Let's Make Robots!

Jaimi`s giant robot commercialised?

Seems like the spider walker mechanism inside the giant robot has been put into production. I`d love to get one to tear apart!

VB programming help wanted! Plotting serial data.

Hi guys, I`m attempting my own low speed arduino oscilloscope but have hit a brick wall with my mediocre programming skills. The arduino program and input stage works fine, it`s the PC software thats killing me.

Incredible wooden mechanical machines video

Have a look at the engineering that has gone into some of these machines. I especially like the gearbox mechanism on the 2nd video to change from raising to extending the arm.

step-up or joule thief or.. ?

I`m trying to convert the wireless doorbell outside from battery to a renewable source such as solar or wind. My problem lies in that the battery required is a 9v.

My first thought was to produce a high enough voltage to charge the 9v but that might require more solar panels than I have. The 2nd idea was to use a lower voltage battery or super-cap as replacement and stepping up the voltage to 9v. I haven`t taken any measurements of current usage but I don`t imagine it could be more than a couple hundred mA while pushing the button and much lower in idle.

SparkFun vs SPARC. Trademark infringement or rabid lawyers?

Everyones favourite supplier of robot goodies receives a cease and desist letter from SPARC over trademark infringement. Read the whole thing here.

SPARC really have no idea do they? If you have ever ordered goods from SparkFun before and wouldn`t like to see them forced to change their name by a big company send a quick email to sparcinfo@sparc.org saying what you think of this. Don`t forget, be polite, we are all adults.

My XK1 arrived this morning via Japan post. Being so close to Hong Kong I might be the first :P But they were sent out on the 9th so those people waiting on one should go check your post box!

Hondas new balancing personal transport.

Apparently its insides is a big secret but if you look closely you can see the machine actually moving sideways as it keeps balance.

I don`t know about you guys but as soon as I saw it I wanted to pull it apart to find out how it works, or at least turn it upside down and take a look at the bottom.

Vacuum forming plastic parts.

Heres a few photos of my home made plastic vacuum former and its maiden test. If you don`t know what vacuum forming is check here, and youtube.

Essentially a sheet of heated plastic is placed over some kind of mould which then has the air sucked out from underneath it. The soft plastic schloops to the shape of the mould and when it cools you have yourself a robot part. It really does sound like schloop if you`re wondering.
