166  Using Arduino / General Electronics / Re: My first PCB design with ATmega328P-PU, will this work? on: September 05, 2012, 02:32:24 pm
I emailed the Gerber files on the 24th of august.

I finally had the board made by Seeedstudio, the boards arrived yesterday. I soldered one today and did some testing. I attached 12 small servos and let them sweep. The 5V line is reasonably stable, it never goes under 4,85V. This is the design I sent of to Seeedstudio.
And here is a video of the board with 12 sweeping servos.
168  Using Arduino / Project Guidance / Re: Ethernet Arduino I2C LCD Conflict on: August 29, 2012, 10:52:37 am
You need to set the I2C address of the I2C LCD with something like this before void setup: LiquidCrystal_I2C lcd(0x27,16,2); You should find the I2C address in the datasheet of your LCD.

I have used an I2C display and ethernet shield without problems with an Arduino Duemilanove and Uno...
Here is a sketch with 2 I2C devices, SD card, temp sensors and an ethernet shield:

Gentoo GNU Linux for almost then 10 years.
170  Community / Bar Sport / Re: Your latest purchase on: August 23, 2012, 03:10:22 pm
Came back from a 4 week vacation and found these items:
10 PCB's from Seeedstudio, simple board for the ATmega1284P-PU
Finally received my Raspberry Pi with some accessories (USB power adapter, HDMI cable, HDMI-DVI converter).
Cheap USBasp v2.0 (bought on Ebay)

I love Atmel, they make the best micro controllers at the best price... Look at this
172  Using Arduino / Project Guidance / Re: NRF24L01 can not be initialized on: August 19, 2012, 09:05:50 am

When both were running I scanned with my phone for available Bluetooth Devices but nothing was found.

The nRF24L01 is not a bluetooth device.

RF24L01 modules are cheap. Take a look at this: But I think the library doesn't works with the attiny.
174  Using Arduino / Sensors / Re: DHT11 Sensor code issue on: July 15, 2012, 08:27:28 am
I just installed Arduino 1.0.1 and it didn't come with the DHT library. You can find it on the Arduino playground.
175  Using Arduino / Project Guidance / Re: Question about servo's and servo controllers. on: July 12, 2012, 03:58:08 pm
The Dagu quadbot uses only 2 DOF legs, so 8 servos in total. Absolutely no problem to control 8 servos with an Arduino Uno. Just make sure your battery is strong enough to power 8 servos.
176  Using Arduino / Motors, Mechanics, and Power / Re: TLE5206 5A Motordriver (Final Status) on: June 25, 2012, 02:22:21 pm
Do you really need the LM338T? Or are you using it because your power source has a to high voltage for the motor?
I need a 3A dc motor controller for an old RC car and was thinking about using the TLE5206.
177  Using Arduino / General Electronics / Re: Simplest/Slowest/Cheapest/(50meter range) to Interface to Arduino? on: June 22, 2012, 05:02:23 pm
I have a bunch of nRF24L01 modules, the small cheap ones don't have a range of 50 meters. More like 25-30 meters, with a clear line of sight. I have a couple of the more expensive (20$) version with amp and preamp. I've done some testing with those, it involved using my car... I can control my robot from 1,2km distance  smiley-twist
178  Using Arduino / Sensors / Re: NewPing (Ultrasonic) Library for HC-SR04, SRF05 and SRF06 sensors - v1.3 on: June 17, 2012, 09:50:46 am
Has anyone used this library in an obstacle avoiding robot sketch? I have a simple obstacle avoiding sketch that uses an old ultrasonic library, it works. But I wanted to try it with this library. Can I use "Distance = srf06.ping_cm();" in a sketch without the pingtimer/pingspeed code? Or do I have to use the "pingTimer" and "pingSpeed" like in the example? This makes it much harder to use in a sketch. I tried writing a function that returns the distance but I can't get it to work (I'm not much of a programmer).
179  Using Arduino / Project Guidance / Re: noob 1307 RTC issue help please on: June 16, 2012, 04:48:05 am
SDA and SCL on an Arduino Mega are on pin 20 and 21, they are not on the same pins as a Duemilanove or Uno.
180  Topics / Robotics / Re: Why can't hexapods walk faster? on: June 14, 2012, 03:39:27 pm
Buy the fastest servos and write efficient code. You need to find the most optimal "walking gait" for your hexapod depending on mechanical construction/servos. I'm quite sure the hexapod in the video can walk a lot faster then is shown in the video.
