This thread is for anyone interested in building a charging device that I created several months back called a Vibreedo Coil. Since then I’ve moved on to more advanced developments so I’m pleased to publicly release this design. I hope those who are interested will test and post their results to confirm it’s output power and efficiency.
I must state before hand that this device will not run flawlessly unless the quality of assembly and components are used, therefore what is recommended below is for bench testing only. I will not take any responsibility for practical applications.
The Vibreedo Coil
At first glance, it appears there’s nothing to it, in which there isn’t. You wonder, “What does it do?” It does what it’s supposed to do without all the fancy components; generates, switches and collects (or waste). It basically works by placing a reed switch in what I call a “diffusion zone” which is the disturbance area of a permanent magnet opposing a pulsating coil. The switching, current and magnetic field are synchronized naturally in this repeated sequence:
1. a reed switch is turned on (contacts closed) by an opposing pole on the outer coil.
2. a current is triggered into the coil
3. the opposing top pole collapses turning the reed switch off (contacts open).
This sequence is repeated in milliseconds causing the reed contacts to flutter, this will determine the frequency rate. I have not concluded the actual clock source however from my observations it can either be the proximity of the permanent magnet (effecting the reed switch sensitivity) or the speed at which the magnetic field in the coil expands and contracts.
Building Instructions:
Create a typical coil by winding copper magnet wire (22-26g high thermal class) around a plastic spool with a 1/2 to 1” air core (or steel core). The size of your coil will be relevant to the sensitivity of your reed switch and load. For first time builders I recommend small spools ranging from 2” D X 2 1/2 L. The number of turns can vary (150-300 turns) however what is more important is the thickness from the outer wire to the inner core. I recommend spooling at least 1/4” to 1/2” of wire wound in uniform. In Fig 1.2 it shows an anti-clockwise winding so if you have pre-made coils make sure the south pole is facing upwards. You coil should measure about 6-8 ohms and 16-18 mH.
The sensitivity of your reed switch is expressed in AT (Ampere*turn) which I recommend ranges from 40-80 AT. Some reeds are rated 40-60 AT or 55-80 AT, which is fine. Solder or wrap two diodes at the end of each lead as shown in Fig 1.1
You’ll need a few various size neodymium magnets (square or round) about 1/2 x 1/2 x 1/8. You may need to stack a few to get the right magnetic field through the outer wire into the core.
Wire and connect the components as per Fig 1.1. (Be sure to leave a few inches of slack to move the reed around the top of the coil) then follow the instructions below:
Use a current meter on the negative of your primary power to monitor current. Also make sure to connect a charging battery before you proceed to the next steps.
1. First position the center of you reed at the top edge of your coil as per Fig 1.3. and hold it firmly. Be sure to keep the magnet away and don’t touch the leads on the reed!
2. For steel core position your magnet at the bottom facing north towards coil. For air core start in the center facing south towards coil. Refer to Fig 1.3 and Fig 1.4.
3. Slowly start to lift the magnet upwards towards the reed until you hear the reed fluttering.. What you will hear is a white noise or aerosol spray sound that will increase or decrease intensity as you lift the magnet higher and lower.
You may see sparks from your reed’s contact when the current gets too high (which will weld the contact leads together) so lower the magnet to avoid this. If you’re using a current meter I suggest to fix the magnet anywhere from 50mah-100mah. Repeat this process and be ready with a glue gun or tape to mount your reed and magnet in place. If you don’t have a current meter find the lowest point when your magnet activated the reed fluttering and mount it about 1/8-1/4” higher.
Troubleshooting:
1. Make sure you have the right pole facing towards the coil.
2. If your magnet doesn’t activate the reed switch then try a stronger magnet or stack a few more on. Also try to move your reed switch forward and back to get the right proximity. If that doesn’t work then your wire spool may be too thick.
3. If you see sparks on the reed contacts and your magnet is set to the lowest current, then your wire spool may be too thin.
4. If the circuit is shorting then check your connections and also the reed’s contacts with a magnifying glass to make sure it’s not welded together.
Low quality reed switches may burn out easily or create weld splatter in the glass. Rhodium tip contact leads work best. I recommend Hamlin DRR-129 Standard.
Additional Notes:
To protect your reed switch use a 90-110v neon bulb across connections 1&2. The neon bulb can take a small amount of charge so you may want to remove it for accurate measurement testing.
Reed contacts may weld together that will short the circuit and heat your coil.. Do not leave this device running overnight or unattended until you understand how it works and are confident it will run properly.
Feel free to ask further questions and please post your COP results.
