Insane Tech for a Kids Toy!?!

- The Leapfrog 100 words book is a neat piece of durable technology which could help children's hospitals around the world if the menus were changed a little.

After a good night of sleep and seen a partial repair/teardown video of such a LeapFrog learning book, it seems very simple how this works.
On the inside of the blue part (Pets page), and topside of the bottompart (Opposites page) are 8 capacitive switches, so 16 capacitive switches in total.
For the microcontroller to know which of the 16 capacitive switches is pressed, it use the combination of the position of one of the 16 capacitive switches and the "page switch" which is choosen by the colored rings. With the 6 colored rings , a set of 16 values per page is added. Opening the book unpress a microswitch by turning the blue panel, which had a plastic notch on the bottom that press on the microswitch when closed. So 6 times 16 gives 96 different values. With the slider switch on the sidepanel, you can make a extra set of 3 times the 96 values, that change the outcome of the 96 different values.
Father of 2 year old twins and mechanic shop owner here. this video you made inspires me to not only buy a few of these toys for my kids, including myself so we can all learn something. I don’t post many videos but I might just to answer some of your questions maybe. Anyway, got a new subscriber here and I look forward to watching more of your videos. I just got to know too. That’s amazing!
A theremin controls amplitude and frequency with two antenna which heterodyne based on hand positions. Maybe the book senses proximity using the hand position relative to the x and y axes near the page
I'd try destructive next yeah, very very cool. Tried looking around specific leapfrog patented for bout 15 minutes can't find anything specifically related. Tickles my brain too lol, thanks for the share.
A variable piezo circuit? A motion or light sensor?
Try this : bent a page a little bit up, but make sure that the colored ring of that page stays down. Then try if you get reaction when touching a symbol on the page.
If you don't get a reaction, then i think it works like this : each symbol generate a value, but with multiple pages on each other, these values add up.
It seems that all the symbols are on the exact same spot on each page. So i guess that there is a sensor on that place in the hard outer pages. Then this sensor "reads" the amount of symbols that are stacked on each other on top of that sensor. So per example, if the symbol on the right bottom place has a value of 1, then this gives value 1 with only 1 page down, and with each extra page on top, the value grows with 1 per page, so 2 pages give a value of 2, 3 pages give a value 3 and so on. Then the symbol next to it has per example a value of 2, so 1 page gives 2, 2 pages gives 4 etc...
If the the symbol next to it has a value of 2, then 2 pages on top give a value of 4 on that exact spot.
See it as piles of coins of different values in rows and lines.
I tried the bending trick - doesn't register the touch
@@BetterBiomedChannel , could be sort of proximity sensors in the outer shells, and with only 1 page or multiple pages stacked, the signal strength changes. I think a teardown of the outer shell (part where the batteries are stored) would reveal the secret sauce :-)
Probably a capacitive sensor.
That is certainly some impressive tech I've never given any thought about the kind of tech people put in these things! but I agree with your assumption that it might be an infrared sensor. I'm thinking it's possible that the light intensity gets stronger depending on what page it's on. I especially think that is the case because like you showed the pages are semi translucent. If it was capacitive they shouldn't have any need to make it translucent like that. One would also expect to see some kind of wire within the page for a capacitive solution. Another thought I had was maybe its some kind of RFID but why have that if the pages need those index switches.
Eitherway definitely a thought provoking little piece of tech! I'm curious to see what the answer is too. Given how it's semi translucent you could try shining a flashlight on one of the activation areas and maybe that will help show whats under the hood.
The only thing I can liken it to would be a ultrasonic depth sensor light on a drone with some specific frequency that the paper Pages cannot interfere with
@@danielmcgee813 Thats true. Could be something like a stud finder now that you mention it.
