Everything we didn’t want BUT it is dual-freq : )
It also has some cool other features but there might be some deeper issues. We’re waiting on something to test deeper.

With pcb design the way it is nowadays… couldn’t we just build our own variant of this that isn’t fucked?

Sure. We’re just busy with so much other stuff : /
But the community is amazing and you all have put together some awesome projects. Some of which have ended up as products.

And that’s fair…
I’d volunteer, but I can barely keep my electrical theory straight haha
I just wonder if it’s possible to do the pcb way, send them a schematic and they assemble thing…
But I have no sense of what level of design this entails… I’ve seen some people spit out cool
Things like it’s nothing… and other stuff is a struggle bud

A lot of the problems are in software, unfortunately. You just can’t be anything less than hypervigilant with C and it’s the mainstay of embedded programming.

Morning. I will be revisiting my simple access controller project after finishing my lock. Im sure togeather we could all bust out something cheap n reliable for under 10 bux. - with optional audio

Ill be starting the preliminary discusions on this build shortly. What do you want it to do. /not to do. Hf or lf? Manual uid entry or slave master card method of uid entry. Relay Flipflop or on/time/off. Onboard Beeper? Premade or diy kit. Write as detailed as you can as i will be showing the team this post.

I think the xACv2 overall works pretty nicely, it’s just a shame the security flaw, so proper checking if bits and no silly flaws
it would be nice to have a hf variant
It would be nice to have a flip flop mode
Would be nice to have 2 antenna inputs using jst plugs… if you wanna do something on either side of a door or something
Probably dreaming to suggest it, but the ability to add in a “stop switch”, If you want it to power a motor when tag presented… but it needs to stop at a specific point
I know people can do arduino things, but that’s always been a bit beyond me… the xAC was simple enough for me to do stuff caveman style and get away with it
… a built in magnet into the design could be nice

Sorry, what would be the purpose of the magnet?
Does it need a purpose? It’s a magnet! But yeah, what’s the purpose?.

Agreed on most of this - really just a dual frequency controller without any major flaws would be nice.
EDIT - looks like there are off the shelf solutions today from Honeywell and Paxton, but you’re talking significantly more money than AliExpress and xAC. I have to think that an offline access control solution for a single door with some customization could be had for under $100 without any security flaws…but I may be wishing. I’ll post in the Reddit Accesscontrol group soon and see if they are aware of anything.
Me and donfire play with arduinos… and dons super clever. Some great sugestions to start. I like the idea of a dip switch or jumper pad to set usecase. On time off or flipflop.
I had not considered 2 readers. But is easily done.
Limit switches as a periferal. as back stop is also not a problem
If u want a dual frequency readers. Somone will need to point me towards a suitible one . Or i can knock one up with the rm6300 and a pn532 or rc522 mini.
As for simplicity. I will aim to make this plug and play for ya.
But befor i even consider all this extra work. Can we just reflash the xacv2 with new code that fixes the security issue?

I have a literal spec sheet I created for an access controller I’d want to build… I’ll dig it up.
Also yes, it would be possible to flash if you have a JTAG programmer and I guess some source code to flash into it… but that latter part is the difficult bit.
