In this video we will be having a closer look at 4 of the newest ICs out there and their dev boards. ICs are integrated circuits and they can do pretty much anything nowadays. So in this video we will explore some motor controlling, touch sensing, Bluetooth positioning and current measuring ;-) Let's get started!

0:00 Why Dev Boards are AWESOME!
1:13 Intro
1:58 BLDC Motor Controller Board
6:06 Capacitive Touch & Movement Detection Board
8:07 Bluetooth Indoor Positioning System
11:24 Current Measure Sensor
14:00 Verdict - วิทยาศาสตร์และเทคโนโลยี
It's always amusing to me that dev boards are either considerably cheaper than you'd expect or considerably more expensive, there never seems to be anything in between lol
haha exactly, they are either 20-30 euros or 150-200 euros
The manufacturers usually fall into one of two categories:
The ones who understand that they should subsidize the cost of dev boards so their chip gets integrated into more products, massively boosting sales.
The ones who know their customers are usually large companies making unbelievably expensive products, and so they create a barrier to entry that pays nicely.
@@asm_nop nah, its also often so that customers contact the supplying company, often you can get discounts or free after getting advice from the chip suppliers
@@Steyn12 try that with TI, some dev boards cost 4 to 5 digits.
Oh, hello there
For those interested in the u-blox XPLR-AOA-2 Explorer Kit, the kit is based on u-blox's NINA-B411 and NINA-B406 modules, both using the our nRF52833 SoC with its Bluetooth 5.1 Direction Finding capabilities to determine the Angle of Arrival(AoA).
@NordicSemi do you also have some samples for testing for university students ?
@@syousufimam same question. I was interested in using it for my masters thesis but the price of the devkit is a bit overkill. BT AoA/AoD is pretty new stuff, did found some other boards but all of them are either hardly available or expensive. Well teoretically speaking it could be possible with any 5.1 or newer bt device, but you would need an additional antenna array and rf switch for the antennas. and ofc some coding to set it all up.
Silicon Labs also has AoA/AoD kits, which are cheaper (and arguably, better)
@@l_szabi cheaper it could be ... But better ?? Can't comment much , I have used other Nordic products and they were just amazing.
Why would I be using Bluetooth AoA for $1500 when I can be using UWB for $100 ?
That's a very nice little current sensor board! That might actually be a nice alternative to the Zero Flux sensors we use in our superconductivity lab for simpler setups, since these Zero Flux sensors are quite bulky and quite overkill for many small experiments
Great Video! Thanks for sharing (the good and bad)! Going into the details of what it takes to get the boards up and running was super helpful for someone just starting out like myself!
I found a crude but VERY effective way to clear solder points clogged with solder! Touch your iron to the clog long enough to melt the solder, then move the iron and IMMEDIATELY blow air into the point. It does splatter molten solder in the direction you blow the air, but if you use a damp paper towel as a backstop, it's perfectly manageable. Obviously, keep a distance of at least a few inches between the board and backstop.
Awesome video again Great Scott! I love seeing you test new to the market ICs!! Keep it up!
Thanks! Will do!
Thank you, I have been validated! I’ve been using the “heat the pad and smack the board on the bench” desoldering technique for,years!
Lol ! I just wrote the same thing telling some bloke off for not knowing this technique ! you are indeed valid.
I use a metal solder sucker I got in a bundle of crap being thrown out from the IT office at my first ever job (temporary 4 week job right when my final high school exams started)
Those metal solder suckers really are the cleanest way to remove solder. Even more effective than smacking
Great sponsor! Likely the best store ever. I once ordered some items that were only available in the US and I had them like 2 days later. It's not the cheapest stuff you can find, but their service is amazing. No, I'm not being paid by them. They're just great at what they do.
Another BLDC controller option is the B-G431B-ESC from ST. It is a board with a STM32G431CB microcontroller and is designed to be used as an ESC. It is a microcontroller so it does need programmed and is reprogramable but they have some example code and software. The MOSFETs are rated for 60 V and 120 A (although this is cooling dependant, the dev board with a propeller blowing air over it apparently has a max current of 40 A). It supports multiple drive types and hall sensors.
The board is also pretty cheap, better priced than normal drone ESCs.
Just looked these up. Looks pretty cool! Thanks for the suggestion!
Great content, loved seeing these dev boards in use.
Like all of your your videos, another amazing one! I live the way you explain things an show us how they work. Great job!
Thank you very much!
