100 AND 1 OTHER USES !

While stocks last Lidl have 2Kw induction hobs, good for cooking but at £29.99 could be adapted to alsorts of other tasks ! Noel.

Other uses? Are you able to make bits of steel glow red hot with one of these things?

I bought 2, a nice one for the kitchen and the second one - who knows ? Re placing the flat coil for a normal coil, at 2 Kw things would soon get a pretty colour, could make an interesting hardening and tempering device. One might even be able to fit a pair of binding posts and a change over switch to the domestic one, attach the right coil for the job and do the heat treatment in the kitchen, running water for quenching !

It would be interesting to know if these hobs include monitoring of the induction coil to moderate what they do based on induced back EMF from the cook pot. It might prevent them from being repurposed.

Have you never needed to warm a pot of something in the workshop? Paint? Glue? Stuck together thingy?

soup?

I have long wondered about making a heat treatment oven from one. The plan would be a length of large seamless steel tube for the oven cavity, a layer of high temperature insulation round it, (probably) an air gap for blown cooling air, then the cylindrical coil driven from the electronics round it all. It would need a temperature sensor (thermo-couple) and control electronics.

Nearly all the heat should be generated in the steel tube, and hopefully the temperature inside that would be quite even.

...or you could just put a cast iron cooking pot on it!

The problem with that is that the basic hob is not insulated to stand several hundred degrees in immediate proximity, and by the time insulation is added to achieve that, inductive coupling may well be reduced too much to work.

Not with an induction hob, no. Propane torch, yes. (Stuck together thingies, not paint or glue!)

Probably not a good idea to be around an induction hob if you have any electronic equipment fitted like a pacemaker, defibrillator, cochlear implant etc. Be careful with VFDs as well, especially as many of us don’t comply with emissions control with our installation.
