| | | | | Circuit diagram of Simple Isolated Analog-to-Digital converter This project was prompted by the need for a circuit to provide a galvanically-isolated measurement of battery voltage. Existing designs tend to be complicated, expensive or both, so a new approach was adopted, that keeps the circuitry simple, and relies on the timing capability of a CPU. I'm... | |

| | | I made the switch today to Let's Encrypt for all the certificates used by services hosted at siosm.fr. The official setup instructions are well written and simple to follow but not safe enough for my taste. The Let's Ecrypt page on the Arch Wiki also has most of the information required to get a working setup but does not care for security either. So here is a non root, confined setup for certbot, the official Let's Encrypt client. Although this was done on Arch Linux, this is probably generic enough to work on any systemd enabled distribution. | ||
