By the time your daughter reaches highschool, she will have a better understanding of the technical world and more practical application experience than just about anyone graduating from college, as well as a lot of people already in industry. That, good sir, is the proper way to parent.
Just looked at the chickadee channel. Not only did she know what a needle nose pliers is, she new what DRAWER it was in. I don't even know what drawer, milk crate, shelf, tool bag, 5 gallon bucket, empty beer case my pliers are in.
Did you know you can get a bucket-style tool holder? It's basically a 5-gallon bucket with it's own tool belt. Brilliant! More space for me to lose all the things.
You are actually keeping a non-latching relay switched by continuous coil power. There are actual latching relays which can be switched by reversing the coil current (single coil) or having two separate coils. The advantage is they stay on or off when the coil current is removed or power switched off. They have a physical latch mechanism inside. Though in this application it's a toy, and circuit is probably simpler this way, and like all toys excessively draining batteries seems to be part of the design. They never provide the darn batteries for Xmas morning present opening either.
I wonder when the term "F-bomb" will become more problematic than the actual word. I can already imagine it getting you in trouble in places like airports when uttered the wrong way.
You inspire the crap out of me to make sure my two daughters are just as interested in tech and engineerding as I am. Thank you for sharing these fun projects.
You should be teachin the kiddos vacuum tube circuitry! Nothin makes a more well rounded adult than a few hundred 500VDC (700CVDC) zaps in early childhood. You nevermind those twitches.
You don't have to be all that old. I'm in my 40s and let me tell ya.. I know what those zaps feel like! Had old ass console TV I had to learn to fix because I wasn't getting a new one. Only reason I got that one was that my dad found it in a van he was taking to junkyard. So imagine a kid between 7 and 15 learning the HARD way how to fix his own TV! Lol I still twitch a bit! But ever since then I literally laugh when hit by 110 and 220 to this day.
Just watched and subscribed to chickadees channel. Didn't realize you made her one. Love the pin ball machine video, made my day and also made me smile. Also the grammar fight in the comments cracked me up a bit.
The last part really helped me.. Glad to know it’s not just me.. I have no patience for ignorance, rather it’s a chickadee or coworker. The little ones can’t help it, but some adults surprise me they get to work in one piece.
This is awesome, my dad showed me this (self latching relay) when I was a little kid. Only the relays we had were huge and unshielded so you could actually see them work. More bigger more better!
This is great, my 2.5 y.o DD and I watch chickadee engineering together. She loves it, less pepper pig more chickadee engineering is where I'm coming from. Many a day spent wrangling pixies and many a blown led prior to the discovery of le resistance when I was a wee tacker. Love your work mate 😆
I thought you were going to explain this so that your daughter would understand. I figured that at that level of explanation, I’d understand too. I didn’t. LOL
I agree with you, I don't understand it either. He may be practicing on us to fine tune the explanation for her. We'll have to see the final video over at chickadee later.
I'm in the ladder half of my junior year for my Mechanical engineering degree and I plan to do the same with my some when he's old enough. This is something everyone should be taught.
So that was a real treat! You and chickadee and a cardboard machine! I have the privilege of hanging around the campfire with Ben from the cardboard tech instantute. Pretty cool aren’t they. Be well
Man! I’m in the HVAC business, if you were an instructor in my field you would have guys lining up at the door to take your class. You are a funny guy to listen to!!
My 12 year old son that already has a foul mouth. 1 our of 4 ain’t bad! Has been watching your channel with me. He said to me I like that guy, he is an adult version of Dr. Seuss. Lol. Now I can only picture you as the cat in the hat. Thank You for all the great informative lessons we are always picking up something new here.
This is no mere fluff when i say your kid is well armed in the brains and education Dept. So good to see you being a good Dad and doing just what your doing. And as I write this I am suffering through hearing a couple bulldaggers sing about a car. GTG
As a kid I've had a pinball machine. When you hit targets the ball made contact from the target to the base, closing the circuit with a simple electric motor that turned the pointer
The circuit you are describing my friend is called a holding relay latching relays are mechanical devices that stay engaged after the power is removed holding relay stay in as long as the coil is energized
Love it. Did something similar for a start button on a project car. About 3xs the $ of buying the kit...but way more satisfying lol. Can't wait to see it installed.
Hi I'm looking forward to the chickadee version. I have engorged both of the chanals and have noticed a couple of Ave mentions on other sites that I have subscribed to. Keep up the good work
Please note that there is a distinction between latching relays and traditional control relays wired into a sealing circuit as shown here. Latching relays use two separate coils or one coil that is polarity-sensitive to actuate the armature in both directions. A spring or magnet holds the armature in whichever state it is in when power is removed. An ordinary control relay uses one coil and a spring to actuate the armature. When power is applied, magnetic forces overcome the spring tension and move the armature. When power is removed, the spring returns the armature to it's resting position. Not an important distinction for most people, but if you walk into an electrical wholesale house and ask them to sell you a 'latching relay', you will be handed something very different than the relay shown here in this video.
