The most annoying thing is when CGMiner just decides to randomly shutdown on its own. Especially when you're away for a 2 week Holiday, & it decides to shutdown right before you board your flight after you spent a TON of time setting everything up in preparation! (true story)
I've seen this with all versions of cgminer I've used, both on Windows and RasPi. "fixed" it with a simple shell script that restarts cgminer whenever it stops... I found a MUCH easier solution for Windows - All you need to do is add CGMiner as a Windows Service & then tell it to restart if/when it closes! Not sure what the file was that you sent me ppetrovic68, but it came up as a "backdoor" virus.. I never sent any files, what are you talking about? :/

Most of the additional tools I needed to work up heatsinks have arrived. The heatsinks are only 6 fins instead of 8, but should still work well enough. I still need to build a jig for drilling, but my power tapping head arrived today so a bit more testing to dial it in and we should be in business.
I finally got around to checking out the robot program, making sure all the feeder alignments and parts rotations were correct. Tomorrow I'll have to run through it to check the actual parts placement calibrations but that takes a lot less time. Tomorrow I should get all of the prototypes built and start testing. Hopefully I'll be getting sample sticks out Friday, including one for philipma1957 to review.
I'm assuming that the PCBs will be delayed a bit, partly because they were expected to ship today but I just confirmed the panelized gerber layout yesterday so I doubt they've been made yet. Shouldn't affect much in the long run.
I still haven't gotten out BW sticks, parttly because they're entirely manual placement and that kinda sucks and partly because I've been juggling a lot of other stuff. Yesterday's workload didn't finish until 1AM. I took Sunday off instead of making progress but that's because I'd worked the previous 13 days. Anyways, once 2Pacs are rolling off the line I'll be giving a free 2Pac to the people who bought the BW sticks to help make up for the delay.
Once Chinese New Year ends and the cheap-but-easy prototype PCB house gets back to work, I should get some Biggie prototype PCBs to play with. I probably won't get around to building them until at least the middle of February because the robot and I will be quite busy with 2Pacs. There won't be a lot of retooling for parts feeders, but it will take a full day to get the placement program made and calibrated. I don't have the numbers offhand, but there are at least 40 parts per node and 5 nodes in the chip field, plus the fan control, USB interface and core power. Looking at around 250-300 components to verify placement and rotation on.

Finally got around to building a test 2Pac with good chips and ran a quick efficiency test, only up to 300MHz because my USB power meter is only rated for 3A. Freq | GH | Vcore | Power | J/GH | 100 | 11.00 | 1.26 | 3.67 | 0.33 | 125 | 13.75 | 1.26 | 4.48 | 0.33 | 150 | 16.50 | 1.26 | 5.27 | 0.32 | 175 | 19.25 | 1.26 | 6.12 | 0.32 | 200 | 22.00 | 1.32 | 7.43 | 0.34 | 225 | 24.75 | 1.36 | 8.73 | 0.35 | 250 | 27.50 | 1.40 | 10.11 | 0.37 | 275 | 30.25 | 1.46 | 12.25 | 0.40 | 300 | 33.00 | 1.50 | 13.98 | 0.42 |
At 300MHz, the total device efficiency is only about 15% worse than the datasheet chip-level efficiency, which I think is pretty good for a stick miner. It also puts up over 30GH, which I think is pretty darn good for a stickminer. Note this is about the same power draw the original Compac expected to see at 22GH, so we're seeing a 50% improvement in hashrate. If the stick could be pushed to 400MHz you'd see it drawing about 23W for 44GH, but I don't want to test this until I have a bit stouter measurement tool. I'll copy this table into the OP for reference.

Hello Sidehack,
Do you have any temp reading yet ? I would be curious to know what is the chips temp at 200 and 300MHz.
Best,

No, I don't have good tools for that. What I do have is a cheap case fan capable of cooling a couple dozen sticks.
The BF16 stick will have an onboard temp sensor, but not this one.

A fairly stable version of the gekko driver I've been working on has been released in my repository for early adopters. git clone https://github.com/vthoang/cgminer.gitThe 2Pac(s) are not shipped yet, but feel free to compile it and run it against the original compac(s) if you feel brave ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) . For detailed instruction on compiling and running it, visit the new 2Pac thread here: https://bitcointalk.org/index.php?topic=1764803.0

Thanks for the hard work and support for this project. I have been running your cgminer 4.10.0 build with original Compac sticks for a few hours now. Sticks are running at the clock speed of 343.75. At this clock speed, they should reach around 18.9G. However, they average around 17.6G instead. Just sharing what I've noticed so far.

Thanks for the feedback. I'll check if I can replicate that this evening.

2Pac PCBs arrived today, actually earlier than expected instead of the other thing. I got ahold of them because I was trying to order solder paste stencils as well, got that taken care of but I don't expect them before Monday. I should have time tomorrow to get the robot set up to run a full panel so Monday we can dive right in. One minion drilled out about 300 heatsinks today, and another helped me strip about 1200 chips from S5 boards, so that's pretty well on pace.
Proof 2Pacs will be sent out tomorrow, to CrazyGuy, HolyScott and MacEntyre (the big resellers) and one to philipma1957 since he offered to do a review.
I need to get the sales queue updated, since a few more orders have come in this week.

will be showing review with direct comparison to a 1 pac.

Stencils arrived this morning so we got started on surface-mounting. By tomorrow I'll have about 600 sticks with ASICs mounted, and will have started on the topside components. All heatsinks are drilled and tapped and ready to be installed. Overall, we're right on schedule.
I also happened to fetch some materials to play with anodizing a bit if I get some spare time in the next couple days.

Awesome! Keep us updated, I don't know too much about miners and how they're made but I'm always willing to learn more about em. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Sounds like it'll be business as usual with the miners.

Awesome news, can't wait to get my hands on these. I have everything set and running my compacs now with vh's new cgminer. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) I should be all set to just plug-n-play when I get them. ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)

Awesome, can't wait. Sounds like a lot of fun to design and manufacture.

You have active or passiv cooling? My setup has a stud hub from klintay that I modded with a superior psu inside it. Mine was a usb 2. He now sells this usb 3.0 version http://www.ebay.com/itm/Eyeboot-19-Port-40A-USB-3-0-Hub-110-240V-2-amps-per-port-/351720554389?I do not know if he went to the better psu inside it but it is easy to upgrade the psu if it is like my hub. This hub would be sweet with 16 2pacs. I think you would not need the bridges I use since it is a usb 3.0 hub I set volts to 5.5 on the psu. With the bridges I can pull 1.8 amps safely so 1.8 x 5.5 = 10 watts with ease. Based on all the work I did with this hub a year or so back running the compacs I can do freq 350 non stop with the compacs and a proper fan the new setup in the garage ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FHK7aPoN.jpg&t=665&c=IOZIXjgCLVimtg) both sticks using 2x ports ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FUqMrYUB.jpg&t=665&c=jk4XJ2MFCZhTKw) the first setup only the 2x chip is using the 2x port bridge ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2Frh0WCCy.jpg&t=665&c=ZPfhwwp0xwL84g)
