Hey guys, believe it or not, but this video got finished right in time. In time for what? Well my birthday party will start in a few hours, if you wanna call five or so people a party ( There are reason not to meet in larger groups at the moment, right?). So in case you liked the video and wanna buy me a beer ( or two), here are two ways to do that:

Well happy birthday !
Happy birthday my man
Happy birthday!
Happy birthday.
Cheers!
I once took apart a blender hoping to find a speed controller. Instead it had only two speeds. Full AC and half AC with a diode. Loved the cheap solution but no speed controller for me!
Edit: Also, happy birthday!
The motor might have been noisier with a diode than with a triac
I have an old hand mixer that has a four position switch on top of the handle for off, low, medium and high. All of these positions have a diode in series by default. Under the handle is a finger operated trigger that enables a "turbo" mode by shorting the diode leads. It is probably 25 or 30 years old. It doesn't really say turbo, it's unlabeled. Didn't even notice it being there until I disassembled it for cleaning and new lubrication because it was getting a little slow when it was cold, until the old grease got warmed up. My wife and daughter had never noticed the trigger either.
My blerder has like 7 diferent resistors xd
I am an electronics engineer with 40+ years on the job, so your content is not new to me. But I enjoy watching your lectures anyway because they are the finest explanations of how electronic things work that I have ever seen. You could teach at any technical school, I think. The way you draw the circuits a bit at a time, and how you lay the drawing out indicates that not only do you really understand, but you can explain it well. Well Done!
*Yes! I want more videos like this.* Being a subscriber since day one (or two maybe) I really like this kind of videos like the old ones on this channel.
I appreciate much when you do your thing and explain what's going on rather than just watching you doing stuff. You are very good explaining concepts and functions.
Indeed I cannot agree more
These are my favorite videos where you explain the circuits. The repair videos are fun to watch but these are the videos where we can learn something.
I bought one of those bread machines at a Goodwill for $6 - there were several more there. Matthias Wandel used the 120V version of that motor for his latest dust collector.
Great video, would love to see more like it (especially the idea of taking one junked item and turning it into a more useful general purpose platform.)
I've learned my way around electronics over the past couple years and you've played a role in that. You've never explained things so clearly and that helps a lot. The hardest part about being a teacher is it is so easy to skip things that feel common to you, but that will lead someone to being completely lost without. You're getting better and better at this!
Thanks TPAI, haven't heard you get down in the weeds like this in a while.
I second this. Lots of great learning here that can be used for diy projects.
Thanks for the detailed video. After watching your old motor speed controller videos I built a temperature regulator for my AC soldering iron. Its manual but serves the purpose.
These are the videos that brought me to your channel. I enjoy your repair videos but I'm glad that you are still doing ones like these. Keep up the good work
I follow your channel mainly for the education and im in the same business as you.
I repair anyting i can find and i will never stop making garbage sing in my shop!
Happy birthday from northern Sweden!
Halfway through the video, Are you about to make a multi-speed bread maker? Only kidding. great video as always. Keep up the great work.
Hi there, Please consider make a clip or series of clips about Treadmill components like DC motor and Ac motor for lifting and control board and display unit circuitry and specially about trouble shooting of these components. You are just amazing. You are my most favorite. I have all your episodes so far. Keep going never stop.
I prefer the repair videos but ones like this are also worth your time, I think. I still watch most of them.
Also, happy birthday!
A very good explainer piece to camera describing zero-crossing and Arduino control! Well done indeed...
I like this type of interfacing simple electronics to electrical equipments videos.
Now I'm planning for controlling a cheap plain heater as a premium heater using this method by including a temperature sensor and display. Thanks a lot
As a hobbiest, I'm really lucky found this vid, simple project & nice + clear explaination.
Thank You
Yes this is gold, please more electronics basics. Few others have ISRU down the same way you do and can explain in the same depth!!
I decided to hookup a dimmer switch to my cheap harbor fright hand drill cause it was basically off or full speed. Cut one wire half down the power cord and wired the dimmer in series. Works like a dream. 600 watt slider dimmer found for a dollar at a resale shop.
Your other video got 1 million views because you are smart and easy to listen to.
Keep up the great work.
Your channel is the perfect mix of the concepts you described at the end .. really enjoyed this classic TPAI episode as I do all of them.
Aw sweet it goes to 11!!! (Not sure if you’ll get the spinal tap reference) but happy birthday!
