Please rename it. You were so close to the perfect Japanese language joke!!! Please name it: Tamago Ochi 卵オチ 卵 Tamago = egg 落ち Ochi = a noun that can mean final result, but when written in the katakana as オチ it would mean punch line and the noun comes from the verb 落ちる ochiru that means to drop The name would be a punch line about checking the final result of the dropping of an egg, while being a wordplay on Tamagotchi because it looks like it. The tiny difference in pronunciation would be that Tamagotchi is pronounced with a small silence between tamago and chi, while for your egg you would speak the O sound twice as long without silence.
as soon as you mentioned the code being open-source, my mind went to integrating it into games. could be as simple as as "gather your friends around, whoever can chuck it at the ground the hardest wins" to something more complex like making a realistic cooking mama minigame where you have to find the right amount of force to hit it against something to "crack" it without just full on breaking it. Could also maybe make a golf game where the harder you hit it with/against something, the farther your golf ball goes. EDIT cause i just thought of another idea: race through an obstacle course while trying to keep the egg's forces at a minimal level. challenge yourself or friends to minmax speed and gentleness!
I'm gonna add more of my ideas to replies instead of continuing to edit my original post over and over. that said, of course i have another... IDEA: Egg Chicken. You read that right: Egg. Chicken. Who can exert the most force on the egg without breaking a certain threshold? designate a threshold beforehand, and everyone takes turns. you lose if your number is lower than the person who went before you, or if you go over the threshold.
@@joosh.efor egg chicken I think it's better in elimination rounds, where it gives you a score to hit, you have 3 hits, best one kept, and the person with the lowest score gets eliminated. Though doing it in reverse, with the highest score wins is interesting too, because worse players get to play more which acts as a correcting mechanism.
Not using the exact force but the direction, you can fast juggle, throw the egg between your hands and see how many you can do in a set amount of time, you could also do shakes, rep counter by attaching it to a belt or barbell. Step counter is also an obvious choice.
How about a baseball shaped object that athletes use to increase their throwing speed. Could receive a lot of useful data from different types of pitches as well. I could honestly see something like this being implemented if it has not already.
This is brilliant Stefan! I'm already looking at how we could implement an egg drop competition using the smart egg in my local IMechE region as a STEM event for school children, university students and maybe even professional engineers! Being able to visualise the data and the OLED screen will be cool for children. It'll add some interesting maths for engineering students and potentially tough competition between groups of professional engineers.
Over the past couple of weeks I've been making a slightly similar project myself in the form of an acceleration & speed sensing baseball to improve my throw. Something I really can't stress enough is the convenience of a wireless dashboard! It's been significantly less effort just having someone with a phone watching the live graph and max values than having to take an SD card out to plug into a computer every time! Loved the video, concept, and design!
I think it would be interesting to find a way to non-destructively simulate point impacts. Even if you have an overall slower fall, when the impact is concentrated onto a small point the egg will still break. I imagine a primitive version of a resistive touch screen. I think this would be a great addition to help grade low impacts
this is genuinely such a great idea! I remember doing egg drops in elementary school and been high school, and the results were obviously very binary (and hard to clean up!). This seems like such a good way to fix that, while still keeping the spirit of the challenge. Good stuff!
This is such a nice and cute idea with a lot of scientific and maker aspects along the way. It's a super cool idea, and the collaboration - although I didn't know William - made things much more fun.
The dynamics and engineering of braking an egg are so complex that an accelerometer doesn't give enough data. V2.0 needs an array of tiny strain gauges measuring the force repartition on the shell of the egg
Omg, I need this thing for my bike. I’d like to record just how bad the cycling paths around me are and a high frequency accelerometer is really what I need.
Anybody else notice like halfway through when they show William the egg Allen pan in the background just nodding his head, waving it back-and-forth and smiling
Fascinating-this is the kind of physics lab that my dad would have loved to engage his classes in! Real problem solving with plenty of engineering and fundamental physics all bound together by math. I look forward to seeing what others choose to do with your eggsparament!
I would absolutely love a handful of these for my engineering courses. I have a digital electronics class that could make them and a design class that could do the drops.
Hey just wanted to say, I love this video. I’m currently in Germany (Bayerische) which is maybe why I got recommended this. Been a fan of William for a while, keep up the good work!
In the idaho potato world we use equipment called bruise balls to ditect the rough points during harvest. These eggs reminded me of these bruise balls. Look them up if your interested in seeing equipment that would have similar components as your digital egg.
That's pretty awesome. One of those would be pretty amazing to get a kiwi crate or similar educational box that's out there. I don't know what else could come in a box, but an eggdrop challenge box would be pretty great for learning.
As somebody who buys fertile eggs on eBay, this would be such a good idea to ship with the eggs to indicate if the shipping had any rough handling Instead of an SD card the MCU flash could just record the largest acceleration value and display it on screen Edit example: Int last_value; Int max_accel; Void loop(){ last_value = readAcceleration(pin); if(last_value > max_accel){ max_accel = last_value; } dislay.print(max_accel); }
If you ever want to try this again (which you totally should!) You could try 3 d printing the outlines instead of laser cutting them and spending all that effort to remove the color sections. You could print a single wall outline of the sections
That criteria doesn't matter if the person (egg) dies (breaks) on impact. Awesome video. You managed to fit a ton of stuff in such a small space.. Well done!
This is making me reminisce about doing the egg drop in science class. I agree that this electronic egg could be a perfect STEAM product, and a lot of fun to also decorate and give your own touch to do.
