196  Using Arduino / Motors, Mechanics, and Power / Re: WIll this Battery work with my 4 servos and my Arduino UNO board? on: May 13, 2012, 05:09:34 am

Also, does anyone know the type of convertor this guy is using on the end of his battery? I think I will need something like this.

(this is the battery used in the above pic, but I thought it was kind of on the low side power wise,

Thanks, Mike

Ha, that's my picture smiley I got the connector from Tayda electronics -> I use the 500mAh battery to power my "Arduino remote control" ->

I looked on digikey and they can ship to Belgium
Price Break   Unit Price   Extended Price
1           2.88000    2.88
25           1.80920    45.23
100           1.60800    160.80

prices are in USD

They have a Belgian website but they only sell to registered companies. You need to provide a VAT number if you want to buy from them.

Since I'm Belgian I can't buy from places like Mouser, Digikey or RS. I've ordered electronic parts from Tayda electronics in Thailand a couple of times. They sell the ATmega 328P-PU for 3,5$. That's cheap enough for me smiley

When I use a bare ATmega328 on a breadboard I use this drawing to see the pins:
Very handy because it has the Atmel and Arduino pin numbers on it.

Together with Rodrigo Castro an Arduino 1.0 update was made for - -

The code should work under 0.22, 0,23 and 1.0

As always comments and remarks are welcome, in this thread.

I think there is a typo in the example sketch on the playground.
#if ARDUINO >= 100
#include <EthernetUdp.h>        // New from IDE 1.0
#include <UDP.h>

UDP.h should be Udp.h
At least on my system:
sketch_apr26a.cpp:31:17: error: UDP.h: No such file or directory
I'm still using version 0023, my gentoo installation and 1.0 don't play nice. I should do something about that and switch to 1.0  smiley-red

Oh, and thanks for the sketch and libraries.

I bought some, at this price it's worth the risk.

What voltage is your Lipo? I use a 2 cell 7,4V Lipo for my Rover/robot, I monitor the battery voltage with a voltage divider consisting of 2 10K resistors.

How are you powering the Mega when it's not connected to USB?
204  Community / Bar Sport / Re: Your latest purchase on: April 16, 2012, 03:09:33 pm
Received 30$ of components from Tayda electronics last week. A bunch of voltage regulators, leds, transistors, mosfets, switches and 2 ATmega 328P-PU's. Will try to put a bootloader on them later this week.

I also use Linux. They each have their irritating idiosyncrasies.

Each operating system today (including recent Ubuntu releases) seem to follow the philosophy of "let's treat the user as a moron and give him/her a wizard to do what we think they need to do".

If you fall foul of what they think you want to do "hey ... I didn't want my file saved automatically!" then you are in trouble.

For that reason I use a source based GNU Linux distribution, Gentoo. I've been using Gentoo for almost 10 years and still love it. It's certainly not for everyone and I have spent a lot of time fine tuning it to my taste.
But I'll be honest, getting Arduino 1.0 to work on it took even me as an experienced user many hours.
206  International / Nederlands / Re: arduino en robotics onderdelen - favo shops in BE en NL ? on: April 15, 2012, 03:09:08 pm
Ik koop zowat alles op ebay, meestal van Chinese verkopers. Nog geen pech gehad, nochtans de laatste maanden tientallen onderdelen gekocht. Duurt soms een tijdje maar meestal komt het hier binnen de 2 weken aan.
Voor electronica onderdelen bestel ik regelmatig bij Tayda electronics in Thailand. Daar verkopen ze nu ook de ATmega 328P-PU, wel zonder bootloader. Heb er vorige week 2 ontvangen, kosten 3,5$ per stuk.

I've also bought a L298n board on ebay. I got mine to work ->

I've used GNU Linux exclusively on my home workstation for the last 10 years. Is there any difference between Arduino on Windows or Linux? Should be the same experience? I just feel more at home in a Linux environment.
209  Using Arduino / Networking, Protocols, and Devices / Re: which rf module to use? on: April 14, 2012, 12:47:47 pm
Have a look at Xbee modules, well supported by the Arduino community.
210  Community / Bar Sport / Re: What would your dream arduino be? on: April 14, 2012, 12:37:04 pm
You are going to produce microcontrollers? That's a big investment  smiley-money Or are you going to produce Arduino like boards with ATmega microcontrollers? Maybe a board with Xbee and a H-brigde is an idea, would be popular for robots.
