Hmmm, 10 sales in one minute, equals 600 sales per hour, equals 10000 sales per day, roughly. MisterGreen will be busy for a few days!

Thanx, no more PAR level guess work in my tanks

I had my bullet preloaded in the gun and finger was on the trigger since 1400 and I still barely got in on the deal.

I guess I shouldn't have gone biking tonight, I guess I'll try to get in on the next batch.

Always curious.

1 minute- That's got to be record for the S&S. Unbelievable! I hope MIsterGreen has some more diodes and paint bottles laying around, that way he can get a head start on the next batch. I intend to start soldering the next batch this week end and hopefully blow out another 20 units.

OH man, You guys know how long it took me to make the first batch. I still have plenty of diodes but will have to find other components.

Calibrating is super easy. I just finished an hour ago and now to get some usps priority boxes

Well I missed out on the first batch! I have been following this for several months in the background to see if it would really come to be and it did. Congratulation! Now to my point, I am on the BOD of the Dallas/Fort Worth Marine Aquarium Society and we are always looking for presentors for our monthly meetings. I was wondering if mistergreen would be interested in putting together a 40 minute powerpoint presentation on this operation for presentation at one of our monthly meeting in the not to distant future? We are a salty group but we like light too. If you are interested, respond here. I will check back.

It's too bad that "life" always gets in the way of having fun. Bills, relationships, and other commitments have to be taken care of first and often. That leaves little time for other pursuits- other than sleep.
Should we try to find another way to create the sensor that is less labor intensive? - if there is one? Should we use something "off the shelf"? Any solution that would free-up Mistergreen's time to simply solder a few connections and calibrate the units would be appreciated.
I can build each unit in as little time as 15 minutes, but I have to stay up late to do so. I'm limited to a few hours on weekends to do the work, so progress will be slow- but I'll continue building these if the demand is there.

Well, not having to solder in the male barrel jack will save a lot of time. I'm not sure if there's any 'off the self' solution.

I'm going to run out of the 1/4" ethernet cord soon. Home depot stopped selling them by the roll. Do you know of a better solution? It'll be cheaper by the roll.

Electrical wholesalers would probably be cheaper than HD or lowes. I'm sure teu could cut you a few dozen meters of wire at a time.

We only need a 2 conductor cable with round insulation correct? I found this - seems kinda pricey though @ $45 for a 100' roll?

I'll take a look at my local electrical supply houses and see what they've got. I'm sure that I could find some more Ethernet cable for cheap, but shipping it to you would negate any cost savings.

yup, 1/4" in diameter. Yeah, I'm looking local to save on those shipping cost. I'll look around for a local electrical supply co.

I'd have to go get a decent soldering iron (been meaning to for a while), but I can do soldering if you send me the parts.

Always curious.
