Chickadee wanted to make a scoreboard for cardboard pinball.
I use all analog; relays, resistors, reed switches, magnets instead of arduino or raspi. Chickadee Enginerding https://youtu.be/Qfll8VZnXrY

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.
Is there any danger of burning out the coil of the relay if it is activated for too long? For another application than this pinball machine lets say it is self latching for 3 to 5 hours at a time. Would the relay die sooner?
Edit: Also is there any advantages of this method (Self latching a non-latching relay) vs using a latching relay?
This is so Canadian. I love it
Where can I buy the relay n all the other stuff
I want to use this on a car as a kill switch
Watch out on those Rayovac batteries. Used a shit ton of them sent out over the US and they like to give up and bleed like shit.
self latching? Seal in circuit. Memory logic.
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
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.
hehe, only just saw this vijeo. this lookes like a fun project with Chickadee. Some one has probably already mentioned something similar or you thought of it your self… But I'm going to mention it any how. 🙂 If you connect the LED to ground instead of the "meter" and make a parallel resistor in series with a diode leading to the "meter" you can eliminate the dancing needle 🙂 sure it will draw a minute amout of more power from the battery and is more of a tweak to something that otherwise will work plus making it a bit more complicated 😀 I'll happily draw up the circuit for you if only I have somewhere to send it 😉
Couldn't one simplify this to using the reed switch as a trigger AND a latch, by winding a hold-closed coil around it, connected in series with it? Okay, one might have to run more current through it to hold than with the relay. And, if the triggering magnetic field is the "wrong" way around, it might oppose it…
does chikadee have her own patreon? I could be persuaded to thrown in a dollar if she promises to waste it properly
Great Dad! Nothing better than what you are doing.
Ok so I went over to the chickadee channel and watched, nice job, but I gotta tell ya, that made my ovaries hurt….AND IM A DUDE!
Watched all the commercials to support chickadees college fund, tell her not to spend all .01 cents of my contribution in one place. I will definitely be supporting that channel.
Okay okay. I know this vidjayo is a week old… I did watch it a week ago!
But I just got my empire of dirt hoodie. Ohhhh fuck yeah!
Great quality! Thanks AvE
