I have to replace the chain every 1500 km. I replace the chain multiple times, store the old chains and then do a second run (the rationale is that putting a new chain on a used drivetrain does not work, so I need to wear them gradually). A

There are ACME clients written in Python 2 or even pure shell -- should work even on very old systems (but not older than ~2010, you need openssl with TLS1.2 support). I personally prefer them even on current systems, as I don't really

Can someone explain whether it is actually illegal (e.g. the person who will cut the lenses and fit them to frames will be charged by some kind of practicing without a license), or they just don't do it? For the record, in the Czech Re

SIM800L costs $2. It supports GSM (AT commands - dialing, SMSs etc.) and GPRS (both PPP and a direct TCP connection to a hostname and port). Regarding USB dongles, I've been running Huawei E3131 with RPi. I needed to put +5V directly o

I think you are underestimating the number of decays. You have 5.5 moles of the substance, that is, 5.5 * 6e23 atoms. The half-life of Cf-252 is 2.6 years. You therefore need at least 5.5 * 6e23/2.6/365/24/3600/2 =
