I haven't published them yet... I have 4 or 5 variations kicking around. We decided to build up a set of plain-jane boxes with a circular port 1st just to make sure we weren't out to lunch on the sonics. They woun' have the finese in the bass (at least i believe) of the final with high profile slot ports, but should give a good idea.... internal gross volume 0.483 litres with a 1" ID port 48mm long -- stuff lightly. if you want to get playing. Modded FE127 in stock.

In the back of my mind is an even smaller variation using the FF85K,

Btw, I recieved the modules from siliconsolar. Absolutely fantastic. 8 volts 250mA in a 141.35x141.35 mm (measured, a little bigger than the spec sheet says) epoxy encased pre-soldered package with direct solder pads on the back.

The finish is great with a 3.45 mm thickness on the middle slopping towards the edges to 1.95 mm. They also have a higher working angle than any I've tried before. Can't wait to start blasting my own solarpowered DIY boomblaster.

Is there a reason you didn't choose these-

panels, they would seem to be a better deal?

Yes, the space where I wanted them to fit into was 2 142x284 mm squares exactly. But yes, on the next revision I'd probably use other sized modules. Besides the weren't available 2 weeks ago when I ordered mine.

After a few inquiries, siliconsolar admitted to have messed up the specs for some of their OEM parts after I pointed out that some of the specs listed were physically impossible to achive even at 100% conversion effeciency. They're correcting it.

They have erroneously put in mA were it should read mW. Those that you linked to are only 350mW @ 9V, not 350mA @ 9V.

The webpage is still riddled with mistakes though, so inquire to get exact specs before purchase.

Yesterday I drove past Roskilde, had to think about you Saturnus Been on a holiday to Sweden, met the man behind 41hz.com.... As I expected he's quite a nice guy....

He's doing pretty well, surrounded by women helping him on the job

Helped him out with the last bits on AMP10 basic to get it released, very nice sounding little amp.

I'm working on a mini waterproof stereo active speaker myself. Here's a pic:

I live in Copenhagen, you could've stopped by me to have a look at (or listen to) my boombox. Send me an e-mail next time you pass by these northern outskirts of the civilized world.

Yeah, I saw the amp10basic being announced, hopefully that also means Jan has found some coils that could be used in a future amp9basic.

Lovely cool lil' thing you got there. Macaroni? Hmm... how about Maca(r)phony? Or even MyCarPhony.

I have plans for a similar one, just with two solid plastic balls both cut with a V shape with a 60 degree angle, and a small space between the two cuts. Then glued together at one cut, and the speaker mounted in the other cut.

I sure will, but I was with friends and one audio related visit was all they could handle... But 'I'll be back!'

I can't check the uH value for TA2022 and TAA4100A right now I somehow can't connect to 41hz.com.... But current-wise the inductors should work for AMP9.

Mycarphony? Some of my friends made fun of it the same way before saying 'hello?' in one end ...No, it doesn't sound that good in a car. I know because my car amp (audiodigit MC4x100,much like AMP9) had fried itself on the way up (it was covered with someone's blanket) So I had to use the 'macaroni'. Than met Jan and got myself another AMP9, than the whole content of my car was stolen. They smashed the back window and stole all my clothes, my amp, batterychargers, batteries, discman, bikestuff and all my dirty laundry Lucky I still had the macaroni under my seat....and an MP3 player....

Thanks to Jan I had a new trunk door from the trashyard within an hour for just 100EUR

How's a solid plastic ball gonna work as an enclosure?

Very sorry to hear your experience from Stockholm. I always liked the city very much and have several friends there that I visit as often as I can, in fact I'm going there in 2 weeks time. Hope your insurance covers the loses, and you know, sometimes it's good to have a forced wardrobe change. (I too once had a lot of clothes stolen).

We had a beach party on saturday with my boombox, several friends, and BBQ. It was great.

You'll have to excuse my lack of Paint-skills but I've tried to illustrate the principle of the double ball speaker here. The balls aren't really balls, they're roughly 200mm diameter round trawl floaters used for keeping the top part of a fishing trawl up. They're made of roughly 4mm thick very hard plastic with a hole through the middle. The idea is to cut it so the solid hole is cut out.
