I also forgot : you should at least try to go to a strictly chinese club. Those are huge clubs on various floors, with amazing lightning. The music is not so good, but the giiirls, hoo, the giiiirls ^^
Baby Face / G Club, are the only two I know.
Also, if you want to have a nice drink in the afternoon, go to the People's Square. There's a bar (I don't remember the name) with an arabic decoration, but it's on the middle of a pond full of coy fish. Really relaxing. The Urbanism museum is a must : the model of shanghai is just amazing.

In shanghai, you should try to go to the "fake market" (that's not the real name, but everybody knows it like that ^^)
I bought a nice 3-channel RC helicopter (quite a big one) for about 350 Yuan. The guy first asked me for 800. I could have gone lower but well, the exact same one is about 100 euros (1000 Yuan) in France ^^ I think you can find a lot of nice things hoping to be hacked.
You should also go around Beijing Dong Lu, that's a street with a lot of shops who sells about every mechanical items you'll need : linear actuators, ball bearings, etc... And there also is a place (I don't remember the name, but it's around Beijing Dong Lu too) dedicated to electronic components, some kind of small mall on 4 floors with about everything you'll need.

Have you ever been to china ? because you have to be careful about one thing when you talk with the people : sign language. For exemple, in china, 6 is done with the thumb and pinky extended, like the "aloha" sign of the surfers. Ten is a fist, One is the pinky extended, etc... It's really different, and the best way to bargain is to always have a calculator with you, so that you can write the price on the screen ^^

Also, you should go to the Bund. You'll be amazed by the sightseeing ^^

But the downside of it might be a simili-monopoly on the MCU market, and especially on the beginner/DIY market. I just hope that this will not increase the final price of the chips :/

I don't have any more infos.... That's why I'd like to have one under my soldering iron ^^

Hi
I guess you all saw the news about the 100.00 ex limited edition of Esquire Magazine featuring and E-ink display on the cover ^^
http://ryaninc.blogspot.com/2008/09/esquire-october-2008-e-ink-issue.html

My question : does someone living in the US can source me 2 or 3 exs and send them by mail to France ? please, help me, I really want to see how this is working (and keep one fully working unit for my collection ^^) I think it's 5.99$ each.

Cheers

Ok, Pro/E is a bit too complex for me ^^ I'll try that under solidworks. Thanks a lot.

Thanks trialex. What CAD software do you use ? If it's eagle, proteus or SolidWorks, I think I can do it myself, but in this case, I'd really like you to help me, never found the command for scattering objects ^^

(I guess I'll try with 3D Studio max, I think I saw an option I can use...)

Hi there.

I have a project which involve using 64n white leds scattered evenly across a disc. I'm planning on using 1206 SMD package leds, on a 10cm diameter disc, with a max7221 for controlling the leds. I have a little geometric problem though.
How can I find the right position for each led so that I can have a even distribution which will lead to an even illumination of the disc once I'll put the diffuser material on top of it ?

Is there a mathematical formula for dividing a circle in n squar-ish chunks of approximately equal area ?

Thanks for your help ^^

Hi there

I don't know if I mentionned it here earlier, but I'm working on opening a FabLab in France, and I'm searching for informations so that we can (with my team) apply for funds from the various administrations.
I found this video on youtube, but I need someone that can translate it for me (even a rough text file, just in order to see if it's worth using it).
It's about the FabLab DenHaag, so it's from netherlands... anyone can help ? ^^


Cheers and thanks

I have to go check the electronics shops in my area and test it myself, but I think a simple classic Oscilloscope Probe with the x1/x10 selector might just work fine. There was a link posted, not so long ago, on this forum I think, a japanese guy who used this kind of cheap probe and just changed the BNC connector with a simple Jack.

That seems to be just perfect ^^
I'll check about the probes (I don't want to burn my soundcard) but I just tested quickly Virtins MultiInstruments.... That's nice ^^
I think I'll buy some of their probes, or I'll try to modify some regular oscilloscope probes.
Thanks mem

Hi
I'm thinking about buying an oscilloscope, and I saw some USB probes, really cheap (like 50 euros on eBay).
I'm pretty sure those items are just a lost of money ^^

I just wanted to know if anyone have any good reference for cheap oscilloscopes, USB or not.
My goal is to be able to analyze signals encoded via NE5044 or LM1871 for RC toys transmission. If I can do more, it's ok ^^

Thanks

Hi there
I just put my blog online, and I'll use it (as the arduino and monome forum) to talk about my projects, especially the monome clone that i'm trying to build.
Feel free to visit and comment ^^

I usually keep the longer one to make jumper wires, but I just throw the shortest ones
