This is the PCB for my second custom CMoy build. It uses a pair of WIMA MKP 10 as input capacitors and is ready to be installed on my recently finished Hammond 70009 enclosure.
This is the part list used in this build:
- Power section:
- 1 x Panasonic FC 470uF. 25V. electrolythic capacitor.
- 1 x Texas Instruments TLE2426CP rail splitter.
- 1 x DIP8 socket.
- 1 x Generic 1uF. 63V. polyester capacitor (TLE noise reduction).
- 3 x Molex KK 2 pin vertical male connectors (power input connector, power switch connector and LED connector).
- 2 x WIMA MKP 10 - 0.47uF. 400V. - Polypropylene (PP) film dielectric (input capacitors).
- 1 x Texas Instruments / Burr-Brown OPA2134PA Op-Amp.
- 2 x Generic 0.1uF. 100V. polyester capacitor (Op-Amp decoupling capacitors).
- 1 x DIP8 socket.
- 2 x Molex KK 3 pin vertical male connectors (audio input / output connectors).
- 1 x Molex KK 2 pin vertical male connectors (ground connector).
- 2 x Generic 100K. 1/4W. resistor.
- 2 x Generic 10K. 1/4W. resistor.
- 2 x Generic 2.2K. 1/4W. resistor.
Hewlett-Packard Pavilion tx2500 overheating fix.

Some weeks ago, a Hewlett-Packard Pavilion tx2500 series convertible notebook assigned for retirement came to my hands with a flickering video problem. After digging the Internet for a while, I found this PC suffers a commonly known CPU/GPU overheating problem because poorly applied thermal solutions.
This notebook can be easily fixed using a cheap copper shim and good thermal paste. There is a rather large (1mm.~) gap between GPU and heatsink filled from factory with an adhesive thermal pad. This pad diminish over time and GPU overheats very quickly. Replacing it with a copper shim solves the problem.
After spending some precious time putting all back together, the Pavilion tx2500 is on the road again running Windows 8 Release Preview without any hiccups.

I've just uploaded a new version of Moosaik, my Mootools-based Instagram browser. I would like to thank all the people who provided me their valuable feedback. There are some bugfixes and enhancements included with this version, some of which are described below:
- Updated Instagram requests to reflect recent API changes.
- Updated access token handling. Not working properly on Explorer and Safari.
- Updated image date handling. Fixed an ugly Javascript date parsing error.
- Added user profile image thumbnail to Popular mosaic tiles. Now it's possible to access user images directly by clicking on it.
- Added current user profile image thumbnail to search bar.
I've also created a static page for the project to publish all the relevant information about it.
Now, my development efforts will focus on adding shortcuts to followed users and simple mosaic paging. If you have any free time to spare and an Instagram account, maybe you'll want to try this new version and send me your comments.

In an attempt to reduce my eco-footprint, I've just moved all my server software running on my Core 2 Quad system to my Raspberry Pi. Now, with a consumption of only 3 watts at peak, the tiny board is running a Tomcat 6 server with my custom Spring Framework based blogging software (SimpleBlogger), a MySQL database server as storage backend and a Nginx as reverse proxy and static content provider.
And best of all, it's completely silent!
