Let's Make Robots!

Connecting Arduino to Mac and PC, the easy way?

While working on an Arduino-start-here tutorial, I am trying to find the most "fail proof" way to hook up an Arduino.

Now, if I could decide what OS and connection everyone had, it would be easy as this:

* Install Ubuntu 10.10 OS on your PC
* Install The Arduino IDE (and write your program)
* Insert an USB-FTDI cable from conputer to Arduino board
* Select the serial port

- And done, you can now press the "upload"-icon, your program will compile and upload.

The above is so far the easiest I have found.

Does disabled persons pave way for robots?

Please note: English is my second language, I may involuntarily make fun of people without legs and or ears etc. This is not the intention, and I am sorry if it happens!

Because of this: http://letsmakerobots.com/node/24014#comment-58207

I just got to think: There are many places where the installations for disabled persons may have paved way for robots to do stuff.


Android LMR app ..?

Google has made it pretty easy to create apps for their Android OS, that I am sure you have heard about, and possibly use.

I am a heavy user, and I'd like to try and make an LMR app, just for the fun of it. Or have yours on my phone?

But what on earth would be fun or possibly even useful?

Perhaps it's  an all together stupid idea, because one can always just use the phones browser, and get "the real thing" there, even log in and all. Several of my posts have been made that way, from my phone.

Best Arduino (compatible) board?

I want to make the next generation of the "Start Here"-instructions be based on Arduino instead of Picaxe.

Some will say that it was about freakin time, but so far the advantage of the Picaxe has been that I could chose a single board that "did it all": Hook up Motors, Servos, sensors and everything.

This, and the fact that the Picaxe Basic Language needs very little introduction, made it the choise - even though the Arduino series has been a lot more popular recent years.

Why is it always late?

Question to the live show:

Why is it always getting late, when I am having fun?


What parts to use for the next LMR Start Here robot

As you may have seen in the LMR Live Show, we need a replacement for the Sharp sensor used in the Start HEre kit, as the sensor used till now is no longer being produced.

On http://letsmakerobots.com/node/22657 a lot of really new and interesting sensors came to my attention.

Now, since I am going to do a whole ned version anyway (we cant have instructions with images that doesnt match), I was wondering if there would be other parts that should also come in to the modern times?

New cheap sonsor for the Start Here robot?

The Sharp IR sensor that is used in the present "start here" is no longer being produced.

We need to find a replacement, and all ideas welcome.

Conditions: It must be a cheap distance sensor that can be purchased "in the shops".

Cheap, and commonly available.

Holder & charger for mobile LiPo batteries (Open letter to Jack / DAGU)

Since I had good luck last time (http://letsmakerobots.com/node/7046) - I will try again.

This time, it is batteries.

As I was just talking with Gareth about, it is a shame that all the used mobile phones get thrown away, with nice LiPo batteries, even chargers.

And you can get really cheap LiPo's if you get some that should be sold as spare batteries to common cel phone types, or outdated models.

What I would like, would be a HOLDER and second a CHARGER. This would open a world for us!



Meet LMR friends IRL

Over times there has been a lot of people wanting to meet up IRL. And there has been a few occations, and it has allways been fcking great times! Seriously! Days to remember, making good friends.

There is something REALLY cool about meeting for a beer, it is always worth it.

If only we did not live so far apart..

Unless some miracle happens, it is hard to arrange LMR-only-happenings cross globe. No matter how many members we are, a meeting can only attract that many people, and it will be hard to get togehter from several continents.
