Yeah I’m thinking a shield with photoresistors, a decent speaker, a couple of RCA line outs. maybe a joy stick controller or a touch pad like a lot of synths have now, maybe even some sort of DAC, a small amp circuit, and midi jacks oh and a mic too. It would be really cool if there was a memory for a sample too!
would you need memory, or have a line in line out capability so you could use it as a pass through device?
Well both 
It would be nice to have a little mem for a stand alone device, but also be cool to pass though into a analog in (yes it works, I’ve tried it) and the out through a PWM pin and you could apply effects to the signal.
Another idea for an open source project would be (what i posted in the Open Source Projects area) is a pwm driven speed controller for 3 - 20v motors at varying amps.
I think that coming up with an open source option for this would be great since good speed controllers are pretty expensive and often have way more stuff that what DIY’rs and hobbyists really need.
I am working on that right now, but i am just in the study phase right now.
Hi madworm,
Yes, is an interesting project, I was looking at it. I was thinking that maybe we could use the client made for other logic analyzer: sump.org/projects/analyzer/
The client of this FPGA-based logic analyzer is java, so can run in pretty much any OS, and can understand I2C and SPI. We would just need to change the communication protocol with the hardware, I guess. BTW, that’s a quite remarkable tool to make also, the Spartan-3E Starter Kit is 149 usd and it would be useful for other projects too (you can just make it become the logic analyzer when you need it).
Back to the simpler 4mhz/4ch logic analyzer, it could probably be implemented on the arduino. A few days ago I played with this: timothytwillman.com/?page_id=155
Would be interesting to write some UI for this arduino logic analyzer, or use the other java UI i mentioned before (inheriting the ability to decode I2C and SPI).
Also take a look at this one that is 6 channels and uses the atmega168 and GUI in Processing:
uchobby.com/index.php/2008/0 … -analyzer/
What would also be useful is a development board for a Microchip PIC microcontroller, like the PIC18F4550.
A very good example for this kind of project is the CUI ( create.ucsb.edu/~dano/CUI/ )
Anyone seen this one ?
code.google.com/p/cec-arduino/
code.google.com/p/cec-arduino/wi … lInterface
Its a HDMI CEC interface for the arduino, might be nice to have a HDMI CEC shield, ideally with a HDMI female connector 
It enables one to command and control all HDMI connected devices, e.g. ask a TV what channel its viewing, set its volume, or tell the blu-ray speler to start playing video with the audio output via the amplifier.

I’d love to get a FPGA development board, at least just a breakout board for one of the most common IC (from Xilinx or Altera) and a suitable USB programmer, something like tinyurl.com/2526ou (or better and cheaper 
)
I realize that some FPGA experience could now be made with Open Workbench Logic Sniffer, but I’d prefer something more specific / dedicated.
Best regards.

GPS tracker with GSM
“The Tracker responds to text message commands, detects motion, and sends you its exact position”, useful for robbery situations.
Here is Open GPS Tracker project link: opengpstracker.org/
Would be great if seeed studio depot developed with a board with gps/gsm module instead of using a mobile phone. There is a small gsm/gps module from Telit, but maybe we could find cheaper 
Another ideia, is to have this built-in on a PCI board on laptops, if it is stolen, we could message “LOCATION” to get the gps coordinates of the laptop. Why PCI ? just to steal energy from laptop and a easy way to be attached.
Hi!
I recently designed a AR Envelope Generator for modular synthesizers which I want to provide kits for people who don’t want to etch their own pcbs or build it on strip boards. A friend told me about your site and your price is surely the lowest I’ve seen on the web. Since your prices are for 2 layer pcbs I’m even thinking about redoing the layout for a pcb where you can also put potentiometers, LEDs and jacks onto the board for easier assembling.
Ok but anyway, here’s my question: I’m working with open source software KiCad and when I ask it for a drill file it gives me a file which ends with *.drl, is that ok for you? Do you have any experience with KiCad Gerber files? And how is this thing running with the free kit? If this works out nicely, I have a lot of ideas for future open source projects.
Check out my stuff here: http://zaunerelektronik.net, I’m talking about the Zauner Quad AR Generator.
Thanks for you answer!
Hi guys!
I working at Pinguino project:
pinguino.cc/
“Pinguino is an easy-to-make Arduino-like board based on 8-bit or 32-bit ©Microchip PIC Microcontrollers with built-in USB module.
Pinguino is also an Integrated Development Environement (IDE) which gives everyone the ability to make easily an application without spending hours learning pragma, configuration bit, command line compiler, etc. The IDE is compatible with Arduino’s Language and Libraries. It’s available on LINUX, WINDOWS and MAC OS X.”
We finishing support for PIC32, and I think Seeedstudio can help us, making boards and accessories.
I have some related posts on my blog: fazzi.eng.br
Another question, how be a partner and reseller of Seeedstudio?
ClockTHREE!
We would love it if Seeedstudio hosted ClockTHREE, a open source, multi-color word clock.
Project Page: wyolum.com/clock3/
Instructions: sites.google.com/site/clockthree … structions
Source Code and Design Files: code.google.com/p/clockthree/
There are a couple of sub-projects
ClockTHREEhjr – a single color version of ClockTHREE (cheaper than ClockTHREE)
I2SD – an pre-alpha SD card on and I2C bus.
Please contact wyojustin@gmail.com for more information.

the new generation of stepper drivers:
allegromicro.com/en/Corporat … 982_88.asp
with the A4988 you can drive a stepper of 35V 2A per phase max! in full-, half-, quarter-, eighth and sixteenth step mode!
much nicer than the easydriver and can be made at rougly the same cost…
the link for the wiki including eagle files:
(i have no idea if these eagle files meet all the criteria in the datasheet but it looks prety oke)
I’d like to see capacitor ESR meter, it doesn’t have to be ultra precise, just something simple like the existing Capacitance Meter Kit. Unfortunately I don’t have experience with any particular kit yet, I’m just looking for one so I thought I’d suggest it. I believe more people would use it too, it’s basic tool for repairs but I don’t see many of them on the market right now (or they are profesional and too expensive).
Hi,
We developed a Pachube (pachube.com) compatible energy monitor using Arduino and an Energy Meter Shield from Olimex Chile (olimex.cl/product_info.php?c … cts_id=600)
This meter reads instant voltage, current and power. Also measures the accumulated energy consumption in kWh. With the energy meter shield you can upload your energy consumption data to the web so you be able to analize it and change usage habits, all this at low cost and using Arduino!!
Instructions and source code is available in our website.
Check a screenshot of the Energy Meter monitoring data

If you have any question about our project contact us at www.olimex.cl
bye!

I think programmable dummy load to test load your Charger or generator…
a kit with an led matrix, and some led’s and a rainbowduino would be pretty cool. that or the some controllers for an led array, and then a matrix.
I know a lot of people that want to make these but the hassle of having to collect everything you need from multiple sources is a downer for them.
Hello everybody. And I would just recommend starting learning programming with Python programming. But precisely to understand what programming is in general, without specific plans of using it as a professional programmer. This is because you need the python homework help anyway. As for me, this is the best option to understand how everything works. And then you can already decide which programming language will be next. Do you agree?
