I think a blog is in order... so much is going on.

So, my very first ‘Eutechnics’ blog.

The service I have been providing for more than a year now has grown out of all expectation. I was only helping the poor souls that did not know how to repair Time Capsules and I’ve almost lost count of the number I’ve fixed and modified but it’s climbing to silly figures like about 90 or so. Any money I have made has all been ploughed back into the ‘business’ to buy more bits, packing material, ink-cartridges for the printer, etc. Recently a good ‘job lot’ of Nichicon capacitors at 105C spec and very low ESR to fix the power supply units that land on my door mat.

I have had a few chats with Jim F in Holland about a TC I sold to him a while ago (2TB modified - in need of a good home). He was going to make the cooling fan quiet come hell or high-water, so pulled my creation apart with his bare hands (and a small crosshead screwdriver). His experimentation was both exemplary and persistent. He achieved a degree of success, messing about with different fans, voltage dropper circuits, MOSFET switches and slowly charging capacitors. His conversion seemed to work well, it certainly made the fan run slower and the noise disappear into the background.

It got me thinking... I really need to do a proper job on this fan drive (not that Jim’s job was not ‘proper’) and I needed a one chip solution, if possible.

I have chosen the pathway of the microchip. A prototype development board is on its way and a couple of DIL devices to play with. Nice :-)
Playing with circuitry on the bench has not been done for many a year - I need this challenge.

My life at present is turmoil of a self-inflicted kind. Fiona and I have moved into her parents old bungalow, with the intention of rebuilding it to a high spec, low energy, green-ish home.
Why let a mid-life crisis overtake you? Take on a project like this and drive yourself mad, its much easier! Not a few things are wrong with the house... EVERYTHING is wrong with the place.

In between putting in triple glazing, a ground sourced heat pump, underfloor heating (water pipes), a wood-burning stove. I will also be building a new 3 bay garage with office/workshop over, trying to fix the rattling ruin of a ride-on lawnmower to cut the grass of near 0.5 acre of lawn, as well as extend the house for a new kitchen. Oh yes and work at my day job of selling energy management systems and walking the dog. I also fix and modify TIME CAPSULES. Happy days.
