Even if it were rather limited in how one can configure that state machine, one could likely get it set on new interesting applications. Just imagine what one could do with a reconfigurable state machine handling variables in the hundreds of bits. Though, I wouldn’t be the slightest surprised if the actual “mining” part is a large state machine built to do its one job of mining with no reconfigurability to speak of. Though, the exact same thing can be said about video encoders, some specialty audio effects chips, etc, but these are at least still useful for their original application, while a crypto mining ASIC isn’t useful for its intended application when it has gotten “old”.Ī few math functions dedicated to very large numbers, probably a bit of memory, maybe even a core for administrating the work. I don’t know of any other chip that is as “useless” as an antiquated mining ASIC. Though, I can see how that would interfere with mining performance, after all, an ASIC for mining only really has 1 job, and that is to be a waste of resources by the end of the year. Wouldn’t it be nice if crypto mining ASICs would have some features in them to make them useful for “anything” when they get obsolete as far as crypto goes. Posted in clock hacks Tagged ASIC, bitcoin, blockchain, hash, mining, mqtt, network time protocol, ntp, oven, temperature Post navigation This seems like a bit of a long way around to solve this problem, but since the mining dongles are basically obsolete now - we talked about them way back in 2013 - it has a nice hacky feeling to it that we appreciate. He does say that he has plans to let the miners do useful work at some point, not so much for profit but to at least help out the network a bit. Alas, heat is all they produce at the moment - just has them working on the same hash over and over. Heat is added to the chamber thanks to seven Block Erupter ASIC miner dongles, which are turned on by a Python script when a microcontroller sends an MQTT message that the temperature has dropped below the setpoint.Įach dongle produces about 2.5 Watts of heat when it’s working, making them pretty effective heaters. , having heard that thermal stability keeps NTP servers happy, used a picnic cooler as an environmental chamber for his Pi- and GPS-based NTP rig.

This is an example of the lengths to which Network Time Protocol aficionados will go in search of slightly better performance from their NTP servers. It’s all figurative, of course, but in the case of this NTP server heater powered by Bitcoin mining dongles, money actually does become time. They say time is money, but if that’s true, money must also be time.