Yep. I've got a paper somewhere that says I was taught that stuff in pixie wrangler school. But... when I was 10, in grades 5 & 6, I was fascinated with electricity. My poor dad was as unhandy as could be. For some reason, I decided to build a unique project - an electric door. I salvaged some relays, momentary and magnetic reed switches from demolitions, dumpsters and the local telephone switch building trash. (This was the 60's). I found a 120 VAC gear motor in a junked watch display behind a drug store. With many false starts, I wired it up so that, by tapping a button, it would open my bedroom door and stop. Or close the bedroom door and stop. The control circuits were mostly low-voltage - I think all the relays had markings of some kind. Somehow or t'other, I got it to work, and made the non-latching relays latch by doing something like this. I hadn't yet received the benefits of a technical education, and nobody told me it was impossible. Amazing to recall now, this thing worked for years. It never stank, smoked, caught fire or maimed anybody (I put a rubber cork in the driveshaft connection that would slip if the door jammed, just in case). The original actuation was by momentary contact push button. Then I saw an advert for a "voice-activated switch" in the back of Popular Mech. magazine. So I took some paper-route earnings and ordered a couple - $6, big money for me then. Those actually worked, and so I had an "Open Sesame" door. My parents were puzzled at times, but to their credit, they let me go ahead, and never insisted that I should get an adult to help. I'm sure there was a lingering fear that I'd burn the house down.... Probably the best compliment I've ever received was at a Christmas party held by my parents. A family friend who was a for-real electrical engineer was told about "the thing" by my mother. He insisted on having a look. He came upstairs, watched it cycle, inspected the mechanism, took the cover off the relay box and looked over the kludged-together electrics inside. Then he shook his head and said, very slowly "Well I'll be go to hell." Years later, he told me that he'd figured my mother was pulling his leg. I almost wish now that I'd saved the main parts of this device because looking back, I can't imagine how it worked at all using the mish-mash of junked parts, let alone work reliably for 7 more years. All switches and relays and motorized mechanical "logic" - somehow or other.
Ave, just saw they have new impact drivers out, they decided they could quiet them down by filling them with shmoo. Calling them oil-pulse drivers. I didn't see DeWalt, but most of the time others are there, Makita, Milwaukee, rigid, and Ryobi. Can't wait to see you tear into one.
I think you could accomplish similar results using a d-flip flop using some standard logic gates, then use the adc of a micro controller to read in your voltage and use arithmetic to compute the current values as well as display those values proportional the current. It would require a more sensing circuitry but it would be a system that could be expanded on infinitely! As someone who has worked with power electronics it just hurts to see wasted energy. This is a very practical application or micro controllers and people could learn a lot from such an experiment. Keep moving forward, and avoid sniffing any of that magic smoke ;)
Old school relay logic. That brings back memories of yesterday. Or as they say now " back in the day". Lol The prior video with her putting the unit together + this one = more dad & daughter videos to the pin ball game final product. Plus we can see how long you can last without an expletive. LMAO 😹😹😹😹😹 I slip them out in front of my 3 yr old granddaughter and my Son says " really dad ". Oops.
I did something similar with a BMW X5 starter relay so I could have a battery isolater button on my car for track days. Isolates the battery and alternator so is a complete electrical kill switch.
Nice idea! You might want to add a snubber diode to each relay coil to prevent reverse current from arcing the switch contacts when the relay is de-energized. Just put one in parallel with each coil with the cathode (marking) end toward the positive voltage side. The diode will shunt the inductive spike created when the magnetic field collapses. A common 1N4001 should do fine.
Reed switches are interesting in their own right. Seems simple, switch, but how their orientation to the magnetic field's lobes impact the activation is more complex than expected.
All this verbal restraint around little Chickadee must be due to the Better3/4 wanting to present the world with an offspring that can be expected to be able to pretend ladylike decorum in certain situations. Like learning real english and french BEFORE shop slang.
+1 for proper parenting. My daughters both have unlimited access to my shed. I hid the keys to my band saw, but no doubt they'll finger it out eventually...
Have some heavy duty neodymium magnets if you would like a few to play with. Forewarning though if you put your finger between it and something magnetic it will give a good pinch
The other IC i have been playing with recently is the LM3914 In your current circuit, you could replace the ammeter with a resistor, connect the input of the 3914 across it to give a dot or bar display In either case (ammeter or 3914) you could connect a capacitor to stabilise the reading
Yeah I felt bad one one of the chickadee vids I left a raw comment. Then remembered edit button. Figured she so darn smart she probably is reading already. But I did correct it quickly.
Have you considered adding a small filtering capacitor (I think that's the appropriate term here) between the LED and the ammeter to stabilize the needle so that it doesn't twitch so much?
By the time your daughter reaches highschool, she will have a better understanding of the technical world and more practical application experience than just about anyone graduating from college, as well as a lot of people already in industry. That, good sir, is the proper way to parent.

