content: Quote from: strawberry on October 23, 2022, 05:41:44 pmNo, not silly at all, but it has to be better/different than the 38767 other existing fast prototyping/learning kits, that ranges from 8051 and 6802 to the latest multicore MCUs, with an enormous assortment of interfaces, "hats", displays and touch panels.Cheers,DC1MC

content: was thinking about basic stuff first . OP amps, resistors ...Could be didital circuits as well, including MCUs32768 ?

content: Some per-existing stuff:https://download.mikroe.com/documents/specials/educational/aslk-pro/aslk-pro-manual-v103.pdfhttps://www.digikey.com/en/resources/edu/harvard-lab-kithttps://www.analog.com/en/education/courses-and-tutorials/active-learning-module.htmlhttps://de.rs-online.com/web/p/analoge-entwicklungstools/8904008https://university.ti.com/en/faculty/teaching-materials-and-classroom-resources/ti-based-teaching-kits-for-analog-and-power-designhttps://theelectronics.shop/product/edubit-learning-project-kit-for-microbit/plus the rest until 30K, now with more Arduino, RPi and NucleoAs I've said, the idea has to be REALLY original and affordable to compete with the existing offers. Also no youngster that I know of wants to touch anything related to electronics, all they want is to do some killer app, magic SaaS, next Twitter or something to get rich like their idol Zucky, they say that whatever actual stuff they'll design will be copied and sold by Chinese in no time. can't really fault them, this is exactly what it happens.Cheers,DC1MC

content: Yes this idea is as old as electronics.Here is two picture searches of what I learned my way into electronics with. There are many others like these from the old days.https://www.google.com/search?q=philips+electronics+experiments&tbm=isch&ved=2ahUKEwjeo8r0h_f6AhXCaqQEHQIwBK0Q2-cCegQIABAA&oq=philips+electronics+experiments&gs_lcp=CgNpbWcQAzoECCMQJ1CbD1iBE2DZG2gAcAB4AIABQ4gB5QGSAQE0mAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=wZJVY56_JMLVkdUPguCQ6Ao&client=ubuntuhttps://www.google.com/search?q=fishertechnik+electronics+experiments&tbm=isch&ved=2ahUKEwjz146FiPf6AhW1nCcCHUrkDt4Q2-cCegQIABAA&oq=fishertechnik+electronics+experiments&gs_lcp=CgNpbWcQAzoECCMQJ1DVCliKJGDWNWgAcAB4AIABbIgB8gaSAQQxMy4xmAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=5JJVY_PVELW5nsEPysi78A0&client=ubuntuDon't think there is much money to be made unless you come up with a really novel new approach to it.

content: not a toy , not like TI proto reduce soldering effort and messy wire clutters found on breadboardsmaybe useful as arduinosome are fighting back china copy on amazon

content: Quote from: strawberry on October 23, 2022, 05:41:44 pmNot at all. Even the biggest development projects go a similar route. On the bigger projects, its very common to have several tables full of test boards all wired together demonstrating the system fully running knowing it will eventually be condensed down to one final board design. It not only allows the software developers to work in parallel, but also helps better refine the hardware design.Also, in general, software takes longer to develop than hardware, and many times you change the hardware design as you know more of what your wanting to build. My suggestion is to start with some mikroe click boards (Adafruit and SparkFun make great boards too but have a much more limited catalog) to give yourself time to write your software, talk to the intended end user, and further refine the idea.After you know what you want and have fully flushed out the project idea, making the final hardware is actually the easy part.

content: Years ago, before all this electronics boom, I thought on making a board full of pci connectors, all pins connected together in a bus, then making a master card (CPU, Pic, avr, whatever) and a bunch of prototyping PCBs where you would solder all kind of stuff, having all signals available there to use, avoiding lengthy messy wires everywhere and allowing quick removal or addition you would insert any card in any slot indifferently.The idea was to avoid the usual problems in breadboards and to easily add and removed modules.Well, just like today with Arduino hats, but better.However back then PCBs were no close as cheap as now and didn't pass the idea stage.

content: Here is also an Amplifier PCB that may interest you.https://www.pcbway.com/project/shareproject/LM386_AMPLIFIER_PCB.htmlThis is based on LM386 OPAMP. If you see the datasheet of this OPAMP, you'll find more designs with different gains.

content: The idea is attractive (for enthusiasts only), but I doubt it would be profitable. Try it, but don't bet too much in advance.