Fascinating boards and ICs indeed! 😃
Thanks, dude!!!
Stay safe there with your family! 🖖😊
Thanks for the feedback :-) You too
Very good Idea about demo PCB from Mouser, very good way to present it by You!
Awesome boards, nicely presented. Especially loved the bluetooth indoor positioning system. Wonder if multiple mmWave Radar sensor antennas could use AoA to sense human presence in multiple axis.
bluetooth prositionning has always been shitty and impractical for actual product, unless the sole product of the startup is a positioning device and the startup wants to spend a whole year on the hardware and product design.
Besides, what they forget to mention is that between this demo baord and an actual functional indoor positionning system there is quite a gap, you will need several base station, positioned strategically inside the building, and the whole setup will have to be very well though and tested before it can even start to work, and this process will have to be repeated or each and every location, which makes it a very unpractical product to sell and deploy at the client site.
You'll also need some kind of processing unit that will gather all datas for the base station and determine the actual absolute position of each beacon.
Needless to say this is no small project, lol. In reality, the only decently working technology for assets tracking is UWB and long range RFID, that is how it is done in the industry for a while, it is now cheap enough, so it doesnt make much sense to bother with bluetooth, which is not a suitable technology for assets tracking in the firsat place; AoA and antenna array kinda make it work, but uwb does a lot better job in the first place due to laws of physics.
Check out the Hi-Link LD2450. It uses FMCW 24 GHz to get the x and y-axis position (side to side and near/far) of moving objects
I just had a PCB manufacturer reach out to me about that exact issue with THT holes being filled!
Long story short I had ordered a pile of PCBs inc component supply and assembly, but did not include THT component assembly due to manual handling costs. Just before shipping it was picked up that the THT holes were filled, and they asked if I was okay with that - which I was for this small batch.
Will definitely use your trick of smacking it onto the table! Usually I just get angry with my solder-sucker trying to clear them hah.
@6:20 You can interface this chip IQS231B from Azoteq with the Microchip PIC microcontrtoller and do lots cool things, adding a proximity and touch sensor to anything you want.
With the IQS cap touch dev board, the proximity sensing is all to do with the sensitivity of the touch sensor. It has 2 touch channels. 1 to detect touch and 1 way more sensitive to detect proximity. That coupled with the electrode design, you can relatively accurately detect proximity on your bench. But in real life, it gets tricky. Make sure your ground plane is always constant.
You have new interesting elements to develop new projects. All the best
You can also use TLE9879 BLDC SHILED where you can stack up to 4 BLDC motors on Uno board and can control 4 motors independently. It also supports sensor less Foc and hall sensor trapezoidal control.
I love Integrated Circuits!
I would like to make a 555 timer from transistors only and a custom PCB.
Would be interesting.
I know it may sound silly but it's something new for me to try out.
Sounds a bit daunting but fun ;-)
There exist kits, but they have a lot of components, so goodluck with making your own pcb
Yeah, thanks!
It's for a future project.
Speaking about today's sponsor, Mouser has a pretty nice kit! It's called "Three five discrete timer"!
But it's good to design it on your own!
Oh yeah! I forgot about that! Thanks for telling me.
ublox RTK GPS modules are amazing, its got centimeter accuracy and have a major application in photogrammetry and surveying. in future some more applications can also be started.
Thank you for sharing this.
You should try and see if the Azoteq sensor is susceptible to being triggered by general RF noise from say a HAM radio :) I have seen that to be an issue which does not make this reliable. However, maybe there are some tricks around it. The whole azoteq lineup could be a nice show idea for your channel :)
Great collection! The BLDC board; did you find out the slowest possible steady speed it could run a motor? I'm looking for a direct (gearless) drive for a telescope mount.
Thanks. My fave channel!
Thanks for sharing! I found the Bluetooth positioning system interesting in particular. Unfortunately, this is too expensive for makers.
I love the technique of heat and slam on the table to clear out the vias
Yep "works like a charm"
4:40 you can buy a soldering iron with electromagnetic pump very cheap nowadays.
It is not as productive as proper desolder, but it would solve problem with closed holes for a few minutes.
Looking at the desoldering troubles it seems you should really consider investing in one of those Hakko desoldering guns. Trust me they are worth it. But the cheaper way to remove solder stuck in the MCU pins is the use a conical tip to heat it from the top and a desoldering pump (a decent one) on the bottom to pull the solder out with the board stuck in a vice. It Always works
Seconding the suggestion of a hakko desoldering gun. I would specific either a proper hakko one or at least a more expensive one. The cheaper ones are not worth it unfortunately, I tried several before biting the bullet on the full blown Hakko.
