I asked to some friends if they have great project idea that could be done by an 8th grade kid with or without support. I personally like to do it with him as it is a privileged time to build something together (for me) and learn new skills (for him).
The purpose of this thread is to assemble some ideas for Christmas presents.
I’m starting…
1. DIY LED Christmas tree kit for soldering (https://www.az-delivery.de/en/products/diy-weihnachtsbaum-kit-alles-inklusive-versandkostenfrei)
2. Software Defined Radios kit (https://www.rtl-sdr.com/about-rtl-sdr/ and https://www.amazon.com/dp/B0CD7558GT)
3. DIY Internet Radio Alarm clock with touch screen control (https://www.az-delivery.de/en/products/radiowecker-mit-dem-az-touch)
Any other ideas or suggestions?
Also, I like to reinforce the concept of “dreaming it up”, tell my kids to think of a thing to make and we break down the steps we think are needed to build it. At first, it’s like their imagination wasn’t big enough. They’d have an idea and I’d show them how we could build it pretty easily. Now, it’s gotten to where they know the skies the limit and anything of kind of possible so they start big and then work their way back down to a realistic scope of features. All to say, ask your kid what they want to build!

You could build a sonar system, listen to ultrasound, or almost anything you can imagine, thanks to Moore's law and the massive amount of compute we have these days.
It’s free and nonprofit. There are 60 locations. Maybe one is near you?
A lot of old school maker projects are fun, but they're also basically E waste making kits now that phones do almost everything.
Not having a bunch of low tech gadgets laying around is really nice, they can easily become the biggest clutter challenge in a space, the same way paper used to back when more people still used it for things other than books.
Building a small solar energy system is fun and easy, and also practical.
3D printing is fantastic.
Meshtastic has a lot of DIY and learning potential and is like the lite edition of ham radio. What's really cool is that range testing gets you outside.
Maybe design something together with JLCPCB and have it made(Leave off any through hole connectors and solder them yourself for both fun and pretty decent cost savings).
Lego?
Unfortunately, my limited (geographically-constrained) contact with my nieces and nephews has severely impacted my ability to influence them towards technology. :(
Exposure is one thing that is helpful, but in the end, you have to find something that your son is so enthralled with that he wants to pursue it on his own. It begins with curiosity about something, of course, but ultimately requires him to develop the skills and then the confidence to where he wants to begin doing things on his own.
The problem is in the things that parents subject their children to that actually drive the children away from those things... like piano lessons! (I say this as a pianist that has taught many children over the years, and it's obvious which kids are being forced.)
What does he like to do?
For each hour they "make", they earn "Doubloons" which they can spend on things they need for more projects - like soldering irons, Raspberry Pis, Framework Laptops, and more.
There are about 900 teenagers coding each day and working on different projects. He might be inspired by some of the things they're working on, like this personality quiz (https://personalityquiz.kittycat.hackclub.app/) and this overly aggressive cat-themed study timer (https://study.sticks.gay/).
One good beginner activity could be making his own homepage, which he'll earn a boba tea for: https://boba.hackclub.com
Building a fender-style guitar first is the easiest route, especially if you use a double-truss neck rod (get it from Stewart Mac). I recommend buying a pre-cut fret board as well. Also, you can use tung oil instead of clear coating. Trying to do an opaque spray job was my biggest regret. I could have oiled my beautiful mahogany body with much better results.
Tools:
* Flexible edge (for pegboard and body profile https://shop.pacificarc.us/products/flexible-edge-curves)
* Bandsaw (body and neck shape)
* Drill Press
* Router (For the neck and body cavities)
* Thickness planer (only need this once to plane the body wood before gluing)
* Curved carving knife (Like this https://ramelson.com/product/curved-hook-carving-knife/) to profile the neck.
* Pipe clamps
Nice to have tools:
* Oscillating spindle sander
* Belt sander
* Router table
I recommend using an easy to work wood like maple for the first attempt. I found mahogany to be a lot of effort to work. Expect the project to take quite a wile. I think mine took 200 hours.
I think sort of "choose your own adventure" projects like that are great, and they also force you to really understand everything you're doing. You can also scale the scope of the "project" to whatever you want; it can even be a sort of iterative process. More importantly (imo) you're left with a bunch of components that he can tinker around with endlessly :)
I believe SparkFun has a similar ecosystem of products and projects as well.
I'm not affiliated with either of these companies.
- 3d print a stand (here's one I did https://github.com/SalvatoreT/howmm/blob/master/week06/Traff...)
- incorporate an infrared sensor + infrared light to simulate triggering the red -> green flow
- make an intersection with each of the lights working together to show the right thing at the right time
- add a crosswalk
You know these 'sticks' that you hold an ice cream with?
Bend those into a propeller. Wet them with water if they crack. Drill a hole (or cut with knife) through the middle and put it on a small electric motor and attach a battery or power source. Spin it up and watch the propeller fly off.
Just give him or her the things and say the goal. And that you don't know if it will work. The hard part is figuring out to bend with water and to get the right fit on the hole to the axis.
Fun, quick project. With my kid, I healed the iron and they held the solder. I’m guess a 13 year old could do more (or all) themselves.
Then there are options for tweaking the program, like different patterns, a “count down” to Christmas, etc.
Here's my method: https://jsnow.bootlegether.net/cbg/cbg.html
Like, I was making games in Visual Basic. Made a little Tyrian clone. It had total of two levels :D
The key is to spark something that creates an obsession IMO.
For the drone I just bought the parts over time and one day he asked if he could put it all to put it all together. It was a bit of a bitch debugging his mistakes but I’m glad he took an interest and applied himself

This is a great way to get Linux experience. One student used these skills to work on Medtronic GI Genius via YOLO AI.
You can get a mirror set very cheap on ali, eg https://www.aliexpress.com/item/1005005098614936.html
You'll need to buy an eyepiece or two, and hardware, bolts, etc, but everything else can be made or 3d printed.
I designed and made, with my kids, a 76mm 'cheapscope' using PVC pipe, 3d-printed mirror-holder, spider. focuser and camera-tripod connector, here: https://imgur.com/a/cheapscope-4KtPgoN
I meant to post the 3d-print designs but haven't got to it, let me know if you're interested.
For sure it's not the best scope (or design) ever (and the 3d prints warped a bit), and no phone/camera eyepiece mount so the pictures are shaky, but it works, it was fun, and opens up a new world(s).
I can think of a million things, but ask him what he's interested in doing.
1. Carpentry project
2. CNC machining project
3. Microelectronics: assembly from ready parts
4. Drone or aviation related project
if he is into computer stuff, just teach him how to hack computers and websites, the pentesting stuff.
8th graders need to make noise.
Good luck.
