Rex + Wheel Hybrid

Thought MarkusB and others would appreciate this.

I made a Simple controller for this arm. The controller is based on the Wilde thumper controller from DAGU. It is Arduino based controller with ATMEGA168. For more … Read more

Picaxe 28 circiut board robot

I am trying to make the robot in the start here section.  The motors work when I hold the wires to batteries but when I try to attach them to the board they don't work.  I have followed the instructions carefully and soldered the wires to the pins (as I don't have connecters).  I have tried several times and am still stuck.  This robot is for a school project and has to be ready in two days.  I really don't know what to do can anyone help?

Thanks

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

This is my latest FireFly codename Megan40 ...... because she sports 40MΩ feedback resistors

If you need detectors that are not affected by ambient light then i highly recommend using UltraViolet LEDs as detectors.

The detect circuitry is finished - next part is to shoehorn the picaxe 08 onto the back to control servo and UV glowtube.

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.

Getting angry about the availability of electronic components in Europe?

Hi there,

it has been a while and I am still working on the stereoscopic vision issue for my small robot. Meanwhile I learnt, that the Parallax Propeller chip is by far to slow to handle and stream-edit an BT.656 conforming digital video stream, at least for what I have in mind. Therefore I am now working on a hardware-based video filter made of discrete components - a poor man's FPGA, so to say.

Motor Driver for 4 wheels

Hi friends,

First post. I have a quick question. All I am looking for is a motor controller to control 4 wheels. I thought of putting together 2 L293D ic's, but asking your help to suggest other IC's which can reduce a couple of pins. Also the current requirement is too high in L293 IC's.

If someone has experimented with other motor drivers (commonly available) and suggest me, that would be helpful.

 

Requirement:

Control: To control 4 motors

Voltage: Should work between 5-12 Volts

Please let me know if you need additional inputs.
