Oldie but goodie…In our other crystal radios we wound the coil by hand. In this project we use a much smaller coil with a ferrite rod inside, from our catalog. The ferrite rod allows the coil to be smaller, and it can be moved in and out of the coil for coarse tuning. Link.
Game sound emulators for ColecoVision, Atari, Sega Master System, GameBoy, NES, and even IntelliVoice. And you can plug them into your sound software as VSTs (Windows-only), or, better yet, into your own custom sound patches in Pd (free – Mac/Windows/Linux) or Max/MSP (commercial – Mac/Windows).

Although it is simple, it can reveal the craters of the Moon and the satellites of Jupiter. It is also very useful for demonstrating lens aberrations. You really need to build this telescope as a necessary step towards understanding the solutions employed in the second and improved telescope model. In the section “From Lenses to Optical Instruments”, you saw how a telescope works; here I simply remind you that the objective lens produces an image of the object observed, and this image is magnified by the eyepiece.

The BomBot is a modified 4×4 remote controlled truck that has been equipped with a pan and tilt camera and a charge dispenser. The robot can reach speeds of 30 to 35 miles an hour. This compact and versatile system, which costs roughly $6,700, is being deployed in rigorous environmental conditions where more expensive robots with a greater logistical burden are currently used. In just 90 days, the first prototypes of the system were delivered to users in the field.Link.
