Things to do to

[Manfred Amoureux]

next discussion : tuesday 22nd of July, 20:30

Tasks assigned in red. Confirm you are ok.

Supplies and tools :

 - climbing gear (Roy : see your landlord. Or anybody else)

 - 60A DC switches. At least 1. 2 or 3 would be better. Jean and Manfred

 - price quotations for spare parts and cables for the turbine. Roy

 - get some tools (especially charged cordless drills). Voltmeters are welcome. Roy, Manfred, eventually Jean and JB.

 

Plus the supplies we wrote down we would last time :

• More connector boxes for sizes of 6, 10, 16 mm² and above. The cables on the DC bus are thick and we had hardly enough of them. Manfred

• Same remark for the connecting ends. Manfred

• Take an angle grinder for the earth rod (or another earth rod). Roy, do you have one ?

• Some more shrink tubing in wide diameters. Manfred

  Good lighters. JB

• Cable ties. Manfred

• Some good battery terminals if they are intended to be replaced (mind the + and - !) ? Anybody who can find some at a car scrap dealer. JB ? Roy ?
  Explanation : last time we had troubles connecting the batteries to the cables using battery terminals exactly similar to those used for cars (see there) as we did not have enough + and - (they are not exactly the same !) so we had to tinker with them. 

• Water level. (Niveau à bulle) Roy ? Jean ?

Personal gear :

 - JB's guitar. 

 - sleeping bags

 - torches or flashlights

Hello All,

Questions to Oda:

1. Please could I use the pink twingo from Thursday 2 July to Thursday
9 July to go to Oberried?
2. Is it possible to use your brother's tools from Saturday 4 July -
Wednesday 8 July?
3. Is timber easily attainable in Oberried?

Note!! I won't be able to make the Skype meeting this evening due to a
work commitment that I forgot about. Sorry for this glitch. Could we
maybe make it tomorrow evening (Tuesday 22 June 2010 @ 20:30)?

Some feedback on my accomplishments this week:

I spoke to Uta and she is fine for us to come twice this year
(beginning and end of July). In fact she was THRILLED!!!

About my contraption for the wind mast to make it easier to work. I
can't get an aluminium ladder for less than about 50 Euros so I'm
strongly considering building something out of wood. Will check with
Uta whether she has some appropriate timber lying around or whether it
is easily attainable on Saturday 4 July in Oberried.

I still need to ask Uta about a tool inventory down there.

>  - climbing gear (Roy : see your landlord. Or anybody else)

[Roy]
This week I will pick up the necessary climbing gear from Dirk
Steinhaus (a friend of my landlord).

[Manfred]

>  - price quotations for spare parts and cables for the turbine. Roy

[Roy]
Prices for Rutland spare parts is attached.

I haven't yet got prices for 4 and 6mm² cables with UV protection and
capable of self support (i.e. mechanically strong enough to hang,
unsupported, between two points), but I have confirmed with the
Fraunhofer IWES bookkeeper that I am allowed to purchase from IWES
suppliers for private projects. This week I will attempt to get some
prices on cables.

[Manfred]

[Roy]
I will be able to bring along a voltmeter and most probably a cordless
drill (still to confirm on this though).

[Manfred]

[Roy]
What about a terminal block (http://tinyurl.com/37cbrbd) instead of
those chocolate block connectors Manfred? What I don't like about them
is that there is no guarantee the screw makes contact across the whole
cable. I would prefer having wire end connectors or terminal rings on
all the DC (and possibly AC where appropriate) wires like this:

Take a look at this nice DC setup:

And here is a nice page with it all combined:

With this approach there is less chance of failure. What do you think?

[Manfred]

[Roy]
Yes I think I can borrow one from my landlord but I will confirm this.

[Manfred]

[Roy]
There is a scrap yard near my house. I will take a ride up there and
see what I can find.

[Manfred]

> Water level. (Niveau à bulle) Roy ? Jean ?

[Roy]
Yes I think I can get a spirit level too.

Speak soon...

Hello to all.

You did not remember well, Roy : the next meeting was already set at tomorrow evening 20:30.

I also think we can sort out something out of timber when we'll be there. In the worst case scenario, it will still be possible to buy an alumium lader at the next DIY shop in Freiburg.

I was not able to lay my hands on a voltmeter. How many can you get ?

[Roy]
What about a terminal block (http://tinyurl.com/37cbrbd) instead of
those chocolate block connectors Manfred?

Agreed, if I can find some.

 

What I don't like about them
is that there is no guarantee the screw makes contact across the whole
cable.

all the DC (and possibly AC where appropriate) wires like this:

Last year , I had some special pliers for the connecting ends. They were from Witzenhausen, so we'll have to find something that does not require special tools this time. Beside, the type of connecting ends depends on to what kind of terminals to which we must connect.

Talk to you lads, tomorrow.

Manfred

HI,

 

I won't be able to be here for the meeting, I had completely forgotten.

 

I'll be here at 21h15, could we delay it a little, as Manfred told me he won't be on time to.

 

See you

Dear all...

Quick visual aid comment by way of 2 links...
rather than:
http://tinyurl.com/33fg3ko
consider instead:
http://www.jamestowndistributors.com/userportal/woeimages/Electrical/54668.jpg

I like these much better because you need not completely un-screw the
terminal to make a connection... I'm prone to re-doing things several
times before I get it right and this style connector greatly speeds up
the process.

That's my 2-cents input. Wish I could join you guys this time around
again, but alas, my time in Europe has expired.

Cheers,
-Tyler

[Manfred Amoureux]

A good option if we cand find some.

PS: Roy found that very interesting online shop : http://www.12volt.com.au/

[Roy]
Thanks Tyler! I'll see whether I can find these. I can certainly find
the closed loop ones though.

Another thing I've though about for speeding up the AC wiring are wire
terminators such as the twist on type:

http://en.wikipedia.org/wiki/Twist-on_wire_connector

or butt connectors:

To get up to speed with my AC wiring skills (non-existent to date)
I've also been watching a few online wiring videos here:

Regarding the wire terminators, I considered them last year : they seem handy, although expensive

I eventually went for the type we used, because I had access to the special pliers needed and it was less expensive, then.

What type did we use again? Send a pic please.

Remember I will buy the special pliers we need for myself if we can't
get them from Oda's brother.

[Manfred Amoureux]

I would like to draw your attention onto the fact that the choice of a wire terminal is conditioned to what it will connected to.

The type that you recommended earlier :

Is not to be used with the usual connecting blocks ("choc blocks"), for example :

and you also cannot use it on the standard female terminal ends of most appliances (the inverter or the charge controller), which are similar to choc blocks.

So we had used something similar to these "pin terminals" (not exactly - I cannot find a proper image) :

Which fits much better in choc blocks.