@@medes5597Not true at all. If you can't make it work with a yihua, then it's you, not the equipment.
@@AtlasReburdened admittedly not used a Yihua but I'd consider that to be decent and well made - at least in comparison to what I meant. I was meaning more the very cheap ones that are littering Ebay, Wish and Alibaba currently.
What trouble ? it took him seconds and its a tried and trusted method developed over years ! You should begin learning this technique straight away .
For clearing holes, I also like to just blow through a plastic straw to shoot the lead out. No rearming the desoldering pump😁
Very cool position sensor. I am very interested to see you evaluate GPS RTK one of these days.
Next time you have filled holes, before smashing the board on the desk, just soak solder braid in flux, put the end on the hole, heat well, then slowly drag the braid off the hole, and all the solder will come out. Easy, clean, and no violence. There is a TH-cam channel called Mr. Solderfix which is run by someone who knows what he's doing. He demonstrates that technique very well.
Thanks for video! VERY interesting!
uBlox for drone signal strength would be so cool. My ground station would always point toward the drone haha
Just last month mouser electronics stopped supporting shipping to Pakistan. I ordered some chips from them in September but in October they stopped supporting Pakistan.
Sorry to heat that
Yeah its really bad especially for us hobbyist and electronic enthusiasts. I wish they would change their mind.
I am also from Pakistan, that's sad
hahahahaha😂 dirty 🐒
Maybe your country will stop harboring and supporting terrorists. I had to fight them back in 2001 and 2003, and many came from Pakistan.
Your videos are always neat...❤
You also get other magnetic field based current sensors, I believe you may have shown some before, the ACS712 is one and you can get them in various current ratings and you can get breakouts with a screw terminal at one end and header pins one the other. It fixes the distance problem you describe by having the current pass through the IC so the distance between the conductor and sensor can’t change.
Yeah, I believe chips like ACS712 are much better suited for ordinary applications, than that 300A beast.
@@renxula I was more meaning them as a replacement for the shunt resistor ones he says he normally uses. You do get higher current ones that work in the same way (not the ACS712) but I haven’t used the higher current ones. They work in pretty much the same way as the board he showed except the conductor goes through the chip itself.
Wow, I love the little BLDC board. But why dont build a DIY Vacuum Robot with two of these? To control 2x motors. Left and Right
Great video!!
A video on the best usb tester would be much appreciated, should I go for the fnirsi fnb48s or the new fnb58
Thanks!!
Oh very cool. I loved the current measuring one.
CT453 is quite pricy at $4-$7 a chip. There are many other power monitoring sets you can get for under $5 completed. So not sure how they plan to gain ground with their product priced so high.
@@lunacyworks any recommendations for chips? I don't have a project but I'm always interested in reading a new datasheet
Finally a sponsor I can get behind. I love Mouser, they've been my go to since I found about them in the 2000's. They beat Digikey hands down.
For the movement detection Board there is a board for a few cent based on the ic ttp223 that have very very similar capabilities (detecting in a 2cm range…) and you can easily expand the range of detection.
You have also the tof sensor from ST
There are universla breakout boards which can accommodate a lot of smd types (a universal woth long pad (few versions may be needed cos distance beetween pins) and BGA to hole and BGa to solderpad. (The latter 2 are quite expensive, i think 5 pieces of breakout may be cheaper)
what circuit need use, measure 800W aircooled 0-110 volt spindle speed and controll not drop speed or torque if come resist to spindle. cut metal and not drop speed. and can measure speed accurate 0-30 000 rpm
Put your board in a clamp, heat the solder hole from the bottom and use a solder pump from the top to clean the hole out, works fine for me :D
The Bluetooth tracker still isn’t cheap, but much better than the $10k dev boards I saw when that tech hit the market initially! So excited for that to be affordable for all
The VESC from UBOX are perfect for controlling such skateboard. Lots of power for such small package. Would like to see an Electric Bike with them :)
The positioning system looks very interesting.
i wonder how fast it can update the position, how accurate it is and how fast movements can be without weird behavior
@GreatScott! For a future video: How to use an analog/cctv camera with custom overlay ( In this video, it could track a bluetooth smartphone, displaying the tracking information on the video feed)
"But then I remembered that ChatGPT can help you with programming. And thus I’m now a very talented programmer." 🤣 Same here, man!
