Slug is the American unit of mass. I looked up the Hubble telescope issue because I though an underlying part of it was the use of those parts to build a couple of spy satellites. It was mentioned there was a problem of units, but it wasn't really a conversion issue. As David Redszus says that just ...

This is a huge subject. Do you have some idea of the type of parts you're talking about? You can CNC mill or route foam panels and stack them into a body or some item's ( intake manifold? ) shape to make a plug which you "splash" a mold on with fiberglass to make a female mold. Depending o...

Could you use gas from a MIG welder? Or even a Helium ballon? You'd need to make something simple to enclose the unit and then purge it.

Proper signal connections are "gas tight", and that includes water vapor. Water molecules are much smaller than air molecules and have their own difficulties. Soldering achieves this well because the solder dissolves a bit of copper and alloys at the boundary. If you do much of this at all...

If I turned the one shot time short enough to freeze the motion acceptably, the light was so dim that it was of no use. A xenon strobe light can discharge a lot of joules in a very short time. Well, I think that's the issue. Still the ones on cars are pretty bright and clearly visible on a sunny da...

Thanks Rick. I don't think my laptop has those anymore, but I'll go read that - I'm sure I'll learn something. I did go look at some spec sheets and this seems doable still. For about $1 you can buy a chip with two timers on it. The spec sheet says 0.1 micro second propagation delay and 0.025 uSec r...

I had the idea because I thought it looked like the accurate timing light you showed a photo of used LED's for it's light. If there is an issue with the time it takes to get the LED to turn on, we can keep it turned on at a minimum value and then greatly increase the current when it is supposed to m...

I had to look this up because I didn't know wether altitude made a clock run faster or slower. I thought slower because it would be moving faster, but gravity is more important it seems so it runs faster. These clock are now way more accurate than the crappy old regular atomic clock from the 70's. I...

is auto-synched to an atomic clock in Boulder CO

Geez, I don't see how a clock in Boulder is going to work for you Bill, can it automatically add leap femto seconds for you? Or is time slower in Canada?

Kowa Seiki KE-50-7 “Synchro Beam” timing light is by far the best I have ever used. Small, pocket sized, two AA batteries, brightest ever, brighter than 12V powered lights. They are the most accurate light I know of because they have the least lag between the spark pulse trigger and light flash. An...

Think about it the cylinder fires every other revolution even at 10,000rpm that's only 83hz. I wrote a long reply yesterday but when I started to think about I was surprised at the amount of delay it would take to produce this error. As the original poster said it would be about one half millisecon...

Wire in a push button ( maybe the horn button is available? ) and give it a push just as you use the kick starter...

The blueing happens a certain temperature. It would be nice to have a before picture too. It looks like maybe it used to be blue on the pipe for the first 12" or so, you can see a change just after that. When he did the run he may have heated the earlier part of the pipe up enough to remove the...

That's the thing, things are pretty much blue sky when you get into computers and especially software. For example, do the rules prohibit other computers in the car? You can have another ECU sitting there that is connected to the engine and it's job is to feed the Holley ECU whatever it thinks it ne...

That there is a great example of GIGO It's prbably about right if it was on a flowbench with all ports open together. Not on an engine though. It's not garbage in, garbage out. You just have an excessively simple way of looking at things combined with a need to be condescending. Did you read the pa...
