Explanation:
Phase 1 and phase 2 kits are on the lower left.
Starting at the upper left:

Grounding mat with wrist strap. Doesn’t actually have a connector TO ground, you’ll note, but does keep you and the workpiece at the same potential, so better than nothing. Now you appreciate the little chain that drags on the ground under the carts and chairs in some labs.

Some people and their environment and wardrobe choices generate more electrostatic potential than others. I know a guy who used to lead with his car keys to the latch seat on the door jamb, whenever he went through a doorway at the office. One key would arc to the bare-metal plate the door latches on. He drew arcs that made audible "pop!" sounds if he didn’t offer a low-impedance path, and the arcs hurt. Could have had something to do with polyester suits. I prefer cotton.

The mat can’t hurt, might help. If the workpiece’s grounded cord is plugged in, use an alligator clip haywire to connect chassis ground to the mat. Or touch the chassis ground with one hand while working. Or connect the mat to ground at a grounded outlet- the North American 3 wire receptacle ground connection take a standard "Banana" jack. (A forthright Canadian friend uses the word "jill" in place of "receptacle"… the counterpart to a "jack". Suit yourself)

Ethernet (RJ-45) to USB adapter. More than two connectors and a wire, there’s Ethernet transmitter / receiver hardware in the body of it, and USB receiver / transmitter hardware too. Just like you’d expect, these have their own MAC and you may have to make that known (depending on how your network runs). Sadly, I haven’t yet seen a PXE boot setup that accepts the external adapter’s MAC. But I have over-written the adapter’s default to have the adapter take the place of a failing-but-not-completely-broken built-in NIC…
Note ROM disk with drivers.

Partially-unbent paper-clip, size large. For resetting things with recessed reset buttons, forcing CD/DVD drives to eject, etc. Its on a badge-clip and attaches to the lanyard with the bootable USB stick. Save the last one you made and you don’t have to find another paper clip when time is of the essence…

Small tube of thermal putty. Better quality heat-sink-and-fan assemblies come with a dab already in place, and it will squish and flow when heated. If you’re reusing a heat-sink when upgrading the processor on something, you’ll need your own supply. It does dry out, so put the cap on after cleaning the surfaces. Don’t buy the big, economy, size, unless you really use it frequently. I don’t like to let an open tube go more than 6 months.

Non-conductive ruler. Wood or plastic. A metal edge on a wooden ruler is OK, but an all metal ruler is unnecessary trouble.

Grounding strap – wrist band to aligator clip, use with mat or separately, see discussion at top.

Pocket-size volt-ohm-(amp)-meter, aka VOM. Cheap. Something to read what you expect to be +/- 5V, 120 VAC, 240 or 208 VAC, +/- 12, 3V lithium cells for CMOS memory, etc. Built-in leads don’t fall out or break off. Some alligator and/or "ball clip" jumper wires will help if you need to secure one or both ends. Ammeter functions in these are usually too few mA to bother with, but if you use it, get some replacement fuses, its a "when", not "if", situation.

"Magic" tape dispenser. For mending or sealing paper and cardboard. The "magic" 3M tape can be written on with ballpoint pen, vastly superior to shiny tape.

Large multi-bit screwdriver, with Phillips, regular, Torx and socket ends. For unusual jobs, where it is worth having the right tool for the fastener. You can’t buy an assortment of ‘bits’ without getting all the regular blade and Phillips sizes in any event. I prefer a dedicated handle and a bit that doesn’t come off, but I don’t have 1.3 meters of wall space to hang them all on.

Phase 4 exists, it includes a small, sharp, knife, coffee cup and coaster, cup or can for pens, pencils, plastic flatware, skinny tools; duct-tape, vinyl tape for color-coding, extension cords, a Brother or similar label maker, zip-lock polyethylene bags, nickel-plated anti-static bags, boxes and bins for organizing stuff, extra monitors, keyboards and mice. Broom, dust-pan, small-but-powerful vacuum cleaner (Mighty-mite from a garage sale, or similar). Speakers for your radio / computer / phone audio when acceptable. I don’t favor headphones in the lab, may people do. A water bottle or large plastic cup.

There are also consumables: tie wraps, facial tissues for blowing your nose and cleaning up surfaces, paper towels / napkins, light cardboard tags to attach to stuff that has a story. Blank CD/DVD media. A notebook.

1.28.11 – The importance of a good mouse is key for most digital artists, photographers, and designers. Logitech has served me well since as far back as I can even remember. The last brand before Logitech I honestly remember in my hands was an IBM one that came with the first computer my family ever got. I grew up playing around with commercial computers that had black and green screens and required line commands but this computer was a "personal computer", something all nerds lusted for. This was when color computer screens were considered some huge leap in computer technology. "Imagine the power required to produce all those colors!"

The clunky, large white mouse seemed so amazing at the time. Dust would collect in the tracks in a matter of weeks, making you loose control of your pointer. This then forced you to take the ball out and clean each little roller sensor. The cord would knock things over on your desk at times and you had 2 inputs (1 on a mac).

How far we have come. This mouse is ergonomically shaped to form to the human hand in a comfortable position. It wirelessly sends signals to the computer using a laser sensor that can work on relatively any surface and has 10 inputs. Just think what the future holds for us tech-heads if this kind of progress can be made with something as simple as a mouse in such a short amount of time.

The days of the mouse are numbered though. Touch screens and highly advanced motion sensors will become the new age of computer interfaces. What next? Full integration? Ok, I won’t get too carried away. Happy friday everyone.

1.27.11 – I have been wanting to shoot this for a long time now. This giant book was built to allow local graffiti artists to have their way with it. It always reminds me of what in high-school we called "The Rock." It was what I always supposed was originally a giant 4-foot-tall boulder from the mountains. The tradition was to have each class come and paint over the previous lower or upper classes markings. We would have friendly battles back and forth month to month.

Like an old giant tree, this huge blob had hundreds of layers from multiple generations (including my mother). I volunteered as an on-call firefighter for a couple year in high-school and one night we got called out to the station for a fire at the school. Turns out someone had covered in gas and lit the thing on fire. The flames were taller then the people on the scene. No damage was caused, but we always assumed it was a rival football team from the hills. The Rock still stands today with fresh coats of paint from new generations of students.

gaming 6 button mouse

gaming 6 button mouse

This is pretty cool. Nobody ever thinks to get a good mouse do they?
I wanted the exrtra buttons for gaming where you have to throw grenades flashbangs etc,
I play counterstrike online sometimes and am rubbish at it.
It is very sensitive and a slight movement moves it totally off screen.
It does take some getting used to if you use a normal crappy mouse. They cost less than £5 on ebay delivered to your door.
It works on win 7 but I havent tested all the buttons fully yet.
It isnt an ultra gaming mouse but is good for the price I reckon and a huge improvement over a standard mouse.
The dust on it is ash I’m a smoker.
A wired mouse is proven to be a lot faster than a wireless one.
here if youre interested
www.ebay.co.uk/itm/ADJUSTABLE-1600-DPI-USB-WIRED-OPTICAL-…
The ad says fully adjustable but there is no driver cd with it so maybe you adjust in windows? It’s MUCH faster than a normal mouse straight of the box plug in and play. You just get the mouse in a box
