Re: ADNS2620 Mouse Sensor Evaluation Board

Did you fix the lens to the underside of the evaluation board? It won't work without it.

Re: how many magnetometer axes ??

I don't think you can find the pitch angle with a magnetometer, I'm pretty sure you need a 3-axis accelerometer to do that.

Re: Monitoring sensors without USB on Arduino

The questions make sense, but why do you want to do this? You can power the Arduino from a 9V battery and still connect USB to see the sensor values. However, to answer your question...I'm pretty sure there aren't any RS232 level signals on the board. Arduino uses the FTDI chip to translate the TTL ...

Re: RC Car Controlled by Arduino and Xbox360 Controller

Excellent work! A few suggestions... Since you're new, I don't know if you know about Arduino Shields. Basically they can be inserted directly on top of the Arduino to give access to different modules. SparkFun has a shield called the ArduMoto, which actually uses the L298. You might want to check i...

Re: Designing the Ultimate IMU

Any idea what this new IMU will be called? I'd actually like to call it 'Ultimate IMU,' but I'm sure we'd get slammed for that. Any good ideas? How will it compare with your 9DoF Razor IMU? Similar in that it will have 9 degrees of freedom; a different gyro will be used and it will have an ARM core...

Designing the Ultimate IMU

Hi everyone, SparkFun is updating the 6DOF v4. Over the last couple years we have added several IMU boards to our stock, but it's become apparent that we need a 'high end' device (at least we think we do...). There have been many threads on the forum about IMU's and people preferences and problems w...

Re: Sparkfun Portable Rotary Phone Charging Problem

Is the battery 'completely' dead when you plug the charger in? If the battery voltage is too low the charger circuit on the rotary board will go into a slow charge mode and the LED won't behave as you might expect. Leave it plugged in for a while (maybe up to an hour or so) and see if the red LED co...

Re: two Button Pad SPIs, no button feedback

You could try attaching the feedback wire from the output pin to the MISO pin labeled on the sides of the board, rather than the 'input' pin. The last poster is correct; the pin labeled 'input' only works on a USB button pad controller, not the SPI one.

Re: ADXL345 breakout & self-test

Hello,

Have you verified that you can read the DEVID register to validate your SPI command protocol? Also have you checked to make sure that the resolution, range and bandwidth rate are set appropriately for the self test?

Re: Compass Module with Tilt Compensation for Arduino?

The HMC6343 is not as fast as the HMC5843. The HMC5843 can update at a maximum of 50 Hz while the 6343 is only capable of 10 Hz. What are you trying to do with the compass heading? Might the slower data rate still fit your application? These sensors use a communication protocol called I2C; it's a tw...

Re: Compass Module with Tilt Compensation for Arduino?

Hello, This could be interfaced to an Arduino: http://www.sparkfun.com/commerce/product_info.php?products_id=8656 It's very pricey, but tilt compensation doesn't come cheap. If you're feeling amibitious you could get a triple axis magneto sensor without tilt compensation (like this one: http://www.s...

Hi,

Congratulations on making it this far!

Check out Gold Phoenix for your PCB; they can assemble circuit boards for you as well but I'm not sure what the quality is like. Their prices are great, and their turn-around time is less than a week (when it's not Chinese New Years).

Interesting. We don't have one but I'll pass the recommendation on to our marketing department. We're always looking for ways to better market ourselves.
