Tried every damn possible thing... No results.. Went to buy a similar circuit in the market, the shopkeeper said he stopped selling those because the output changes whenever any appliance starts :lol:. So, the problem is everywhere.
So I shelved the project. I tried to make it low cost but...
I'm using a 7809 to keep the voltage at 9 volts Vcc since I'm usin a 12 Volt transformer for AC to DC conversion. Do I still need the 7805 or is the 7809 sufficient for the job ?
Sorry for the late reply...
@Audioguru : Sorry I'm not being able to provide you the circuit diagram because of my horribly slow internet speed doesnt allow me to upload images, I'm using a text only version of the website. But, I hooked up the TSOP1738 in the following way : a 1k resistor from...
I think I didn't describe my problem clearly. The circuit works fine when I'm using battery power. It only starts malfunctioning when I'm using an AC to DC converter to power it up.
The TSOP1738 is connected as recommended in the datasheet. The circuit is soldered on a veroboard. I can't find out the exact source of the problem... but it occurs whenever some switching takes place in the house.
Hi all,
I've made a Remote Controlled switch using TSOP1738, a Timer 555 and a CD4017. The working is this :
1) The 555 timer is set to monostable mode with the trigger input connected to the output of TSOP1738
2) Whenever pulsed IR falls on the TSOP1738, it triggers the timer.
3) The timer...
Wow.. So the flourescent tube should light up if I live close to the high-tension lines, but won't I get an electric shock ? The current will flow through my bod to reach the ground right ?
So the reactance of the capacitor should always be greater than the load ? In that case, what should be the optimum value of the capacitor for lighting LEDs, say 2-3 of them ?
Okay I get it... My concept has been cleared. But either it will give a high voltage or the neon will glow... Why it will give high voltage even if the neon doesn't glow ? Wouldn't it mean that the voltage is too low to light the neon ?
Okay here's another question... When a load of... Say 1k.. Is connected to the capacitor power supply, then the reactance offered by the capacitor is much less than the load... So, a large voltage would appear across the load, probably blowing it... Isn't it ?
But the bulb doesn't glow when my slippers are on ! As per your answer, the bulb should glow even when my slippers are on because my slippers are at zero potential.
Okay, so that's why they are using capacitors ! But, the lights which we see in the market are rated as 90-270 V. That means they will work in a significant voltage range. If the reactance of the capacitor is fixed, then how come they claim such ? Wouldn't the voltage fall too low at 90V ?