Get back on the crane, man!
@@TechGorilla1987 cold and rainy here. Not really a good time to spend outdoors, been working in the shop
@@DieselCreek I understand that now for sure. I woke up and it was 40 and started to rain. South central PA here.
Nice seeing you You Hear
Would love too see more of the auto car semi
I always enjoy your videos especially the electronic items with circuit diagrams together with your explanations. Always clear, understandable and inspirational. Thanks for your efforts
Some of his exposition is a bit round about. What he's saying is all correct. But his way of laying it out can be somewhat convoluted at times. I personally think there's better sources of triacs and relays than defunct bread machines. At least today. After the apocalypse we might have to be less choosy then.
Hi TPAI, yes please keep making this type of videos too. Always wanted to learn about electronics but never got the chance. Thanks again!
Great video for those who understand basics and want to learn more. Well done.
I was laughing when you talked about the diac-triac (dimmer circuit) versus using a micro controller. I was thinking that same thing when you brought it up in the video! Thanks for all of the interesting work you do on this channel. Happy Birthday - Alles Gute zum Geburtstag.
I found this video very interesting, as someone of advancing years who has just started to learn how to use Arduinos.
Interesting yes, but do keep in mind what he says about the code examples being crude and simplistic. Using delay() instructions is real bad practice that will cause you all sorts of misery in a real project. Okay for a quick slap-up demo, not okay for a project. Learn how to use interrupts and/or do comparisons on millis() for all your timing needs and you will be a much happier programmer!
@@sootikins "Advanced", to me is 90+ ... we are best-agers! ... also forcing myself to get more familiar with Arduinos. My approach until now: use sb. who is 70+ to program my stuff so I can focus on the engineering part ;-)
@@f.d.6667 I'm no kid myself but you are more "advanced" than I ;) I wasn't criticizing you, I was more just encouraging you to learn to program well since you said you are learning to program. No need to learn bad habits! If you are/were a successful engineer you won't have trouble learning to program well if you want to regardless of age.
This is more interesting than only repairs! I miss your old PSU tutorials!
Nice. I did something very similar to this to extend the life of my Ebike's batteries. I hacked apart a window AC unit that wasn't hardly cold any more then I used the electronics to turn on and off my Ebike's charger with them. The benefit is the window AC had a timer so now I can just give it 2 or 3 hours after every trip and it keeps the batteries at levels that should be good for many thousands of uses.
Tough one for me this time as a electronical chimp, but still watched it completely in hopes of learning sth. Happy birthday
Your videos shall be presented in the power electronics courses in universities. I mean, what you are doing in your videos is highly practical, compared with the schematics presented in university, that are good to learn the theory behind the circuits and that's all.
Thanks for your awesome work and keep it up!
I’m truly amazed by how good your English is especially when considering that you live in Germany. Thanks for another fantastic video and Happy Birthday!!
I am one of those older guys you refer to in the video. Your argument presupposes that durability and repairability can be built into electronics of today to be the equivalent of the electronics of times past. But nothing could be further from the truth, at least in practice. The reason is simple: for a piece of equipment subject to field use, the durability of sensitive electronics can only be achieved by potting, which makes those same electronic virtually unserviceable. By contrast, the hard circuits of the past could survive most banging about and could also be accessed and easily repaired if or when it ever did fail.
great video, I like it that you keep it simple but don't avoid technical terms and a very detailed explanation on how you did things and what to think about.
You should've held this back for Halloween, it's got super scary things. That terrifying fan and then the thought of a hot main on my laptop's shield.
Great vid
PLEASE, keep doing these kinds of videos as well as mechanical ones. You have a great channel, please keep going!
I have been dipping in and out of your channel for a while now and have enjoyed your videos but this and your arc welder improvements have made me become a subscriber.
Yes, tutorials are interesting and informative... and fun!
wonderful video! i rely like the thought of hunting down scrap worthy "broken" items on auction sites and not just look at the local scrapyard (which is way more hit and miss) . don't get me wrong though, your reparations are incredibly inspiring regardless.
Much respect here from Greensburg Indiana. Thank you for sharing my friend. I always appreciate teachings from someone that knows.
This is a fascinating mixture of tear down and project video.... with a good chunk of tutorial too.... Wunderbar!
