Wire Wrapper Tool

Image
This is a beautiful and inexpensive tool; a rare mechanical hand tool with precise tolerances. To attach fine wires, such as wiring up LEDs into circuits, wire wrap makes soldering unnecessary. Strip about 3/8 inch on the end of a wire, thread the exposed wire up one of two incredibly tiny slots in the end of the wirewrap tool, put the other tiny slot of the wirewrap tool around the wire it is to be connected to, like the anode or cathode of an LED, then twirl the wirewrap tool in your fingers, leaving a tiny tight spiral of wire wrapped around the connection.

US Cable Operators Trim Subscriber Losses in Q3—But OTT and the Economy Still Exact a Toll- Subscriber numbers to decline overall for 2012—the ninth straight year of contraction

US Cable Operators Trim Subscriber Losses in Q3—But OTT and the Economy Still Exact a Toll- Subscriber numbers to decline overall for 2012—the ninth straight year of contraction: By Erik Brannon

The good news for U.S. cable operators in 2012 is that they posted their best third-quarter performance in terms of video subscribers in at least two years.
The bad news is that the operators still lost nearly half a million subscribers during the period as competition from IPTV services like FiOS and U-verse continued to diminish the cable companies’ opportunity to add new households to their customer rolls. Even worse for the U.S. cable operators, their net subscriber losses for the full year of 2012 are expected to exceed those in 2011, according to an IHS Screen Digest Television Intelligence Report from information and analytics provider IHS.

DRAM Losses Widen in the Third Quarter for Besieged Suppliers- Weak PC demand, coupled with soft commodity DRAM pricing, pulls down the market

DRAM Losses Widen in the Third Quarter for Besieged Suppliers- Weak PC demand, coupled with soft commodity DRAM pricing, pulls down the market: By Dee Robinson

The market for dynamic random access memory (DRAM) took another beating in the third quarter, as downward pressure on pricing caused by a weak PC market dragged down industry profitability for all DRAM players, according to an IHS iSuppli DRAM Dynamics market brief from information and analytics provider IHS.
The cash balance in the third quarter for the industry, excluding Samsung—the only one to post positive profit margins during the period—fell to $4.5 billion, down 13.5 percent from $5.2 billion in the second quarter. Operating losses widened to $671.5 million from $348.4 million, after the industry had managed to trim the deficit from -$1.1 billion in the first quarter.
Overall, industry operating profit margins decreased to -10.7 percent on third-quarter revenue of $6.4 billion, down sequentially from -5.1 percent, in an …

Tinkercad:


If you want to introduce a kid (or yourself!) to CAD (computer aided design), Tinkercad is by far the easiest and most fun way to begin. Today I mentioned to my 10-year-old that our CNC machine would soon be up and running. He asked what a CNC could do, and I said one example would be to carve a battlefield out of stiff foam for Warhammer figures.
That got his attention . He wanted to know how to tell the CNC what to do. I explained a bit about CAD, and showed him Tinkercad, giving the example of one cube that you could stretch and change.
Then I got busy with something else and left him to figure out Tinkercad himself. I came back an hour later and the below is what he’d designed. A ten-year-old. No training. One hour.


The green stuff we’re going to CNC out of a sheet of stiff foam. The rest we’ll probably 3D print on the Makerbot. It will take a weekend, but this could be our first 100% digital craft project.
This is an example of what I talk about in Makers: manufacturing …
