With this in mind and a bit of time over I decided to sacrifice a laptop with a damage screen and see if it could be recovered after having a glass of wine and one of lemonade poured over it.

So, was it a sacrifice in the end? Have a look at the article which also includes a video (god, I’m a director all of a sudden) of how it was done.

First my apologies to all people who come back here day after day and wonder why there’s no action on Grynx. Well, try working 10 hours a day, studying for your MCSE every evening and then take care of your family as well. I’m simply not allowed into my garage any more
Hopefully this will change in the next coming months - but I make no promises.

In September 2007 I published an little application of mine called Greylist. At that stage Greylist was a bit unpolished and rough but it did evolve during the next coming months whenever I could stick a bit of time into it.

Today I published v1.3 which now is more of a grownup and handles both stress and problems in a more correct way.
Some interesting statistics about the artice: Over 8500 people has read the article in the last three months and it has been downloaded over 1500 since end November.
Not bad for me that didn’t have a clue about programming 6 months ago. Pat Pat on my own back

Since I have had a lot of problems with false positives with the black lists that I’m using on my Exchange 2003 server I started looking into another way of filtering spam…
The problem with this is that there doesn’t seem to be any free products out there for Exchange and as I don’t want to set up a Linux box ( yet another box in the rack ) I decided to write one myself…

Features of today includes selective blocking (sender ip and/or sender address and/or recipient address), stores data in a access db or in MS SQL, the database can be shared across the enterprise, automatic pruning. In the latest version I added functionality for different actions upon grey listing a recipient as well as custom server messages.
And in many scenarios it block up to 98% of all spam!!

If you’ve read this far and don’t have a clue about what I’m talking about then let me say this:
- Grey listing temporarily blocks an email in an attempt to filter out spam servers.
- Greylist (the program I wrote) only runs on Exchange 2000 and 2003.

If you’re an Exchange admin and you have problems with spam then be sure to check out my implementation Greylist - freeware Grey list for Exchange

OK, everyone has seen the dude who made an LED POV (persistence of vision) clock out of a hard drive, and we’re all very impressed (no, seriously). But not all of us have those skills. This is a hard drive clock that requires only a power drill and some basic hand tools. No electronics knowledge is necessary. Total project time: 60-90 minutes.

I think this one is interesting as you can actually see that it’s a hard drive. The one I made had a different goal though - to only have hard drive parts visible.
Anyway - I like’em both.

With the addition of one capacitor, one relay, and a small piece of wire we can convert an inexpensive wireless doorbell into a remotely controlled relay useful for a wide range of applications. These include remote PC starting, lighting control, Halloween effects control, or virtually anything that can be controlled by a pair of relay contacts.

And here’s some food for thought for you DIY’ers. How about taking one of those cute small radio controll cars and turn it into a dimmer control? The benefit of using these small cars as a build base would be that the rf reciever cards are very very small.

On this page i will explain how i created my own colour changing lamp with red, green and blue leds that fades between all colours of the rainbow. It really comes out well at night when other light are dimmed. In daylight conditions the colors aren’t noticed well. Although it’s low budget i must say the result is nice.

Greylist is simply a greylist program for Exchange 2003 ( should work on 2000 ) which will delay incoming mail for a couple of minutes. In my environment it blocks 98% of all spam and so far it hasn’t blocked a single ‘good’ email.
And as I like the whole idea of open source, I’m publishing it just like that - for free. Or rather freeware.

I wrote this as I couldn’t find any free grey list programs out there. Lots and lots for free for Linux, but only commercial products for Exchange.

Non electric hacks Other http://www.Grynx.com/2006/07/02/binder-clips-and-cables/ How about making without making??

This is such a thing which actually isn’t a project in itself - but if it will give you a tenth as much help as its given me in the past years then it’s something I just have to share with you.

In short - attach your cables in a smart way with an ordinary office supply and keep them movable/slidable.

Take it or leave it, this is a great project that involves few components and has a compact and robust design.
