ExpressPCB is proud to support a great Project! Boolean Box is a self-contained computer engineering kit for girls (and boys), designed for ages 8 and up. At our startup, Boolean Girl, we’ve taught hundreds of girls in our camps and classes to code using these simple, fun kits. As soon as they got their hands on […]

The goal for this project is to produce a low cost modular neuroprosthetic. By making the arm modular and localizing motors and their controllers within the components they control, the arm can be configured to fit multiple different kinds of amputees. The user control aspect is also quite different from most neuroprosthetics. I hoped to […]

WhitakerAudio – ExpressPCB Customer Spotlight The 40 W XL Stereo Power Amplifier is an all vacuum tube design intended for moderate power output levels. A tube-based amplifier imposes some unusual requirements on circuit board design, notably high operating voltages and considerable heat from the active devices. The typical operating voltage of this amplifier (plate voltage) is 425 Vdc. […]

Victor Fraenckel designed and built the “WindReader”, a device that measures the wind’s speed and direction. The instrument combines a commercially available theodolite telescope with custom electronics. The operator uses the WindReader to track a helium balloon as it ascends in the atmosphere to as high as 15,000 feet. The optical theodolite is adapted to include […]

A view of the ROV’s dome, left thruster, dive light and umbilical cord. In this photograph the sub is still wet after an ocean dive. Close-up inside the dome shows the camera and sensor board. The sensor board (designed with ExpressPCB) uploads depth and heading information to the operator. David maneuvers the ROV in […]

Jeff Karpinski of Littleton Colorado used ExpressPCB circuit boards to build a flight computer for his large model rocket. The rocket shown above is a 1/2 scale model of the British ASRAAM air-to-air missile. His rocket is 4′ 6″ in length and weighs 5 lbs when loaded and ready for flight. The body of the […]
