And time passes by...

Hi all,

It's been more than a month since I last wrote anything here... I'm still alive and kicking... Ramadhan is here too so schedule, and the pocket, will be much constrained...

  1. I loss a dear friend few days ago. He was a senior member of the local amateur radio community who goes with the callsign 9M2DS... Lovingly called Pak Dollah by the gang... As other sites already pay tribute to him, I'll just provide the links here...
    From UNIARM
    From MARTS KLSP

  2. My last project, the LED Blinkers had some problems that need real rectifications:
    - The LEDs burnt out and some of them operate intermittently. I believe this is due to the low quality LEDs used and driven by PWM instead of the normal constant current mode.
    - The acrylic casing for the front is distorted after prolong exposure to sunlight (and the associated heat).
    - Rectification is still in the making. Better quality LEDs have been acquired. Will use constant current mode instead of PWM and will be making PCB for the LEDs. The prototype LEDs were hardwired.
    - The challenge now is to find suitable casing... milling solid aluminum for the casing is just too tedious and costly...

  3. Other than the above, I've been generally lazy for the past weeks... I'm not sure if it's the new workplace, the growing daughter or something else... nonetheless, I'll be working on something soon... just to get myself back on the active mood...
