02:58 pm - "Unidose" chemical feeder pump
Purchased a chemical feed pump to help correct the pH of my well water. This is done by injecting a small (and precise) amount of basic chemical into the pressure tank while the well pump is operating. For the pH correct to be correct - the well pump and chemical feed pump need to pump at the same ratio. I estimate that I need a 1:1000 injection ration of a ~10% solution of "soda ash".
The Unidose chemical feed pump is offered as such a pump - and at the best price. Unfortunately, it doesn't meet the requirements. My first test (a very crude one) found that a few feet of head resulted in a very different amount of fluid per pulse. I contacted the manufacture (LMI) who interestingly couldn't give me any useful information on the change in flow per change in pressure. This is a VERY standard item for pumps! Even told me that it was so application specific that they leave it to the distributors to provide this information.
My world of electronics has similar types of components. They're called voltage regulators (or current sources.) Everyone one clearly states the change in voltage various changes in load. They due this as its critical to the function of the circuit to know the regulators performance. Injecting chemicals into drinking water has the same requirements!
Contacted my distributor that in short said, I've been doing this for 20 years and I've never been asked this question! Of course, he couldn't tell me anything specific other than "it works in this application". Wow - I'm injecting potentiality hazardous chemical into our house water and I'm supposed to take his word in this? What testing have you done? What follow up have you done? Sorry dude this is a terribly pathetic answer - its my family that will be harmed.
I always find it interesting how when one ventures into the skilled trades field (and not having been formally trained in this area) - they seem to think you're an idiot when you do something outside the normal process.
As my original experiment was crude (a "chicken test" - poor chickens) - I performed a better one. Basically measured the amount of water removed from my bucket after injecting the water into a tube a various pressures for a known time.
10 psi - 2.96 oz/min
15 psi - 2.95 oz/min
20 psi - 2.8 oz / min
25 psi - 2.7 oz / min
60 psi - 2.3 oz / min
There's a 25% difference!
Fortunately for me - the distributor will take it back. But I'll be out shipping two ways.

Far to often while I'm trying to concentrate on a winding road, the panel flashes that my wheels are slipping. There's a light related to RPMs, the door being ajar and that the fuel is low (its all on the side of the tank!). Then there's this annoying beeper that forces me to take my eyes off the road and fasten the seat belt behind me as I need to be able to move freely side to side to remain vertical. To top it off, there's this power hungry check engine light that causes the car to de-accelerate and activates some annoying attention grabbing mechanism that vibrates the whole car.

12:52 pm - so angry im trembling.
Was curious to see what FTL upto these days - and then I opened a Pandora's box of government abuse.
First there is the case of Sam Dobson in Keene. Sam is a reporter that detained in the lobby of a Keene courtroom - and is now held for 2+ weeks for taking the 5th.
FTL has a phone interview with Sam:
Then there's the video of the (semi drunk) naked man at some arts festiable.
Last week I watched an episode of 24 where Jack Bower used a Taser on a prisoner, and he was arrested for use of torture ...

A new level of tied.... I took the long way to work (yes Sunday afternoon). First I head out to Waldon pond, then go north/east on 62 until it hooks up with 3A. This takes me to mystic lake / Arlington and then onto Cambridge. Its only 41 miles - but I guess I rode hard.

Last summer I stopped carrying my out of state driver's license that expired in 2004. Despite the expiration date - it continued to serve a useful purpose every except the road.
Over the past few months I've been getting out to the kinds of places need proof of age to enter. Do you know I'm ~40 (I guess I look like (ack) I'm in my 20s still.) Fortunately, most of these places either just let me in when I appeal to reason or showed them a patient ID for Mass General that has my DOB.
Yet Saturday I tried to buy wine - and two credit cards, a MGH and two photo IDs wouldn't do it. The attendant pointed out that we have to run your bar codes though the machine.
I think its time for me to make own ID. I think I'll be from DPRK.

03:57 pm - But Who Was Right – Rudy or Ron?
Buchanan much to my surprise has an interesting essay over at antiwar.com.
"Ron Paul is no TV debater. But up on that stage in Columbia, he was speaking intolerable truths. Understandably, Republicans do not want him back, telling the country how the party blundered into this misbegotten war.
By all means, throw out of the debate the only man who was right from the beginning on Iraq."
A few weeks ago Justin Raimondo wrote this:
Ron Paul's Goldwater Moment : He's a Republican, he's antiwar – and the Establishment is deathly afraid of him
Hopefully enough people will hear Paul's message before elements of the major media destroy him....

12:30 pm - interval training
SOME gymgoers are tortoises. They prefer to take their sweet time, leisurely pedaling or ambling along on a treadmill. Others are hares, impatiently racing through miles at high intensity.
Each approach offers similar health benefits: lower risk of heart disease, protection against Type 2 diabetes, and weight loss.
But new findings suggest that for at least one workout a week it pays to be both tortoise and hare — alternating short bursts of high-intensity exercise with easy-does-it recovery.

Slashdot linked to a story about how 'global warming' is also occurring on Mars.
Its only a matter of time until man is blamed for this to!
