the current quote button is so unintuitive that i actually made a new quote button the other night in photoshop! i didn't want to step on any toes or offend the author of the current quote button so i ended up not saving it.  :-[

Ooohh, post them up in the forum suggestions thread quick!!!  

Mowcius

hmm... i thought this was the forum suggestion sub-forum? is there a specific thread? i didn't search, but i skimmed the first few pages of suggestions and didn't see it.

speaking of the suggestion sub-forum... i think changing the name from "forum" to "Site Support" or "Site Complaints & Suggestions", etc. would keep the number of "how do i do ______" threads from appearing in here! my 2¢ fwiw.

quick reply box

quote and/or quick quote would be super too!

I am paying 5 bucks a month, and only getting a TB of bandwidth

at 30k a sketch, thats only 36,650,387 downloads!

The trouble is, the code probably was legit when someone put it in the playground, but then three versions of the IDE later there's some incompatibility and it doesn't work anymore.

ahhh... i see!

Code:

#define CPU atmega328
#define IDE 0.19

then the Arduino code pre-processor could squawk if the values didn't match with the currently selected board/CPU and IDE version.

Something for the Arduino 1.0 suggestions thread?

this seems like a brilliantly elegant solution! a fix of this sort would have a much further reach than just the playground as code posted outside of arduino.cc would also need to comply. 2 additional lines of code would be a small price to pay for instant, easily identifiable compatibility verification and would add to the overall quality of the platform!

again, just my 2¢ fwiw.

Like E-bay?

exactly! "is this code legit? or am i going to screwed out of the next 3 hours of my life?"  :-/

for a forum whose subject matter is so heavy based on code, the Insert Code function is pretty weak. a copy to clipboard button, a lift on character limits, or addition of file attachments would be VERY convenient! bandwidth is cheap! arduino files are small!

some sort of ranking system or users comments in the Playground would be nice! The playground looks like a very official establishment which leads one to believe that the code i contained within should work like the example sketches included with the ide. unfortunately, a lot of doesn't or needs a lot of tweaking and contains little to no comments. this can be very frustrating for a new user especially if the project contains additional or extensive hardware setups. user comments or a [ch10029][ch10029][ch10029][ch10025][ch10025] system could potentially save a ton of wasted hours and frustration.

my 2¢ fwiw.

i buy and sell stuff on rcgroups a lot. much simpler & cheaper than ebay!

+1 for a for-sale section! im sure we've all bought the wrong part at one time or another or have a surplus of a particular item that could be beneficial to other board members instead of sitting around collecting dust bunnies. its not like anyone goes looking for used dev boards on craig's list ya know.

that looks like a nice light. http://www.fobsun.com/9w12w-d138-downlights-p-202.html

• 1. It seems I just need replace the traditional lamps with LED down lights and not need to change the dimming system.

yes, if used with a dimmable power supply

• 2. How about the external power supply?

you will need a dimmable power supply of appropriate wattage.

• 3. CE is good.

indeed! fires are bad!

• 4.

• 5. We need 60°.

looks like they've got you covered. its interesting that they are projecting the inherent shape of the die and considering that a "feature".

check out http://www.dealextreme.com/products.dx/category.907 if you are on a budget or like to tinker. don't expect any CE certifications though

they have inches in italy??

but the OpAmp AN538 is for usage with 10volts, we are using 5v...? sometimes i wish i was native english, i probbably wouldn't ask these dumb questions...

also i'm not sure if my local shop has an AN538....

your english is quite good! where are you located?

i should have been more specific... there is no need for the opamp. you just need the RC filter. it wouldn't hurt to grab a few different values of small capacitors. they are cheap and handy to have on hand.

you can also vary the reference voltages to the lm39xx for matching signal to gain.
-sj

well, should have been busy with other things, but did this instead... this is how everything is wired for the LM3914 experiment..

add a resistor on the yellow line. i haven't figured out the formula yet, but you have to be careful you don't exceed the load capacity of the arduino output pin. ie: don't just grab resistors at random.

reason to build is, i wanted a customized controller, more specified to my needs.
I'm just taking it step by step. first i searched for all the right buttons, then faders (got 8 60mm ALPS faders since yesterday  ), found very heavy potmeters almost impossible to break... then finally i  will put it together in a mahogany box with a alluminium cut top case...

but that's a long way to go...

word. ergonomics is key! nothing commercially available has ever suited my needs 100%.

i've got loads and loads of vinyls 12", 10" and 7" just got tired of carrying it around! it's not nice to break your back carrying that stuff... also i can do some nice freaky stuff  with mp3's. so since about 3 years i break my back even more, bringing a laptop, soundcard, a usb-harddisk, some vinyls, some cd's....etc etc etc

i feel ya! i quit hauling vinyl around years ago as well! i was referring to actual mixing within software. i prefer a hardware mixer for multiple reasons; more i/o, consistent "feel" between sources, instant recovery from computer malfunctions, etc. i map traktor to 4 channels on a external soundcard (firewire 410) and bring into the mixer L&R x 2 channels. when used in this manner, traktor feels no different than your standard denon aside from it being 1000x more convenient!

mixing video is by far the most fun imo! its just a chore to do compared to traktor. my dj'ing wet dream is a media server hosting video files while controlling a front end with the latency of traktor. all video synced to pre-programmed dmx parameters. mmm...

so how would we convert the PWM signal? i think it should be converted to a saw right?

follow the schematic in that link. what you are doing is taking a variable length square wave and converting it to a variable height sin wave. (i think) anywho, its a low pass filter and it works.

i don't think pwm was what the chip designers had in mind when they first  designed it, but that doesn't make it "not right".  i think the "wrong format" is a more appropriate way to describe it. the pwm can be converted with equally acceptable results.
-sj

btw.... what are you building?  i plan on building a midi controller, but most likely just for navigating the file browser and trigging lighting scenes. i never cared much for mixing in software... just doesn't "feel" right to me.
