Extinguishing, or cooling, an electric car (EV) fire

How to cool down and limit the radius (spread) of an EV on fire? To suppress an EV on fire on a road, or onboard a car carrying ferry?

The facts are :

Adding Aux to old car radio

Aux + iPod

How to add an Aux port, a 3.5 mm “headphone” jack to your radio.

Aux port

As my van is rather old – as is the radio – but working, I figured out how to add an aux line-in to the radio unit.

Recycling – an Ecological deed

Eco-deed

Continuing on my writing about the recent (15th March) youths’ demonstration – not having done their homework before marching against the government(s) – I thought I dig a bit deeper into Recycling. About what can be done against climate change.

At least give a peek into my personal findings of the state of the world.

8 mm projector conversion to LED

From halogen bulb to LED

What if one could increase the lamp life 100-fold, and avoid all that heat – that would burn the film in case the film would stop running…

Story

3 generations were seated to dig into a number of film rolls from my childhood, to travel back in time some 40 years. We got through 20 minutes of film, when the light bulb came to an end.

The projector – the patient

Fujicacolor 10M

Life expectancy is 25 hours, so having lasted since my childhood – that in itself was a lot of hours than the listed expectation.