Sir, you speak the truth, the whole truth, and nothing but the truth!!!😱😱. Kindest regards. Joe.
That’s if she can understand a word the bumbling bafoon is saying.
She'll also have a healthy beer fund from the monetization of the chickadee engineering channel, which by the way, is adorable.
I recon she will rebel and do like art or fashion or something
Just looked at the chickadee channel. Not only did she know what a needle nose pliers is, she new what DRAWER it was in. I don't even know what drawer, milk crate, shelf, tool bag, 5 gallon bucket, empty beer case my pliers are in.
Did you know you can get a bucket-style tool holder? It's basically a 5-gallon bucket with it's own tool belt. Brilliant!
More space for me to lose all the things.
A normally closed momentary push button would be cool to reset the game and have the main power switch for storing it.
Save that for the next scheduled upgrade 😀

Only two F-bombs in this one, I can show my daughter. Nothing that she hasn't heard at school, so she tells me.
Those teachers ought to keep their F bombs in the staff room
Its not the teachers its he other students
@@ikki7817 my comment was a joke ;)
I wonder when the term "F-bomb" will become more problematic than the actual word. I can already imagine it getting you in trouble in places like airports when uttered the wrong way.
@@ikki7817 /r/woooosh
You inspire the crap out of me to make sure my two daughters are just as interested in tech and engineerding as I am. Thank you for sharing these fun projects.
90% for beauty school or for Haas payment..lol
Nice to see a dad taking interest in his child and her education. She'll always remember when her dad opened the world of engineering to her.
You should be teachin the kiddos vacuum tube circuitry! Nothin makes a more well rounded adult than a few hundred 500VDC (700CVDC) zaps in early childhood. You nevermind those twitches.
He's not old enough to know vacuum tube technology.
I lit myself up on old tv's 45 years ago. I'm still twitching from time to time. OR maybe that's just restless leg syndrome ;-)
You don't have to be all that old. I'm in my 40s and let me tell ya.. I know what those zaps feel like! Had old ass console TV I had to learn to fix because I wasn't getting a new one. Only reason I got that one was that my dad found it in a van he was taking to junkyard. So imagine a kid between 7 and 15 learning the HARD way how to fix his own TV! Lol I still twitch a bit! But ever since then I literally laugh when hit by 110 and 220 to this day.
Born in the 50’s, my dad said: (1) ALWAYS unplug, (2) that’s a capacitor don’t touch, (3) have fun, find the bad tube.

This guy is such a rocket surgeon! I had no idea what he was talking about , but still watched the whole videos!!
Chickadee better have a video installing this. Love what u did making her channel. Hopefully soon my daughter will be in the shop with me too.

