Building a Better Bipolar Stepper Motor Driver

A stepper motor driver where a dsPIC33 both monitors the current and controls the PWM via an L298N.

A few years ago I started building stepper motor drivers. First it was a simple unipolar driver. My motors wouldn't rotate faster than 1 to 2 rps. So I … Read more

Make Your Own PICAXE USB Program Cable

By gecko

August 23, 2011

Hi everyone!

I was just wondering if anyone else has made their own PICAXE program transfer cable?

I had all the equipment to make one, 2.5mm stereo jack, colour coded wire, a usb plug and soldering equipment; so I thought i'd give it a go!

The connections for the PICAXE cable seemed very simple (having only Serial in, Serial Out and Ground) and knowing that a usb's connections were quite similar (Ground, Data+, Data- and Vcc) so I tried to match them up.

The most comprehensive searchable links-list for DIY/hobby/robotics

By HSPalm

June 13, 2011

Right now I don't have the time to transfer all the links from my site to LMR, but if it's not legal to link to another "links" site, just tell me.

The list of links are searchable by tags, gives you a price example of shipping costs and states wether or not the site accepts paypal. It is also tagged with origin country code, so you can sort by your preffered country.

Hoping to make the links-site some sort of a wiki, but I don't have the time to do it right now.

Best robot chassis

By jmorgan

April 26, 2011

Was wondering what you guys thought the best "chassis" for robot development was. Not looking for electronics or a "kit" but just a platform with wheels (or legs or whatever). I like the idea of doing my own electronics (processors, sensors, power systems, etc.) and could/would eventually build my own from component parts, but I like the speed of starting with known motor/wheels/platform that are well matched and robust. I have already fried a servo trying to start with that. I also figure that by the time I bought motors, plexiglass, wheels, etc.

Homemade digital compass

Some time ago OddBot posted this circuit for a homemade digital compass based on hall effect sensors:

Unfortunately CircuitBurn couldn't make it work. However I'm inclined to try again. A cheap DIY compass would be great.

So if anyone has ANY idea as to how this could be achieved let's hear it. It could be an improvement on OddBot's circuits or something completely different and wacky :D

Vacuum forming plastic parts.

By ezekiel181

August 14, 2009

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.

Hi all,

In case anyone wondered what happened with that dude with his wooden CNC machine, well I'm still kicking :)

I have finally reached a milestone with this guy, software seems fine, motors turn, everything is mounted back in it's place.

I have modified the Y axis to acomodate the Z axis, reprogrammed the motor controllers many times over and over, added radiators, killed and revived the arduino software .... etc, etc, ....

And finally it came to this:

PAPERduino

This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D

This is the the first version of the layout design, next we will try more designs, and another materials.

You just need to print the top and the bottom layout, and glue them to any kind of support you want. We hope that you start making your own boards. If you do, please share your photos with us, we would love to see them ;)

DIY Picaxe 28x1 USB Headphone Jack Programming Cable?

By snowpenguin

March 17, 2009

Hi, I'm somewhat new here.

I'm in the process of building my first Picaxe robot based on the 'Start Here' Bot. So far I've recieved my motors and wheels from Pololu and my Picaxe 28x1 Starter Pack from Sparkfun Electronics. Sparkfun said that a programming cable wouldn't be included, but they charged quite a wad of cash for one, so I bought the kit anyway since I couldn't find it anywhere else relatively cheaply like I could here. The only other one I found cost like $60.00!

DIY wireless, possible or not?

By CaptainTuna

February 21, 2009

Hi guys!

Sometime ago i had an idea in my mind about a DIY wireless link between, say, two MCUs. But the point is that i never tested it. I just wanted to know what you thought about it and if you think it could work (you are the electronic gurus after all :) )

It should work like this.

-Receiver has the antenna attached to the base of a darlington, and the signal received goes to the MCU (if not enough maybe i could make a bigger darlington, maybe three NPNs)
