@@EverythingIsHacked They must've known what would happen if they did, haha! The scanner at Lambert/STL who scanned my bag full of Pi Picos was like "That's a lotta Raspberry Pis, what are you using them for?" and I was pretty impressed he knew what they were!

Those cheap barrel jack breakout adapters are downright diabolical. The best you can hope for is to get a totally dead one that's completely open right out of the box, but more often than not, they will act up totally intermittently and not obviously since who would even think something so dead simple could be faulty? They fail short, they fail open, they have some hugely variable voltage drop, loose contacts, bad contacts, loose terminals, bad terminals... Save yourself the headache and throw them in the trash IMMEDIATELY whenever you come across one.
I'm an engineer and I love chess. What a creative way to combine the two! This was so fun to watch I'm sure it'll blow up. You're hilarious too my guy, new sub!
I've been on a plane with very fragile stuff in and have also watched from the window of a plane as the bag got tossed, and of course it was broken in the end. That video was like de-ja-vu, almost exactly, even the seat and the view out the window on that side of the plane was pretty much the same! I gotta say though, compared to what you lost even just one of those times you lost a lot more than I did! I only lost about 50-100 dollars in the end. I'm glad you kept at it and finished the thing- very impressive work! Sub earned!
GOOD LORD I WENT THORUGH THE EXACT SAME THING WITH THE AIRLINE LAST YEAR FOR WRO, i feel your pain more than you could ever know. but hey we both pulled through. the indomitable human spirit coming in clutch, amazing work.
Pro case tip: Harbor Freight makes and sells these hard shell cases. I've taken mine on 12 flights so far and there's no cracks bumps or scratches. they're really tough.
really awesome video, i am inspired by your work ethic to continue after it was demolished twice. The final product looks really beautiful as well. if I could offer some constructive criticism: I think a great deal of your effort and heartbreak could have been avoided if you used a PCB. If you design a custom PCB to solder the switches into (which the relays could live on) you could design most of your connections in a digital environment where ctrl-z lives, and then have robots cut out the board, so you dont have to deal with soldering the switches point-to-point, or debugging the rats nest by hand. This would add structural integrity, because the switches are not going to pop out of the board they are soldered into. You could also mount the acrylic to the PCB with standoffs and i think it would be much more airline resistant. You were inadvertently assembling this like 1950s electronics were constructed with point-to-point soldering
There may be a v2 once I gain some mental distance from v1... Since I was traveling while building this at first, I couldn't reliably get any deliveries and had to stick to parts I could pick up locally. I've also never made a custom PCB, so it seems daunting, but a year later that definitely would have taken me a lot less time and effort!
@@EverythingIsHackedYou could do capacitive landing pads for sensing instead of switches if you do a PCB. Then you can use most any pieces so long as you have metallic bottoms.
@@generalreticent3791 I think the 50+ volts running through the squares/pieces/victim still have to be physically separated from the sensing circuit somehow... You could do some capacitive pads that collapse under the weight of the pieces, but then you've just kinda reinvented switches!
Great video! i just have one issue; Surely you dont need 64 relays to electrify each one of the squares? just have 2 relays (1 per person). Make the entire board grounded, and when the pi detects an illegal move, it sends a high voltage to the one person. Along with hall effect sensors, as suggested by another commentors, a v2 board could be tiny and more alaska-airlines-resistant from the board not needing individual squares. (To be fair, it wont be as impressive haha)
For something like a puzzle setup, once you lift a piece, everything electrifies *except* the single square you could place it. (You could drop it, but then there's a decent chance it'll topple off the key and you have a *really* bad time.) It also wasn't fast enough to respond to a quick tap of the piece with a shock, as opposed to pre-setting which squares are powered.
if you need to move it again, add wooden supports so it doesn't get mangled too much. (cut some osb, put a pilar on each corner and screw everything together) also sandwich the keys with a plate on top and dowels underneath so they don't pull or push on the switches.
There is so much to learn for you, that would have made the building much easier, but your determination and creativity in problem solving is already top notch. I am excited to watch you improve and make great projects!
You seemingly watched silently as the airline employees disrespected your luggage instead of advocating for yourself, let that be a lesson if so lol. Fun bideo 👍😁
I wonder if you could use capacitive sensors to detect the piece locations rather than mechanical switches? Would make it a lot more robust and improve the haptics, but you'd have to make sure the sensors wouldn't get messed up by the discharge. Or maybe a magnetic sensor?
you should add a mode where the shock intensity increases everytime you move a piece, and capturing reduces the shock value. this will create a game of real taser chess, where the more you move your king the more it hurts (as with all the other pieces)
You can done this only with 8 relays by connecting all column in parallel and each square has different resistance with each move we can detect the position of each pieces by comparing first position and trigger high voltage relay according to it. Microcontroller will continuously check each row using analogread and use preassign data and algorithm to make it working efficiently
with joel trying to put the chess piece down and it falling i wonder if you could do something so it stimulates certain muscles. so if its an illegal move it keeps your hand closed so you cant drop the piece down and for normal moves that took too long its just a normal zap. kinda like micheal reeves dab machine. could be kinda cool
That's hilarious that Electro Boom is basically just humoring you. At this point, Electro Boom can probably just rub his feet on a carpet and burn a house down.
