YOUYUE 858D+ hotair station — BLDC Fan-speed mod

I’ve finally forced myself to layout a small board. It’s been far too long anyway. It consists of these building blocks: reference voltage, comparator, RC low-pass, gain. There are better methods for the job, e.g. using a digital one-shot to … Continue reading

“Easy” remote-admin — take 2

In my previous post I described a method for a boot-activated remote-admin option for my parents’ computer. On 2nd thought, it is not always a good idea to rely on changing system-wide configurations (such as sshd_config, firewall…) In this post … Continue reading