Micro Controller + Poti + Fein Drill = ideale Voraussetzungen für eine Ständerbohrmaschine
This was very useful. Ive been trying to figure out the circuit of a similar device and this helped ALOT!
Happy Birthday TPAI. Thanks for all the great content. God bless you.
Nice to see some power electronics content. I always learn something. Need to find that bread maker circuit board I salvaged 😀
It's great to see a "traditional" TPAI video again!
Thanks for the zero-crossing stuff... I'm trying to learn about this right now.
I've got an old wasing machine board with an AVR, an ICSP header and loads of relays - maybe triacs too... I've still not got around to doing anything with it... maybe this video will finally get me to stop being so lazy.
I love your tutorials. You inspired me to buy an Arduino and couple my knowledge of machine learning with EE and ME applications.
Great video! Your videos are always interesting to watch! Especially the repair-a-thon ones! Also, I love the fact that you leave it as a proof of concept and not a finished project, it leaves you to think of how it could be useful to any project you might be working on or a solution to something you can't quite figure out just yet!
Great video. I enjoy the repurposing of old electronics and tools.
lol, honestly, I was impressed the second you put power to that motor, I could tell it had a fuck tonne of torque instantly.
cool.very clever engineer, bringing back most valuable tools
I would like to document my demand. I appreciate the evolution of your channel and love the new content, this video incorporates a lot of the elements that were present more frequently when I discovered your channel, like the SMPS, welding, and general electronics videos I hope creating this content is as enjoyable to make as it is for us to consume.
As always, thanks for sharing!
Hello TPAI, Yes, keep making electronics tutorial videos, a big reason I'm a long time loyal sub. I like the repair a thons as well. Great content, your channel has always been good. All the best from Oregon, C.
Happy Birthday good to see you back on the electronics. Love to buy you a beer but due to everyone's favourite virus I no longer have a job. All the same hope it's a good day.
Loved learning these techniques/ideas in such an interactive way, would enjoy more if you can fit them in!
the video is very interesting and explained at the right speed even for those who do not know English well (I am Italian) from what little I have understood about Arduino, the problem is not to interface it with the outside world but to understand how to use the instructions to do what we you need, and you can't learn this if you don't bump into it and if you don't have someone to open your way.
Your channel is very interesting, since I've been following it for at least three years and I don't miss any of your videos and this new development is also on the right track, at least in my humble opinion.
Hello, to the next videos, happy birthday, stay healthy and celebrate via skype!
Very helpful video. I have a few projects that need speed control over largish motors coming up. Thanks.
Used bread machines multiply like rabbits at our thrift stores in my area of the US. Each week, there are 4 or 5 more for under 5 USD.
NICE! Any kind of electrics / electronics in thrift stores is great. In the UK everything has to be safety tested by a certified electrician and our "Charity Shops" (thrift stores) just can't afford that.... so anything electrical is RARE.
@@edgeeffect I can understand that, really. 220-240 volt appliances would likely hurt a lot of the dolts I see walking the thrift shops here. That said, I am the kind of guy that LOVES to have others used stuff. People that buy really expensive stuff and just toss it. I got a pressure cooker new that way. Fantastic item!
Not a very fancy solution but I mixed ceiling fan pull switch with a dehumidifiers blower for my basement exhaust ventilation, this gave me 2 speeds. The original controls for the dehumidifier were very close to the bread board in this video. I just wanted to keep it simple :D. Great video maybe Ill convert my approach to this in the future.
A really great tutorial for beginners like me, well done, thank you
Well this answers all of my homemade CNC questions.
I saw you over on the channel of that crazy Canadian, showing off, I mean really showing off, those new Japanese tools... Hmmm. How the heck are you doing?? Every time I go to pick up some Wertstoffhof 'find', meine kleine frau grabs my arm and drags me away...today, several big RC cars, with motors, universal joints, differentials, springs, bearings, all kinds of take-apart and have on the shelf goodies ... but, that's the tradeoff we get ;-)
Too bad that COID id keeping me home... I need to dig into my LED stuff and send off some LEDs of different sizes and colours (mostly surface mount, hope that's ok).
Keep well, have fun!
I reall like your tutorials and this one is no exception.
The one about groundding was actually really helpful, as it was the first time I could fully understand the need for isolation transformers.
If I knew what u forget I would be a genius.
Great vids.
Love them.
Your blessed thank God for it.

Yes, sir . Please we need more vedio about the concept not finshed ideas.

