Descriptions of Electronic Payloads:

AltimeterOne Altimeter (Jolly Logic 29,500 foot altimeter)
Our simplest and most versatile altimeter. It is the only one listed here that doesn't require a separate payload bay to protect the altimeter. Just attach it to the bottom of the nose cone like a parachute, and poke some holes in the tube so it can sense the air pressure. Includes a rechargeable battery so you never have to worry about buying extra ones. Recharges on any computer USB port. Reports peak altitude only -- does not store flight data.

PerfectFlite APRA Altimeter
This altmeter has a high-sample rate from its barometer and simultaneous analysis, eliminating the need for a Mach Delay setting. No data is able to be downloaded to your computer.

PerfectFlite Pnut Altimeter
This altmeter has a high-sample rate from its barometer and simultaneous analysis, eliminating the need for a Mach Delay setting. Up to 31 flights worth of data - altitude (speed & acceleration are derived), temp, battery voltage - is recorded on this altmeter and is available to download to your computer.

PerfectFlite Stratologger Altimeter
This altmeter is used to deploy two parachutes out of the rocket. One at apogee (a small one), and another when the rocket is closer to the ground (a BIG parachute). This altmeter has a high-sample rate from its barometer and simultaneous analysis, eliminating the need for a Mach Delay setting. Up to 31 flights worth of data - altitude (speed & acceleration are derived), temp, battery voltage - is recorded on this altmeter and is available to download to your computer.

Entacore Programmable Dual-Deployment altimeter with data logging
Another barometric altimeter used to deploy two parachutes out of the rocket. One at apogee (a small one), and another when the rocket is closer to the ground (a BIG chute). This allows the rocket to come down close to the pad so you don't have to walk far. This dual-deployment altimeter also logs flight data, so you can look at the altitude versus time curve on your computer after the flight.

G-Wiz Flight Computers
This is more than just dual-deployment of parachutes. It can also be used to stage motors and set off outboard motors in cluster arrangements. It not only uses barometric sensors to find out how high the rocket is, it also uses accelerometers to find the rockets position and orientation. You can even add other sensors (temperature, spin rate, etc) and the computer will also log that data so you can look at it after the flight. It is a lot of horsepower that you may need for complex rocketry projects.

Altus Metrum GPS Tracker, Telemetry Transmitter, and Dual Deployment Payload
This one payload contains everything you might ever need in an electronics package. Not only does it do dual deployment, but it tracks the position of the rocket using GPS technology. It also includes a baro sensor and an accelerometer for extra data redundancy, plus it transmits all this data back down to the ground where you can display it real time on your computer. It can handle just about anything you want to accomplish in your super complex high-power rocketry project.

Staging Timer (PerfectFlite Mini-Timer)
This is a simple timer that will ignite a second motor in the rocket. Good for mid-power rockets where you are launching two stages. Can also be used for an inexpensive back-up control on other complex projects.

MicroBeacon Model Rocket Locator (Pratt Hobbies)
Fits in small rockets so that you can find them more easily. Emits a loud scream so that you can track it down by the noise. Great for getting your young sister to scram out of your room too.

Sonic Rocket Locator (Transolve BeepX)
This payload emits an ear-splitting siren after the flight is over. The noise helps you get a bearing on where the rocket landed so that you can retrieve it more easily.

Related Items and Optional Accessories That Go Great With Electronics:

Electronics Bays

These payload bays from Always Ready Rocketry fit most of the standard size Blue Tube, as well as tubes from LOC Precision. They are designed to hold the avionics or electronics that control the deployment of the parachutes in the rockets. It is a complete kit, all you have to do is supply the electronic payload to control when the ejection charges fire.

Ejection Canisters

These are small containers that hold the black powder ejection charge that is ignited by dual-deployment devices. The canisters are a one-time use item, as they melt from the heat of the ejection charge. Used only on high power rockets.

Tender Descender

This unique mechanism allows you to perform dual-deployment using a single parachute stowage compartment. It works by preventing the main chute from inflating, even though it has been ejected out of the rocket. At the right time (as determined by your dual-deployment electronics), it splits apart allowing the chute to fully inflate to bring the rocket down slowly and safely.

Quick Links

Use Quick Links to quickly attach and detach components of your rocket. Great for connecting parachute shroud lines and electronic or payload bays to shock cords and swivels or replacing lost quick links in your Tender Descender.

DVD: How To Mount Electronics In An E-bay

Looking for some help mounting your dual-deployment electronics in an e-bay? This DVD will walk you through the steps required to securely mount your electronics. It will help you gain the confidence to tackle complex rocket projects. Your friends, who thought you were all-thumbs, will be amazed at what you've accomplished on your own.
