I just got done meeting with a rep today. Check out these super cool LED's. 1000 lumens!!! or thousands of lumens.
http://www.laminaceramics.com/products.html<p>Certainly overkill for a reading lamp, perhaps even for a car headlight, but most interesting.<p>Ron

Re: TV Lift - Limit Switches & Controller Relays
Rather than a micro switch, you could use a reed switch and a magnet.<p>http://www.hamlin.com/index.aspx?tabindex=3&tabid=7<p>You could also use a hall effect sensor.<p>Ron

Re: Sending data on AC supply lines
If you have lots of data http://www.intellon.com/ is a good source. Their parts are pretty easy to deal with, although the firmware has a significant learning curve. The other thing is you may be able to get some good interface ideas from their data sheets.<p>Ron

Re: help - need encapsulant?
Emerson and Cuming is the outfit I usually turn to for encapsulants. They have a wide range of materials, and are liberal with samples.<p>http://www.emersoncuming.com/<p>Thanks

Re: Using transparencys for pcbs?
The developer is usually sodium carbonate. Its pretty inert stuff, and as long as you aren't buying a ton of it, I don't think you get hit with the hazmat fees. It might be worth trying washing soda from your grocery store, as it is a hydrated form of sodium carbonate.<p>Once you do photo, it is unl...

Re: Component sources
Interesting, it looks very similar to the early days of partminer. Its too bad they couldn't make it fly back in 99. (Good for you though). Now www.freetradezone.com is a whole lot more combersome to use. I think you may be onto something, but I wonder why partminer went away from the methods you pr...

Re: Las Vegas Test Specification
Actually it does not seems to be statisically based. Part of it may be the Chinese to English translation, but I'm not sure.<p>I did get a blast reading the responses though... eg how long it runs until it craps out <p>Ron

Re: Electronics Assembly at Home
I use 4-5 home assemblers to build my prototypes. However they bill me by the hour, as with prototypes, its pretty hard to put a firm figure on the price. There are a few outfits that do low volume production (under 1K units/year this way), but they are rare. While home assembly is cheap, its way to...

Las Vegas Test Specification
I've searched all over to find the test requirements for the Las Vegas Test spec. My Asian supplier of pager vibrator motors for one of my products calls out a Las Vegas test. I'd like to know what it is, so I can write up an appropriate qualification spec. For some reason, my supplier is unable to ...

Re: Large LED display
Flip disks are cool, but they do not survive a shot gun very well. Its a big problem with road signs in rural areas. I'm not sure if they have a shot gun test spec, but I do know the utility equipment suppliers do. Multiple LED signs with steel barrels do much better, as typically only a few LED's g...

Re: Using transparencys for pcbs?
I use great white transparencies for making the negatives. I can get reliable results at 12/12. Less than that, I create a 2X print, and then have a print shop reduce it and put the image on film.<p>Not sure what you are refering to heat wise. The UV exposure bulbs do not get more than a few degree ...

Re: help with x-10
Building your own X10 interface is a real chore. The timing issues and zero crossing can be tricky, but the safety aspects are perhaps the worst. Remember you have hundreds of amps of peak current capability. A minor circuit error or part failure results in a charred mess. Been there done that. You ...

Qprox switches
Has anyone used these. They are sort of hidden in the digikey book. The idea is really cool, and it said one could use wood... Thats got me thinking, of what I don't know yet, but a wooden switch panel is interesting.<p>Ron

Re: Ru on circuits
Actually thats a subset.... There is a huge book, otherwise known as the UL yellow book that has all of the code and standard numbers and their assignments... Its a must have for systems integrators, and electrical inspectors.<p>Ron
