Friends take an interest try build Tone Burst Generator be simple is. Try this circuit like sure because use IC 7555 , highly popular again. Assure that not sure difficult press the the secretariat of the senate S1 a loudspeaker will utter to come out immediately. When liberate S1 already the sound may loud again [...]
Bar-mode LED-cluster sequencer Can drive up to 16 clusters This circuit, designed on request, allows up to 16 LED clusters illuminate in bar-mode sequence. LED sequencing will start when the Brake pedal is pressed (or Turn Lights are switched-on) and, when the last cluster illuminates, all LED clusters will remain steady on until the Brake [...]
This is a pulse-mode transformer circuit that I have some experience with. I used this successfully in combination with a Polaroid transducer. Introduction The circuit can be used to generate a voltage of about 70V using a current of about 4 mA @ 6V input voltage. The use of an easily available stroboscope trigger coil [...]
