good project
i love it, congratulations

Dont forget to get a t-shirts!
Only 48h left!

By all means,get some rest man 

Enjoy!!!! I did!!!! 

Take 3 days...

You need the time off to enjoy yourself n'est pas?


Edit: Vacation Pic.

So, looks like my vacation next week will be cut short and I'll be gone for 1.5-2 days instead of 3, which means I'll probably have time to doublecheck the new 18-chip test board and send it off, and maybe play with Compac tweaking as well. We just got a parts shipment in which includes stuff to play with the big regulator for the TypeZero boards, so I might make progress on that next week also. Should be fun.

It is definitely going to be fun to have a full product line with two stick miners and probably two full-size mining boards for around $1000 in R&D budget. I think we've spent about half that much so far, maybe a little more. By the time all the TypeZero boards are done we might be up to $1500.

It's quitting time now, pretty sure I got the 18-chip initial board done. It's set up to take in an external Vcore and external drive signals from either USB/UART or S5 controller (requires changing a jumper to switch from one to the other). It's all one-sided, so initially we'll be testing how well it cools through the board (and hopefully nothing shorts out). If necessary I can shim the ASICs, switch the node-level bulk caps to the backside and reinstall it with top cooling.

I'll probably have to strip down some of those donated dead S5s if I want to populate more than one board; I think I only have chips enough for one. Actually, I got one intact S5 working out of the batch and it's mining for the museum, which is fun. The other four full boards I have should hopefully yield enough non-smoked chips (one board sorta works, so that's 30 right there) to populate a whole S1 worth of boards, if we can get software working to handle multiple chips and multiple devices. Unfortunately I probably won't be able to go over this board and verify everything before sending it off to prototype until early next week, but if it works is gonna be pretty great. All we have to do after that is design all the peripheral controls and tack them on in the extra space at the top. While waiting for the protos to come back from the etch house I'll probably jack with Compac and maybe take a look at some of the stuff Novak's working on.

In the words of the science guy from Independence Day, "this is a very exciting time."

This is exciting.  Great progress.  Although you've mentioned you don't things have been moving along quickly, I really think, in a big picture, they have been moving right nicely.  Look at how close you are now to having multiple products.

In a way, it's a compliment if Bitmain didn't want to sell to you.  It would be most likely, that they're concerned you are a viable competitor to them.

Thank you Sidehack & Novak.  Keep up the GREAT work!

I do not believe realising the ills of your ways (and taking the right turn) two months ago won't hold you in good stead ..... just don't go gouging that healing wound two months on as I am pretty sure they would neither mind price gouging you nor ever seeing your project come good !

Well, as soon as I get around to ironing out the Compac issue that product will exist. And once I know it works, about a day later I can be sending off for Amita prototypes. And as soon as I can successfully test prototypes of the 18-chip board I'm 80% done designing, and using that as a base we iron out the hard/soft requirements for fan speed, temp sensing and voltage adjustment on it, that product will exist as well.

Well, now you've heard the condensed facts from, so to speak, the horse's mouth, you do not have to recall at all.
But that was a side issue, the main point being, as we speak, there is no sellable product for which to request batch pricing on the chips, so I am not surprised they have not prioritised responding to speculative emails (bearing in mind BTC value ..... and its fluctuation).

I had no qualms at all about voicing my opinion regarding their price gouging on the S5 a while back. If they don't like me saying their chips are the best available and their hardware is well made but their greedy/opportunistic pricing strategies are unfair to everyone, well, not much I can do about it. I would like to work with them but I'm not gonna be a yes-man and pretend that everything they do is right (leave that to the Apple fanboys). I'll honestly say that most of what they do is right - my opinion, I like more of what they do than all the other currently-operational manufacturers. But if speaking against their price-gouging two months ago gets me in hot water, well, this project will have to go somewhere else.

when did sidehack label them.  I do not recall that in any of his threads.

Bitmaintech was not and is not terrible or unethical .

As of this moment pretty much the best asic company in the game.

I can't blame them for not responding given the depressed value of BTC of recent .... and seeing you are no where near a sellable product it'd be a simple case of asking them to speculate on the possibility of selling a certain size batch to you.
Saying that, labelling them unethical in their practices may already have put paid to any possibility of getting a decent sized batch of chips from them at a competitive cost, if ever (even if at all!) you came up with a real challenger to their very own S5 design .... and who'd blame them.

That's actually two four-chip units running. One's on a USB adapter with the U3 driver, which for some reason sends duplicate work to the second chip so though it's running 16GH I only see 8GH worth of shares. The other is off the S5 controller, which I think is thrashing or wasting work somehow (probably due to some lines not being connected and it only having 2 of 30 chips present) so about 1/3 of its shares are rejected stales. If both were working I'd see 33GH off about 12W but since I'm losing 8GH + 6GH between the two (probably software) issues the pool only sees 19GH of good shares.

Same reasons as explained about nine posts back. I haven't changed the setup at all yet. Given what else is on my plate the rest of this week, and being gone half of next week, it might just stay there and run for a while longer before I mess with it again.

nice numbers above a stable 19 gh


 6 to   7 watts  for this testor?

Me neither, and I really hope we can work stuff out for chips. Bitmain never responded to my last couple emails so I'll have to hit them up again soon. I also have about a dozen S1 that were undervolted last fall I finally turned off about a month ago. If I can get an 18-chip test board drawn up today will be a big step toward the TypeZero.

I, for one, can't wait!  I recently turned my S1 off, it wasn't worth it to me any more to be running it even as a solo mining lottery ticket.  Can't wait to see what this upgrade will do for it!

I haven't seen any post that chips are available and deal made of them?

I have two S5s from early batch and would like to have some more but price of miners + shipping + 24% sale tax ( +possible 3% import tax and low value of BTC) kills ROI totally.

be patient hold on to the s-1's and he will have the upgrade kit ready for you and me and a lot of other people.

I'm interested to uprate some of my undervolted S1s, summer has arrived and heat is not anymore needed.
Do You have a deal for big patch of chips?
