Let's Make Robots!

Use an Arduino to get to the Moon

So, this whole Maker movement has got you excited, and the rocket you are building in your backyard is nearing completion.  But you haven't decided on a navigation computer yet.  You were thinking of using a laptop, but your daughter needs it for school.  Maybe a Beaglebone Black.  Darn!  Seems they are sold out everywhere.  You look around your lab, but all you can find is an Arduino. At first you pass right over it.  But when you can't find anything else, you start to wonder, "Could it get me to the moon?"

What every robot builder needs to know about

It is probably safe to say that every member of LMR is interested in machines that interact with their environment.  Interacting with the environment means getting information from it to provide feedback to the machine.  In the  electronics and computer worlds, "information" means "signals."  And since most of our robots use digital signals, whether with discrete logic chips or some sort of computer, and our machines need to do some sort of processing on those signals, we all need to be familiar with Digital Signal Processing (DSP). One note before we go on.

bdkdev 0.1.0 for windows released

My NXP LPC1114 downloader app version 0.1.0a has finally been released.  Right now only the Windows installer is available. The same executable will run on Linux with the mono runtime installed.  The files from the install directory can be copied to a Linux machine after it is installed on Windows if you want to try that.

UPDATE:   The raw Linux files are also available at that same link.  They may also work on a Mac with mono installed, but I have no way of trying that.  If anyone tries it, I would be interested in the results.

Filters (smooths) sensor or other data
This morning I was browsing LMR and ran across this post from janson .  In it he creates an averaging filter.  An averaging filter is a simple filter for … Read more

Any propellor you want, as long as it's black

Today, on the IRC channel, 6677 posted this link:

where Parallax has open-sourced the Verilog code for their propellor chip.  This could be very interesting.

LPC dev tools first release

Some of you are aware of my ongoing project to develop a good toolchain for the NXP LPC1114 and related processors.  I have finally posted an initial release of what I have so far.  It is really rough, but mostly works.  If you are interested in getting a head start or if you just want to take a look at what I'm doing, the files are here:

Feedback is welcome.  Please don't tell me "your documentation sucks," I already know that :-)
