CircuitLab.com is a cool web-based “workbench” where you can create circuits and simulate it.  You can do DC analysis, Time Domain, Frequency Domain analysis. I think it’s a great learning tool to “experiment” with circuits and see what will happen.  No special software need to be installed, you can run it on your web browser. I’m using Chrome browser in this example.

For example, shown below is a simplified circuit of the mid-frequencies of an LC based equalizer.  To keep things simple, we’re using 10K resistors, 10K potentiometer (represented by R4/R5) and a 0.1uf, 100mH and 1K resistors for the RLC component of our filter circuit.

I’ve implemented multiple quantity discount when you place your order for our different items/FAB Modules.

So in summary, you can save a lot by taking advantage of the following:
1. Buying multiple items
2. Earning Reward Points (when you buy items) and redeeming them during your next checkout for $$$ savings
3. Using Discount Coupons

Today, I got the “coupon” feature working on the FABModules Online Store.  We’ll have varying amounts for the coupons… either a fixed percentage, or a fixed dollar amount applied to your total order. How sweet is that!

These coupons will be posted on Social Media sites like Facebook, Twitter, etc….  just grab the coupon and visit our site for instant savings! As you can see from the screenshot, use of Reward Points and FAB Coupons could bring big savings.

I’ll be using OpenCart for the upcoming FABModules Online Store and I’m thinking of trying this Reward Points system to well, reward  my faithful customers!

Basically, you earn Reward Points for every item you buy from the online store. These points accumulate in your User Account (you must be a registered user and not use the Guest Checkout). You can use these earned points as real money “credit” on your next order.

I’ve successfully setup a Wiki for the FABModules website.  It can be found by going to FABModules.com/docs.

The Wiki will be used to store all documentation, tips, techniques, application notes, schematics, diagrams, photos, PDF and Zip files for all FABs.

I’ve decided on using a Wiki instead of the WordPress database for easier maintenance, and more flexibility. It’s also much faster vs. WordPress since all the files are stored as “flat files” in PmWiki, the PHP-based software platform I’m using.

I’m going to try to build the “skeleton” and “framework” for the Wiki page, and populate it with preliminary information. Then I’ll open the wiki to the public so they can add their own stuff and content as we continue to grow.

All Edit access to the Wiki will be “password-protected” but the password will be publicly provided on the Wiki welcome page. I did this to minimize the wiki being spammed by robots, if I just simply provided open access. My thinking is people who are interested will be reading the Welcome page and find the password they need to edit pages.
