Can a Antminer S3 still mine any pool in 2024? For educational use

[aksuited]

I am not looking to be profitable, but I am trying to get some antminer S3 to mine successfully in any pool for educational use by students.    When I tried a few old S3 in multiple pools they all connected but never hased anything..   just all disgaurds

I tried btc.com, antminer and a few other btc/bth pools and they never hash after connecting

[BitMaxz]

Can you able to access the dashboard?
Would you mind sharing the kernel logs here so that we can review what caused this problem?

What I would like you to try is to try to run the unit with one hashboard and test them one by one.

[aksuited]

Yes thank you

Here was my current kernal log with 3 pools:

Would you mind trying to factory reset the unit by holding the reset/ip report button for 5 seconds then release if successful then setup the unit and test it again.

If still didn't work I found someone who has similar logs and he fixed the issue by flashing the unit again check the link below

If still does not work check this troubleshooting guide below

I am not looking to be profitable, but I am trying to get some antminer S3 to mine successfully in any pool for educational use by students.    When I tried a few old S3 in multiple pools they all connected but never hased anything..   just all disgaurds

I tried btc.com, antminer and a few other btc/bth pools and they never hash after connecting

An Antminer S3 does roughly 0.5 terahash, the modern miners do 200th~, with that said, 0.5TH is good enough to register a few shares on most pools since the pool difficulty is far less than the network's, just give it some time and it should hit some shares and report some hashrate.

I would try cksolo pool since that would display the shares your miner submitted, most pools don't do that and would just show you the hashrate which is a different representation of how many shares you submitted at x difficulty but still not so helpful in your situation.

It's also worth mentioning that most pools have a minimum payout (0.005 BTC for most large pools), which means this S3 is probably never going to hit the required payout if it's mining alone.