But protecting an egg isnt just about acceleration. It also can rely on soreading out the force, or physically holding the eggshell together by strengthening the shell.
What a terrific project and video! I remember doing egg drop challenges at Cub Scout camps more than 40 years ago. The most fun was always seeing the various strategies kids came up with, from packing the egg in a padded cardboard box to adding parachutes or propellers.
If you are thinking of doing a PCB, I would recommend switching to the ESP32. It has multiple MB of storage space built in, bluetooth/wifi built in, if you want to do a mobile app for it for downloading data, seeing live status or resetting it. And if you do PCBA with jlcpcb, it would be cheap to source and have the chip placed on the pcb in pcba. I think you will find a suitable accellerometer, and ws2812 leds in their stock too, so everything could be presoldered by jlcpcb, so you only need to attach battery and casing. And the jst plug for the battery can even be added in the pcba. so no soldering required if designed properly :)
I won the egg drop at school by shoving a bunch of crumpled up plastic bags into a large oatmeal container, with the egg right in the middle. There was a single bag on the outside to make sure the cylinder always landed rightside up. That thing could have survived a drop from space lol
That seemed nrf52840 is absolutely amazing and so full of power, I've been using one to build a GPS based laptimer due to just how damn fast it is thanks to having an FPU.
Really great engineering Stefan! Only thing I can think of that isn't egg-xactly like a real egg would be pressure. Eggs are very strong under even/all round compression. When I did egg drops in elementary school I actually just got a Tupperware container and packed it with as much cotton as I could on all sides very tightly to apply even pressure all around the egg, even the top, and just chucked it out the window with the standard 9.8m/s² - no parachute or other drag and no compression for dampening at the end and the egg was fine because of the even compression on all sides of the egg even though the impact was as bad as it could possibly be.
Here me out for egg 3.0 To transfer the data wirelessly. You "crack" the egg over a hard surface. The action of banging the egg and doing a pouring motion measured by the accelerometer begins the wireless transfer of the most recent data or all the data. Quick Edit: I know we've moved on from the archaic world of physical storage transfer and stuff. But cracking the egg open could also eject the SD card
That was fun. Egg drops was one of those "I finally got to the grade where we do this in some class" events (bridge with no fasteners is another one that came to mind) and it was always great to see what people did. I tried to make crumple zones, padding, etc. and got better as I went from grade school to high school. My favorite someone did was just paint the egg :P What better way to do things then to make a digital egg and calculate all the values for it. A ring buffer is a good choice and I wonder if streaming straight to a card would've been possible (I/O writes sometimes like bursts, other times stream, other times are random) to get more data out
the first time i did an egg drop challenge in school, i got some antistatic foam that my dad had collected from electronics packaging, filled an ~8x8in cardboard box with it, and carved a hole in the eggxact center that was just tight enough to gently squeeze the egg so it didn't move at all. It'd been my plan since the first time I ever heard about egg drop challenges. My teacher was so impressed he had the school's star baseball pitcher chuck it as hard as he could against the wall. The shell remained intact but when we cracked it afterwards the yolk had broken from the force of it, lol
I guarantee there are kids that would want that egg just as a pet. You could add a little program that if the egg is kept safe long enough it hatches and then there's a little chick live on the screen. And then the accelerometer data could be used to let you know if you're keeping the chicks safe until they grow into an adult
This is so cool. Such a great and surprisingly useful project. I've never participated myself, but ive often seen references to projects that revolve around "Egg Care", or whatever. Think about these scientific eggs being used in those parenting projects where students are tasked with taking care of an egg over the weekend. Again, very cool idea. Nice job!
oh yeah... T T i remember when i did it in hs. i had undiagnosed adhd- u can imagine what happened to the egg..... having an unspoilable "egg" would have been great
Hi Stefan could you make a video how to get the best abs results which kind of support is the best and how to provide layer separation. It would be so cool if cold make such a video 😊
The issue I see here is the sampling rate. It feels like the peak is only determined by a single data point, meaning the real peak could be way higher. So one room for progress would be to find an mcu with a higher sampling rate
It would be great if the egg's screen just output that final number without the need to download data on the spot. It would still need to record the data to an SD card to be retrieved later to show the exact force values. But in a school competition setting, they need a definitive number to set a winner of the competition. The reason why would be lessons in the days to follow.
I used a Xiao for my senior design project. They’re incredibly capable microcontrollers for the 10-20 that they cost. I was surprised to see it chosen for V2.
10:45 Hmmm, I think I'd just hover the 3d pen relatively high in the air and create a plastic nest by drooping the plastic in the air... might be time for an eggdrop challenge at home 🤔
This would actually be an eggcellent candidate for a custom PCB (sparkfun, or maybe PCBway)... voidstar might be a good collab. I would totally buy an integrated board with accelerometer, OLED, SD card, and neopixel indicator.
With Bluetooth you could put the data on a phone. If you're going to go the soldering route, you could use an esp32 s2 and flash chip instead of the seeduino, so everything is on one board, since you're dropping it no moving parts might be better
Hi can you do a test regarding how much pla and pla+ warps (on steep overhangs) depend on printing temperature durning in high speed printing? It seems like pla+ warps more when it’s not heated enough for whatever reason. This becomes very annoying when printing fast and frequently cause layer shifts. I think I will be cool to test it out to decrease the chance of a collision and layershift and help fine tune temperature and volumetric flow rate, speed and maybe nozzle size as well.
