Pumping it with a potential of about 5 amps at 12 volts should be sufficient. The problem is, if the spirit, entity or object attempts to draw too much energy at once, it might cause problems. It would be a good idea to limit the current or put an adequate fuse in place to the coils so it doesn’t burn something up. It would also be interesting to monitor the amount of current drawn from the coil.

It’s not a very portable solution, but it might yield interesting results for those with the time and patience to try it out!

You can take various power transistors and something as simple as a 555 timer or as complex as a PIC or AVR processor and experiment with different pulses and frequencies.

A UPS lead acid or car battery can generate enough of an EMF when it’s shorted to a short wire (no coil) to wipe clean a credit card stripe from a couple of feet away, so a properly wound coil driven with a variable frequency inverter circuit is sure to get results!

I’m going to order the 120vac chime transformers today. How do you have them setup?

I’ve never played with chime transformers. Do they need a power supply or do you just have them connected to a power cord?

With the second EM pump, I used two chime transformers with even stronger EMF distance results that started about 18 to 22 inches away. No high heat involved with the transformer.

I found that there are three chime transformers rated at 40 watts and go for the price of $15 to $25 dollars a piece. I am seriously thinking about either building a third version or gutting the first EM pump of the transformers and replacing them with the three chime, 40 watt versions (unless I can find a four chime version). Based on what I have seen with moving from a single chime transformer towards a two chime version and seeing increased EMF results, I feel somewhat sure that I should either see an increased distance as well, or better strength all the way around the project.

I still haven’t given up on a battery operated version of an EM pump, and I have a few strong ideas on how to build one from off the shelve parts, but I can’t see me doing this until later in October or sometime in November. I might be wrong but I do not see a battery version giving off the same levels of EMF readings like an AC powered version does. We’ll see.

Next, I introduced the pump to the group and they were eager to try it at a location that had been investigated once before. Their success was next to nothing the first time they went there, but this time the pump appeared to have helped. After setting up all of the equipment and then exiting the home, we allowed the home to sit and rest for around +/- 15 minutes *we also did this every time the teams switched up). We then went in and performed an investigation. Nothing seemed to have occurred the entire evening while we were in there (normal human hearing, our sight or video, or touch/feeling). This evening one of the leaders just happened to check one of the digital recorders tonight and found several instances of walking, singing, and some voices; and this all inside the home while nobody was within the house. The rest of the evidence still needs to be examined, along with the recordings from that same recorder, but the group leader is extremely happy with what the pump may have contributed towards collections. If there appears to be more EVP evidence, I will be building more units of the box that I described and built. I may build one with four transformers inside to see how it compares with the one that only had two; especially since the box remains cool to the touch. Just wanted to add this to my previous postings.

I still would like to figure out how to make a higher powered DC unit that doesn’t use AC power, but I’m looking into a couple of ideas.
