I have previously written about Google Custom Search Engine (CSE) program. In a nutshell, this program allows you to use your expertise to help improve web search for specific subjects. Originally CSE could be only hosted on Google's website. Now Google lets you host a search box and the search results for your CSE on your own website which lets you add various enhancements (such as radio buttons) by modifying the script.
You can access my power electronics search engine at http://www.smps.us/smps-search.html . The HTML script for radio buttons is courtesy of Ed Schmidt http://www.lures.info/ .
I encourage you to give my custom search engine a try and compare your results with the results you are getting with a standard Google search. If you like this search engine you can add it to your Google homepage or to your website.

California RoHS law
OK, so you might think you are not selling your products in Europe and you don't have to worry about RoHS. Nah!
Beginning in January 1, 2007, a California law will ban the sale of some electronic devices if they are prohibited from sale in the EU because they contain certain toxic metals.
At present CA’s RoHS law will be similar to EU RoHS Directive, but narrower in the scope of affected products and the number of restricted metals.
Here are some highlights of the CA's RoHS law:

At present CA’s RoHS law will be similar to EU RoHS Directive, but narrower in the scope of affected products and the number of restricted metals.
Here are some highlights of the CA's RoHS law:
- It applies only to so called “covered electronic devices,” which are defined as video displays with >4" screen (such as CRTs, CRT and LCD TVs, computer monitors, laptop displays, plasma televisions).
- It does recognize all exemptions adopted by the EU.
- It restricts only four out of six substances (Lead, Mercury, Cadmium, and Hexavalent chromium) and does not restrict the use of PBBs and PBDEs. However, the use of flame retardants such as PBDEs is already banned under California Health and Safety Code since June 1, 2006.
Complete info is available at California Department of Toxic Substances Control. Also, you may want to get RoHS, WEEE and China RoHS manual as well as China RoHS EFUP guidelines translation.

Enhanced web searches for generators and power supplies
No matter how good Google search algorithm is, a purely mechanical algorithm can't always determine which sites are really useful and which are not. In addition, no search algorithm can know exactly what kind of info you are looking for. We all know that general purpose search engines bring up a lot of junk.
To address these issues Google recently launched Custom Search Engine (CSE) program which enables you to enhance your search by using human expertise and by specifying what type of info you are looking for. Particularly, my content is intented to improve your search experience in topics related to electrical generators and power electronics/SMPS.
EXAMPLES. Say, you want to choose a home generator and looking for something to start with. If you select my Guides/Reviews category, on the first search results page among other buyer's guides you will find a link to a very handy Consumer Reports' rating of generators. Otherwise, with a regular Google search this link is not among the top search results.
Alternatively, if you are looking for physical principles of electric generators you may want to eliminate commercial and advertising sites which represent more then half of the top results in "electric generator" query. Even if you try a more specific query like "how electric generator works", many relevant pages are still not at the top. Why? Because a search engine goes mainly by keywords you entered- obviously it does not know how generators work. Many web pages that describe in depth generator theory just do not use all these terms and won't show up in your top results. They do use more important terms though- you can't really describe generator's operation without using such words as Faraday, induction or magnet. That's why these terms are added to my "Generators/Physical principles" label. If you select this label, they will be automatically added in background to your query as additional search terms. This will make your refined search results more relevant and will weed out unrelated pages. In addition to this, web pages that I've personally reviewed and found useful for this topic will increase in importance within your refined search results and will be marked accordingly while spam sites and sites with unrelated or useless content will be pushed down in your custom search results.
You can do your search from my respective search engine page http://www.smps.us/smps-search.html or http://www.generators.smps.us/generators-search.html.
I encourage you to give it a try and see the difference for yourself. Note, this is a work in progress. I keep testing different keywords and algorithms to provide you with the most relevant search results. All comments are welcomed. To subscribe [by using any email address] click on this button:
