Quote from: antirack on February 25, 2012, 01:37:48 AM Unless BFL doesn't give a sh*t, then they'd send the parcel from a private address with a private name and say here's your 'magic electronics' you forgot at my place during our new year engineering session at my house. But I doubt customs would fall for that. Maybe they could pretend it being an RMA, but customs may ask you for proof that you actually sent something to them and that you paid tax when you originally bought the item. Might work for a second unit though, you could just pretend you sent your first one back and thats the new one (they will probably ask for a receipt to show you actually sent something back). Either way, you are screwed if you live in Europe ;-) Frankfurt in Germany is a good and relax place to ship parcels... Quote from: cablepair on February 25, 2012, 01:57:57 AM BFL is obviously so overwealmed by the Bitcoin community that they aren even answering their phones or returning emails at this point, lets help it turns around soon , I have been trying for two days to place an order for 2 BFL singles via dwolla and I cant seem to get ahold of ANYONE We apologize for any inconvenience. We've been processing orders as fast as we can, and catching up with all of the inquires without delay has been proven to be a bit difficult. We will send your order details as soon as it is possible for us. Regards,

Quote from: nbtcminer on February 23, 2012, 07:16:03 PM This runs true for even those people who live in cold climate countries / areas; running an FPGA card in a heated room can result in poor mh/s. 22C is a good temperature but real world ambient tempuratures tend to be much higher. The BitFORCE can operate up to 27C without throttling (or perhaps 20 max seconds every 12 minutes). Beyond this temperature, the unit may go through throttle cycles more often. This may be improved very soon. We'll do our best to keep the community informed. Regards,

Quote from: DeepBit on February 23, 2012, 03:58:59 PM +22C recommended environment ? Oh, I'll never be even close to have a chance to use BFL single Hello Deepbit, We were wondering, what is the actual environment temperature you're operating in? Regards,

Quote from: antirack on February 23, 2012, 10:54:10 AM I don't know if temperature sensor stickers exist and can be used (kind of like Telatemps, but a bit different). If they do exist, you can put a sticker on all your singles and the one that gets cold is the one you are looking for. Kind of like this would be cool: The actual firmware supports temperature-monitoring, and the miner software can access it. We may add a blink-on-user-request feature to the firmware. This way, any unit that the miner asks for, can start blinking at a fast pace, making visual detection of the unit-in-question easier. Regards,

Quote from: nmat on February 23, 2012, 10:17:52 AM Quote from: BFL-Engineer on February 23, 2012, 09:47:16 AM Greetings, Regarding USB limitations, out of each real USB port (a port that directly comes out of your motherboards southbridge, not an internal HUB), around 100 units can function without restriction. Thus, if your computer has 3 real USB ports (EHCI or OHCI), you can hookup around 300 BitFORCE units to it. BitFORCE does not take any power from the USB port it connects to, and acts as a stand-alone self-powered unit. Good Luck, The thing is, if you have 100 devices connected to the same USB port and one of them has problems, it's gonna take a while until you figure out which one is it. Or am I wrong? It really depends on whether they are all BitFORCE units or it's a mixture of different devices (Mouse, WebCam, HDD, etc). We had no problem connecting many units to the same USB ports using HUBs. It is not recommended, however, to connect a High-speed and Full-Speed or Low-Speed device to the same port (This applies in general to the USB protocol ). The reason being is that the controller must reduces bus-speed to send SOF (Start Of Frame) packets or data packets to full-speed/low-speed units and switch back to high-speed again. This will reduce overall efficiency of the bus. Regarding trouble-shooting, that is something to be determined based on your specific setup. Generally, if a USB 'device' fails, the HUB disconnects it and it goes offline. Regards,

Quote from: payb.tc on February 23, 2012, 02:31:49 AM giga, have you ordered any more? one thing i'm curious to see is how multiple 'singles' would go being run on 1 pc. would there be any bandwidth or power issues with the usb port?
