Re: What's On Your Bench?

Question

Add to that, current projects!I have roughly the bare minimum...Wavetek 193 20MHz function generatorTektronix 475 oscilloscope (aging a bit..)An Eico 377 signal generator I never use, I just like it for the nostalgiaHeathkit (I didn't build it) V-7A VTVM.A few small cabinets/trays of parts, and a +/-15 2A bench supply.At the moment, I also have two car batteries in the room, for messing withthese beefy servo motors. circuit: needs current limiting on the MOSFET ala UC3844 type circuit.On the right, the induction heater project stagnates.  Actually, I was goingto add per-cycle current limiting today...And, hairy me in front of the bench...Tim--Deep Fryer: A very philosophical monk.Website @

Tim, I looked at the web page, but need a little background. I'm curious... what in the heck are you using that induction heater for? You doin' home-based bronze sculpture casting? Why the inverter?

Thanks, Sparky

Tim Williams · Answer

Check out the rest of my website (see sig).

Eventually, I want to melt about 10 pounds of steel. At the moment, I've melted an ounce or two of copper and done a few alkali fusions (producing sodium manganate and chromate).

The inverter is required to run this power level. I figure about 10kHz for

10kW.
