Going cheap or make it yourself?
Give blokes in Occupational Health and safety a hart attack I reakon. :D
Wow, thats a great idea, can you post the circuit diagram please
I wonder what happens when it gets wet? :D :eek: :eek:
The contact area on the pins into the coils of copper wire looks better than many of the commercial things we buy here (just a slot in a flat piece of thin copper sheet)
BUT Being a boring old nut ... Please don't even think of doing the above in Aus. Double volts in Aus, No earth, No certainty of polarity, No protection against overload etc etc etc -> a nasty outcome
... I guess the 3 pin Ausie plug has something going for it!
Another pic that I had but have now lost shows a shower in South America.
The shower head has a heating element in it but the power lead runs down the wall beside the shower, no curtain, to an open old style knife switch. Wish I had the pic lol.
I have seen something similar to that in use at an old factory.
Great Stuff!
We do a fair bit of work in Indonesia. Now, they're 'great' people but their electrical safety pracitices leave alot to be desired.
We were installing some weigh-in-motion detectors on a highway, but unfortunately, the village blacked out everytime we turned on the concrete saw. So a call went into the Electricity Department and 10 minutes later out comes the 'official repairman'. (He also does the towns plumbing and telephone work).
Now, he didn't bother to cut the power to the line, he just finds a piece of wood for a boost and then shimmies up the pole to have a look.
The other photos show a the concrete culvert where the equipment is housed. It regularly fills with water so they installed a 'pump' to keep it all dry. The closeup shows a the plug which connected the pump to the mains.
We've also had cases of steel bars being used for extension cords and 1 indo worker electrocuted in a puddle of water.
Oh, and by the way, these photos were taken in Aceh pre-tsunami. Everything you see is gone. :( People, Village, Equipment, everything.
Oh and I forgot to say. The man up-the-pole also had the job of turning the pump on and off every day. When our techs arrived for a checkup, they find the culvert full of water (photo 2). IT seems his job was to turn the pump on and off, if the pump wasnt working then that's not his job/problem. I'm not joking here, this guy went and switched a non-working pump on and off everyday for a month before we realised that something was wrong(no data)
**Vent-mode-off**
Many times in Malaysia I watched the loacl handyman/electrician check for power.
Just short it wath a screwdriver, if it sparks it's live, usually while balancing on a ladder made of packing crates.
We used to use the generators for night flying ops instead of relying on the mains, just had to shine the lights onto the generator first to check for Cobra's and Vipers lol.
From what I have witnessed in Asia that is a pretty goog job.
In Korea they stick welding rods in the main outlet and clip on using aligator clips until the circuit breaaker or fuse trips then they remove 1 item. This is using 240 volts.
I the Phillipines and China they just shimmy up the pole and tap into any ariel power and run down to shanty town. All and sundry tap into this.
In China I saw a HIGH Votage transformer low enough to the ground that one could actually enter the HV terminals without a ladder. No security at all
Life is very cheap.

A slight digression but this is what I pulled out of a roof.
Home owner had attempted to put in several TV points throughout the house and he wired the splitters himself.
Antenna ran to two way splitter, off to one room then to next splitter where the process was repeated.
Eight of these and reception was somewhat rather poor, don't know why :rolleyes:
Techo's should love this :D

There is no margin when it comes to safety. My nephew used to install cable TV in SydenKnee.
A cowboy had laid his 240 lead under the carpet. Nephew spent a week in hospital after cutting into it, lucky to survive.
No longer able to work in that role anymore, but now enjoys running a tackle shop and taking fishing trips. So guess some good came from it?
IF YOU DONT KNOW HOW TO DO IT PROPERLY DONT TRY (better still get a sparkie in), YOU COULD KILL.
Line lefty, you were working in the more sparsely populated parts of Indonesia. thats why this bloke had more than one job. contrast to downtown Jogjakarta in 1992 or there abouts. i went to post a letter. i had to give the letter to one person, and the money to a second person. the first person gave my envelope to a third person who put a stamp on it. the second person then handed my money to a fourth person who gave me change. meanwhile the third person handed my letter to a fifth person who dropped the letter into a slot. 5 people to do what one could have done - its like work for the dole in australia. they create work by splitting up one job into 5Quote:

This bloke earns a nominal salary of $1000AUD per month, and he's just bought himself a $450K apartment in South Yarra. Do I smell corruption?
I can confirm that this is the dead-set truth. We called them frankenstein showers when we were there. You stand in a poorly draining shower, throw a big switch, watch the lights dim and hope that you don't get killed. Most of the wires run across the top of the wall/tiles. Scary as sheyet. :eek: :eek: :eek:Quote:
