About

Please click Share or Tweet above and spread the word! Thank you!

Screamy is a durable lost UAV alarm. It beeps loudly when you lose your aircraft. Whether it's an R/C plane, a quadcopter, or a UAV, Screamy helps you find them all!

Why You Want One

  • It's loud. 1/8 mile range! That's 660 feet / 200 m!
  • It's durable. We dropped it, froze it and baked it. It'll survive even the hardest of crashes.
  • It's small. Weighs 9 grams and is 1" x 1" x 3/8".
  • It's configurable. We are releasing the software as open source under a Creative Commons Attribution-Share Alike license. It's free. You can even get it now if you want!

REWARDS

Rewards Table
Rewards Table

Screamy

The basic reward is one Screamy. You'll get one Screamy for somewhere between $30 to $60, depending on how quickly you place your pledge. Do it quick! 

You can add on additional Screamys for $49 each (retail is $75). The bigger the pledge, the more you save! 

Kickoff Flight

Shortly after the campaign's over, we will write each contributor's name on a banner. We will then fly the banner behind a small UAV (equipped with a Screamy, of course!) and video the whole thing. The more you contribute the larger your name will be on the banner!

Let's see how long we can make this banner!

Shirts

Here are the T-Shirts in our collection:

"It's Dangerous To Go Alone" ($25)
"It's Dangerous To Go Alone" ($25)
"When All Other Lights Go Out" ($30)
"When All Other Lights Go Out" ($30)

What is the Plural of Screamy?

No one knows. We can't agree between ourselves! Help us! The person who claims this reward will decide the proper name of multiple copies of Screamy.

Add-Ons

Here's how add-ons work:

  • Pledge for at least one Screamy
  • Each additional $49 rewards you with one more Screamy. That's 33% off of retail!
  • If you selected the Really Early Bird or Early Bird special, you may opt to simply double your pledge to get one more Screamy.
  • Add $25 for the "It's Dangerous To Go Alone" T-shirt
  • Add $30 for the "When All Other Lights Go Out" T-shirt
  • Add $7 for a USB charging cable

In the backer survey, sent out at the end of the the campaign, we will confirm with you the add-ons you wanted.

TECHNICAL DETAILS

How to Use

A slide switch turns on Screamy. It beeps once at start up to tell you it is on. Then, it listens for a triggering condition.

Screamy can be triggered in 4 ways:

  • loss of signal from the R/C transmitter, detected by the lack of a PWM signal on the SERVO pin
  • low system battery voltage (VBATT). Screamy auto-detects what low voltage is based on the battery voltage. If no battery is connected to start with, then this check is ignored.
  • A low-level signal on GPIO.  A relay that grounds the GPIO pin alarm will do.
  • A timer defined in the code. Factory setting is 1 hour.

Below is a typical application circuit. For most applications, simply run a servo cable from any channel of your R/C receiver to Screamy. Then optionally connect VBATT and GPIO depending on your needs.

How to Attach It To Your Aircraft

One thing we've learned about small aircraft is there is no one way to attach electronics. Because of that, we include with each Screamy a zip tie and 1" of Velcro! You can attach Screamy any way you'd like to your UAV, whether it's a zip tie, Velcro, electrical tape, or glue.

How it Works

Here's a block diagram of Screamy:

The brain of the device is the Atmel ATtiny45. This monitors the control pins SERVO, GPIO, and VBATT for triggering conditions. It drives the buzzer when one of the conditions are met.

The device is powered by an internal battery. In active mode (sounding the alarm every four seconds), Screamy will run for 3 days.

Screamy can be charged in-system, or from any other 5V source. While connected in-system, Screamy will run off of the aircraft battery.

Schedule

Here's the remainder of our schedule:

Screamy Program Schedule
Screamy Program Schedule

Parts will be ordered as soon as possible. We expect the longest lead items to take up to 3 weeks to arrive.

STRETCH GOALS

Stretch Goal #1: Choose your own Color!

If we reach $20,000, we will get different colors of heatshrink tubing to enclose Screamy. All who order a Screamy can choose from the following colors:

  • clear
  • red
  • blue
  • yellow
  • green
  • violet
  • black
  • white

If you order more than one Screamy, you can mix and match!

Once we reach this goal, we will add another one! Our backers will decide which one! 

STORY

Screamy began as an idea in December 2013 when I crashed my quad into a marsh behind co-founder Karl's house.

Then it became a prototype on a breadboard:

Then a PCB:

And now it's a finished product!

We have completed development and are ready for production! That's where we need your help!

Risks and challenges

We have invested our own dollars in developing this product. All we are asking for is help to go into production.

Kickstarter advises that it takes a few weeks to receive the donations. The longest lead parts of the project are the battery and PCB fabrication. We will order these parts as soon as we receive sufficient funds. If there are delays in receiving donations, there will be delays in fulfilling rewards.

Other Kickstarter projects have suffered from being too awesome and were unable to fulfill their rewards on schedule. Our company has planned for and is prepared to scale with demand. We will outsource work if needed to meet our schedule.

Don't forget to share this Kickstarter with your friends!
