Some people don't think about what they are seeing, and aesthetic appreciation isn't a rational process. If a schematic or a pcb just looks like one that worked well in the past, you are going to like it better than one that looks like something that didn't. As "facts" go, this has to be one of the less useful ones. -- Bill Sloman, Sydney

If a schematic or a pcb just looks like one that worked well in the past, you are going to like it better than one that looks like something that didn't. As "facts" go, this has to be one of the less useful ones.I find dollar signs to be very aesthetic. That is what the boards produce, so the ultimate perspective on the work. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209

They make Corvettes from epoxy-glass. We did get one batch of end plates with anodize in the countersunk holes, in defiance of the notes on the drawing. We'll have to touch up with a countersink to clean them up, a mild nuisance. I wonder if there is a kind of flathead screw that has groves or teeth on the bevels to scrape through the anoddize. I'd google but I don't know what to call that. Maybe our Boss laser could do it, clean out the anodize on the countersinks.

Today was interesting, I killed my Chinese satellite receiver box few days ago in the storm likely did draw too much power when I moved the dish against the storm we had. had replaced the original current limited 12 V wallwart with a more powerful one.. my fault... It would still move the dish but always to the wrong angle.. Dish motor on PC sat card OK,, So dish positioner OK. Bought the thing for about 30$ or so on ebay years ago, 1080 progressive HD, >900 free TV channels, many satellites.. Lots like these now for double that price locally... Anyways opened it, and could not find any defective parts Very nice multilayer board, very dense, tuner, several switchmode converters... no partnumers readable.. Almost gave up.. what could it be? lots of work to enter all my satellites and stations in a new one.. then I had an idea, nothing to lose... switched from manual angle definitions to USALS and low and behold, now I have even more stations Probably a bit flipped in the firmware, but in USALS it calculates position from your current (GPS) location each time you select a sat, And look how nice it is made,: http://panteltje.com/pub/hd_sat_reciever_front_IXIMG_0862.JPG http://panteltje.com/pub/hd_sat_receiver_backpanel_IXIMG_0863.JPG http://panteltje.com/pub/hd_sat_receiver_backpanel_IXIMG_0864.JPG http://panteltje.com/pub/hd_sat_receiver_inside_IXIMG_0865.JPG that is a 500 MHz processor under that little heatsink (ball grid array) The buttons and display are on a separate PCBs conencted with flex cable. You can open it by removing 2 screws in the back thin metal housing just slides backward... nice cinch connectors screwed against the back LNB input fixed to tuner module that is fixed to the PCB can take a hit and 30$ !!!! There is a LOT to learn from this, I had it all apart and was amazed by the PCB layout My hat off to the designer of that box. Value for money .. value for many... many versions :-) https://www.ebay.com/itm/354190172519
