After you have the correct voltage at a certain point, does the current that a DMM would measure at that point have to equal the current that a sensor uses? for example, a sensor i'm using needs 2.5V and says it draws something around 1mA. when i…
I know a similar question has been asked, but I tried doing what it said and i ended up gettin smoke from a resistor. luckily i didn't hook up the sensor to it. i tried using a voltage divider using the method…
"it's the same price to get the two sensors that are on the 5DoF imu separately so i think i might do that. then i guess i'll get the Gyro Breakout Board - ADXRS300 - 300 degree/sec to measure yaw. it's description says it's made to measure yaw so i…"
"i kinda wanted to get the sensors individually in case i ever decided to replace a specifc one though. do you think i'd be a lot better off buying a "package"?
also, i really wanted 6DoF. i'm not too worried about the cost although i don't wanna…"

so i think i'm finally to the point where i can actually try to put together an imu. i'm using a parallax propeller to make it. i plan on using one of these guys to build it on. i'm looking for suggestions as to what sensors i should use to make a 6…
"so is this how it works? i've attached an image because it's easier than trying to explain what i'm thinking.my_understanding.jpg"
ok, so i got one of the memsic dual-axis accelerometers. the picture that comes with it shows the chip with the x and y axes, as well as tilt about those axes. there is a pin for Xout and Yout. what exactly are the values that it is outputting? does…
"so then does that mean gyros measure rotation? or do they also measure translation? are there cheap gyros that are usable for learning with? the cheapest one i found is $74.95

is a piezo gyro made with accelerometers or is it somehow different?accelerometers measure translation and not rotation, correct?which is more commonly used, a two-axis or three-axis accelerometer?also, which is a good one to use (for testing /…
"here's the specs for a microcontroller that i'm familiar with. does this look like it'd be comparable to the others that you guys use?

12.what about the dimensions of the ailerons we may require for high stable flight dynamics?
ailerons are usually designed to be 20% of the chord length. again, there's equations for calculating the total surface area…"

"Got cha. So then do you recommend any micro-controllers that may be a better choice? I'm considering sticking with the c8051 as I'm already familiar with it and it seems to have all the capabilities I'd need.
Also, how is the Ardunio platform? I…"

Hi all,I'm somewhat new to building UAVs. I've done some research at school on methods of control applied to UAVs so I'm not completely new however I've never actually tried to make one fly. I was just wondering why everyone uses BASIC Stamp…
