He loves to disassemble things. His mom asked if I thought it would be ok to get an old vcr or something from Goodwill (snip the cord for safety) so he can just take things apart.
I was wondering if anyone here had a rec for a toy, or if old electronics like this are dangerous. Any and all thoughts welcome.
I'm not sure how mature he is, but here are my guesses. He may need to grow into some of these:
Golden books (in electronic format on a tablet)
Lego Mindstorms - get plenty of spare parts Get him on a First Lego League team
RC Car (that he can assemble and modify) - get plenty of spare parts
Estes Model Rockets
Slot Cars are still around - get plenty of spare parts
Computer Programming with Scratch or MIT App Inventor
Talk to ChatGPT
Arduino-based or Raspberry-Pi-Based robot - get plenty of spare parts
I recently enjoyed taking apart and modifying pens from Dollar Tree. I took a bunch that I liked the look of in various colors, but that all had black inks. I changed out the inks for inks from inks in vibrant colors that I did not like the look of.
Cutting fretwork on a scroll saw - scroll saw and drill press required.
If he's too young for any of this, try showing him how to do it. Be patient and show him 3 or 4 times before giving up on one hobby / special interest.
Edit: Looks like they're still alive and kicking! https://basicfun.com/knex/
Lego technics are excellent. I remember Zoids being neat too. For taking stuff apart, I think things with motors work well, e.g. blenders or old drills (metal casing ones best).
My youngest (5) was able to put together a plug-n-play kit and was extremely happy with the result, though he has crashed it to death since and I'm waiting on replacement parts.
I can't find the one we went with, but this is similar: https://ca.robotshop.com/products/airbit-2-programmable-dron...
This one is arguably under-featured and over-priced, but gets the idea across!
Also echo another comment that some electronics are more dangerous to disassemble than others. For example cameras with flashes can have capacitors that hold a charge for a long time.
An old VCR is safe enough. He might cut a finger on a sharp edge but that's ok. Sounds like he's already curious, so let him have at whatever you can scrouge from a junk sale for $5. Cheapest education he'll ever get.
Some other ideas that cost next to nothing and let him explore the open world we live in:
USB Microscope - he'll be able to see the mechanics of texture in silk vs cotton and salt vs sugar vs flour, as well as the 100s of creatures in a drop of puddle water.
Infrared thermometer - highly useful and informative from now into adulthood. "Hey mom the oven temperature is wrong, it says 400 but my thermometer says 380," and "Little sister has a fever, it's 100.5 inside her ear," and "it's 935 degrees in the fireplace, and the windowsill is 41." Wholesome stuff.
A kitchen scale. High quality magnets. Samples of different materials. One of those green plastic sheets that make magnetic field lines visible.
And real tools - whatever he's ready for. In my generation, boys got their first pocketknife at age 6-8. I'm sure he'd appreciate a quality multitool.
If you love the kid, the next time you have to fix something like a lawnmower or a car, do it at his house and both of you will have a fun afternoon in the garage. Bring lemonade to keep the bloodsugar up. He will remember that day fondly for the rest of his life.
tl;dr: skip the toys. show him the real shit.
The pinnacle, before they got too realistic body work was lego test car 8865. Once built its robust enough to play with. The engine is a little tricky and the gearbox might be puzzling to an 8 year old but its a great set for learning how a car works without being aimed completely at the grown ups market

Around that age I was given a motorcycle battery and a variety of bulbs, relays and car parts. Unfortunately these days, electronics and miniaturization has reduced the scope of what can be educationally taken apart.
To avoid recommendations I've already seen, I'll recommend balsa wood planes, a paper airplane kit, and perhaps some kind of kit to build a propeller-powered item. I forget what these are called. Whirlygig?
This is the kind of thing you can make projects with just with cardboard and various fastening elements, in fact - tape and rubber bands and glue. It's not necessarily about "real electronics" at this stage, it's just that electronic objects have a combination of intricate design and visible access. Art often crosses over with this stuff in that you can also "take apart" things by transferring their visual appearance into hand motions through blind contour drawing. Graph paper and a color multipen can be a huge hit for this kind of kid, if they're shown how to use it to this end.
Admittedly 8yo is a little young to start. There are challenges, and patience is a must. But the family can find a local makerspace (or library, or school) to get a better idea of what's involved.
Great blend of mechanics and software.
Side point, if they like this check if there are robo Lego leauges in you area. Great extracurricular activity for kids.
Do the hard work upfront to find something compatible, in particular around batteries (so they don't e.g. start a fire). From there, upgrading a regular bike to an e-bike and routing all the cables / logic circuits / etc. is a project unto itself. At the end this kid gets a fun and efficient means of transportation, as well as the satisfaction of knowing how their bike is put together both mechanically and electronically.
