I’ve mostly completed the y-axis now. Just got to do the x-axis and attach a tool and then a few touch ups.
I used the motor control and optical encoder stuff from my plotter to control it for the video.

I’m in the process of making a CNC machine out of aluminium. The finished machine should be able to work with a 400×400×60mm volume, I’m making it small because aluminium is very flexible and I not sure if I’ll be making anything much bigger than that. I’ve almost finished the z-axis mechanism. It uses a [...]

This is my latest project. Converting a broken Brother MFC-425CN into a small plotter. I used the paper feed mechanism and the printer head with the optical encoders and stripped everything else out of the printer. There are a lot of gears and stuff that are used for cleaning the print heads and pumping away [...]

This is a hardware rng I made over the weekend. It uses my PSU based power supply for the 12v and -5v and USB for 5v.
It’s based on http://robseward.com/misc/RNG2/. The voltage is read using the ADC on a 18F2550 and the bits of the voltage are XORed together to create a single random bit. Von [...]

I’ve been trying to compile some usb examples for my little 18F2550 micro-controller for the last few days and now I’ve finally got it working. Here’s a few things to watch out for.
Don’t try and port mcc18 code to hitech’s pic18 compiler. I tried without any success even trying to use examples other people had [...]

Ok, first post of the year. That’s pretty bad, nevermind. Just posting my latest endevours.
Here’s a pic demonstrating it working. A 300w power supply being used to light an LED
It really isn’t that difficult. I followed the guide to make it here:

I made my first microcontroller based robot over the weekend. It is far from finished. But it can drive around randomly. Getting something to move randomly was harder than it should have been. I realised overnight that I don’t actually need a random number generator if I want it to appear to move randomly. I [...]

Today was the competition day for the robots we built in our first year engineering class. I’m not sure the event deserves to be called robolympics but nevermind. It was fun. We didn’t win
Our robot was too slow and the gearbox fell apart during one of the six events. It was also the [...]

I lost the cycle computer for my bike a few months ago and haven’t the money to replace it. I used it as a pocket watch and that’s why I lost it. I’ve had a few ideas for projects lately and I think I can incorporate them into a neat bloggable project. A new cycle [...]
