Messing with the Picaxe editor help menu

When researching the exact connections on my 28x1 projectboard, I scowered my directory C:\Program Files\Programming Editor\datasheets\ and found user.txt.

And guess what? It lets you change the help menu in your editor.

That fourth option was not there before! All that was needed was one extra line in the textfile:
PCB hackers need to Read this F*****g Manual now!=c:\Program Files\Programming Editor\datasheets\axe001_pcb.pdf

The odd world of powering walking robots.

The servos I ordered for my biped project never arrived, so I got my money back and ordered new ones, which probably will not arrive before december. *sigh* Not to get bored I did some reading about powering a walking robot. Quite a surprising subject.

Simplified occupancy grid mapping

I have a setup, where a distance sensor, such as sonar or IR, rotates about 180 degrees and takes a distance measurement every few degrees. What I would like to do is to create a occupancy grid out of these measurements on an Arduino or, more specifically, I would like to compare two different algorithms, which create the grids.
One of these algorithms would be made by myself, but in order to make a solid comparison, I would like the other algorithm to be the one which is mentioned in occupancy grid materials and research papers, which utilizes a binary Bayes filter.

Bluetooth startup failure.

I'm building a robot using a Rasperry Pi coupled with a Picaxe board for motor controls. I realize maybe Arduino might have been the best option to start now, though I need an actual operating system on it.

Disassembling RC Car for Chassis

Hello, I am putting together a quick robot, and I figured I could skip a couple of steps by purchasing a remote controlled car, taking the frame off, and using the chassis as a preassembled remote controllde base.

 

Has anyone does this before and has any tips? What cars are good for this, and do any specifically have better chassises? Thanks!

Wearhouse Arc- Wireless headphones reinvented

I will tell you a little story about Nelson, our hackerspace member here in Shanghai. Xinchejian, the Shanghai hackerspace is quite a breeding station for new engineers. Nelson did prototype a new kind of headphones which enables you to share your music with many others via Bluetooth and an App. Control play/pause, volume, next song etc. via a touch sensitive surface on the right earcup. But I will shut up now.

How to affect a variable timer in lbink ?

Hi,

I tried to make the first example blink, everything seems very easy till I tried to give a value in the green field ? How to find this green field ?

I didn't find it in tutorials

Regards

 

For unni

Think you will want something like this for code on 28x1 from our brief shoutbox conversation, you will have to pick the value from your sensor, I used 5 as example. This is using adc pin 1, and pin B.1 to go high and turn  on your relay. Have no idea if this works or what you have for sensor, also you might need to turn relay on with a transitor depending on current draw. Please remember picaxe does not like over 5 volts.

What do you look for in 3D filament?

Name one thing that you value the most in 3D filament. And why?
