  • building the poor-mans mini tesla coil ( slayer exciter)

    Refer to the troubleshooting step for the small version. I think you will find the answer there.

    Creating Alternating current

    Relays can very easily be configured to self oscillate, simply by either connecting the normally open contacts directly parallel with the coil, and having a lamp in series with the coil powered from a source, OR by connecting normally closed contacts in series with a coil, and connecting that to power.You will have high voltage spikes across the coil, and could get a nice tickle-shock from it, probably enough to startle you or blow a multimeter up, both of which I did.The contacts will also wear out very quickly as an arc is drawn when the contacts come apart. I have caused a 50A car relay to melt in this way, and destroyed many smaller ones in seconds. I also used a refined version of this self-oscillating setup to drive and test ignition coils, with great success and 1 inch sparks fro...see more »Relays can very easily be configured to self oscillate, simply by either connecting the normally open contacts directly parallel with the coil, and having a lamp in series with the coil powered from a source, OR by connecting normally closed contacts in series with a coil, and connecting that to power.You will have high voltage spikes across the coil, and could get a nice tickle-shock from it, probably enough to startle you or blow a multimeter up, both of which I did.The contacts will also wear out very quickly as an arc is drawn when the contacts come apart.

    I have troubleshooting tips on the last few steps. If those do not work then ask again. Good luck.

  • building the poor-mans mini tesla coil ( slayer exciter)

    This circuit took me weeks to perfect. It's hard to tune due to the chaotic nature of its operation. Take a look at my last few steps for troubleshooting.

    You can also alternatively try making your own MOSFET buffer driver with a couple of transistors. Use 2 (a NPN and PNP) transistors in the emitter follower configuration with the base's connected together and the emitters connected together. The emitters go to the MOSFET gate, and the base is fed from the feedback pin. Due to the nature of PNP and NPN transistors, protection diodes are not critically necessary, as the PN junctions will do the trick. The transistors are acting as emitter followers, so the NPN collector is connected to Vcc and the collector of the PNP is connected to ground.

    It's hard to say, I killed all my DS0026's working with this circuit, too. And I have no plan to buy them. (I only used that chip because I had them in my antique junk bins.) Look up the datasheet and have a glance at the Absolute Maximum Ratings for your device, it will list all the things that, if you exceed, will result in the magic smoke.
