Diffused or Clear, Round or Rectangular? Quantity required? Good luck, Dave BTW 700nm seems more common.. Is that close enough???<p>[ Dece...

Re: SO8
Hi all, To remove SMD's with lots of legs, I found some stuff called Chip-Quick from Emulation Technologies. I think it may be available from DigiKey. It's an alloy with a super low melting point. Just a little dab will mix with the existing solder, and the joints stay liquid for quite some time. Ju...

Re: PCB Layout Software???
Hi Bob, I use the pay version of Eagle, but a quick check on their website shows that the freeware maximum board size is 4 X 3.2 inches and 2 SIGNAL layers max (Top and Bottom). You can have solder masks, silkscreens etc. for top and bottom, but they don't support multilayer boards. Freeware, with a...

Re: grounding straps
David, I understand your point about potential, and your reasoning that if the item is on the static mat that no electrostatic discharge will occur between yourself and the item, if you are connected to the mat (through said resistance). I'm not comfortable with having a static station at an unknown...

Re: grounding straps
James, If you are setting up a shack/shop, I would suggest sinking a copper rod into actual earth ground. We go 8 feet here at work, but 3-4 feet should suffice. Then we run #6 GA unshielded copper wire from it to a location under our benches where it can be "clipped" onto for our anti-sta...

Re: A/V Switcher Project
Dave, What specific Maxim part(s) are you looking for? I agree with Chris, Maxim is pretty
good about giving out samples. I have a box of various MAX parts. If it's in my "spare parts" box... consider it yours.
Good luck,
Dave

Re: Wireless Controler
Here's a simple idea. How about arranging it
so that the handle has to be screwed on tight
to complete the circuit. Just like some flashlights
operate. Low tech, but cheap and easy!
Have fun - "or else"!!!
Dave
Or do YOU want the remote to drive her nuts by turning it on/off???

Re: energy efficiency
Hi Dean,
I've seen the heating element on an electric stove glow (produce
light). Does that drop the percentage just a hair? Sorry... I just couldn't resist!!

Re: transistor pinout
Whew? My old 1985 RCA/SK book doesn't show any packages like that. If you have them, can you ohm them out?
I'll dig a little deeper thru the archives if needed.
