$2.99 for fucks sake! I've bought a few of them. Are they a Fluke? No, but I can buy 50 of them for the same price and they are accurate (against an HP bench meter) to about 2mV. Close enough 99.99% of the time in the field.
I'm a field service engineer and use this daily. Put one in your tool box, one in your trunk, one in your emergency kit, keep a few around to hand out to others when their batteries fail. Don't worry if you leave it up in the ceiling tile or drop it down a wall.. it's the price of a replacement battery.
I played with the 68HC11 back in the 90s, damn nice chip. Then a friend turned me on to Intel's 8052AH-BASIC and I don't think I ever burned another 68xx chip after that. Put a payphone into production using the 8052, not because it was cheaper (not by a very long shot) but because we were in a rush to market and an integer BASIC is so much faster to develop in than asm and converting the output to S-code.
A good amount of that Clearwire spectrum is used for tower-to-tower communications. One unique thing about Clearwire's system is they really don't like to pay for dedicated lines to towers. The normal setup is a few AggPOPs per market which feed, normally 10Gb fiber, to the market's TransPOP which often is colocated with the RDC (Regional Data Center). Each AggPOP will service one to several RF tower rings of three to eight towers, mostly via Dragonwave radios. Of course with tens of thousands of RF sites, there will be some one-offs, but the goal is to have as many tower sites serviced via the AggPOPs as feasible. The system from RF tower to TransPOP is PPB-TE Ethernet.
This allows them, as they are doing now, to lease some of that bandwidth to the towers to other carriers. Clearwire was always envisioned as a wholesaler.
Yes. They just forward biased a tunnel diode to cause quantum mechanical tunneling, which of course got through all the dirt and rock because they exhibit negative resistance.
On a side note, back in my teens, I would make $5 for swapping the top and third rows of buttons on a standard WECO 25xx phone so that they matched an adding machine. The ladies in the office loved it.
The best method I've seen for a data center is to have a patch bay in each rack going to a MDF (Main Distribution Frame.) Any inter-rack connection goes to the MDF and then to the destination rack. Google MRJ21
Here's the back side of a MDF for a Clearwire data center using MRJ21 connectors and cables.
If you need to figure out how to run your communications cables just ask the friendly people at Greybar. They have been dealing with this exact issue since 1869, yes, before the telephone. You have a Greybar near you, you've just never noticed. They open early so you can get your parts on your truck and too your job. Electrical, voice and data copper, to fiber. They have it in stock.
All that cool wire management stuff the telephone company has? They have it at Greybar. Need the racks and cable management to build a data center? They have it. Those special tools you need to put it together? They have them.
When I built a 100 rack data center I banned cable ties. Wax string is the way to make a clean data center, and one that won't tear your forearms when you go digging in the cable ladder. I also banned premade patch cables. Make them to length and terminate them yourself, cheaper that way. Go to any decent DC powered facility to see how it's done.
Audio? I was thinking more like the SB200. Puts out about half a gallon (500w), just enough to get you away from the barefoot blues. Keep it under the desk and your lower register 10 bits keep nice and toasty. Load it up and talk away, or ditty-bop if that's how you swing.

So is this why I can't find a torrent of the current season of Junior MasterChef Australia? Best damn food show in the world.
Touche'.
I already drive a '93 Saturn SL1, how much lower can I go?
And crows.

Why does Ghostery's home page have a "Friend me on Facebook" link?

(No, I just fucked up.)
Likely a small surface mount op-amp. Not a fun task to replace and requiring special & expensive tools. USB sound interface would be my suggestion.

The mic is fine. You're mic pre-amp is fried. Much harder to replace.

Or go to Greybar to get the real stuff.

But they'll have to heat it a bit for it to work in Fairbanks. ;)
You just need to run it in Landscape Mode.
