28m underwater test, to check the network connection to the ROV

Here a video of today's test to 28meters, to check if the network connection to the ROV is really water proof

Build a brassier fly trap

I'm working on a steampunk inspired brass animatronic venus fly trap. I will call her Venux. Venux's robot page is posted, but there is more info in this blog.

CTC I am in the Make it Tweet Contest

Just thought I would drop a link...

I finally got around to Instructable'ing my Glen the Stove/ Twitter project. As it is, I needed to do so to enter in the Make it Tweet Contest. I did and I am.

Here is the linky-link.

avr-size is quite a useful tool...

I was pulling my hairs out over unexplainable crashes yesterday, occuring on a Motoruino board.

It occured after simply enabling some more debugging stuff and it started to act all weird: crashing randomly and corrupted serial data.

It really had me going nuts at some point -- even wondering if the chip was bad. All until I read some interesting stuff about the .bss and .data size having limits. A shame that the  Arduino IDE does not check for the allowed sizes for SRAM.

The following command can easily reveal my problem:

Nothing much to describe about this robot.Its a simple line follower robot which uses 2 ldrs Read more

3 new projects

I have started 3 new projects. I mainly wanted to use the laser cutter at school before the school year was over. So I made these things which I will be fully constructing in the upcoming weeks. I just threw stuff together for some photos.

My custom controller v2:

Cutting Acrylic sheet

I've been asked how to cut acrylic with a hot wire cutter - I made my own and there are a few plans for how to do this on instructables etc. This was my take on the idea which I find works OK for me... - see the file attached
