Replacing three remotes

Idea

You know the problem – with every new gadget comes a new remote control, and while there are programmable and universal remote controls out there, they will never just do what you want.

The three main remotes in my living room.

For controlling my tv, my digital box and one of […]

Fakes from China

Inspired by a Youtube video from Bigclive I ordered some Solar Power Rechargeable Flash lights. I knew the risk but I thought it would be a possible way to get hold of some small amorphous silicon solar cell modules for some own projects.

Today I received my package from ebay seller heavends. And […]

Hacking an AVR programmer II

This is a follow-up of my most popular post, Hacking an AVR programmer.

MX USBasp v3.02

Recently there have been quite a few comments about a new version 3.02 layout of the USBasp programmer available from many Chinese ebay sellers, which appears to be incompatible with my previous hack. The problem is still that […]

An USBasp in a new design II

Most of the time I design and debug my AVR projects on solderless breadboards nowadays. And for that I have been using some different types of programmers by now: starting with the good old STK500, to different versions of USBasp clones from Chinese sellers on eBay.

In order to connect the programmers to the […]

An USBasp in a new design

Just a small teaser: today I received my circuit boards from PCBgogo – a layout which I just had sent to the Chinese manufacturer last Sunday.

The finished circuit board from China.

It is a USBasp, which can be placed on a breadboard and at the same time supplies the power rails […]

OctoPrint – a new attempt

It was not so simple to set up a Raspberry Pi as a 3D-print server as I had hoped. It started with issues with the WiFi-dongle, continued to a complete black out on all of my USB web cams and finally I gave up…

I reflashed the SD-card with the latest full Raspbian Jessie […]

OctoPi – WiFi issues

Next step in my journey into 3D-printing would be to set up a server to remote-control my 3D-printer. Since two weeks ago I have a spare Raspberry Pi 2 lying around and Google quickly revealed the existence of OctoPrint.

Ok, downloading the image of OctoPi and writing it to a micro-SD, making the necessary […]

Improving the Wanhao Duplicator i3 – Part 1

Yesterday I got my Winhao Duplicator i3 and when I was setting it up and adjusting the print bed I thought: “Is it supposed to be like this?”

The print bed is a heated aluminum plate which is mounted on top of the Y-axis sled by four M3 screws, one in each corner. These […]
