Hey guys and gals!

We're picking up a few (hundred) of Bitmain's latest gadget, the "AntMiner Jumper Switch (https://www.bitmaintech.com/productDetail.htm?pid=00020140731043909819C9CL7qf4064A)" PSU plug.

I'm gauging interest in a GB for BITMAIN's PSU Jumper Switch which was announced today, July 31st.  This buy has been cleared for launch, and our order has been placed.  We'll hold units for anyone interested on a first-come, first serve basis.  I would like to have some units on hand myself, but the MOQ 500 is a few more than I would like to have lying around.

As I have no trust rating, I'll be happy to accept Verified Paypal accounts or escrow for this project.  If a reputable escrow provider is interested in throwing in on this one, please feel to PM me--else wise I'll hunt one up or take suggestions from the participants.

If you're interested in purchasing a few, let me know how many you would like in this thread (or via PM) and we'll sort out the details.  I'm located in the central US, and have current capacity to package and ship the orders upon arrival in no more than 48 hours.  BITMAIN is stating that these will ship at the end of August, and they generally hit their windows or ship earlier.

Pricing is calculated in US dollars per unit, and doesn't include shipping costs.  In the US you can send me a PDF of the postage, or I can calculate the rate and settle up before we ship.  We have numerous anonymous commitments, so barring any difficulties this GB is already GTG.

Payments must be made before we ship the product, but you don't need to pay in advance if you choose not to.  All prices are listed in USD below and will be priced via the Bitstamp market price when you decide to order!

-----Pricing-----

1-10 units . . . . $2.25 per piece

10-25 units . . . $2.00 per piece

25+ units . . . . $1.75 per piece

-----Shipping-----

We'll settle up on shipping in the next week when the product arrives, but I'll accept pre-printed postage from any major carrier (I prefer USPS or FedEx for domestic) or charge a flat rate in BTC.  It'll be cheaper to provider your own postage, and more convenient to pay the flat rate.

[Update Mon, August 11]
Each unit, according to BM, weighs 18.5g a piece, or about 0.66 ounces.  For US customer, that comes out to about 24 units per pound, which means we should be able to easily ship units in a Priority USPS flat rate box.

Now, what we don't know is how these devices will be packaged, or if they will be packaged at all.  BM has verified with me via email that each piece will be individually packaged.  The plan currently is to receive the units and determine how many pieces can be fit in a small/medium/large USPS flat rate box with appropriate padding to prevent units from being damaged.  I will provide bubble wrap and the like, as I have those items in stock now.  As soon as we determine how many units will safely travel in each box, I'll contact each buyer and make arrangements for shipping.

Cheers.

Was considering doing this myself. Put me down for 20.

They do not look safe.  
Cablez makes them that won't zap you if you brush up against them.
Still it is much better than a paperclip.
What do they break down into per unit?
Sorry I see now.

The pins will carry the entire 5v amps of the psu.  what happens if they hit the s-3 shroud?

a short, a ground,a dead psu, a dead s-3 .  what happens if you have the miners on this rack?

and the pins touch the rack.

mstrongbow has a 3d printer


I sent him a pm asking if he can print a case /back plate for it,

so if the op and mstrongbow get together on this it is a nice match up

This is a great idea, I'll ping him this afternoon.

I just have to say they are cheap at $1.50 each at quantity but damn are they ugly.

I could just as easily put an LED on mine and it would be so much prettier, lol.  I wish I had my own Chinese factory workers to make stuff so I wouldn't have to pay retail for everything. :(

if he makes a backplate I will buy 4-6

at cablez i like the  bright colors find it amuses me.  I also think down the road if I sell the s-3's on ebay and offer these as a bonus it would help make a sale.

They could probably even help S1 sales. People like "free" things bundled  8)

I am with you there.  That is why I buy my cables and adapters from you.  No shocks and worth the money due to the quality.
If I had the money I would invest in a US based company for you and for mstrongbow.  That would be a great combo.

I've shot him a message, we'll see if he's interested and what we can come up with.

I would also like to second that Cablez makes an excellent product, and member of the forum should always consider his products for their mining endeavors.

Sounds good.

Order has been placed with BITMAIN.  We still have ~180 units available for purchase.

Heya bro, just replied to your PM. Count me in for 20x units as well.
 8)


And yes, I plan on designing enclosures for these!

Just shot you a PM, thanks for getting in touch!  I'll add you to the list, which leaves us with ~160 units available.

