Seriously?

Took me less than an hour to analyse the work data control necessary for an S19 chip.
Of course someone else spent many hours connecting up all the hardware to dump and format the data so I could do it,
but if you're gonna say it's that hard without trying, then I'd worry about anyone using anything you built.

While 'we' do already have the info to do a 3rd party miner with the chip, unfortunately it's not a priority at the moment Sad

Ok, now try to do it without access to miner (and a pool(emulation) so you know what data is send to the chips) Wink

I've got a diy logger, but no miner.. The hardware side is not a big problem though.
I've done my part in dissecting protocols and the underlying meaning of the data that goes over a unknown bus by analyzing the communication of the meade autostar system and constructed a meade compatible servo and stepper motor driver for astro mounts and I'm sure I could do likewise with x19(+) miners, but without a miner??
I do find it strange that info on X19(+) miners isn't available years after the release of the miners.

On my standalone BM1397 miner; the revised revision Wink

pcb's have arrived and I've built one prototype. Regarding the cost (if you desperately want to know), the bom is something like this (missing the usb connector and optional DG301 screw terminal):

Most parts are available at jlcpcb (except the bm1397ag) but as good as all parts are extended parts (meaning $3,- per part, ~$100,- per batch of upto 30pcs on top of the part prices).
Efficiency is at 12.5W @ 300GHs when fed with 9V (according to my crappy usb power meter), live stats still on https://solo.ckpool.org/users/1KgwWwBh7qGtcWJ9ZRNTUbVCR1L2qYkzcy (workername": "1KgwWwBh7qGtcWJ9ZRNTUbVCR1L2qYkzcy.test1397_12B")
