NBM Trade show

I went to the NBM trade show today with a friend. This is a trade show for: Sign business, awards & engraving & print wear.

This show was proof (as if any was needed) that our economy is way down. First off this show is normally tough to get around in because of the crowds but this time you could leisurely walk around without dodging people every 2 feet.

Secondly they put tables in the unsold space for people to sit and grab a snack, normally there are a few tables and many people end up standing to eat and many also end up sitting on the ground to rest their feet. This time they had about 20 tables with 4 to 5 chairs each and less than 25% of them were being used.

Yes I am saying the place was empty. Fewer exhibitors than I have ever seen and even fewer attendees. The good news is that the attendees that did go got the full attention of the sellers where in the past you had to fight your way to some of the booths to ask a question or two.

While the offerings were few I did find a few items of interest to myself. One company had some inexpensive (key word) super tiny LED's on a 3' string with a battery powered driver box on the end. The LED's were about the size of a cooked grain of rice and very bright, they had white and blue on display. With the driver box you could make then on steady, flash at several rates and fade in and out all for $15 a string. You can not get them longer but you can cut them shorter if needed and the wire is a dual white wire that reminds me of very old earphones that you could get for transistor radios (tiny).

Another product that I found of interest was some adhesive backed vinyl (sign vinyl) that is a little thick and is black... So what's the big deal, oh the face of it is a chalk board. Basically cut it and stick it on any solid surface and you have an instant chalk board, write on it with school chalk and wipe it off...

This same company also had white vinyl that makes an instant dry erase board. Not sure what these would be good for but I will try and think of something.

Zerowater filter pitcher

I recently bought a ZeroWater filter pitcher to hopefully replace the use of bottled water. They include a little device to measure the dissolved solids in the water as a measure of how good the water is.

They claim that the water out of the filter will read 000 to start (thus the product name). And they tell you to change it when you get a reading of 006.

Well after following the instructions to the letter our first batch read 004. In the manual they say if it does not read 000 to take it all apart clean it again and try again. I did, I was extremely thorough about it and still the result was 004.

But the water tasted good so we decided to ignore the reading. Well the love of the water was short lived, a week and a half into the new water and it started not tasting so good, by week 2 we could not drink it, it had a nasty sour or tangy taste to it, much worse than our tap water alone tastes.

So I took another reading and it was at 030, way beyond the 006 level they suggested to change the water at. How could this filter last less than 2 weeks?

Looking back on it the company never gave any hard rules as to how long the filters would last, they hinted at months and the commercials made you think it would last a long time but 2 weeks?

Well I put in a second filter and while the water tasted better again the reading was still not 000 it was closer at 002. I have emailed the company asking for any advice or explanation.

After getting the sour taste I did some searching and found a few people mention it and they both felt or found mold growing in the filter. Now our unit was always kept in the fridge when water was in it. I will wait to see what the company says and post it back here. For right now I would not recommend this system to people due to it's short life and at $14-$17 a filter it could be more expensive than bottled water.

Proper Soldering

I was prepared to write an article on proper soldering today. I was also going to take some photos to go along with it. But while I was researching the subject a little I found someone beat me to it and has the best soldering video and photos I have seen.

I have to hand it to him for covering the subject very thoroughly and giving clear and easy descriptions on soldering.

So instead of me re inventing the wheel I just decided to post a link to the site that already did it right.
