MAKE VIDEO PODCAST- Testing high speed flash photography kits…
With our kits you can capture high-speed events, splashes, popping balloons and breaking glass. It’s an adjustable flash controller triggered by light or sound. Our kit includes a high-speed flash, disposable camera, flash controller and fully assembled flash trigger that synchronizes the high-speed event and the flash. Also included is a 6-ft cable connects your high-speed flash to the flash controller, and all the tools needed to precisely time your high-speed picture. Flash controller is adjustable, so the flash can be triggered by soft sounds, loud sounds, a laser pointer, or a flashlight. The kit also includes digital output that can trigger other external flashes, such as the SnapShot II strobe light. But, how do we test each unit before we ship them? Here’s great video with Tom Anderson from Quaketronics showing you what we do! Link (MP4). Click here to get the video with iTunes! This video should work on PC/Mac/Linux/iPod video and PSP (let us know if it does not).
We’ve had a few emails and posts about folks who wanted to build their own lie detector, here’s one (and how it works) – “The circuit diagram of the Lie Detector is shown above. It consists of three transistors (TR1 to TR3), a capacitor (C1), two lights or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1). Suitable transistors to use are BC547, BC548 or BC549, or any other small NPN transistor. The Lie Detector circuit works based on the fact that a person’s skin resistance changes when they sweat (sweating because they’re lying). Dry skin has a resistance of about 1 million ohms, whereas the resistance of moist skin is reduced by a factor of ten or more.” 
Not bad for $44 – lots of project to make with this – “We have found many different uses for this little kit! Applications ranging from the traditional ECG/EKG monitor to the ‘Newly-Wed’ Love Synchronizer! One of the main reasons we designed the ECG1 was to answer a long running debate here at the shop. We wired up the ‘Boss’ and finally confirmed he does not have a heart! Use the ECG1 to astound your physician with your knowledge of ECG/EKG systems. Enjoy learning about the inner workings of the heart while at the same time covering the stage-by-stage electronic circuit theory used in the kit to monitor it.”

Not a bad deal for $49. “MIDISpeak Module – Version 2, The Talking Toy MIDI RetrofitAdds a standard MIDI IN port to your Speak & Spell, Speak & Read, or Speak & Math. Non-English versions also supported. Trigger thousands of sounds–words, word fragments, garbled speech, percussion and bizarre sound effects.”
