My bluetooth on my laptop will have trouble establishing a connection sometimes. The only way to resolve it is to turn my WIFI off and then back on again. (Cycle the power to the WIFI which also powers the bluetooth)... Then it starts working.

I'm not sure what it does that, it just does.

Is there a warranty on the EZ-B and if so, what is the time period?

There are no moving parts for the ez-b. And it is an exposed hobbyist/expiremental circuit board puts us in a very difficult position to offer a customer warranty. No companies that are in our industry provide a warranty of a product that was used.

There is a memory location stored on the chip that keeps statistical information about the use of the EZ-B. Helps us know what the board was used for before it broke. Also tells us that it was indeed working if someone tries to say otherwise.

If you received it and it worked but stopped working, then we'd have to assume it was damaged by mis-use. We can discuss the damage to the board for repair, however. Usually repair is a damaged I/C and that is something we can send you to do yourself.

We've had a few boards come to us that were damaged by mis-use that we have repaired for a fee. Because it is electrical, there is an internet of knowledge available to understand shorts, polarity, and our documentation specifies max voltage ranges.

What issues are you experiencing?

My Bluetooth Module disconnects after a short period of time. I then have great difficulty getting it to connect again.

Sounds like your bluetooth on the laptop. Do you have a switch to turn the WIFI on and off on your laptop? If so, cycle that switch for a few seconds and then back on again.

I have that happen quite often. When it disconnects, you may have to cycle the power on the EZ-B also. Not often, but sometimes you may.

Bluetooth is kind of silly. Sometimes it works, sometimes it doesn't. At least in windows anyway

If your module works once, it will always work. Electronics don't fail that way. Unless there is a loose solder connection. You can diagnose that easily by picking up the board and moving it around.

Also make sure your I/O isn't drawing TOO much current for the battery supply. The EZ-B has voltage regulators that will supply a lot of current, but only as much as the batteries have. So if you are using the 5 AA pack, then don't expect too much usage with many servos. My Wall-E only gets about 60 minutes with 5 AA's when it's full-on

Rechargable AA's are even worse for power. They supply less voltage, and usually the the same or less amps. Plus they generally wear out quickly after multiple recharges.

Don't confuse the bluetooth dropping with a faulty module

Thanks. I have been only using rechargeable batteries so I will make a change to the normal type. Hopefully I will be able to get back to building. The new ARC is brilliant by the way. One of my favourite additions is the Script Console. Also the ability to search the Forums and the Remember Me checkbox are also really useful additions to the website. Perhaps you could apply your programming skills in a really advanced occupation. I am sure they will need people like you.

Thanks Creativita That's really nice feedback. Words like that help fuel my passion for the project.

If you can provide me with a list of peripherals you have connected to your EZ-B when it fails, that might help diagnose the issue.

Hello there,

My name is Alon,

Im new here and in the great world of robotics.

I lookd at the EZ-B kit and it looks great.

Before i start i would like to know if the EZ-b would work on the 15 inch R2D2 from hasbro. its a voice command operated. Can i use EZ-B to improve it and make him otonomus and use the voice command and sound that the R2 have??

Have some one try this mode?

About me :

Im atoy collector, i have never workd with programing and robotics, and i would be happy to start my way in the robotics fan world.

DJ i love the work you did on Wall-E

Hope to mod my R2 unit

HAVE A GREAT DAY

Alon
