Is there are determination of hash rate yet on any algorithms? 
very interested.
very interested.thats great, direct your questions to [email protected]

Will slow down won't stop it, we'll just find and update bitstream
Which is included with NR104
Which is included with NR104
actually yeah it will somewhat this algo change for cryptonight is purposely designed to limit the effectiveness of fpga

Won't stop FPGA as they are reprogramable 😁
yeah fpgas are killing those algos, cant wait for the xmr fork or more progpow forks
Would like to know some hash rate on the trendy algo like x16r, x16s, x17 etc. No wonder my profit is dropping like juice.

we have posted a new "white paper" on site page of the NR104

* What are all the coins could be mined in this and what is the profit ratio? depends on coin, we making a bitstream for c7 & heavy then next will be for eth (eth 1.4g per card x 4) once we get this bitsream error fee your ROI will be 60days
Please expand. 1.4g per card, times 4, currently makes $120/day. At a price of $25K that's over 200 days to get your money back, not counting power costs.This is based on today's math with today's coin prices. Not fictitious potential future prices.
NB: I'm not saying that 200 days is bad. I'm saying your 60 days claim of ROI is simply not true.
As more details comes regards to our bitstream I will post them public, until then is still in beta. I like to keep conversation based on product NR104 as it can be used with any other bitstream.
I will make a new thread later about bitstream conversation and stats of of them.

It's ready to ship for 25k$ or it it a preorder?
A2. depends on bitstream but each card can max out to 320 watts each x 4 + mobo, ram, hd, fans (making sure we have room for all above to work if is in full load)
8pin
The power may come from 3 sources:
PCIe x16 75 W
6-pin 75W
8-pin 150W
Thus, the maximum power consumption of the graphics card with 1 8-pin connector and 1 6-pin connector can reach the following values: 75+150+75 = 300W
How will you feed up to 320 watts through the 8 pin connector on the USB interface?
The problem is not the connectors and not in the specification. The wires of the power supply are designed for a maximum load of 250-300 watts. But they are not able to work under such loads all the time. The wires will heat up and melt, and this can cause a fire. Many newcomers burned their farms because of ignorance of this.
If the FPGA consumes more than 150 watts, the USB interface is dangerous for it.

you wrote
Interface PCI-E, USB
Power 75W PCI-E + 150W 8-Pin AUX
In the photo I see that you use the USB ports as the ports of PCI-e free.
USB 2 0 - 5V 500mA or 2.5 for each port.
USB 3.0 is 5V 900ma, or 4.5 W per port.
Why use a 1600 watt power supply for this configuration?
Will the USB interface be suitable for other algorithms?
What is in the M2 port?

Hello will answer your questions as it follows
Q1. In the photo I see that you use the USB ports as the ports of PCI-e free.
A1. Correct they are controlled by usb not pcie
Q2. Why use a 1600 watt power supply for this configuration?
A2. depends on bitstream but each card can max out to 320 watts each x 4 + mobo, ram, hd, fans (making sure we have room for all above to work if is in full load)
Q3. Will the USB interface be suitable for other algorithms?
A3. Yes depends what bitstream you use
Q4. What is in the M2 port?
A4. none, we have M.2 to Pcie will be removed later time
Is there an easy introduction to FPGAs? Even as a hobby could one "bread board" together some old gear and get it to hash equihash BTG?
What are the requirements to learn this hobby the least amount of money and is more geared toward learning FPGAs?
