555 timer controlled heated print bed

It has been some time since I posted something but i’m really busy since this is my final year of school. I have been busy for school but of course also making things! Currently i’m working on my new 3d printer, a prusa mendel and some other small projects like this one.

I do have a Ultimaker and thought I wanted to try out a heated bed because I have some trouble on bigger prints, warping etc. so I thought about it and took a standard 100x160mm pcb and designed a pattern in eagle to mill and make a heated plate/bed. I couldn’t find a heated bed designed these dimensions (since this is a standard pcb size?) Also, I could buy a heated bed, and maybe I will buy it for my mendel, but for now I just wanted to try it out.

Webkey hacking

Just a quick post..

I recently got like 15 webkey devices  and here’s how to make them direct them to your own site, make them start a program or your mail or whatever.  But first, what is a webkey? As you can see on the picture these are like some sort of buttons with a USB cable on it.

A webkey is a device which you plug into you USB port and says it is a HID (keyboard) device  which starts the “run” prompt if you push the button (under which is actually a real push-button), then it “types” a website and “pushes” enter and starts the website.

The beginning of my domotica controlled room

Today I finally got the chance to show you one of my latest projects, the automation of my bedroom, a domotica  controlled room. In this post I will guide you trough the process I went through making this possible:

Well how did I managed to do that?

Ultimaker Micro Sd-Card extension

Today I thought it would be a good idea to make A  sd-card reader as an extension for my Ultimaker, I designed it for the newer electronics which can use the SPI pins because there is a break out to an expansion header. Because I printed a prusa mendel on my Ultimaker a few weeks ago and I’m aiming to use Ultimaker electronics for it the new printer.