We all are great programmers now ;-)
@@greatscottlabi am glad i am not the only one! :)
Super interesting, thanks for the Demonstration. LIKE
Y'know, it seems like some solder braid/wick and some decent quality flux would make your life much easier. Those closed solder holes would take a couple minutes (at most) to fully extract and resolder.
Nice video. Just wondering what is the hall sensor on the tip of your teslameter?
Thanks in advance
What are those probes you are using at 12:27? They look great for small pcbs!
Thanks!
4:38 i recomend using a surgical needle. it is so eazy just heat up hole ale push needle in
the motor control board is intimidating, I wish you can make 1 video dedicated to it only and explore all the parameters and what it effects.
Have you ever tried using those SMT to DIP adapters? Seems like a good way to bridge the gap between breadboarding and making a PCB to use IC
4:43 - To clean solder hole, just use wooden toothpick. Heat solder and push with wooden stick.
It’d be nice to see a project which works with zigbee (e.g. Phillips Hue), to be controlled by the hue system (I.e. a non hue light) - or send a signal into Hue
What would you suggest to do accurate absolute distance measurement with a arduino / raspberry pi?
Looking forward to your suggestions
You are a true expert ❤
I love your Videos! This one especially :) Very interesting
Thank you! 😃
speed controller can be used for an awesome diy ebike.
Nice Video again!
Is it just me or was there something off with the audio when you were speaking in your new room? It sounded a bit strange to me. Maybe the room needs some acoustic optimization.
You could have use flux and copper wick braid to open the soldered up holes. It would take 2min instead :)
And if I run outta wick, I just use braided wire 'til the solder is exhausted...
Sir, can you explain how anti kickback works on a cordless drill?
Or you can make it simpler
I hope🙏
A smart person showed that a toothpick can be used to remove solder from the hole. Haven't tried it myself yet, but that's something to keep in mind.
Seems like you're enjoying your new workplace. Great camera angle, though. Good content as always.
Thanks for the feedback :-)
Should make this a series!
Damn, clearing holes is another thing that can be fixed hot iron and enough umpf. Thx for tip
Hi Great Scott.
I have a question for you.
Can you connect a 3 fase AC to get out DC power? I want to make a small windpower charger for my phone/ power bank but I don't know how to get 3 cable's to a full bridge rectifier or do I need to use all 3 cable's or just 2 from the fan motor I will use? Hope to get an answer from you. Regards Dag from Netherlands
Great video.
I was wondering if you could make a video about esp32 as an arduino alternative? Because it is more powerful than raspberry pi pico.
What's the use case of the tracker? Tracking equipment?
13:00 - That IC will be VERY useful in eV's I assume!
4:37 Get yourself a desoldering station. Such as the hakko 472 or proskit ss331. A total life changer.
Try the Tip223 as for a capacitive touch sensor. Much better. The range can be extanted too
Very cool boards! I am especially interested in the current sensor, which seems to be much more accurate and stable than the hall effect sensor I used in a recent project. I might buy a dev board and play around with it :-)
Awesome👍 Glad I could help
Video released 19s ago but comment is 1d old?
But how?
Wait how is it 1day old?
And greatscott's reply is 19hours old?
I think his project is time machine🤔
Build a Theremin, write some code changing frequency of a timer or phase accumulator!
Do you know if that BLDC motor shield can be stacked to have at least two driven by a single Arduino?
Hey I got a challenge for you. Long time viewer here been watching your videos since the FM transmitter.
What if you were to make a power box that could charge using ev chargers and power a house? Maybe not a whole house but part of a house for the essentials (fridge, stove, etc) for roughly 6 hours?
What does the smaller circuit board that you plugged into the capacitive sensor board do?
Hi Great Scott, how are you?. every Sunday I come and check your channel for your new video.
Nice work. Please do you know Good company that you advise me to make copy pcb board from A to Z . Or just making Gerber file with Bomlist ?!
Does @DIWPerks 1000w equiv light a good one, becouse it doesn't have any current control. Can you recommend me an good 100w led driver?
