More than two years have passed since then, as I have installed it on your motorcycle “IZH-Jupiter 4” contactless ignition on the basis of voskhodovskogo generator, switch 262 3734 and a homemade diode mixer (Fig. 1.). Making sure the reliable working of my creations, and colleagues conducted such an improvement to your motorcycles However there were questions like, “I drew on your chart — explain why me doesn’t work.”
Ham radio
AUDIO CONTROLLER
From Nickel-cadmium batteries with a life expectancy of 100-200 cycles of charge-discharge. Discharge below 1V per cell leads to a sharp reduction in the duration of battery life. How to control a threshold voltage of discharge of the battery during operation? To have with you the measuring device is inconvenient. It functions best to hold the indicator — sound generator with a silicon Zener diode. Its voltage stabilization determines a controlled level of discharge.
THE FIRST STEP IN ELECTRONICS
Electronics today referred to as the catalyst of scientific-technical progress. It is really hard to find the field of science or engineering, not electronic engineering. Natural popularity that are mugs e-direction in students. As a rule, syut they have a narrow specialization, for example, radio club, club automation, etc. is quite justified. The enduring nature of the lessons (1-3 years) allows students to acquire a deep enough knowledge of the theory and the necessary practical skills by working in any one field of electronics.
“RUNNING FIRE”
With the approach of the New year interest in the “automation tree” increases dramatically. Everyone wants to decorate a beautiful Christmas tree with garlands of “live” light-driven commands to the electronic devices. One of them is the device to create the effect “running fire” — we tell today.
SAFE POWER SUPPLY
The inclusion of transformers on 400 Hz network, 220 V(50 Hz) using a ballast capacitor. If you look at the merits in diversity of industrial and self-made Amateur radio power supplies, it suggests the surprising conclusion. Basically they use the same (from a large item being sold) step-down transformers.
WHAT YOU REACTION?
Good response – what is it? More correct to say “speed of reaction” is the time that elapses between receipt of the alarm to the adoption of concrete measures. For example, the driver reaction time of 0.4 to 1 s depending on the complexity of the track conditions and the type of the vehicle managed by it.
FAN: OVERHEATING WILL NOT
Efficient and reliable operation of electronic devices depends largely on the temperature regime of each individual circuit element, especially if they work for 24 hours a day. Temperature, in turn, depends on the power load and output (key) cascades of stability of supply voltage.
ELECTRICITY GUARD
Who does not know the story of the brave poor man’s Ali Baba from the Arabian tales “Thousand and one night”, who overheard the mysterious words, in pronouncing of which opened a magical door to the treasure cave?
SVETOGRAD “THE SUN”
The creation of the original screen is of considerable importance in the design of light and music. Svetoteni fall primarily into two types with distinct colors and gammopathies — there takes place a combination of colors.
