Cerwin Vega breaker problem solved



I cleaned the potentiometers and circuit breakers with contact cleaner. Where the 'pots' were difficult to turn and sticking before, they now turn smoothly. The breaker contacts do not work perfectly, but a few presses of the reset button fix the problem.
The binding posts spring action is rough due, I think, to oxidation over decades. I've binding posts left over from the Valencia project. I may find a way to install new 5-way binding posts.

Someone on eBay was selling a Cerwin Vega U123 crossover panel for $15.95.
Two were available. I offered $26 for both. The seller accepted my offer. Those will be here in a couple of days.

I ran across a webpage mentioning speaker re-foam and re-cone. I read more on the subject then examined my speakers.

The Cerwin Vegas could use a re-foam, though their functioning is not affected.
I ordered a re-foam kit for them. One of the Altec Lansing Valencia woofers has a small hole in the cone. There's not much too the hole. Small, about the size a pencil tip might make, a couple of millimeters in diameter with fuzzy edges, more like a tear than puncture. I may order a re-cone kit for that woofer. The re-foam kit for the Cerwin Vega 12" woofers is $24.98 for both woofers. The re-cone kit for one Altec Lansing 15" woofer is $65.

UPDATE: I got the breakers and pots working and the foam surrounds are still fully functional so I'm keeping the spare crossover panels and foam surround kits until, and if, I need them.

Drive rack, ventilation and wiring.

 My drives have a new rack to hold them. Hot glue and square wood dowels provided the materials with which to build the rack. I used zip ties and a small computer fan attached to the end of the rack to provide cooling air ventilation for the drives. This will increase the lifetime of the drives. Previously the were stacked on top of each other and became noticeably warm during use. The wiring really was bad. Too many cables/wires held together with zip ties. I added a surge protected outlet strip of a newer, more sophisticated design. I rearranged the system wiring to minimize the number of outlet strips and the disarrayed wires. Two strips were screwed to the wall. One was removed. The circular strip was moved from the entertainment center to a work table beside the other two strips and combined with them to supply all devices attached to the system. The strip removed replaced the circular strip in the entertainment system.  Overall, the current setup works better. Both syste...

Philips Hue lights Updated

 Philips Hue lights are known for the ability to program brightness, saturation, and hue using software. Most people use one or more cellphone apps to control their Hue lights. I've a history in computrer science and electronic technology and engineering, so took this up as a new interest. WiFi control of light bulbs' colors has interested me ever since I read aboout the topic some years ago. There happened to be seven Hue bulbs available from one eBay seller and for a reaosnable fee, approximately $20. A bridge device is used to communicate with the bulbs, so I waited for a good deal on eBay and got one. Philips has evolved a developer community and resources for those who want to explore the possibilities in lamp light control. The user joins the communnity and gets a temporary API key, formerly referred to as a 'username', good for one session. Then a browser or app, can be used to send commands to the bulbs. There are other avenues of communication. Python libraries...

Jellyfin media server

 The owner of Emby has blocked my using the WebOS access method of using Emby. I discovered the method and posted on the product's forum. That software is no longer my media server and has been removed from my computers. I replaced Emby with Jellyfin. Jellyfin is the evolved Emby open sourced. Emby was originally open source (and free) but was privatized and monetized by the creator. Many considered that move unethical.  The last open source version became the basis for Jellyfin,  easily competitive with Emby and almost, if not equally, well known. I've been using Jellyfin for about a year, perhaps more. The software has issues but is in constant development but is very useful in the current state, version 10.8.5.
