1 MH/$ is way less than I expected, but still very good!

Expect a rally of mining difficulty, guys. Grin

1, price.
500 USD for one, and will lower up to  20% if your order is large.
Will you be accepting Bitcoins (and/or other payment methods) this time?

Its better than Icarus but i dont understand why not offering quad FPGAs. Much cleaner setup, less power cables, and USB cables.

Temperature and fan control would be a huge improvement over Icarus.

Any changes to the protocol? ACKs when jobs are done?  or still waiting up to 11 secs for response?

because we have a future plan, set up a rig by 8-16 Lancelot on a single mother board (which is less than 200USD cost), this cluster only have one 220V power plug and LAN ports (RJ45 and WIFI).
so until now, i still consider 2 FPGAs pre board is the best structure for balance the cost, size, yield, etc.

i must say, icarus protocol is simple but efficient. by this protocol, one 20$ router can handle up to 70 icarus boards with a CPU usage under 10%. why all of you think we must improve this protocol?  Grin
certainly.... i must do some modify to support added functions.

No need to improve. It works. And works well.  If you keep the protocol the same, all miners (cgminer included) that support Icarus today can just implement the extra "fan set/read speed", "temp read" commands and support Lancelot with little change to their mining code.

Does it work well with p2pool (with new workbase given on average every 10 seconds) ? GPU miners can choose the amount of work given to a GPU to control the latency which makes most of them able to work well on p2pool, is something equivalent already available or planned for the icarus protocol ?

certainly. this protocol can push new work to FPGAs at any time. and FPGA will handle it at that time.

If I were to give you enough money to purchase 30 Icarus and 30 Lancelot miners today, what would be your estimated delivery date for both orders given everything you have today? (I do realize you still have a lot of development and it might be hard to estimate, but I figure it is still worth asking, in case I want to purchase Icarus for possible use or resale.) Thanks.

500+ mh/s for $500 or so??? Even without any warranty I may be in for some  Grin

Good Luck !!!!!!!!

Can you explain why you're excited when BFL offers more MH/s/$?  I like having competition, but I'm not getting it?

Well,as you know BFL's shipping time is,hhmm,slow........& the lower wattage of Lancelot is a +.

But mostly,all but BFL's hash rates are pretty low=long ROI.Almost $600 for 300+ mh/s takes close to 15 months to recoup investment.

I hope to encourage higher hash rates by investing Cool

Also being unemployed,I can only come up with $500-$600 a pop  Embarrassed

Yea but you can save up and buy a BFL single. Lancelot should've been at least 4 Spartans. There are 3 competitors that offer good prices (Well 1 out of 3)

1: https://bitcointalk.org/index.php?topic=49180.0    <----- $1,359.00
2: https://bitcointalk.org/index.php?topic=79114.0    <----- $1,069.99
3: https://bitcointalk.org/index.php?topic=78239.0    <----- $640

All these are Quads. They also got doubles.

PS. Kinda have to go, I'll post more info soon. Don't kill me just yet lol.

Small problem, BFLs use twice as much power per mhash and thus take much longer to pay themselves off, and you also have to start paying attention to cooling problems as well.

Simple as that: They must have found a way to get chips that usually cost $2000-4000 each for less than $200.

Some people think they've found a source for used or unwanted chips, which is pretty sneaky^Wbusiness savvy.