thank you for all the effort you put into it.. its motivating....
3:34 I am curious what does the "HELL" program do!
ps. I know it's not the "brightest" joke ever.
Hell means Light or bright in german.
Probably for less brown i guess.

No, It's getting dark/dunkel here...
Excelent video. Maybe more videos explaining these kind of circuits or reverse engineering these circuits from different electronic devices.
Love the tutorial style vids! Please keep them coming
i wish i could understand a lot of this but i still enjoy it..Happy Birthday from Australia!
These videos are so cool. Please keep making both types! The way you explain things is so intuitive and easy to understand. I really appreciate that you just give us your knowledge. I would love to see more like this
Happy birthday (alles guten zum geburtstag :D) and yes I really like these kind of videos to fresh up what I once learned as electric engineer but forgot after 20 years of software devlopment/architecture/project leadership :-)
THANKS for bringing us to roots of DIY!
You might try to make a closed loop speed control circuit by using a reflective IR sensor as a tachometer and feed it into a PID algorithm in the arduino to keep the motor speed constant under load. You will also need a zero cross point detector in order to actuate the triac for the speed control
Ich habe zwei 9 Euro 2000 W schaltregler bei Amazon gekauft. Hat niedrige Frequenz aber kann definitiv 2 KW regeln. Eingebaut in Box für früheres 220 V / Akkuladegerät. Sehr gut.
Very good tutorial! I appreciate the nicely drawn diagrams along with descriptions. It might be useful to do a tutorial on the triac alone showing i-v characteristics. Triacs are unusual devices for tinkerers but so common for power control so that’s really useful.
Very interesting blend of types of videos! Don’t change
Hey, the EEVBlog forum is down at the moment but when it comes back online come find my thread about the Craftsman CMEW020 Jointer. It came with a U2010B controller. I've reverse engineered the circuit. I haven't published, but have designed and etched a single sided prototype that incorporates the datasheet reference design and the circuit from the jointer. The kicad file for it is a bit of a mess but if someone wants it, I'll try to clean it up and publish it.
This is the simple universal motor controller you are looking for. It is currently manufactured, cheap, simple, and uses back emf and a current shunt for the feedback circuit block, no tachometer winding needed. Setting it up for any motor just requires picking a shunt resistor that will have a 250mV drop across it at full load. For instance, my Jointer uses a 50mR shunt made from two 0.1R ceramic wire wound resistors in parallel for a max load current of 5 amps.

Fantastic video, and all the safety information is great for noobs like me!
Great video! Your repairathons are great, but I love to watch a mix of this kind of projects too. I really like to see practical examples of stuff I learned in engineering school but forgot as they wouldn't show how to use them in real applications.
Its very cool to open up something and hack it i wish you publish more like this
HAPPY BIRTHDAY TPAI.
Excellent video and a good sprinkling of main voltage warnings... very sensible and you will get to see many more birthdays! Congratulations 😀🎂🎆
now do a DIY soft start!
That's what the light ramping up was.
great video and an very nice tutorial, thumbs up.
Happy Birthday to you and thanks for all videos
Now I know what to do with all of those free breadboards I get from Adafruit!
Looks perfect to control the temperature and venting of a 3D printer enclosure.
I love prototype solutions and ideas
@TPAI
HAPPY BIRTHDAY !!!
Nice project
Happy Birthday TPAI!
Germans, the best of the best in technology! Keep up m8!
Yes, this type of video is quite educational _and_ interesting!
Happy Birthday! All the best wishes and many happy returns of the day!
I admired your work!

Sadly as a programmer i have to correct you
at 2:50 you said "two variables [...] are defined" but it's false ! ah ah !
You defined the variable 'microsec' but you DECLARED the variable 'val' as there is no value associated in the declaration :p
Joke aside, really nice work, thank you for sharing all your work and passion.
Thank you very much, that's really motivating.
Anyway, see ya in next episode
An average french viewer :)
ps : Happy birthday :D
Cheap speed controls can be had on ebay from RC cars too!
Thanks! I appreciate this kind of contents, and would like to humbly suggest you adjust the level of difficulty/explanation in either direction: as it is now I believe it is either too 'easy' and already known for part of the audience and too hard and underexplained for the rest of the audience to follow. Thus, not really beneficial to many of your viewers. Which way you go is of course according to your goal here.
