The series that hooked me | (especially since I do a lot of work around broadcast software) | was the one about the technology of television. | | Give yourself a gift in the new year of watching through his | backlog, you will not be disappointed! | mistercow wrote: | If you're into the electromechanical stuff, his jukebox | dissection videos are also great. | larusso wrote: | I follow his videos for years. I enjoy is quibbles with being | in the US and constantly getting comments what is supposedly | saner in Europe ;) (I'm from Europe). I started when his | content was mainly about video/audio tech etc. But I also very | much enjoy his videos from the last two years which show | everyday or old time Technology. | starkparker wrote: | Of all things I think I liked his two on dishwashers the most. | Did not expect that, but it just utterly demystified something, | and it was refreshing to see someone go through a process, come | to a conclusion, _admit error_, and go into thorough detail | explaining it. | peetabix wrote: | Yeah, the ones on dishwashers doubled as a PSA. | abjr wrote: | That video literally changed how I use (and clean) my | dishwasher! | quijoteuniv wrote: | Wait for it ... | zyxin wrote: | Those schematics look surprisingly similar to ladder logic. I | always thought that ladder logic for programming PLCs makes | absolutely no sense compared to a proper programming language, | but now I see that it does make quite a lot of sense if you're | trying to get electrical engineers who used to design actual | physical logic circuits into programming PLCs. | Bloating wrote: | Not so much the EEs, but the techs who are | troubleshooting/tweaking in the field | cricalix wrote: | Tim Hunkin did a video on PLCs and the like, and talks about | precisely that, as memory serves. His videos are also a | treasure. | finnh wrote: | Nice! My family has a "Spirit of 76", inherited from my father- | in-law who bought it new. It's always fun to open the machine up | and trace through all of the connections. | | About ten years ago we hired a pair of local guys to replace some | worn-out bits - nothing major, just bumpers and light bulbs. They | were exactly what you would hope for in such a duo: their initial | evaluation step was just one guy playing (the guy with long | hair), while the other guy (the guy with glasses) watched | closely. During this phase they communicated in grunts and | monosyllables, a tight code borne of years of shared experience | between them. | | [update: The Spirit of 76 gameplay is nearly identical to the | Aztec shown in the vid] | a-dub wrote: | once had the pleasure of learning a bunch about these machines | from the operator of the pacific pinball museum (then called the | lucky juju) in alameda, ca about 20 years ago at a class at an | early proto-makerspace in west oakland called the crucible. | | the scoring motors and relay logic were fascinating, but if you | want to see even more interesting electromechanical logic check | out the turing bombe and collosus rebuilds at bletchley park. | that em logic was credited with shaving years off of wwii and | came many decades before. ___________________________________________________________________ (page generated 2023-12-31 23:00 UTC)
