blog.autospeed.com
that better fits the dynamic of reader
interaction. The facility for reader contributed comments at the end of all
published articles will also be implemented in the future.

Failing Monitor
i have made and installed single led loop
monitors on two 97 miatas and they both work well for only a couple of days. i
am very sure of my connections. the ic's are damaged and when i replaced
the lm311 they both work again but again only for a couple of days. it seems
something's wrong with the circuit design. i hope you could help me on this.
thanks.

The circuit is the simplest possible and so it is
not protected against voltage spikes, etc. If you are continually having
problems we suggest that you instead build the Smart Mixture Meter and if required mount just
one of the orange display LEDs on the dashboard.
Diffs
I was just searching through the old issues and
couldn't find any articles about differentials and the types of traction
aiding devices available. This may be because I haven't used the google search
function correctly (I could not work out how to make it genre specific like the
old search function), if this is the case please let me know. Otherwise it might
be an idea to do an article on this, explaining the different types of LSD's
(viscous, mechanical, 1way, 1.5way ect.),locked diffs (mini spools, welded
diffs) and ratcheting diffs (lokka's ect.) How the devices work and more
importantly how the car behaves, both pro's and con's would be great. Also
an article on older cars with character (late 70's to late
80's) particularly the euro's might be something worth looking into,
dedicating an entire article to one of these cars might be pointless but maybe
having a 2 or 3 part series with old BMW's, Merc's, Alfa's, Jag's ect.

Test
Great to see back the new car
tests in all their informative prose. Would it be possible for the team to
do a test on a Toyota Aurion. Although I do not own this model, I think it is
the best family car ever produced for the Australian car market.
