Bucket Fly Zapper





Introduction: Bucket Fly Zapper

Bucket Challenge

Runner Up in the
Bucket Challenge

Pests are always a menace for us. We know that controlling pests is not an easy task. But when we find the weakness of insects we can easily control it. Their weakness is 'Positive Phototaxis' (ie, bodily movement of insects towards light). Here I constructed this instructable based on that idea - 'many flying insects are attracted towards Light!'

I here changed a bucket into a fly swatter with light. When insects attracted towards the light which I placed inside the bucket, they will die by the high voltage mesh when it crosses through it.

Step 1: Components and Tools Needed:

Current conducting Nets (2)
Hacksaw blade
Stepup Transformer
154nf capacitor
Resistors (32M, 3k, 1.2k, 680 ohm)
LED light
3v battery
D1616 transistor
Insulation tape

Step 2: Starting With Circuit

Make the circuit as shown in the circuit diagram. And solder it.

Step 3: Connecting 3v Battery

Here I have used a 3volt CR2025 battery. Now when you switch on the circuit the terminals we connected at the end of the circuit will cause high voltage at least nearly 400v. So pls be cautious.

when we switch on the circuit the LED will glow.

Step 4: Working With Bucket

Cut the bucket at two places in order to insert the net inside it. I here used thread to mark and cut perfectly. The distance between two cuts should not be so close and it should not be so far. 5mm - 1cm distance might be good.

Step 5: Fitting Light

Also make a hole at the centre of the bucket in order to place a bulb.

Then connect the bulb at that hole.

Step 6: Inserting Meshes

Now insert two meshes through the cuts.

Step 7: Connecting Circuit With Bucket

Now connect the circuit with the meshes. Connect the positive terminal of the circuit with inside mesh. And connect the negative terminal with outside mesh.

I used Sellotape in order to avoid short-circuit.

Step 8: Testing

Now we can check whether it works good or not. Touch both meshes simultaneously with a screwdriver, if it sparks it is working good.

Step 9: Final Step

Connect the bulb with the Power supply.

Step 10: It's Ready Now!

Test once again And just forget about insect menace. Insects automatically fly towards our light and will die.

I hacked my day;-)

What transformer did you use, primary and secondary voltage please.

Effects of giving a constant DC input to a transformer:
we know, for an inductor v=Ldi/dt, since v is constant here, the
i(current) will follow a ramp waveform and will keep on increasing till
the core saturates.
2. This meaning i will rise to a dangerously high
value and then stops changing, if i stops changing then the induced
voltage across the primary will be zero(as di/dt=0) thus short
circuiting the DC source.
3. Heavy short circuit current will flow,
overheating the coils, resulting in I squared R losses. Temperature rise
will exceed safe values and eventually the apparatus will catch fire.
Short circuit currents will result in radial magnetic forces that will
rip apart the winding and the windings become exposed to the atmosphere.
Transformer oil may catch fire under short circuit conditions.
5. So we must never apply a DC voltage to a transformer during operating conditions.

Pulsating DC can be applied to transformers, such the flux reset occurs
in the negative pulse period. The concept is to make the time integral
of voltage zero in one complete period, this helps in resetting the
flux. The ubiquitous Switched Mode Power Supply(SMPS) forms the
quintessence of this concept.

Come on, give us a break. Its an oscillator with a feedback winding in the primary. Yes, pulsing DC.

"Transformer oil may catch fire..." Lets get real, this is a dry transformer, no oil! Please, lets not over react. :-)

Congrats on being a finalist/runner up! I voted for this :)

Great ideal will try this summer at the our out door psrtys Thanks

How did you transform DC power with a transformer???

OK you humans, keep on making these great devices. (Which is very nice by the way.) We have taken over this ones feeble mind and he will build an electrified BBQ. So next time you go for a smoken' good hotdog, zzzaappp, back in to the dust where you belong. CLICK-CLICK-CLICK-CLICK-CLICK, eh, I mean HA HA HA HAAA !

that's pretty cool! thanks for sharing :)
