Accelerometer MMA7455

I want to use accelerometer in one of my projects. I choose MMA7455, accelerometer has leads under the case so you need some gym to fix it. I solder it with hot air and under the microscope.

Ethernet Controller, Part 2

Order PCB arrived. Time for assembly, unfortunately it did not go according to plan:

Ethernet driver

One day I got to do driver inputs / outputs managed by the ethernet.
Design assumptions are as follows:

• 20 inputs
• 20 relay outputs
• controling by www page and comand line
• UART and ISP/I2C interfaces
• all based on PIC18F97J60 with hardware Ethernet control 

Milling machine, part 2

Mechanical part of milling is done! Now should be much easier. The post describe some details about construction and first tests.

Dowload films from youtube (...and other similar)

Few years ago the download was a lot easier, you could copy the movie directly from the browser cache. So far as can be. It's just that search files on the disk is increasingly hindered. Why not just skip the browser  and download directly from server, communicate like browser? (Almost like MIDM) provide a method to download videos from youtube and the like, way fast enough and at first glance complicated, but always effective.

Milling machine , part 1

After few weeks of planning and watching lots of constructions i wanted to build something on my own. Model in 3D looks as you can see below:

Motorbike chain oiler

I am quite lazy, therefore I decided to make a motorbike chain oiler for my yamaha. Having this I would never need to think about oiling the chain! I started with browsing the Internet and finally decided to build one that doses oil due to gravity force.