I've contacted BM regarding the dimensions of the product as well as the weight of one piece for shipping purposes.  I'll relay the information as soon as it's returned.

Just sent you payment, feel free to forward any specs to that email address as well.
Thanks mate!

I heard back from BITMAIN overnight, and I shot you a PM with the dimensions.  Let me know if you need any additional info.

Thank you for the message.

I'd like to get in for 20 as well.

Hey guy, we've got approximately 120 units still available.  Shoot me a PM or post here and we'll add you to the list!

Pm sent.

Thanks for the orders, people.  We've got approximately 70 units still available.  I heard from BITMAIN last week regarding dimensions, and passed those on to mstrongbow so he could look at building an enclosure for those of you interested.

Each unit, according to BM, weighs 18.5g a piece, or about 0.66 ounces.  For US customer, that comes out to about 24 units per pound, which means we should be able to easily ship units in a Priority USPS flat rate box.

Now, what we don't know is how these devices will be packaged, or if they will be packaged at all.  The plan currently is to receive the units and determine how many pieces can be fit in a small/medium/large USPS flat rate box with appropriate padding to prevent units from being damaged.  I will provide bubble wrap and the like, as I have those items in stock now.  As soon as we determine how many unit will safely travel in each box, I'll contact each buyer and make arrangements for shipping.

I still owe three people PayPal invoices--I just returned from an impromptu holiday weekend and will get those out shortly!

Invoices sent to those that requested them!

I sent BM an email yesterday and they confirmed that each unit will be individually packaged, so they should be easy to ship.

Hey guys, we've officially sold out of this GB--thanks to everyone who participated!

I'll update this thread if someone drops out, and keep everyone apprised as to the shipping status.  As soon as we get the shipping notification from BM, we'll update the thread and start preparing to ship to everyone.

Feel free to contact me at any point.

Cheers.

Awesome, thanks for keeping us updated  8)

 At op I am on this list for 6 I have not paid anyone so far. 

At mstrongbow  I would want the back plate.


not sure what I need to pay  or how this will develop

but I am in for six switches and 6 back plates.

Sweet bro! Yeah I will have a couple different versions of these jumper cases available shortly after receiving my units. I am thinking a combo enclosure...Bitmaintech jumper switch and r-pi combo.

Philip,

You can pay when they arrive, or you can pay now before they arrive.  We're going to sort out shipping once we determine how many can safely be shipping in small/medium/large Priority USPS boxes.

Your 6 units are allocated from the 500, and they'll be ready when you are!  Shoot me a PM if you would like to sort out shipping, we can probably work something out for 6 now.

Mr. mstrongbow will be building plates for these units once his arrive!

Cheers.

Payment sent.

Received, cheers!

okay may as well send my 6 right to mstrongbow   saves double shipping.

send  me a pm with a btc bill.

 then ship them to mstrongbow.

At mstrongbow   is this okay that my six are sent with yours?

Cool with me broski  ;D

thanks

i would like to join this group buy

i know it is closed but maybe some people who ordered 50+ items are willing to pass few for me

i am interested in 10+

thanks

I'd be willing to let go of 5 pieces from my order of 20 ;)

I'll send you a PM, Philip, and make a note to send your 6 to mstrongbow.

All of mine have been allocated already, but there are plenty of people here that may be able to help you out!

sounds very good
thanks!

thank you very much.
how to succesfully transfer part of order?
thanks

Just remind me after shipment announcement and I will grab your info and you can pay for the units at that time.

ok please pm me then

 

got the pm sent the coin just looking for an update thanks!

Bitmain updated their site today with the following:


I'll let everyone know as soon as these ship, and we'll still plan on getting them out to GB members within 48 hours!  I appreciate everyone's patience in the matter, and am happy to field any questions in the thread or via PM.

Cheers.

Happy labor day, people!

I've received a tracking number for our order this morning, and I'll get it posted as soon as the label is moving--it currently just shows that the label has been created.

More details as the shipment moves--its does note arriving in two packages of a total weight on 5KG.

Cheers.

Good afternoon, people.

UPS tracking has been updated, and it looks like I'll have units by Thursday night of this week.  We're going to work that evening to get everything packed up and ready to go, and will be contacting everyone regarding postage due once we've packaged the individual orders.

As always, feel free to ping me if you have any questions!

Thanks for the update!

Switches are in--I'll be weighing and packaging orders tonight to determine how many can be shipped in what size of box.  I'll be contacting each group buy member in the order we've listed in OP.  Stay tuned.

