Chromium plated steel (specially meant for vibration), plain shank, with frequencies marked. Conical pointed end for accurate and complete transfer of vibration to the experiment base. The frequencies are electronically tested. Packed in set of 8. One each of C-256, D-288, E-320, F-341.3, G-384, A-426.6, B-480, C-512. NOTE: Steel Tuning Forks are better than Aluminum Tuning Forks, because they Vibrate longer due to their heavier mass, thereby helping in experiment time.
To generate AC (alternating current) and or DC (direct current). On turning the wheel current starts to generate, on flipping the switch to ac or dc the corresponding bulb lights up. Open construction and all the parts are easily visible.
Scientific Plans
Vacuum Pump No moving parts yet produces pressures down to several torrs.
High Vacuum System Achieves pressures down to .01 micron for lasers, plasma studies, particle accelerators etc.
How To Construct Parabolic Dishes For solar, satellite, radio, heat or sound.
High Altitude Solid Fuel Rocket and electronic payload.
Portable X-Ray Machine Simple approach to building a home made x-ray machine. View the inside of sealed assemblies. Useful in many experiments - not a toy or for minors - Radiation hazard.
