. i regularly solder 0402 and 0201 with hotair

@rallyfeind Місяць тому

@@dekipetLearn what flow controls do or stop using blow dryers and heat guns. I haven't bought one from Temu to say All but even the old Weller knock offs have a leak valve on the air nozzle end. If you can do component soldering but can't make your station mind you then it is kinda a you problem really. Not trying to be negative but assure you the solution is within yourself and looking at your tools for blame is a cliche.

@rallyfeind Місяць тому

@@dekipet Unless you being snippy with me is fixing your airflow issues then you need to focus on that. I can talk differently but I doubt my eloquence alone will magically make you better at soldering or change the setting on your station for you. Hope that was both polite and informative enough that you actually do gain the reliable skill and can benefit. Now handle the problem instead of trying to be cute please.

8:12 The Atmega328P is NOT particularly sensitive to voltage fluctuations - it officially works down to 4.5V up to 20MHz, down to 2.7V at up to 10MHz, and down to 1.8V at up to 4MHz. But that’s just what is guaranteed. In practice, most of them will happily work at 16MHz on just 2.7V. (On Arduino, the bootloader is programmed to enable the brownout reset at 2.7V.) But what about the rest of your circuit? Does it malfunction below a certain voltage? You probably just need a) more local smoothing capacitance, both bulk electrolytic as well as ceramic for high frequency, but also thicker supply wires to enable the caps to charge quickly enough.

@panklovatina3329 Місяць тому

You can try putting a diode between VCC and (atmega + capacitor). That way, high motor current spikes won't discharge the capacitor and the atmega will have power so it won't reset.

@rahulkushwaha9500 Місяць тому

i have used SIA519EDJ-T1-GE3 this mosfet pair in single package for a similar project. I have rechecked some basic parameters and this will be more than enough for your requirement. gate charge and capacitance is low enough that a MCU will be able to drive it without any problems. although i used gate drivers. package is little bit tricky to solder, but with a hot air and good fixture for pcb, it will be just a walk in the park. This will greatly reduce the space requirements. Also put couple of 10uf/16v caramic caps near the mosfet power rails and atleast one elec cap on the main power pads with short leads. looking forward to your final project. keep us updated.

@tamask001 Місяць тому

It's an interesting project to have a minimalistic ESC, but it would be educational to compare it to a similarly sized commercial offerings, like the HAKRC 35A. I would be curious to learn how the commercial ESC achieves much higher currents, and how the much more complex 32 bit control algorithm behaves under changing load compared to your straightforward loop.

@daijoubu4529 Місяць тому

They have a dedicated driver IC, you can look at the AM32 source code to give you an idea as BLHeli_32 is closed source

@itzblast7512 Місяць тому

@analoghardwaretops3976 Місяць тому

Over current causing repeated resetting of uC was a common hinderance...because this is a random/anytime event...so we got around it with a little additional hardware,so the uC is no longer interrupted randomly..... The over current comparator output was fed to the D i/p of a D ff and clocked on the FALLING edge of the pwm pulse..... The "Q" output of D ff now interrupted the uC. during faults.....Worked like a charm..😅😂

Looking good. I know there are some components out in the wild that can make an even smaller brushless ESC without sacrificing power. I have 3 such components and the only missing item is the MCU which I thought I had found a solid company, but all they did was waste my time. Edit: Sent you an email with photos of 2 of the items.

@Johnny-es9xg Місяць тому

I have fixed interference with brushed motors with a 100nf cap on the input of the motor. You could solder them between ground and the coil outputs. Solder a 10uf cap directly to the VCC and GND pins of the ATMEGA 328p.

@nicolaschampagne8988 Місяць тому

to solder a resistor or a cap this small i usually use solder on one side, i apply flux and solder one side of the resistor to the newly applied solder. Apply flux again and solder the second side free handed now. i hope it helps

You know what I miss in the RC hobby? A GPS with 20x20mm mounting holes. They never come in a easy to mount form factor. I can't really think of a GPS for the hobby that has any mounting holes. A RP2040 microcontroller with the same dimensions would also be nice.

@bynaris3345 Місяць тому

Great video! If you want to further improve your ESC and perhaps make a version 4, you should take a look at the ATTiny861A microcontroller. It is specially designed for this kind of application. A single 64MHz timer (with the internal 8MHz CPU oscillator) manages 3 PWM signals with complementary output, with deadtime management. It's almost perfect for an ESC!

@tariqsingh3747 Місяць тому

Great work, very well made and explained. Have you considered dual-mosfet packages? E.g. PMCPB5530X - 2x2mm, 4A continuous, typical RDS 26mOhm. A smaller microcontroller will be the easiest way to save space though. ATtiny806 has a comparator and is just 3x3mm.

@dennisfahey2379 23 дні тому

Wow that is tiny. You probably want to do something to isolate the FET power from the microcontroller rail. That inductive load is probably creating a back EMF that is coupling right into the chip.

@thirtythreeeyes8624 Місяць тому

The smallest esc is the uESC it's 6x10mm and with flex pcb it weighs about 0.1 grams. I like indoor rc planes and it's about the best and open source. There is a smaller one from microflierradio that is 7x4mm and 0.08grams but, they're only 1 amp and 50 bucks, that's more than the entire cost of most my planes and I don't build small enough for hundredths of a gram to matter anyway. Also the uESC is only two layer.

@JaimeSequeira-zr1rq Місяць тому

Had a quick view of the schematic aqnd noticed there are no trimming/tuning caps on the external 16MHz clock line. Is there a reason for this? I am not familiar with the ATMega product line. Some MCUs have built-in trimming caps. This would explain why the board works but resets after a while (stray capacitance on the crystal line from the PCB is just enough but not immune to noise in environment??)

Is not a Cristal, is a resonator so it already has the capacitors inside...
