Hi guys,

I’ve decided to move my blog. It is still Rudi’s Electronics Blog.

I will occasionally maintain this WordPress blog, like replying messages and comments.
But for the new posts, I will post them on the new address.


How to Add Image to Cadsoft Eagle Schematic

Few days ago, I wanted to put a logo to EAGLE schematic.

There are couple of ways to add image to EAGLE PCB.  You could use Bitmap to Eagle converter tool or you could use the import_bmp.ulp.
But, there is limited online tutorial or tips on how to import image to schematic.
I experimented the import_bmp.ulp a little bit, and I’d like to share my technique.

In this video, I show how to import a Creative Commons license logo as a device in a Eagle library which can then be added into schematics as a part. Now, you can add any image to schematics. Personal artwork, company logo, license, or even your photo.


Soldering is Easy – Menyolder Itu Gampang (Indonesian Translation)

I cannot remember exactly when  I started to learn soldering.
But since, I now know how to solder SMDs.  I can handle 0402 very easily.

If you are a complete beginner and never done soldering before, this is a great comic and illustrated teaching instruction on how to solder that you should check out.
Soldering is Easy by Mitch Altman, Andie Nordgren and Jeff Keyzer.

Until today, this comic has been translated into Russian, Chinese and Portuguese.
I was born in Indonesia. So, I decided to translate this great comic into Bahasa Indonesian making it more accessible to wider community!

Ya adik-adik semua, selamat mencoba menyolder ria!

Few people had problems when trying to combine the zedgraph and ez430chronosnet libraries into the Chronoswatch Downloader project.

I just committed the Visual Studio Solution files into the Sourceforge directory and added the svn:external properties to automatically download the zedgraph and ez430chronosnet from different repository addresses.

So, thanks to svn:external property, now if you do SVN export from
it will also automatically export the zedgraph and ez430chronosnet.

Hope that you should be able to open the solutions file in Visual Studio and do Build without any problem.


Data logging using ez430-Chronos watch (Part 2: Downloader)

I am glad that there are few people actually use the firmware to log the accelerometer data from the ez430-watch.
Some of them asked when I can release the Windows application to download the data to PC and setup the watch.

So guys, you can now download the code as I just released them.

Remember, you need to include the ez430chronosnet and zedgraph libraries to your project/solutions.
