Hi Tildes,

I'm looking to introduce my children (aged 10 or so) to simple electronics (blinking lights, simple sensors, ...). I've played with Arduino in the past, but I see that there are now many competing options: Arduino, cheap rip-offs, RPi zero, adafruit, ESP32, ... It's easy to get lost!

Which do you recommend? Ideally, I'd like something cross-platform and open-source, easy to set up (ideally a kit with everything included), and of course not insanely expensive.

Edit: thanks everyone for the good advice! There are so many good options...

I recently went into my attic and pulled out my old 1990s 4-track Fostex X-26 tape recorder. I was hoping to transfer some of my old band tapes to the computer. Alas, it is dead. While it turns on, the motor appears frozen, and the device hums. (I don't mean there's line noise when you plug a speaker into it, I mean the device itself audibly hums, even when not using the tape controls.)

I have seen online that some people repair theirs. It's probably beyond my skill level to do so, though. (And I don't really want to do it myself.) I have contacted a few shops near me (Los Angeles), but have gotten no replies, unfortunately. I was wondering if anyone here knows of a good shop that would repair an older device like this.

I have also contacted some places that claim to do cassette to digital transfers, but none have replied to my questions about whether they can deal with a 4-track recording. Also, just looking at their prices, it seems like it would cost significantly more to have them convert my tapes than to get the recorder repaired. (And I'm not sure what's on all of the tapes, so I don't really want to hand over some embarrassing practice tape or tape containing some out-of-context banter between takes on it.)

I've looked online for a used one, but all the listings I've found have been "for parts only", which is what mine would be if I were to sell it. And knowing how these things go, they probably all have the same broken part. So any recommendations are appreciated!

Back when I was a kid, I had a radioshack 200-in-1 science fair electronics kit this one

I loved that thing, and it sparked an interest in tech that ultimately led me to a CS degree.

Id like to buy something similar for my much younger sister, but nowdays everything I can find is arduino or raspi based. Id love to get something like that eventually, but I think it might be better to get a kit that more focuses on individual components first... Does anyone know of one sold these days?

Alternatively, if anyone has one of these and would be willing to scan the book, Id love to build one of these as a breadboard-based system.

I’ve been wanting to get in to hobby electronics now that I have some free time, but I’m not sure what I want to start with. I am super interested in building an 8-bit computer but I’m curious what other types of things people have built or are building. Feel free to talk about any Raspberry Pi or Arduino projects as well even if they’re not strictly ‘hobby electronics’.

I recently came across a cool video on youtube. https://www.youtube.com/watch?v=dxj8JwdQ7Lk&feature=youtu.be - The guy added a 4g connector to his rc plane and I think some extra batteries and managed to fly to the next island over.

I love stuff like this. Do you guys know any other current electronics that can be modded like this? Sadly it seems like most new consumer electronics come with their own small walled garden and often enough stuff just stops working once the seller goes bankrupt.

Other things that come to mind are:
Raspberry Pi
Arduino
ESP
But do you guys know whole systems that are moddable like this?
The Ryze Tello is a programmable drone, which is pretty cool as well.
I also saw some people modding 3d printers to laser cutters

Let's do a little show and tell for our new toys :)

(I was thinking about this as a non-recurring equivalent to the listening threads and such but I probably worded it a bit too...fluffily for ~tech so I moved it to ~talk)
