The RC4 Wireless RC4Magic DMX4dim wireless dimmer provides 4 channels of DMX-controlled low-voltage DC wireless dimming in a package only slightly larger than our popular DMX2dim. Four dimmers in one package is ideal for RGB color mixing. This video is a hands-on demonstration and tutorial of the DMX4dim.
The RC4 Wireless RC4Magic DMX4dim-500 wireless dimmer provides 4 high-power channels of DMX-controlled low-voltage DC wireless dimming. Capable of continuously delivering 500W at 12V, this workhorse dimmer can drive, for example, ten 50W MR16s! This video is a hands-on demonstration and tutorial of the DMX4dim-500.
Electronic candle flicker devices have become ubiquitious over the past 20+ years. Several manufacturers make them. They are relatively easy for an electronics hobbyist to build, too.
These little devices do not work well when driven directly by a pulse-width-modulation (pwm) dimmer. This is because pwm is a rapid series of power on-off cycles. Electronic devices will restart on each pulse, which disturbs their intended internal timing pattern.
The solution is an “integrator” that converts pwm periods into continuously variable DC voltage. When the pulse width is low, a low DC voltage is produced; when the pulse width is high, a higher DC voltage is produced.
A simple resistor-capacitor (r-c) network takes care of this! Watch this video to learn more.
New from RC4 Wireless: RC6 Wireless Motion.
Our latest RC6 mecanum firmware improvements allow the RC6 wireless mecanum drive to move on any arbitrary angle while remaining perpendicular to a reference, like the edge of a theatre stage. The drives are low profile and silent.
Off camera, this sample unit is being driven manually with an RC6-Freedom handheld transmitter equipped with a joystick. The piece moves in the direction the stick is pushed, and speed is controlled by how far off center it is pushed: full 360-degree control of direction and speed.
Historical Archive: James David Smith makes his first appearance at USITT Stage Expo, demonstrating the original RC4 system.
This system, based on a large rack-mount transmitter, is no longer in production. Everything you see demonstrated in this video can now be done with the much smaller and less expensive RC4Magic system.
One feature of the original RC4 that continues to be appreciated by numerous users is the 0-10V control-voltage (CV) inputs. This allows, for example, the automation department to control devices like wireless brakes and solenoids, without interfering at all with DMX-controlled lamps being operated from the lighting console. We have recently re-introduced this functionality with the RC4Magic CS1 Control Surface.
