Why the name "Time Tunnel"?


If you were a baby boomer and sat watching TV frequently, you will know where the seeds of this name came from.

Russell has 50+ years direct experience in the arts, entertainment and electronics industry ranging from audio, general, industrial and RF electronics plus artistic endeavours such as "The Arts" generally - a very broad brush! A few items are not "artistic" at all but have historical significance.

MOST items offered are used but carefully inspected and where possible, tested.

Have a look around this ecommerce store, usually more items are added every day (or so)


Who is Time Tunnel?

Russell ... one man band!

Over the years a LOT of electronic equipment, electronic components, art works, music and other "art related" items have been gathered together which now need to find new owners.

He will ALWAYS strive to treat his clients with respect and honesty (and expects the same in return!), customer service is extremely important to him, a pretty old fashioned concept these days!


Russell's motivation

The most obvious motivation is that he has far too many items after all these years, boxes and boxes of them!

The second (but equally important to him) motivation is sustainability ....


Sustainability is a big thing for Russell, many electronic components can be re-used with confidence, particularly when re-purposed for custom designed equipment.

Sustainability is not just about NOT burying waste material back into the earth but recognising the energy expended to create the item in the first place, referred to as embodied energy, and wherever possible, reusing that item.

To give an approximate representation of how much energy was used in the WHOLE production process of an item, Russell has created what he calls an Ee (Embodied Energy) value, measured in Mj

The Ee value is an approximation only and usually measured in Mj.

Coming up with an Ee value is an attempt to take into account the energy used for extracting and processing of the raw materials, manufacturing of the component, distribution of the component(s) and final assembly of the component. In fact the measurement of Ee can become extremely detailed and technical, many tertiary institutions are involved in this field.

The information Russell is providing has the sole purpose of raising awareness that ALL components in electronics have an Ee value, this Ee value Russell is indicating on some of his products is a GUIDE ONLY.

The main point here is to recognise that the amount of embedded energy varies between raw materials and the awareness of the Ee value can promote the convervation of products instead of burying the item in the ground and the associated risks of poisoning our environment.

There are many many websites providing information about Embodied energy, HERE is just one and I have used a couple of their graphs to illustrate just how much embodied energy various materials use.



Now those estimated 'approximations' of embodied energy on some of my advertisement pages may look meaningless, for example what does 12.5Mj really mean?

Remember this is embodied energy, an estimate of the TOTAL energy consumed in the obtaining raw materials, processing, assembly etc to eventually end up with the item being offered.


A typical mobile phone uses around 29Kj to charge a "standard" battery

By comparison, one of my standard 12" record albums has an Ee of 12.Mj - in other words, the energy used to produce that record you may be holding in your hand is 400+ greater than charging your mobile!

What's worse, we then bury the records in the ground! Such terrible waste and not to mention to leeching of plastics into the surrounding earth. We can do better than that ...
