I don't see why you wouldn't be able to. As long as the hub can handle the extra power the sticks will come up as their own separate com ports. You will just need a separate instance of bfgminer to run them.

Yes HolyBitcoin and AsicPuppy are the two official US resellers, and bitshopper.de is the official European reseller.

International guys please make sure your including your phone number with your shipping address. Its needed for the customs form.

First shipments are going out thursday details here : https://bitcointalk.org/index.php?topic=1256818.msg13531769#msg13531769

If your one of the first to put a deposit please send in your final payment ASAP so I can ship your unit.

Its currently sold out, but I have 3 resellers you will be able to buy from when I send out their units. I have a couple hundred units I need to send out in front of them though.

Shipments will start going out on Thursday morning. I am currently taking full payments for the first 15 or so orders on the order list. If your name is up to Row #22 you can send your full payment and I will have your stick shipped by Friday latest. Please have your payments in by tomorrow night or I will open up payments to the rest of the people and will have to skip over you. Keep in mind I will be out of country from the 16-23, so whatever I don't ship out by friday will have to wait until I get back.

Payment/Shipping Details

Final price for the stick is 32 USD. To figure out the total price to send to the main LTC address do the following complicated maths

• $32 * number of sticks ordered
• add shipping price
• convert it to the current LTC price (around $3.5 per LTC)
• subtract 2 LTC * number of sticks ordered from that amount

If you have already verified yourself(which most of you have) just send that amount of LTC owed to the public address FROM THE SAME LTC ADDRESS YOU ORIGINALLY SENT THE DEPOSIT and PM me with your TX ID and full shipping address. (if you don't know what that address was just look at your deposit transaction on the blockchain to easily find it.

Shipping Prices:

-All US based customers have a flat $5 fee for up to 5 sticks with standard shipping and tracking. If you want priority shipping (2-3 days) price will be $7 for up to 10 sticks (if you have ordered between 5-10 sticks it will be shipped out priority for $7). If you have more than 10 sticks please contact me for shipping price.

International customers please send me a PM with your full shipping address as I need to calculate it individually. Price will be between $8-15 for up to a few sticks. Keep in mind this price is for First Class International USPS shipping, there is NO tracking and shipment can take up to 6 weeks with this service. Your other option is Priority Mail international which I can ship out up to 10 sticks for $28. If you ordered more than 5 sticks I would recommend this option since it has tracking, and delivers in 6-10 days. I will not be responsible for lost or delayed mail if you use First Class.

I will be adding $10 value to the customs form to keep taxes low, so let me know if you want me to put a different amount.

Unfortunately I bought the last ASICS in existence from this company so this is the one and only batch. I will definitely make more products if I can get my hands on any new chips. I could *possibly* repurpose the miners I have and salvage the chips if there is crazy demand for a second batch, but removing chips from boards is time consuming and costly in order not to damage them so not sure if its even a viable option.

Some more teasers for you guys   More info in the main thread: https://bitcointalk.org/index.php?topic=1248914.msg13521272#msg13521272

Here you go





All the PCBs were finally finished today and assembly is underway. These are the first boards straight out of the oven! (sorry for the crappy pictures they are from my SMT shop that is assembling them). The timing sucks for these because I will be out of country from the 16th to the 23rd, and thought that I would have had these finished way before the 16th. I don't want to make any promises but I'm pushing to finish them up so I can ship them out on thurs/friday, but won't know for sure until tomorrow. It might end up that I ship the first orders I got before I leave and ship the rest out when I get back.

Sorry for the delay, but I did get screwed over with the holidays on my timing from manufactures and parts suppliers. Considering the holidays, and the fact that this is my first "mass" produced board with everything done by me from scratch; I have to say a month and a half from prototype to finished final product is a time I'm pretty happy with!

Yea they are very similar.

I have built a custom bfgminer driver for this, with full support of all bfgminer features (no hacked pieced together driver). It will have auto-detection, frequency settings etc.  Any third party solutions that can run bfgminer as the backend interface will work with these, but you will need to install the version I will provide with the Moonlander driver included. The driver will also be pushed to Luke's main branch, so any miner software that uses bfgminer will just need an "update" run to work with my sticks.

Im compiling the final binaries and putting together a support/getting started thread so keep an eye out for that in the next few days.

wow the PCB glows...you must be using some cool new tech to run these.

Ahh yes I had lots of fun dealing with the transients in my design. At least for the scrypt chip I'm dealing with it was not that bad because the transients occurred at the end of each hash cycle...which for this chip was in the range of 10-20 khz, so even at a 250 kHz switch rate it was manageable and enough spacing to decouple any resonances. Im pretty sure SHA cores have hash cycles in the 100s of kHz, which would be pretty nasty for a 250 kHz buck.

Not until I'm ready to ship your order out. Once I can ship it out within a day or two ill contact people in the order on the list. PCB manufacturer was swamped with year end orders and since I'm "low priority" they still haven't completed all my boards. They are promising they'll ship everything out to me on Friday, so if thats the case ill be able to start shipments by midweek next week.

Final cost is $32 plus shipping.

Yea I can't wait to get my hands on these. You guys probably didn't notice but I used 2oz copper on the production version. I was getting around a 50mv voltage drop from buck to ASIC at full power draw of around 10 amps on the 1oz prototype boards. This translated to almost half a watt of wasted power and extra heat. This will be cut in half with 2oz copper so final product will be even more power efficient!

Does the BM1384 have isolated ground lines on the IO? If your changing core voltage on the string won't that shift the relative ground voltages and throw off your IO dividers? Unless your just igorning it and it operates fine with IO voltage going from 1.8v +/- 200mv or so.

Numbers have been up for a while from the prototype sticks. Check out the main thread in the Alt mining section.

Try sticking a 10uF on VDD and see what that does.

Weird...well you shouldn't tie VREG to an external source, since the LDO is powered from VDD anyway (unless you don't have VDD connected to 12v). Do you have at least a 1 uF bypass cap tied to VREG, and a 4.7 uF input cap to VDD?
