So, now I'm registered at yet another forum. Thought I should say hello before I start writing about my current project.
I'd say my interests are quite diverse, and covering science, motors, engineering, electronics, mechanics, hifi and of course music!
Listing all my previous projects would be a bit too much, but I thought I could mention a few of them.
When it comes to HiFi, my current setup is mostly home built. Actually everything but the speakers. For some reason, carpentry scares me (I'm more into working with metal). The amp is completely designed by me (chassis was brought from China buy an aquaintance) . Class A push-pull. Driver tubes; Siemens c3g, power tubes: KT88. All fixed bias, triode coupled. Sounds great! 35kg, ~2x25 watts. Not exactly the same power/mass-ratio as the PA-amp underneath it.
The turntable is my design. As you can see, the amp is not the only component that's completely finished. Mostly made out of MDF board (sand filled). Custom made bearing (oil lubricated brass bushing). Tone arm made from some kind of fiber tube. Bearings for the tone arm are recycled from a computer hard drive. Most people would probably not even try using a stepper motor to drive the platter, but with custom made drive electronics and a lot of fiddling with suspension and drive belt (cotton wire at the moment) I have gained great results.
The RIAA is not really my design, but came originally from Elliot Sound Products. Will build an all tube one when I get the time.
The DAC is based on a Weiliang DAC7 kit bought from Ebay. First I modified it, replacing the opamps with tubes but then I came up with another idea. Since the output from the DAC chip is actually balanced I could just bypass not only the buffer after it, but also the phase splitter in the power amp connecting it directly to the power tubes. Works like a charm!
One other project that has taken much of my time the last years is this: A huge pulse jet on skis. Quite interesting to get the most out of technology that is totally rubbish. More about that project here (in Swedish only unfortunately)
Well, I guess that's more than enough for a "short" introduction. As you might have noticed, I not too fond of just copying others work. Nothing wrong with getting influence from other people (I would not have registered here if I thought so), but sometimes I try to keep an open mind and try something new. Most of the times it ends in a complete failure/semi-failure, but sometimes the results are very pleasing!
What I like with these forums is that so many people devoted to one single subject/area are gathered in one place. And from what I have seen, there are some really talented guys in here.
I will start a thread about my new project soon. Just need to prepare some first
