Help simplifying an Arduino Nano setup for kids' electronics workshops (wiring and battery power)

I'm developing hands-on STEAM/maker workshops for children where they design and build interactive creations using an Arduino Nano, servos, ultrasonic sensors, arcade buttons and WS2812B LED strips.

The idea is for children to connect the components themselves (with adult guidance), so I need something simple, reliable, safe and independently powered so they can take their creations home.

I paid a PCB designer to develop a custom Nano carrier board with JST-XH connectors, an ON/OFF switch and external power input.

I'm currently facing two problems:

  1. Power: The board works when I connect a USB power bank directly to the Nano, but powering through the PCB's external JST-PH input hasn't worked reliably using a 4×AA battery holder. I've also tried a USB-C power bank connection, with intermittent results. The power LED sometimes flickers when I touch the board's switch.
  2. Wiring: I'm currently using JST-XH-to-female-Dupont cables, followed by male-to-male jumper wires to connect components such as servos. It's messy and not ideal for children assembling their own projects.

I'm wondering whether I should try to salvage the custom PCBs or return to a standard Nano expansion shield, which has worked reliably in my tests.

What would you recommend for simplifying the connections and providing safe, reliable battery power? Is powering the Nano directly via USB suitable when running a servo, ultrasonic sensor and LEDs together, or should I be using a different power arrangement?

I'd really appreciate advice from anyone who's built similar educational electronics kits!

Is this custom Pcb and can I get one made?

So my kid did a workshop and I have some questions…I would like to replicate this to make my own.
Is the image a custom pcb? It’s a maker workshop for kids so I assume this way it’s easier to connect cleaner wires?

My kid chose a motion sensor, lights and movement as his interactive elements but you could also chose sound so I am guessing it has connections for those.

Could I get a similar board made cheaply?

I would like to do this with my students too so want to learn myself.
Thanks

Stumped as to how this is done...

I have experience with microbit and I want to learn arduino - I want to learn by trying to copy projects and Ive seen this one. But I don't know what resources they are using? What board, battery pack, etc...

Can someone help me identify?

Ive bought a nano board and some servos etc but first hurdle is the battery pack I bought has red and black stripped wires so no way of connecting anything :(

Im going to buy a starter pack next, which hopefully comes with what I need to try things...

But anyway, if anyone knows what is in the images please let me know!

Forerunner cycle? Buy end of August September or wait?

So I’ve got a 945 and have been wanting a new watch for a while. The wife is into running and wants to try her hand at triathlons - she doesn’t however want an expensive watch so we were thinking I buy the 970 and she can keep my 945…..maybe even buy the Cirqa and only wear the 945 for running, cycling and swimming.

But my question I guess is, I will probably only buy the 970 in end of August perhaps September….is the newer version likely to come out then? Should I still get it or wait to see if a new version appears?

Finally a little bit off track - I’m not a watch wearer, the first watch I wore was the 945 - should I stick with 979 style or try fénix 7 or 8?

Help from a newbie - looking for simple low cost option

Basically I want to run some workshops where kids build a cardboard robot that has one moving part (maybe 2 later on). There are many examples of this online. Using a servo motor a part will either spin 360, or move left to right etc.
I have done this with a microbit, however never with an arduino. I am looking to run this workshops with at least 10 kids and trying to think of the logistics of them finally taking the cardboard animal/robot home including the board etc so needs to be cost effective.

Is this possible with an arduino? What parts would I need? Arduino nano? a power source like a battery pack and then of course the servo?
Can you help me understand what parts I would need and also if there is a kid friendly coding interface like with the microbit using block programming?

Thank you and I appreciate any help you can offer for a newbie!

Renew Car tax - Bangkok

Hi,

My car is due car tax registration and I need to renew. Ive had it for a year and need to renew. I can't seem to do it online as it asks me to register and asks for my Thai ID. How can I renew my car tax registration?

What to get after a 945?

I’ve had and loved my 945 - battery in my opinion doesn’t last as long anymore and I’ve had it for years and years.
I haven’t used all the features but loved having them. Now I am thinking of upgrading to a newer model and initially I thought of I’m going to cough up the money for the 970 but then I saw the 570 and thought hey that looks like a nice cheaper alternative.

I don’t really use maps but the one time I had to it was nice. I use wikilocs to load trails on it or at least I did one summer and I thought that’s cool - not sure if I should save and do the 570 or wait and get the 970.
I want to be healthier as I age.

970 - 570 - what is best fit

I have a 945 that I love but realistically I don’t use most features - I love it and love features but I am now thinking that when I upgrade perhaps the 570 is a better fit. And cheaper.
I run mostly - but with age, already at 41 I want to do pre swimming and other activities - I’m doing a triathlon soon for the fun and because it’s always been a dream.
So, is the 570 a cheaper and better fit without giving up too many features?

Discounted 165 for my wife?

Delano’s only today - in Thailand it’s discounted to about 150usd in local currency.
Is it good for my wife? Runs swims and is trying a triathlon but don’t think she needs the triathlon feature as it may be a one off.

Thoughts?

For myself in considering the 970 from a 945

My wife made a paper collage with kids work stuck on large canvas - help seal it [ANALOG]

Kids work on paper lots of different materials - pencil markers acrylic paint all on paper and cut and stuck on a canvas.

How do we seal it without ruining the work - smudges bleeding etc?

How do we flatten the piences and then how do we seal so it’s protected?

Thank you!

Sealing a collage - kids work and my wife’s the artist!

My wife’s a teacher but she is also an artist! She’s made a big canvas and created a collage using all our kids work they bring in from school. So paper made by kids using different materials all cut and stuck on a big canvas.

How do we seal it and protect it for a nice professional finish?

I want to learn how to design simple pop out designs like the attached images. I am not a complete novice. I am looking for help or links to courses or tutorials.
I am particularly interested in workflows - how do you start and what tools etc to achieve this.
I can't draw but used AI to generate outlines and ideas. How can I leverage that and then make sure things fit sizing wise etc.
The SANTA one is one I bought on Etsy. I want to learn how to make items like that, simple but of different things. I would appreciate any help. Thank you!

So it was in its case and in my boot - my sons water bottle leaked and it’s been in there all day. Got it out and felt the case was humid shit!
Pulled it out and a few drops visible on the screen - wiped it down with a towel and took the joy cons off wiped everything - and on a table air drying - how long should I leave before testing?
I am hoping it’s only some water getting through the case but who knows!

Just received an email saying our claim is still being processed and to be patient and wait! How much longer should we wait before emailing again??

We travelled back to Europe from Asia just for one week because we had a wedding - of course we did not make the second flight as we missed the rebooked flight (impossible to make) they rebooked us again and we missed that one which involved a train of over 4 hours (delayed and cut at wrong station) to Frankfurt so we missed that rebooking too and then they put us up in a hotel and a flight the following day. Well over 24hrs late and we missed the wedding.

My understanding is they need to pay 600 eur per passenger so 4 - 2 adults and 2 kids.

Why are they taking so long and how much time should I give them before emailing again.

Not happy!
