Cool idea with the "Light" version of the project.U.S. Water Rockets2 wrote:You obviously know your stuff! We were saving this for a later date, but since you brought it up, we are proud to give you a preview of the newest member of the ServoChron™ family: ServoChron™ Lite!Skymeat wrote:Great project! by the look of it you could pack the guts into a super tiny package if you pull the IC.
The concept behind this design is that you use the launchpad as a configuration tool and set up your parameters and then pop the chip and install it into the socket on your rocket. The whole design is made from a socket and a couple of LEDs and resistors that cost pennies apiece.
The whole controller can be assembled for under $2.00 and weighs less than 1 gram. This means that the ServoChron™ Lite is 1/20th the cost, 1/6th the weight, and 1/4 the size of commercially available products with similar functionality.
By the way, the MSP430 LaunchPad comes with not one, but TWO microcontrollers, so if you purchase a $4.30 launchpad, you have enough microcontrollers to make TWO of these ServoChron™ Lite systems!
Of course, the building of this system is a bit more involved, but can be simplified down to a air wired circuit that fits inside the footprint of the socket. About a dozen solder joints is all you need to build this setup.
We're finalizing some instructions on how best to power the MSP430 and will have schematics available shortly.
If you want to take the idea and adapt it for your own designs, feel free to do so. We want to encourage you to take the idea and expand upon it and spread the work around to help as many people as possible!
Any E.T.A. for the plans for this? I am pulling out Tim's old T-8 deploy design idea and trying to make it 100% reliable. For now in ground tests I will just mount the servo on long wires and remotely mount the launch pad board or leave it on the outside of the rocket and ground test everything, then when you have the new plans ready I will put it inside the T-8.
