That is really aggressive Phil. I look forward to seeing you do that.
The spec sheet on the chips show it can go very low indeed and the boards and controllers are much better.
This is going to be fun.
We have an incoming $3500 payment from a customer coming in.
I have ear marked this money to buy a small quantity (~1K) of chips from BM, assuming they decide to sell some.
Having said that, I'm a slut, if any other chip supplier has a suitable chip for sale prior to that they'll get the $3500 (first come first served).
Whomever's chips will be shipped to GS (with their approval ofc) for insertion onto hash boards.
We assume that a certain number of chips would be destroyed n the development process.
Once a suitable design is manufactured and field proven we'd be up for a real quantity purchase of chips (and then boards, ofc).
And regarding capex equipment purchases, I've had my eye on a CNC router for more than a year.
Something that will route polycarbonate and thin sheet AL for immersion tank construction.
Made a corporate decision a while back that we're done buying equipment that has a programmed obsolescence (S(odd) and C1).
I'm sick and tired of replacing perfectly good equipment every 6 months - a year solely due to fixed a Vcore which caps the maximum efficiency of the gear.
Screw that.
And yeah I know I could rip apart miners, mod the hash boards (at least to some extent) and get better efficiency. That's a doable option on 1-5 machines but not on 50+.
It is my belief that even the venerable S1, had it been designed with a reasonable lifespan in mind, could be profitable to operate in today's environment given an adjustable Vcore and clock. But it wasn't and neither was any of the BM follow on products. I believe this was part of a designed marketing campaign to continue to sell "new" equipment. Smart practice for miner manufacturer's but not very good for the 200Th/s and down crowd. As such, we're committed to purchasing/building equipment that will "stand the test of time" versus a throw-away mentality.
GS's designs embody this thought process and consequently we will opt to buy their product(s) over a competitor's.
Phil - I am very curious to hear, when your S7's come in, whether one can adjust Vcore and if so by how much.
I just helped a friend to build his commercial cnc machine in the brooklyn navy yard it can do copper brass and aluminum.
They are costly even at the lower end commercial models. We did his for 12k. Much of the work was diy. I built the pc for it he had the mounting table and frame welded by local people in the brooklyn navy yard.
the pc boards, gearing, motors, spindles collects. you buy as a kit form. 1 set of percison collect is over 300 usd. alone. I was at his shop on fri. he is cutting some speaker boxes for me. I know him from a speaker building club.
when I get the s-7 I am going to try to find the lowest freq say 150 vs 300 (a guess at what the numbers will be)
then run at freq 150 hopefully giving me 200 watts and 800gh a blade.
I will then try to get 10.8 volts in stead of 12 volts to drive machine
