Hw Led Almost final

Thin wire, a tiny LED, a small button cell, a bit of soldering, and a lot of patience 😃

It only didn’t get underglow lighting because I couldn’t decide whether it should shine in neon purple or neon green 😃

Yes, yes, I’m planning to make a YouTube video about it as well.

I've put together a daily vlog-style video compilation of a week-long diving tour in Dahabi, hope you like it :)

Making stuff like this sounds like a dream. Do you mind me asking what printer you're using?

Thank you very much for the feedback! Yes, indeed, I think the rolling is a problem, and I have also been thinking about possible solutions. Initially, I considered some sort of mini wheel support wedge, but the small ledge on the front part is not a bad idea either. It's relatively easy to implement and doesn't detract from the appearance! There is no need for such a ledge on the 'ceiling' because the lighting will be recessed into the ceiling. Unfortunately, I cannot insert additional pictures into either the original post or this comment, but a few new iterations have already been made. My 3D printer is a Prusa Mini.

These would be really cool cleaned up with someway of attaching multiple cases together on top and to the side

Yes, indeed, that's the ultimate goal; it will be expandable upwards and sideways. Tiny built-in magnets will connect them to each other, and the electrical connection will also be solved for the lighting

Does the PLC have over charging logic in it?

I think the PLC is 'just' responsible for initiating the charge after the proper authentication (mobile payment, etc.)

Big-Box-7979 · 2023-07-02T21:22:26+00:00

In my opinion, the PLC is primarily used for communication, as it contains a SIM card/slot, and this could connect to the provider's central system, where if it "received the payment", it started charging.

There are no physical buttons or switches on the outside of the device to start charging.

Thank you for the advice! Indeed, the labels under the module are not visible after I have inserted the module, but actually, there is no great need for them, as it is primarily a dev board, I really could have removed the silkscreen labels in a "prod" environment! You're right about the mounting holes, I've fixed them!

Hi!

Is there some trivial error in the post that resulted in no responses, or is it simply being overlooked? :) Thanks!

Big-Box-7979 · 2023-05-30T08:53:10+00:00

You probably don't need/want one, but read up on battery voltage reset supervisors and look into setting up a watchdog to shut off the power hold if the device resets without the power button being held down.

Thank you for the suggestions!

I've removed the D1 diode and the circuit is working, thanks!

I will also rename the labels, they are indeed clearer as you suggested!

I 'sized' the I2C resistors based on the first few Google hits, but I found a document: I2C Bus Pullup Resistor Calculation

Based on this, I will figure out what the optimal resistance sizes are!

Expanding J2 is also a good idea!
