Don't hold you're breath on the video - as said before, no sound, and crap cameraman. You can't really tell the thing is running!

I'll try and get some better video tomorrow. With sound.

Well done mate.

Always a great felling when it bursts into life for the first time.

And what a great idea for tagging the wiring.

GreatOldOne · #43 6th January 2009, 18:18

Thanks - I have to confess that it's not my idea - I saw it here:

http://www.lbthosting.com/dutton/others/ReWire.pdf

And like all good ideas, I immediately nicked it.

I've updated the blog page with some better video, which now has 100% extra added sound.

It's also on You-boob as well:

Awesome. I think you might need a (better) silencer for the SVA though ;-)

I checked out the ETB web site you suggested (for instruments). They are certainly cheaper than Green Gauges and I like the no nonsense advice they give (on the website) as well. Just as well I have been pontificating about ordering from Green Gauges. You may well have saved me some money! (Make the wife happy anyway...)

Excellent! Glad to be of service. Just don't tell the wife... The savings will only get converted into shoes...

I think the Speedo works out to be more expensive than the GG one, but everything else is so much cheaper it more than cancels it out. (by my calcs the whole set with senders is over £200 cheaper!)

The chap I spoke to on the phone when I ordered seemed very pleasant, and genuinely seemed interested in what I was building. He also confirmed that the speedo will work with the E30 diff sender, so that's another cost removed.

Their lead time seems a whole lot shorter as well.

It is brilliant when you strike an engine up for the first time - well done. I still get a tingle of excitement run down my neck even by other builders videos, and remember gettting an old J2 Comma van engine running in the middle of my Dad's work shop 35 years ago when I was 13 or 14 years old. I used a milk churn for the radiator with pipes dangled loose in to it and a milk bottle for the petrol tank!! Great fun. And well done again for getting it to start first time - no wrong wires, missed earths etc - very impressive.
As Rob says, I think the silencer will need a bit of work??!!

Thanks Mike - and thanks to everyone else's congrats. I'm still on a high from the first fire-up, especially as that was the first engine I've ever rebuilt.

The advice I've gotten from you lot has been invaluable. Cheers!

It's true then, what I've always suspected, the universal desire of women for shoes.......

They should take a week to arrive - I'll post some pics when they do.

Hi Jason

Did your instruments arrive yet? I would be interested in seeing some pictures and your opinion of them if they have?

Cheers

Robin

GreatOldOne · #50 13th January 2009, 17:30

Not yet - I'm expecting them some time this week. I'll post pics and opinions as soon as I have them.

GreatOldOne · #51 14th January 2009, 13:01

On a related note, does anyone know how to wire up a low fuel light? Looking at the schematics for the fuel guage and sender from ETB, there isn't a provison on either for a warning light.

Obviously it wants to come on before the tank reads empty, so I guess that I'd need a circuit that would interperate a set reading / resistance from the sender and switch the light on...

Any ideas?

GreatOldOne · #52 14th January 2009, 21:53

After much googling, I've found this:

http://users.telenet.be/miata/english/misc/lowfuel.htm

Which would seem to do the job - for an MX5, and the very last entry on this MOC thread has a circuit:

http://www.marlinownersclub.com/foru...read=666&cat=0

But that looks as if its more for calibrating mismatched senders to gauges rather than just the light. I assume I shouldn't have any issues in that area as my gauge and sender are matched (and you'd assume calibrated for one another) by ETB.

MartinClan · #53 15th January 2009, 07:28

Gosh - handcrafted electronics - its a while since I have seen any of that. Looks quite simple to build as long as you can get the bits. Please let me know if you need any help - I was once an electronics engineer in the days when a chip was something you ate out of newspaper and 28k of memory was HUGE...

GreatOldOne · #54 15th January 2009, 13:42

Thanks for the offer, Robin.

I stumbled across another cuircuit. This one is very involved!

GreatOldOne · #55 15th January 2009, 13:47

According to ETB:

http://www.etbinstruments.com/FAQ_Gauges.htm#Q1

Quote:

This sensor is calibrated to provide an electrical resistance of 260 Ohms at empty and 20 Ohms at full.

Isn't there a "simple" way to turn a light on when the sender is registering 230 Ohms (approx an 8th of a tank left, which would be about a gallon IIRC on a sportster tank)?

limpabit · #56 15th January 2009, 14:07

I found this while looking about.

http://users.telenet.be/miata/english/misc/lowfuel.htm

Adjustable as well.

MartinClan · #57 16th January 2009, 08:28

While we are on the subject of "extra warning lights" has anyone come across a DIY shift change light? Very useful when you are using an aftermarket rev-counter with no red line. I know you can buy them from the various speed shops but they start at around £80 which seems a tad expensive.

Robin

Patrick · #58 16th January 2009, 08:39

Not seen a DIY one, only the £80 ones

The staged ones look pretty cool that show a build up as you get near the limiter.

I'm going to be putting Megasquirt in mine soon and I'll use one of the outputs as a shift light.

limpabit · #59 16th January 2009, 09:19

I also noticed from Complete Kit car mag, you need warning lights for Main Beam, indictors (which you probably already knew about), but a new one on me is dipped beam warning for the IVA.
