sLEDgehammer

sLED logo small
The sLEDgehammer is an interactive light challenge that harkens back to the classic carnival Sledgehammer game. But here, the aim is to convert your peak power output to a beautiful light display. The sLEDgehammer is accurate, motivating, and visible from anywhere in the venue. It’s a fun way to get your event participants thinking, cheering, and breathing.
The 11′ Tower and Stand are a great way to show pedalers their power.

The sLEDgehammer can be purchased as a single-player challenge or a dual:

Rules of the game:
Pedalers must overcome the challenge phase in order to see the reward sequence. The faster they pedal, the more lights turn on, making it harder and harder to keep increasing the system voltage. If they push the lights all the way to the top of the tower, and keep them on for 3 seconds, they beat the challenge and win the game. Their stored energy is then used up in a dazzling display of light.  A difficulty knob makes the game easier or harder. The peak effort required to win is about 200W for the Easiest setting and 600W for the Hardest. In the Dual sLEDgehammer, everything is the same. To decide the winner, you start the two riders at the same time and give the win to the one who pushes the lights higher in the tower or gets the victory sequence to display first.

The elements of a sLEDgehammer:
  • An efficient bicycle generator, such as the Electric Fender Blender Pro.
  • The sLEDgehammer circuit, which comes complete in a strain-reliefed enclosure with an Ultra Capacitor and all power cables.
  • 5 colored LED panels standing to a height of 11 feet tall.
  • Halogen lights at the top to win the game.
  • A wide base untippable tripod stand.
The Bike: Any of our hub generators will do. But more than our other activities, pedalers on a sLEDgehammer tend to use their whole body to try to beat the game. You may benefit from additional stabilization of your generator. The Electric Fender Blender Pro, with its 3′ wide stance, is particularly well-suited to this application.

The Circuit: The sLEDgehammer circuit is the brains of the operation, calculating watts as you pedal. The sLEDgehammer comes in an enclosed, strain-relieved circuit capable of handling 1500-Watt surges in power. Depending on how many LEDs you connect, you may need all that power handling. People will try to break this machine. The sLEDgehammer circuit runs cool, calm and collected even when your participants pedal their hardest.

The sLEDgehammer runs on an Arbduino Pedal Power microcomputer, using the open-source Arduino platform. What this means is that you can optimize or change certain parameters to improve the activity.

Custom Installations:

The sLEDgehammer can be installed in several ways. Our favorite method is doing large custom installs like the ones shown on this page. They can either be done for a single event or on a semi-permanent basis. Custom installations use the same components: bike, lights, and circuit; and can be tailored to your event, activity, or facility. We work with you to deign and implement the sLEDgehammer. We then provide either full installation and crew at your location, or help and guidance for your crew prior to the event.

Recommendations for output devices, i.e. Light:

Please see above about “rules of the game”. There are two lighting segments of a sLEDgehammer — the Challenge Phase and the Reward Sequence. To make the Challenge Phase truly challenging, you need to connect at least 200 Watts of lighting, perhaps as much as 500 for the fittest riders.  The most impressive way to achieve this, and the best option for a large space is to use LEDs both the challenge phase and the Reward Sequence. This makes the Challenge Phase visible to much larger groups of people, which increases the crowd interaction. A lower-cost substitution is to use incandescent bulbs for the Challenge Phase, which has the benefit of highlighting the comparative energy efficiency of newer lighting technologies. With incandescents you can make the Challenge Phase truly challenging. Incandescents will cost less* because you need far fewer of them to achieve the Wattage goals of the Challenge Phase. (* That’s also the reason they are worse for the environment.)

  • Combining RTB activities to engage crowds at conventions and other large events

    This latest video, shot by our friend and partner, Natan Lawson of Wheely Good Smoothies in Baltimore, shows how eight of our rental activities created a large cohesive space with a large exhibit at the recent Democratic National Convention in Philly.

     

    Producers of large events are used to working in large spaces. Spaces that are typically empty and in need of shape, definition and life when they arrive. Just as it is the job of the wedding producer to remember the flowers, it is the job of our customers and rental clients to plan for both the visual impact and the function of everything in their spaces.

    pedal powered game

    Our Pedal Powered lighting challenge, the sLEDgehammer, has escaped the tube.  We’ve both advanced the circuitry and the creativity of this piece of gear, making it even more of a crowd pleaser.

    The sLEDgehammer is a Pedal Power game where you have to pedal really hard (but not for very long) to win. When you win, the power you’ve built up by pedaling gets unleashed in a dazzling light sequence. In the example above, a river appears to flow down the courtyard away from the pedaler, then the Peace & Love sign lights up. The 9-segment ‘reward’ sequence lasts only a couple seconds. When someone wins the game and sees the sequence, there’s a palpable release of energy. The celebrations are awesome to see. At the holiday party where we set this up, people were shouting “Peace & Love!”
