Numato Labs - One stop for FPGA Development boards/Expansion modules

We have been searching for a platform where we could buy reliable FPGA development boards and finally one day we saw a board in www.numatolabs.com. Without second thought we ordered one board which is suitable for us. We received the board today and till now the response from Numato was exceptional.

Advantages of using boards from Numato:

1. Exceptional support

2. Good technical information regarding the board in the site

3. Chance to raise queries using help@numato.com 

4. Quick and flawless delivery

5. Good follow-up

If we share this information in our blog or share via facebook, we are eligible for a lucky draw. More than trying to win a lucky draw it is everyone's duty to share information which is helpful.

Note: We have been trying very hard to find a vendor who can give reliable evaluation boards and we found one. Thanks Numato!!!

Circuit Debugging - Tip 1

Let us start learning some of the debugging techniques. Very common component used in electronics is DIODE. Sometimes, by mistake we tend to connect diode in reverse. So, before, mounting a diode the first thing we have to check is the ANODE and CATHODE. The below symbol indicates the polarities and corresponding representation.

If you still have doubt on the polarity, you can check using multimeter. The below figures shows the same:

Why use Aluminium for mechanicals?

Have you come across mechanical designs for your projects, then definitely you know that aluminium is the most preferred material for such. There are various reasons  for using aluminium and have a glance at the list below:

• Good thermal conductor
• Good electrical conductor
• Can be shaped easily as per requirement
• Weighs less, density (mass per volume) is less
• Durable, soft
• Resist corrosion
• Non-magnetic
• Aluminium is the most abundant metal of all.
• Gets less affected by environment factors like air and water
• Doesn't effect the environment, can be recycled
• Less chances of ignition

The conductivity of Aluminium is 50% of copper but still used widely because of cost factor compared to copper.

Very familiar Applications:

• Have you seen light poles in your area, they are made of aluminium
• Electrical grid lines
• Your kitchen cooking utensils
• Heat sinks for electronic components and mother boards
• Bus/car/Rail/Aircraft bodies are made of aluminium
• Railway tracks
• Cool drink tins

Note: Aluminium may not be used directly in any application and it is compounds (aluminium + other metals) that are used.
