Knowledge base Quark Common problems

Question #134
My metal case Quark feels hot when used. I also have a plastic one and it is not the same.
Answer

At the typical voltage 5V the Quark consumes around 50mA and thus 5V*50mA = 250mW heat is dissipated. In the little Quark case this is enough to feel a little warm and we have measured temperature increase of around 10C / 18F. It may feel even hotter if used with 8.4V. This is normal and has been taken into account in the electronic design.

Both plastic and metal case version are based on the same electronics and thus the same amount of heat is dissipated if the gyro is used at the same voltage. Any difference is purely due to human perception as we are all accustomed to the cold feel of metal which makes it easier to notice the heat.
