PicPost: Headphones Amplifier
Since a long time i wanted to check out DIY Amplifier design and building (see http://ideas.kanojo.de/ for a rough timeline oO). As a first-tryer i opted for a Headphones amp as a friend is a real HighEnd-Headphones fanatic and well ... it's simpler and cheaper - you don't need large capacitors, big heatsinks, uber-powersupplies ... all nice n tiny.
The Amplifier itself is a TexasInstruments TPA1517NE Class-AB Amplifier that is driven at a voltage of 18V (to be able to supply a reasonable signal for high-impedance (600ohms) headphones. The Schematic is almost the application note except for enlarged output capacitors to lower the cutoff frequency of the output-filter. Both powersupply and amp reside on on PCB.
The casing is made from 15mm Multiplex, routered at the edges. The volume-control knob is also routered from the same 15mm MPX material. The edges are routered along with 45*
Buuut, as this is a picpost, here they come:

Yay for another cool HiFi Project - a mini-monitor using the MarkAudio "cheapo Series", CHR-70 which benifits from the design- and production experience MarkAudio has from it's larger brothers but is made with budget considerations in mind - so in short it's a modern, well-designed and manufactured "mid-budget" speaker which performs just great! The cases are Teak-veneered MDF, the design is a GHP ("Geschlossen mit HochPass" -> Closed with HighPass Cap) design from a HiFi-Forum (german board) member which was influenced by the "GHP" concept of a german HiFi-magazine...

Alto II – DIY HiFi getting more serious!
After i managed to write up the guide/documentation for the cheapo-tenöre yesterday i today want to post more of DIY speaker sweetness - a "Alto II (Variation)" - again a self-developed speaker by a HiFi-Forum member. It is - as you can see - a large floorstander with two Visaton chassis and the second speaker i ever built.
This is - by the way - not going to be a guide, as there are people who can do this far better than me with those more advanced speakers. Time comes, maybe sometime i'll develop nice speakers myself 
At least thats the plan. But for a picture-documentation - please read on!
“HiFi” on the cheaps, DIY Speakers for few euros…
As a friend and myself built me a pair of quite nice - not to say wowzie - speakers for music production and DJing a few years ago i was now eager to try myself. To get the basic idea of craftsmenship and woodworking i started not by developing the speakers myself - as it was done by my friend for me back then - but go for a well known design by a guy from the german Hifi-Forum: The TenÖre Transmissionline Broadband-speaker. The name comes from german dialect/puns and roughly means "10-euro thingy". A perfect object to train the techniques needed for more complicated work...
