We need electric vehicles

You do know that in about sixty years there will be no more oil to make petrol, don’t you?

So what do you think will make your car move then?

Aboriginal culture

Aboriginal culture is not something to be promoted but to be denied existence.

Why you need to travel overseas

The whole point of travel from Australia is to experience other cultures and see the evidence of their history

Homemade iontophoresis machine for Palmar hyperhidrosis

Palmar hyperhidrosis is a condition that has a big impact on people's lives because they have sweaty palms.
If antiperspirants have not been effective you can try iontophoresis which involves buying a machine that costs from $400 to $2500 in which you immerse your hands.
Alternatively you can make your own device to perform iontophoresis at home. It will cost you less than $100 with a simple power supply. If you have a need for a sophisticated power supply this can be about $250 but you have a laboratory standard device for experiments.
The device utilises pans of water to conduct a very small electrical current through the skin's surface.
Power supply. Jaycar sells this power supply for $175 but you can buy a simple one for $37.

The setup

Trays – Two plastic 2L storage containers

Electrodes. Buy a sheet of aluminium from Bunnings and a pair of cutters to make two electrodes. Attach wire by soldering or use a small bolt and nuts. The sheet will cost about $20. Cutters are $15.

Mat to separate hands from electrodes. Big W has two of these for $3 and you cut them to size.

The water conducts a current of about 6mA.

Weekly sessions lasting 20 minutes may provide relief from excess wetness.
