Yeah, but a couple of those orders have yet to identify themselves.

I was paid for some gear today..

So I can put in for one tonite.

Second batch I would guess.

I'm in for one. Like Phil I'll be running this one at home. I will PM you when I have sent funds, but probably tomorrow (Tuesday) or Wednesday.

Anyone want to help me figure out how to sign a message?  Maybe I'm dumb, but I've spent an hour trying to figure this out on my blockchain wallet and can't.  I've read this:  https://www.reddit.com/r/Bitcoin/comments/18qy88/bitcoin_message_signing_and_verification/ without figuring it out.
I've found this:  https://support.blockchain.com/hc/en-us/articles/210353833 which states: 

"What is message signing, and how can I do that?

Message signing is a way you can prove you control a particular address, and demonstrate you have ownership of the funds.

This feature is currently only available for your Imported Addresses, but will be implemented for all addresses in the future. To sign a message, go to Manage Addresses to the right of Imported Addresses. Choose which address you want to sign, and click More Options -> Sign Message.

A small window will display allowing you to provide a unique message or signature that identifies you as the owner."

Now I didn't import an address for the transaction, so maybe that's why I'm not getting it?

As of right now, I can get an S7LN shipped to my shop for about 0.51BTC

If I ask 0.59BTC all-in for an S7LN clocked at 620mV cold and 450MHz, for 2TH off about 415W, with fans preset to 20% expecting board temps about 50C and very quiet operation, tested for a full day for stability and the price includes shipping from me within the US, who is in?

If that sounds agreeable, send 0.59BTC to 1CoLDs7XNi8ehyFnGWicUhgBGb7Kw42Ugi and a message signed with that address to me in PM. I'll also need your shipping address. When we get up to about 6 units paid I'll place an order and get 'em sent.

I haven't done any extended tests, but I did determine that the hardware is capable and I have the required data to hit voltages above stock. The full range on the regulator is from about 580mV to 770mV chip-level.

Yes, if you were into that sort of thing. Stock on the S7LN is about 670mV, but I can take it as far as 770 if you want your miner to burst into flames.

Also my S7LN is currently testing at 1.9TH 365W which puts it ever so slightly below 0.2J/GH, at 47C 20% fans.

Probably not worth it, but was curious if you tried it.

Would overvolting be possible?

Of course, it may be just as easy for someone to just buy one and have it shipped to my shop. I'd still need a shipping label so I could send it on once it was worked up.

I spent the last couple days writing some new PIC firmware for my S7LN (delivered Wednesday 8th) and have been testing it. Right now my machine is running 2.03TH and pulling about 415W off 120V, putting it at an efficiency of right around 0.205J/GH for the machine. With the fans at 30% my board temps are 45 and 47 in a 75F ambient and it's not upsetting my TV watching though the outlet of the miner is only about 8 feet away. I can probably make it more efficient with more testing, and I bet it gets quieter.

I'm working on testing other voltage setpoints and will be putting up some efficiency curves and making the code available to anyone who wants to wrangle his own hardware. It'll require a PIC ISP programming device and accompanying software. There's a discussion thread over in the Hardware forum proper about this.

So I mentioned maybe doing a group buy to bring in some S7 or S7LN, and I'd flash 'em to the desired setpoint, test 'em for about a day and ship them within the US. I already have three people interested to the tune of 5 machines. I'm thinking of gathering coin for set of about 5 at a time plus shipping to my facility, plus about 0.05BTC to do the work and testing. It'd be nice if I could get a shipping label for them as well, but we can work that out. Any import duties would also have to be worked out, which is why I was thinking of keeping orders limited to 5 units.

The current plan is to send $420 worth of BTC to address 1CoLDs7XNi8ehyFnGWicUhgBGb7Kw42Ugi, and PM me with a message signed by the sending address and I also need your mailing address. If you would rather use PayPal or some other payment method, let me know. Machines will be set to 620mV cold operation (630mV if 620 is not stable) and 450MHz for around 420W at 2TH, unless otherwise specified.
