Navadeep•1/14/24, 8:51 AM

is this with the same code?
after what changes did this appear?
did you try tapping the RFID card on the reader?

K.L.NAGARAJUOP•1/14/24, 8:53 AM

I had modified the code, I mean I changed the SDA and RST PINs allocation

K.L.NAGARAJUOP•1/14/24, 9:40 AM

Yes I did!

Navadeep•1/14/24, 9:42 AM

Please note which pin in NodeMCU is SS. It should either be 15 or 11 based on which SPI instance you call on your code.

Navadeep•1/14/24, 9:44 AM

Try SS pin as 11 for the SPI you're using.

In the serial monitor, pick 'NL and CR' mode from the selection below. This will get those junk characters out.

Navadeep•1/14/24, 10:17 AM

Okay. True, that makes sense. Taking this over a thread now.

Navadeep•1/14/24, 10:18 AM

@Phoenix do we have a way to move these conversations to a thread now?

Congrats!

The server is happy to support the production of additional prototypes. Are you willing to make as many as people who want one, Kristof?

@Phoenix, target thread channel ID not being identified (1196129943084613753). Need assistance moving images. After resolved I can migrate the rest of the conversation.

kristof-at-embeetle•1/15/24, 11:14 AM

I can put the DevHeads logo on the board, along with an URL

kristof-at-embeetle•1/15/24, 11:14 AM

Which URL should I put there?

techielew•1/15/24, 1:59 PM

you can put either https://discord.gg/DevHeads or https://devheads.io

Hey @everyone!
If you haven’t yet, follow our LinkedIn page! We’re pushing to get to 150 followers so we can set up our stream and share departments like Office Hours with the rest of the world

we’re at 122 right now!

Feel free to share with your connections, too!

kristof-at-embeetle•1/15/24, 8:30 PM

Hi guys,
Please have a look at the Tiny Scarab board design:

https://github.com/Embeetle/tiny-scarab/tree/main

I've wrapped up the board design and I'm now looking into the fabrication process. Eurocircuits is an option, but it's rather expensive. Please feel free to share your experiences with other board fabs.

As for the production files, please scroll down on the main GitHub README page:

JeremyCook•1/15/24, 9:51 PM

"There's no need to wire up anything. Just plug the Tiny Scarab in your computer and start coding!"

I suppose my question would be is it a dev board a la Arduino Uno, or is it a sort of GPIO pass-through that you control via your computer? Or is it something else? Maybe a TL:DR summary of what is it exactly? Nice looking board though, as are the docs aesthetics-wise.

kristof-at-embeetle•1/15/24, 9:56 PM

Hi @JeremyCook ,
It's a development board for the microcontroller. That means you can write code in any IDE and flash it to the chip (although we hope you will use Embeetle IDE).

The board has an on-board flash/debug probe which you connect to the computer with a USB-C cable.

I'll rewrite that part in the documentation to make this clearer

techielew•1/16/24, 6:41 AM

This is very easy to read. Thanks!

My first question is what does this mean:

“The Beetle Boards will get special attention in Embeetle IDE.”

techielew•1/16/24, 6:49 AM

My next comment is that @Petr Dvořák and @pallavaggarwal may have a decent handle on board gave depending where you’re looking to have it manufactured.

@pallavaggarwal, @Umesh Lokhande, what did Altium do to the Gumstix brand? Is there still a low volume quick manufacturing option through them in the west?

techielew•1/16/24, 6:50 AM

What is the cost at Eurocircuits? Have you considered a kickstarter?

Petr Dvořák•1/16/24, 6:56 AM

@techielew Because of the Chinese chips, I would consider JLCPCB or similar companies. Everything else probably brings more headaches and higher cost.

Petr Dvořák•1/16/24, 6:57 AM

Another plus is that JLCPCB offers 3D printing and CNC machining. @kmulier can design an enclosure or some kind of accessories easy to order there.

Padmalaya Rawal•1/16/24, 10:15 AM

I would love to contribute @techielew .

@kmulier As your board is open source, you can apply for OSHWA certification which is free. And then you can ask people at OSH Park for your initial PCB fabrication. And if you are considering to produce them in bulk I think it will be better option to ask JLC or PCBWay for the sponsorship. They will reduce their prices in the exchange of their name to be there on prmotional material and github. I hope it helps

kristof-at-embeetle•1/16/24, 12:35 PM

Thank you guys.

Yes, Alibaba is now the only distributor for WCH outside China.

Thanks for the tips. So right now, the options for a prototype production are:

Eurocircuits (800 euro for 10 pieces, this includes assembly)
JLC
PCBWay
OSH

@kmulier Be aware, those sponsorships can backfire easily.
