We take good old O2 for granted. People are always going on about how early Earth was “perfect” for life. A perfect hell maybe. No ozone layer, no oxygen, extreme heat, an abundance of highly corrosive chemicals in the atmosphere including sulfur and methane.
Much like found on Titan the largest of the moons of Jupiter today. It was a literal red sky hell. With all of that methane and sulfur, it must have smelled like a frat house on chili and hard boiled egg night. So, the Earth was devoid of oxygen in the beginning but as I said there was a metric butt-load of methane and sulfur in the oceans.
So, little single-celled organisms developed that lived on methane and sulfur. After a while, the sulfur level dropped and the methane level did as well. No one is sure why. There still was little oxygen. So some more little critters evolved which produced oxygen called “cyanobacteria”.
It took a billion years for these critters to terraform our planet for the evolution of animals and more complex plants. To this day all plants incorporate these ancient cyanobacteria into their cells in structures known as a “cyanoplasts”. You see life itself changed the planet to support life.
This is what life does.

it seems the nature of this tube. I’ve been using a few Bendix 5y3gt with Fender tweed amps. and it’s my first try with their 6v6gt.
Grasshopper’s Dream is an insect-shaped cafe that sits along the popular Auraji rail bike route near Jeongseon, South Korea. The converted and stacked green train cars are placed near by the Gujeol-ri train station, and are each outfitted with protruding metal legs and thin antennae.

my ’94 yz10 runner got a new shell with some decals today.
now it runs with
HD universal drives
Yokomo Aluminum motor mount
Team Suzuki F/R hubs and hub carriers
’93 WCS steering
[update from July 2nd, 2015]
found the MX4 wheel hubs for YZ10. and more MX4 wheels for this setup too.
pargu is working on the wheel hubs. you guys can use them pretty soon.
sometimes, words are like the windows through the history and culture. now I see why we keep seeing the white witches and wizards who are the symbols of wisdom on the movies. and why we have the similar names from the western culture.
I have emailed to dozens of electric part suppliers and messaged to ebay sellers for
and I noticed most of them are counterfeit. this seller looked legit with the picture of NOS Siemens relay. but it didn’t go well.
and it’s the the relays I got from this seller
The original Siemens, Tyco, TE connectivity relays have molded bottom with thick and strong lead pins. and, you can buy this counterfeit relay on alibaba.com or aliexpress.com for less $1 each
I’m talking to these two sellers for the original part. and one of them are running this web site
I do trust this guy and made a purchase from his ebay store
also this seller has the original relay. but it’s V23084-C2002-A403
the only difference between A303 and A403 is the contact material. and C2002 is sensitive type works with less current as far as I know. I’ll try them both and will update
another seller sent me this picture. and it’s exactly the relay I’m after. you can see the pattern on the bottom but even many of the counterfeit have the patterns as well. but please see the pins carefully all the soldering pins are thick and look strong enough.
I’m ordering a pair from this seller who sent me the picture
it took a couple of months to figure out which is the original and finally found these 2 sellers which I trust on ebay.
I’ll update when they arrive
and please someone advice me if V23084-C2001-A303 can be replaced with
V23084-C2002-A403, or V23084-C2001-A403
I’m running this small version of Buggy Champ – Rough Rider for years. yes, it’s small and cannot run on the bumpy tracks.
and I watched it’s not bad on the the rally circuit where I’m running my old RC10 and 834B runners.
this tamtech champ came with the plastic spring dampers. buggy champ runs like tamiya grasshopper with the stock shocks. actually it runs better than grasshopper.
google found me Losi Mini-T shocks weeks or months ago. an I’m running with the shocks. losi shocks turned this tiny champ into a racer.
