1  Using Arduino / Motors, Mechanics, and Power / Capacitor as battery to power motor on: March 18, 2013, 09:30:00 am
Hi all,

 taking a leaf from the powertoys (paper aeroplane), i am researching if it is possible to build a capacitor charged circuit to power the motor (http://dx.com/p/wltoys-v911-tail-motor-main-motor-for-rc-helicopter-silver-123236).

 it will be two parts: 1) charging circuit to charge the capacitor and 2) for the charged capacitor to run the motor.

 pls advise me. thanks
2  Using Arduino / Project Guidance / Bluetooth headset with arduino on: February 22, 2013, 10:58:42 am
hi all,

i just wondering if it is possible to mimic a bluetooth headset using an arduino and bluetooth module? i believe i need some headphone and mic. any comments? thanks
3  Using Arduino / Networking, Protocols, and Devices / Bluetooth communication issue on: January 15, 2013, 12:02:53 pm
Hi all,

 Pls advise if can. i had bought two bluetooth JY MCU http://dx.com/p/jy-mcu-arduino-bluetooth-wireless-serial-port-module-104299
and http://dx.com/p/bluetooth-master-uart-board-communication-module-blue-152175 (master) and tried to get both of them to link up. i had ensured they have the same name and pin number. But i still unable to get them link up.

 in addition i had additional pin STATE/KEY and EN on the master uart board which i had no idea how to use and if it is important.

 Pls advise me. Thanks
4  Using Arduino / Networking, Protocols, and Devices / Re: How to get the JY-MCU bt board to work on: January 12, 2013, 10:22:54 am
i have tried to connect the RX and [tx] pins of the jy mcu to the TX and [rx] pin of the Arduino UNO3 respectively,  but my simple AT command (enter through the Serial monitor of Arduino IDE) have no response. I only managed to get the "goodnite mr moon" to work. any ideas? i seriously doubt my connection is wrong but it still baffled me.

i learn that this is a slave one, but does it meant by soldering the pin 34 and pull high will make it a master (with the changes in role)?

** just curious for the sketch, does it work with Uno3? understood need to initialize the softwareSerial but that applies to other versions of arduino rather than uno3. uno3 has pin 0 and pin 1 as rx and tx pins

or using molex connector?
6  Using Arduino / General Electronics / Re: Organizing wires for arduino to Perfboard on: December 29, 2012, 10:26:58 pm
i used the SIP header with individual strand of wire but with the crossing of breadboard jumper wires between the perfboard to the arduino, maybe i lack the insight to use them in the correct way. thanks for your suggestion.

btw can show any pict or links to hope to utilize the ribbon wire to connect from the perfboard to the arduino? that will help visualizing the outcome better.

perhaps i can place align all the headers in a single file, and solder the headers end to the individual pins on the chips and use the rainbow wire to connect all of them to the arduino.

Hi all,

Any good way to organize wires from arduino to Perfboard. i had connected my arduino to my Perfboard (which holds a 293d motor driver) and with all the wires between them, it look so untidy and troubleshooting a nightmare..any good tips for reducing or organizing the wires? many thanks

regards

You're going to need at minimum a full-blown desktop PC, probably a server tower, with some really high-end components in order to process that many video streams on the fly like that.

that is true if we are thinking of using digital image manipulation techniques. E.g. manipulating the color of the water see link http://news.softpedia.com/news/How-Can-a-Magnet-Change-the-Color-of-a-Liquid-59251.shtml

but that is real advance and out of my league... smiley

adaptive camo refers to changing of colours to blend with the environment...like a chameleon. i came across this during my googling where some one is trying to build similar stuff for his uav..see link http://diydrones.com/forum/topics/adaptive-camouflage but i think he was hindered in the quest as he having problem with the weight as he is using LED. Perhaps there is other way to do it... smiley
10  Using Arduino / Project Guidance / Re: Arduino Question on: December 29, 2012, 09:04:57 pm
Is the Arduino computer software only allow you to program any of the robot kits or can you make it remote control?

it would be helpful if you can rephrase your question   smiley
11  Using Arduino / Project Guidance / Possible:? Adaptive camouflage? on: December 29, 2012, 11:30:12 am
Good day

Just for discussion, do you think it is possible to use Arduino to build adaptive camouflage? any brainstorming ideas?
Thanks for reading and responding to this post  smiley
12  Topics / Robotics / Re: which lipo battery to have for robot on: December 27, 2012, 01:12:51 pm
thanks for your prompt and helpful response. but am curious, isn't the voltage regulator is in built with the charger? how to determine whether i need the 7+v type or 11+v type? i will be powering up my 1) motor driver 2) arduino board 3) sensors (IR + ultrasonic + IR(RYB)) 4) communication (bluetooth). do i need to take note of the amperes? thanks
13  Topics / Robotics / which lipo battery to have for robot on: December 27, 2012, 10:46:38 am
hi all,

  i am new to lipo battery and am using AA batteries for my 1st robot. May i check what is the type of lipo battery i should buy and the charger as well? thanks

14  Using Arduino / Project Guidance / Re: Remote control Fan on: December 26, 2012, 10:52:11 am
thanks, i believe the relay is a "power up" middleware which helps TTL 5 v arduino output to interface with higher power circuit.

Any idea how to rewire the fan control unit to interface with the arduino?

thanks, i hope it is a feasible project..smiley-grin

Wonder is it possible to add a wireless control to the fan
I don't believe the Arduino has a fan. None of mine do, anyway.

Making an Arduino control a fan, turning it off or on, is easy. Setting the speed may or may not be, depending on the fan.

Using an Android to push switches on the Arduino is possible. Though using your finger is just as easy.

Perhaps you need to explain your project a little better.

perhaps i had not been clear in my writings,
1) Interfacing Arduino to control a stand fan. Original fan control unit is of push buttons. Use the arduino to replace the fan control unit to control the different oscillations speed.
2) Use Android program to communicate to the Arduino wireless. Android app will act like a remote control.

wish to get some ideas what components are required? is it possible to modify the fan control unit ?