The switch is well constructed and the solders are tight and professional--my initial opinion is high.

Cheers.

That is great news.
Now to get mstrongbow on a case for them.  8)

Everyone should have a PM--please get back with me as soon as convenient and we'll get these shipped.  The breakdown on shipping via USPS flat rate boxes was rather uneven:  a small can manage 15, a medium can store 100 and the large can move 200.  For those of you that ordered between 15 and 100, we'll use larger poly-bubble mailers to get them to you cheaper than the medium flat rate box.

Cheers!

Updated OP with SHIPPED status.  I wasn't able to make it to the PO on Saturday as planned, so everything arranged over the weekend went out Monday afternoon and is in transit!  Please feel free to drop a line here once you get your order and let us know what you think of the devices.

Cheers.

Just got my shipment today! Will be getting on the design work asap.

Once I can locate my digital caliper (micrometer) I will spec these boards and post the details. Dang thing seems to have vanished! lol


edit: 

Bitmaintech Antminer Jumper Switch measurements

77mm x 35mm x 29mm (LxWxH) and 18 grams in weight (0.63 oz.)

Can I get an update on my order? It does not show shipped in the main post and the last PM I received from you was on September 6th saying you would get back to me on first class shipping.

You've got a PM!

I want to take just a quick minute to thank everyone who participated--it was a good experience for me, as I hope it was for each of you.

Have a great weekend!

thanks for doing this.   now I need to talk to mstrongbow

I will be working on my design for these switches this week, just got back into town!

 

sounds good let us know when you got something.  You should have 6 of my switches at your place.  I have 2 more in my house so I will need 8 of them all told.

Yeppers, I have your switches...I should have something ready for show n tell shortly as these should be pretty simple and I have a good idea of what I am going to do already.

Received mine a week ago today. Perfect timing as I left for a trip the next day. Thank you, TracerX.

mstrongbow any thoughts to files or printed cases coming out?

My pleasure!

I will have some updates closer to the end of the week  ;D

Cool I'm looking forward to getting 5.
Keep up the great work.

I am waiting on your updates.

I need a switch, but need a cover for it, before I invest in the S3+ :-)

( I actually assume the switch will work with  S3+ )

It will work with a standard ATX PSU that you would use to power a S3, yes.  That said, the group buy is closed and we're not shipping additional units.  Someone may be able to hook you up here, however, as a number of people ordered numerous units!

Cheers.

Just finished slicing the case model for these switches...should have a working model and pics tonight!

Any requests for mounting options for these cases?

Right now I have a basic enclosure with no means for attaching to anything...I was thinking at a minimum a few holes for securing the unit with zip or twist ties??

You input is appreciated.

Here is a screenshot of the case (and switch) I modeled the switch (very basic) to facilitate faster case design in the design program I utilize (Sketchup)

http://i1141.photobucket.com/albums/n596/MZStrongbow/Mining/AntminerPSU-JSCasepreviewss_zps034c21ad.png (http://s1141.photobucket.com/user/MZStrongbow/media/Mining/AntminerPSU-JSCasepreviewss_zps034c21ad.png.html)

I am printing what should be the final revision now and will have completed pics later this evening.
So far I am pretty happy with the design and they will be more of a permanent enclosure and will require glue (or acetone) to lock the lid into place. I still need to add the holes for zip/twist ties but I am concentrating on the fitment of the board first (as always).

just gotta add zip/twist tie securing holes and this unit is ready for battle!
here's a quick shot I took with my phone...better pics tomorrow

Looks awesome!

Thanks mate! I am starting the final production ready version print in a few...I have a few of the first version ready to rock out the door right now.

You will be able to find them here...
https://bitcointalk.org/index.php?topic=694666.0

Nice work as always. :-)

Thanks bro! I am probably going to toss the Antminer logo on the lid of these covers so they stand out and are easier to identify. Plus I can make Antminer keychains and such after I get the logo done in 3d.

look good. let me know how much you need from me.  you have 6 switches of mine.  so I will need six cases.

Catching up on PMs etc. today...haven't forgot ya  8) Do you have a color preference for your cases? I am out of black filament until my delivery arrives but have plenty other colors to choose from.

TracerX, would you like a couple cases for payment for shipping my switches? If not, I can send payment your way asap.

well  all the gear you made for me  has been yellow so yellow works.  but blue is also good as is red.