AVE .. Eric O of South main auto wants you to do s teardown of his HF cordless impact it has one year daily use
Tell Eric to send it to him! AvE will do it! I'd like to see it. He's not exactly easy on his tools.
I'm sure she'll get it, even I basically understood what you were on about!
I wish your daughter great success, because I can't share many of your videos with kiddos I'm trying to teach, though it'd do them some good overall.
"Simple with an Arduino, some ones and zeroes and some jazz hands" - holy crap that was the funniest explanation of microelectronics ever.
Hope Christmas was happy and new year also!
Resistors can be used to limit current or even better in this case used as a voltage divider.
Please note that there is a distinction between latching relays and traditional control relays wired into a sealing circuit as shown here.

Add a cap to keep the meter from jumping.
The meter bouncing around is a feature. :)

Ave makes a vid for beginners i still have no idea what he is talking about just such a good voice to listen to while im drinking hahaha
I use latching relays frequently in the access control industry. Just need an DPDT and a momentary reset button.
This is exactly how I start circuit designs. They dont get a real schematic until the bean counters get involved.
Teach your children well...or at least, teach them to make money on TH-cam. Love your videos, please keep em coming.

This is so Canadian. I love it
I used this topology, with another relay in the output (instead of the led) to isolate the input from the output.
I did something similar with a BMW X5 starter relay so I could have a battery isolater button on my car for track days. Isolates the battery and alternator so is a complete electrical kill switch.
For the winning relay- connect it so that it vibrates on and off. The on turns it off and the off turns it on.
you could also use a normally closed momentary push button as a "reset" button so you don't have to kill the main power every time.
Under your tutilege the Chickadee will be smarter than I am by... Probably tomorrow! 😊
I'd add a 0.1 uf cap across the reed switch so it wont ARC every time it opens - just like a "condenser" protects points in a cars ignition.
I like your coffee stirrer, Which adds more flavor a standard or metric wrench?
Nowt wrong with Papercad,
Never ever crashes.
Mine does it wads itself into a ball all the time and I have to start over.
Josh Crutchley does it also throw itself into the ‘art’ bucket too?
but it doesnt like weldment drawings....busts into flames time to time. had to reprint drawing for the shop as they burned down xyz times :D
Sour Patch Kids are amazing man- she has great taste. Can’t get them anywhere in the UK anymore; life’s never been the same since.
Even if it's a simple circuit, I still prefer and enjoy more seeing you actually make it rather than through the magick that is computerlation.
Nice idea! You might want to add a snubber diode to each relay coil to prevent reverse current from arcing the switch contacts when the relay is de-energized. Just put one in parallel with each coil with the cathode (marking) end toward the positive voltage side. The diode will shunt the inductive spike created when the magnetic field collapses. A common 1N4001 should do fine.

kym copyriot I see what you did there, LOL!
Awesome Dad ❤
May I suggest a double pole relay?
One pole for the score and latch the second pole for the LED with it's random current draw.
love the PB300
Sweet little go circuit! :) Would a cap on the meter snub the movement?
new mic. love it. hear you swear in much higher quality (and only in my right ear equalize your audio)
Finally, something industrial beacon !!!
My right ear enjoyed this video
Have some heavy duty neodymium magnets if you would like a few to play with. Forewarning though if you put your finger between it and something magnetic it will give a good pinch
looking forward to the bar tending robot. Is it coming soon?
You are a brave man! 😁
And the next time she wants some sort of scoreboard, try the CD4017 ;)
yay for the 70's my favorite chip too, goo the police chaser lights.
The other IC i have been playing with recently is the LM3914
In your current circuit, you could replace the ammeter with a resistor, connect the input of the 3914 across it to give a dot or bar display
In either case (ammeter or 3914) you could connect a capacitor to stabilise the reading
Dad O the fuckin year, this is an awesome project!
Oh man she's got a taste of the big bucks!! Next thing you know she's going to be posting Amazon affiliate links! Lol
Yeah I felt bad one one of the chickadee vids I left a raw comment. Then remembered edit button. Figured she so darn smart she probably is reading already. But I did correct it quickly.
my right ear enjoyed this alot lol
put a capacitor (1µF should do) paralell to the LED, this should reduce the needle swing a little bit
Your a good man charlie brown.
Have you considered adding a small filtering capacitor (I think that's the appropriate term here) between the LED and the ammeter to stabilize the needle so that it doesn't twitch so much?
