History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.

Bits and bobs
Pictures taken during exercising my hobby (electronics) and building/disassembling amplifiers and/or upgrading a record player tonearm and pre-amplifier. Anyway, a text was needed, to describe this lot, and here it is (the text and the lot, enjoy the pictures :)).
Protecting Inputs in Digital Electronics

this was my dad's first camera, hopefully he'll teach me how to use it. it needs a new battery, and they don't sell the one it needs anymore. but i really hope i can find one that'll be suitable.
I found this lovely Konica in a local charity shop for £1.99. They had a big box of old cameras but I managed to restrain myself.
I love the chunky black and orange look of this camera. It's solid and heavy compared to modern cameras.
Here's a photo from the first film.

My son holding the camera.
Flagship model of Fuji X series. My husband wrote the review in Japanese, I took the photos of the camera, in March.

The latter part
The Phottix Odin wireless TTL flash trigger has now been officially released.
Note that this photo shows a pre-release version of the Odin - the silk-screen labeling on the release version is slightly different.
Key features of the Odin include:
-much better range than Canon ST-E2 or Canon 580EX as master flash trigger (100m +)
-ETTL support for remote flashes
-even in manual mode, flash power output can be set from the Odin transmitter control unit
-can adjust zoom of remote flashes from Odin's TCU
-high-speed sync up to 1/8000 seconds
-second curtain flash sync
-uses commonly available AA batteries
-compatibility with Phottix Strato 4-in-1 trigger and the Strato II Multi trigger
For more info, read my review of the Odin.
strobist info: 580EX II at top right into reflective brolly, 580EX at top left into reflective brolly, both triggered by Canon ST-E2
A 120-film camera with a rudimentary auto-exposure system, dating from c.1961. This is (a later version of) the second version of the Fujipet [Camera-wiki], the first version having a round, conical viewfinder perched on the top, and exposure setting by a lever with weather symbols setting the aperture. The first auto-exposure version had a red with white letters EE badge and no sensitivity knob beside the lens. This newer version has a selenium-cell controlled trap-needle ("EE") exposure system setting the aperture, and a self-cocking shutter.
This one still seems to work; covering the meter cell prevents it firing. There's a two-position knob beside the lens which looks like it sets colour or black-and-white, presumably changing the aperture range, as the shutter is marked as 1/60s below the lens.
WEEK 20.2 – “Conns”truction Update
While the previous pictures were taken from Hudgins Road (which actually dead-ends right past that interstate-facing entrance I just showed you), this one is taken from the familiar perch of the former Super K's parking lot. Signs were going up at a fast pace, and I expect the main Conn's sign may well be on the building at this point. Judging by the design of similar new Conn's stores, I'm guessing “mattresses” is the word being prepped for installation on the bottom right in this shot.

These places are public so these photos are too, but just as I tell where they came from, I'd appreciate if you'd say who :)

This is what a notebook computer looks like in 2013. It's more commonly referred to as a notebook than a laptop. The first computer that I could remember was an Intel 386 back in the late 80's in Hong Kong. I've seen the explosion of the Internet along with the rise and fall of the phone line modems peaking at 56k speeds. I remember 13 years ago when AMD broke the 1GHz barrier with their Athlon. There was a time when CPU's could just be passively cooled. The emergence of wireless Ethernet was at times painful, but welcomed. This little machine with a diagonal of 11.6" no thicker than an inch is definitely more powerful than anything that I've cobbled together with parts. Quite nice to have so much computing power in a rather small package. The next technology improvement that I'm really looking forward to is for the widespread adoption of 300dpi LCD screens.
