SIEG SC4 Electronic Lead Screw
For anyone unfamiliar, a lathe usually has a chain of gears linking the spindle/chuck to the lead screw that drives the carriage backwards and forwards along the bed. The gears can be changed to alter how far the carriage moves for each rotation of the spindle. For example, to cut the thread on an M6 screw, the gears would be setup so that the carriage moves 1mm for each rotation.

Playing a single note with SDL2
I have successfully avoided sound programming for all my programming life. Even when I tried making games, sound was always an afterthought. However, recently I got a new pair of headphones, and wondered: “what makes sound good?”, or “how much of the quality can be improved by hardware?”, and even “what is the structure of a sound file?”. If you’re looking for answers to all these questions — sorry, you are in the wrong place. I don’t have them (yet). But I can offer something equally fun: make your computer play a note by writing less than 100 lines of C code.

The team’s determination and keen eye meant that they could identify speakers that were still in working condition, despite being discarded by others.

[Old] I disconnected our smart oven, and maybe you should as well
I really don’t like the fact that my oven connects to China and Russia just to check if it has an internet connection. If that is the only thing it’s doing.
The support department isn’t very helpful as well, they have no clue what I’m talking about and refuse any help. Probably because there isn’t a hardware malfunction.