One thing I've found with tens is the units HATE being unplugged, turned on, and suddenly turned on. ...they make various high voltage spikes, and modulate the amount of power in the output capacitors by varying the duty cycle/pulse time of the high voltage generator circuit. What this usually means when the pads are glued to you in circuit is power in > capacitor > power out > equilibrium. When you unplug the pads from the circuit (with a relay as you are doing) the tens is gleefully unaware and builds up a significant charge in the output capacitors... power in > capacitor > goes nowhere and builds up > keep adding more power in assuming its going out but its not > suddenly plug in and get 200% pain. For a chess board this is probably fine.
Fun story that didn't make the cut: the relays also draw a bunch of voltage on power up. When I was trying to move to battery power, I had a test script that would turn the relays off and back on every few seconds. Charging the battery while powering the relays when the TENS was also on (I don't know why, it's an entirely separate circuit) caused just enough of a voltage drop to turn the relays off and on in an almost identical pattern. That seemed totally normal until I realized the Pi wasn't even powered on, but it looked like the relays were still running my code!? I was convinced those boards must have some flash memory or something for a while...
Applied behaviorist here, at the beginning you call this "negative reinforcement," but actually introducing a stimulus in response to an unwanted behavior is positive punishment. Negative reinforcement refers to removing a stimulus to a wanted behavior - so true negative reinforcement would be that the board continuously shocks you *until* you make what it considers to be a good move 🙂
Its indeed pretty crazy to shock the shocker himself instead of the shocker himself shocking you. Although he did still shock him and also he shocked back but eb hardly noticed because he was used to it
this looks like fun to play on. *i maybe enjoy pain sometimes* haha. Do hope you make a better one with a proper case that can handle them airplane trips (danm) that hurt to see that bag / inside being scrambeld.
@2:30 should I tell you about reed relays? Saves switches, and probably headache because the whole thing is then mostly non-moving... @6:52 if you use a rotating or reciprocating saw, don't wear gloves. Gloves can get caught in the mechanism and will tear your hand into the blade.
Could you use a camera with a detection software and high contrast pieces to identify your moves? Then a wireless connection to a little Tazer on your wrist, and maybe a dog treat dispenser if you get the best move. I think that might be easier than having every single piece of the board as a pressure plate, but I'll say, this is an extremely impressive amount of dedication, there's nothing you can't do with enough time.
I tried that first, since I'm a lot better at CV than electronics! But it couldn't work well when obscured by arms, in low lighting, and had a hard time telling actual placement vs just getting close to the board.
@@EverythingIsHackedHow about instead of a video, you could have it sort of like how Rubix cube speed runners do, where when they're done they press a button, and take occasional photos, and compare before and after between only two photographs, rather than a constant video. Kind of a middle ground between completely ai based and completely mechanical It'd get rid of the interference with your arms, and you'd tell it when the turn is over That way all it receives is where your pieces are, vs where they were, with little interference from your arms.
every square is conductive and connected separately, so why do you need switches? you can read the current (or capacity?) to see which pawn is being picked up and where it's placed
Correct me if I'm wrong, but could you have used an off-the-shelf board that outputs piece locations and then input the data to a RasPi to control the tens device?
I hate those barrel connectors with passion. Worst part is they can fail and stop delivering any meaning full current but will appear totally fine when tested with continuity meter.
These microcontrollers have a Touch sense technology. You don't have to complete a circuit, it can tell you touched it like a touch lamp. You could detect piece touches that way and actuate the shocker with a single relay instead of this mess
there is the small problem that stockfish isn't perfect, some openings stockfish will rate poorly, so someone playing it might get shocked. This also increases as stockfish runs on less and less powerful hardware.
well... V3 is made entirely of aluminum, brass and copper, build like a brick poophouse and has the bulky switches traded for reed switches and magnets in the chess pieces. Also red relays would do wonders to your space constraints.
I've been looking at red relays for the past ten minutes, wondering what the different color signifies... TIL, reed switches and reed relays! Why aren't these _always_ used instead - because magnets?
@@EverythingIsHacked reed relays are small signal relays primarily used for telecom applications back in the days. They are very small and reliable for millions of cycles. The downside is that they have pretty much no current rating compared to "real" relays. But for tasing someone for a fraction of a second at once, this should be plenty because there s no significant current flowing. Reed switches are just small, magnet activated switches. Just two ends of flat wire, bring a magnet close and they connect. same up- and downsides: small and reliable but low current. But as an input perfectly reasonable.
As an idea why not make a PCB and order it from e.g. JLCPCB. Like 4x4 PCBs and add all electronics, and most important switches directly to the board. Then you can easly disassemble it into 4 parts
I'd never made a custom PCB, and couldn't get one delivered while I was traveling - but eventually it would have been waaay faster... Maybe a v2 one day
Definitely need to practise soldering more. On the display you messed up, a lot of the pins either had too much or too little solder. Otherwise it looked okay. Get a pinecil soldering iron, infinitely better than cheap wall soldering irons and better than even a lot of midrange soldering stations
So, what's your Supervillain name of choice?
