Let's Make Robots!
Encouraged by a comment to RobotFreak's rendition of a SpurtBot, I am trying to build one too. I hope to make it as cheap as possible, because the goal it to bring … Read more

NiZn 1.6V rechargeable batteries

I was at a gem and mineral show today and ran across a rechargeable battery technology I had never heard of before. The NiZn 1.6V batteries are fairly new, though they've been around longer than I would have suspected.

At 1.6V these AA and AA batteries are a lot closer to the voltage of the equivalent 1.5V alkaline. The vendor whose table I saw them at uses them for his UV light (used for examining fluorecing minerals). These lights won't run with 1.2V NiCad or NiMh, but they work just fine with the 1.6V NiZn batteries.

Would an LMR Marketplace work?

This past weekend I thought a lot about a separate entity that would run the commercial side of LMR. Very like how Adafruit.com represents a company,and Ladyada.com is a supporting community site.

I have an idea for an LMR Marketplace that I think would allow a commercial side to LMR, that stays true to the spirit of LMR.

What's ignoblegnome building?

Any guesses what I am building? Sound like a fun game to play?

I am anxious to hear your guesses.


Update: An easier way. 

TheAndroidMan posted a tip/walkthrough on adding pnuematics to a robot. That will make this project much easier.


Update: The answer!

LMR Member Discounts

Frits has negotiated discounts with a number of web shops. These discount deals are for LMR members only. Info on these deals is shown at the very bottom of the main page. I'm not going to list them here, as that is just duplication of effort.

However, a few shops have spontaneously started offering discounts for LMR members! You guys rock!

This post is my attempt to collect a list of them.

Telepresence Robot... by Saturday

Err. Does anyone have a telepresence robot they could lend to a good cause for a few days? 

Oh, and it needs to get to NYC by Saturday. Yes, this Saturday.

No? Oh, well. Worth asking.

Heahter Knight, all around amazing human, robot expert and one of the key organizers of the first ever Robot Film Fest just sent out a tweet asking to borrow a telepresence robot for this Saturday at the fest.

Man I would love to go to that event. I would love even more to show up and help deliver something for the event. 

OK, OK. Longshot.