Could you explain or dedicate a video to how you used chatgpt to make the software. Thank you so much
the bluetooth board is fascinating. Basically could act as a phased array radar but with bluetooth
you should use/test one of those x-ray free x-ray sensors/setups.
basically allows you to see things and inside them and through them, well unless shielded with metal or such, or to far away.
actually many modern smartphone have one build in since they cost almost nothing, but in most phones all acces to them for the user, is completely blocked, even just reading it instead only going through a black box meaning one would need to find a way to hack that or to just get their hands on a loose version/development board.
it uses/can use multiple effects such are radio reflection, weakening/degradation of signals, angles, etc. basically like sonar but much more options and it uses radio waves instead.
there are sensors speciffically designed for this so they already form a phased array and handle many pings and such easily,
if you don't know them yet, they are called 5g modules, the same modules which are used to rip off people to get them to pay more for a "new" mobile network so that symbol shows up in their screen despite the actual range of the actual 5g network being so low that in reality you are basically just using 4g or 4g+ most of the time, so are just ripped of and paying way to much for something you in reality don't actually get.
there also are those I think 20ghz or 40ghz radio modules speciffically meant for measuring dept, angle and movement they only measure in half 2d by default. but if you can combine 3 of them 2 horizontal 2 vertical so one in the corner one next to it and one on top of it, or if instead you attach one to a servo or such to move it's position, and some basic computing then you get a full 3d immage which can actually look through things.
it won't work close to as well as 5g, and 5g also has insanely higher resolution, actually good enough to use it like a normal camera, while those 20ghz modules tend to only see resolution up to around 10 cm or such so are more for fun since you can then see people through walls.
would be cool to see normal people actually use those,
even though I think it is logic this is little spoken about, since if many people use it, it might become illegal.
since essentially unlike normal x-ray this allows you to not only look through things, but also inside of them.
very usefull since if enabled on a phone you could see inside your body to see if something is wrong and what using your phone to detect diseases. but at the same time.
this also allows spying on people very easily, and being able to see through clothes.
and would likely cause pannick if people realize their phones have such sensors build into them, but in a black box where it is running but they do not actually know what it does.
ofcource since I am for Free(as in freedom) open source, I actually hate such things being in a black box, so would actually like this since it would force companies to allow people full acces and insight over those modules if they want people to continue using them.
actually is the same as those old raspberry pi radio echo location and triangulation projects, but this is much more advanced and detailed and all sensors can be on one place instead of needing many (3 or more) an triangulation.
Why exactly is Bluetooth involved with indoor location tracking? (Rather than any other proprietary waveform.)Can other Bluetooth devices act as trackers? If so, do they need to implement a particular Bluetooth profile?
Man I was so excited for that indoor tracker, the whole time I was thinking, "It's just bluetooth! It's gonna be so cheap!".... boy was I wrong...
Very informative video
As expected from you bro
Super 👍👍👍👍👍👍
Thanks :-)
I have a project right now that needs that first board. :o
That Bluetooth motion tracker. Is there a way to maybe use something other than Bluetooth, in order to get more range? Could we make it 1km by using 2.4ghz drone style radio transmitters? It would be cool to have long range tracking for a couple projects I’m working on
There probably is but you'd have to use a lot of energy for 1km signal to survive or a lower frequency, which would require a larger antenna. The frequency also affects which objects it can pass through. The device measures the time difference of the signal arriving in each of the antennae, from which it can detect the angle of incidence. It is similar to how a radar works. But I'm mostly commenting, so I can read replies of people who know what they're talking about.
You can look at the UWB technology but on 1km seems a lot. Maybe the use GNSS RTK is a better option
The wireless tracking is interesting...not cheap though!
Cool. Try a video using the LPC2129 uC ?
Tip for everyone who as solder filled through holes: Get a a cheap deslldering pump ( the sping loaded ones that create a short suction on button press) for
Those things are crap and you will learn this over time, use heat and slam or wick.
@@andymouse They've worked for me fine for years. Wick and flux works much better on smd components but those pumps do have a place.
They do...the bin ! lol ! seriously though if you get a good one and your comfortable with it then great but I can do most jobs with wick...cheers !@@clockworkvanhellsing372
It would be interesting if you could try building an RDS encoder for an small fm transmitter
So you just said the 2nd LED alerts to sensed movement, but here (6:49) it seems to be pulsing ~once per second. Does this imply that it's picking up your heart beat? Is it really that sensitive?
I’m gonna have to try that technique of slamming the board on the table to remove hot solder out of through-holes 😂
Wouldnt even just a small foil capacitor reduce the noise enough for the current measure Sensor? Or did you mean you want to measure the noise itself?
Система позиционирования по блютуз, может быть использованна работадателями, чтоб следить за работниками, причем в плотную, чтоб камера (или несколько с нескольких точек) неотрывно смотрели на сотрудника.
