Logs data....what else would it do!!!
This is one of the latest projects that I've been working on. The idea was simple and in a way came from the desire to design something similar to the … Read more

Second set of eye's on a sn754410 driver setup

wired up

 

Note green LED(yes it's set up in the correct orientation and even when I hook up a vmeter I don't see a voltage) is not lit up.(red is power indicator) I feel like amature hour here with this simple circuit yet can't seem to get it to work. Tried 2 different chips. Recommendations are welcome...I only spent this morning looking at it....

Provides a 16 port IO device for the chip.
A note on the cost and time estimates. Time = time to draw out the schematic, do the layout and then populate the board. It's also the little things that seem to be … Read more
Allows you to save data to off chip memory location as well as record rtc data.
This is a early LP shield that was actualy meant to have other features, but due to time constraints and wanting to get something to test with, I had to cut out a … Read more
Moisture sensor for your garden...so it measures moisture...
Headphone plug turned moisture sensor. For a little while now I've been looking at how to do a diy moisture sensor that I could use for my garden project. There … Read more

Google plus hangout Saturady afternoon 3pm PST.

Heya LMR folks,

I'm thinking of having a G+ hangout session tomorrow around 10am pst(I'm in California), 1pm est, UTC -7(I think).

If you want a gmail invite, send me a request by 9:45am and I'll send in invite your way and have a gmail account I can send it to.

I was thinking of just shooting the breeze, talking about bots, projects, and just general stuff.

maybe it'll be something, maybe it'll be just me some ambient noise....we'll see!  :)

 

Edit: modified time.

Provides regulated power and battery backup for low power systems.
The powerboard is part of a gardening project I've been working on that uses low power systems and integrates with a solar panel and battery backup. The intent was … Read more

Capacitive touch board for TI Launchpad MSP430

http://e2e.ti.com/group/msp430launchpad/b/boosterpacks/archive/2011/04/17/430boost_2d00_sense1.aspx

Just a note that this is a pretty sweet device and worth it for the price. Hell, the launchpad alone is worth the price considering it's utiility and fun aspect. I picked up two of these and just played around with the default app, when I have more time, hoping to make it useful and do stuff(control motor speed or something like that.)

 

How to use HPWM for picaxe chips.

This information is based on the chip that is used for the 20x2(PIC18F14K22) To get a better understanding of the modes, I suggest referencing this datasheet for further information on the chips features. IMages and info are referenced from both the picaxe 2 manual and the PIC datasheet for the above mentioned chip.

HPWM, what is it?
