In this episode of DIY or Buy we will have a closer look at the VESC which is probably the best open source ESC. Along the way we will have a look at its amazing features and try to build our own in order to find out whether DIYing the circuit is cheaper.

Next time soldering components with many pins, use some flux and less solder. It will work like a charm !

I do PCB design and bringup. You’ll have a much easier time with a microscope, quality tweezers, smaller solder, a flux pen and a quality iron with a micro tip. Everything on this board can be done without reflow. You really have to take your time under a microscope and make everything perfect for this to be worth it. Also that 3 hour time estimate is mighty conservative!

I don't think this is a fair comparison, as, sorry to say, you suck at SMD soldering. (For future adventures, may I suggest you use a LOT less solderpaste, you have about 10 times more than needed.) However, with a price difference of only $2, the winner IS, of course "BUY". Even for a SMD expert, it takes time for ordering parts, sort, mount and solder. The REAL benefit of DIY comes when you modify the scematics and layout to suit your needs, enclosure or whatever.

If you want to go at this lvl of electronics you should order soldering stencils. Apply solderpaste to the entire board and reflow cook it in your oven. You can beef up the Mosfets soldering later on if you need to.

A simple tip before first powering up any new circuit, first measure resistance between ground and Vcc! If you have lets say 2 Ohm you know it will release the magic smoke if you power it up without current limitation.

About soldering... I see you have ersa i- con soldering handle. This is good soldering station only you must increase temperature. For that pcb with lot of copper and two side layer pcb, at least 350°C to set. I have the i-con pico (80W) and much better results when soldering smd components even with classic thin wire without extra flux. I use stannol thin 0.7mm thick. Sorry for bad english...

I have designed a much cheaper proof-of concept ESC, based on old ESC32 code and the "Bluepill" which has pre-soldered MCU. It lacks FOC though. VESC is more ambitious so it uses more external ICS like ADCs and a higher-end ARM CPU. My ESC32 clone uses only the built-in ADC channels of the MCU and one of the versions even skips the current control circuit. The BOM is under 8 EUR if you buy the components from China.

Hey Sccott, you should have asked for stencil along with PCBs. It would have been easier to apply the right amount of solder when using heat gun.

Get yourself a Controleo and combine it with a Pizza oven, add some insulation, maybe a nitrogen injection and you have a really nice reflow-oven. I added some IR heating elements to mine , to get a total power of 1600W. If you use black PCBs it works even better ;-)

You need to update your soldering methods and techniques. Experiment with different types and amounts of soldering flux. The low viscosity (thin flowing) type is preferred. It has surprisingly huge effects on your soldering work. In the case of soldering the IC's first try lightly tin the pcb IC pads. Then clean as usual and flood the IC pads with flux such that the IC pad area literally is a pond (lake) of flux. Now do the actual soldering in the wet flux. You will see that the solder tends to automatically flow to where it should be. You can still use solder paste, but you must control the amount very accurately, as any surplus solder has no where else to go, than the nearest solder pad or pin and will collect there.
Keith Summers
Keith Summers Рік тому
Scott -- at this point you should be using a solder paste stencil to apply the paste. ALSO -- your PCB did not have masking between the pins -- that is not an acceptable quality board. Those guys in China will apply solder between the pins if you demand it. It cost them more time and money -- but you have to ask for it otherwise -- they take that value out of the deliverable.

@Bigatchu I know that L.D is dangerous. But the lasers are used too for soldering.
Bigatchu 2 роки тому
This is actually really hard, because of the shiny surface that reflects the light instead of letting the light heat up the material. Additionally, lasers are very dangerous and you'd have to do everything with special goggles or a soldering microscope.
jonshouse1 2 роки тому
I suggest you buy some liquid flux. When you bridge pins on surface mount IC add flux, then place the solder braid over the flux, then heat with the iron, works well for me.

Hey Scott, I got a question regarding brushless motors: I know that the KV velocity constant is retrieved by measuring the back EMF at a given RPM. My question: is it possible to run a motor at a given voltage with more RPM than voltage multiplied by KV?

Hi, I'm currently busy with a project that uses a VESC - I'm not well clued up with the components used in a VESC, but I was told there are power resistors used to dissipate some regen power to help with braking (ESK8). Would it be possible to swop those resistors out for lets say 500W resistors (with the same resistance) to dissipate more power without recharging the battery used to power the VESC? Any firmware tweaks needed to allow more internal power dissipation? Any help from the comments would be appreciated. I have been to the ESK8 forum, but I cannot post a question and have searched for this topic.

I have a 12v 0.18a 3wire blower dc blower fan, I want to slow the speed down for long periods but need the full speed for initial start up for a couple of minutes. Can you advise me on which type of small speed controller I should buy for the well being of my blower. Have seen vids on transistor/ potentiometer methods but would rather buy the right tool for the right job so to speak. Thankyou. Great video.

I have since bought 12v dc 0.18a brushless 2 wire fan. I bought a pwm controller to vary the speed but the fan did not even turn with the potentiometer in either position. Struggling to get any info even from suppliers. Can you advise what type of controller I need for this type of fan? Thankyou. Great videos.

Dude. solder stencil. send in your solder pad gerber to then just tape down the stencil, squeegy your solder paste across the stencil. Peal it off, apply your components, then hit it with the heat gun at high heat low flow. It's cheap and WAAAAAAAY easier.
