Spotted!

Long time since a posting and spotting someone. Toooooooo busy at work, overworked! Anyways, Spotted 9W2OMA's jelopy at Tropicana City Mall, near the main entrance. Been a while since i have met him. Also spotted 9W2BBS, while driving back home that same night.


Happy new year to all !!!

Homopolar motor

The battery was placed upside down. The magnet is at the bottom. The copper wire was exposed at the contact point. Go to dealextreme.com to get good RE magnets.

Thanks to 9W2AXN and 9W2BIL.

Update on latest project.

Looks over sized.
Winding supposed to be 20" long but now 27".

:-}

Drilled 3, 1mm holes and threaded ends of the wire to get tension on the windings.

The remaining wire comes out from then inner side of the tube.

Winding up.

Went to a machine shop and used this lathe.
.










Placed the 4" x 3' lacquered pipe in the machine and ran it at a blistering speed of 25rpm. Thats the slowest setting. :-) Should have started the winding a about 3 inches lower....would have had more winds.

Magnet wire winding completed.Measured 21ohm total resistance.

MyBytes opened for business...since 2 weeks ago

The Apple retail out is now opened. Been too busy to post, been working overtime due to some complications.

Anyways, Come down to have a look at the new Macbook and Mac Mini. The NEW iMac and Magic mouse are not yet approved by SIRIM or as it is stated on Apple Malaysia's website "Pending for agency approval".


Also we have laser engraving service for engraving any non-reflective surfaces. Tried on copper and chrome surface, does not work.

But have engraved on iPod Nano, Shuffle, Nokia handphone and other engraveable materials. BTW, the max engraving area is 60cm x 60cm....

Vids of engraving process can be seen here on facebook..

For more info drop by at Tropicana City Mall, Lot G 25.

RAE 2009-2

Exam date 16 Dec 2009.

New project in the works.... :->

Thanks to Basir, 9W2BSR, managed to find the shop selling magent wire. Shop was closed on Monday and Tuesday and finally opened today. I told my buddy they would be closed for Raya, but we went junst in case on the outside chance that they might not be celebrating raya.... :-) Shown here a spool of 0.60mm 2Kg of wire. GET IT BY THE KILO, IT'S ALOT CHEAPER. My evil rich friend is financing this project. Actually only wanted about 310 meters, but not sure if 2Kg is sufficient. If your buy by meter it costs RM1/meter.That work out to be RM310. We paid about RM100 for 2Kg. Price varies depending on copper price in the market. We hope there is enough length in 2Kg to get our project going.

TTFN for now.

Silent Key...Al-Fatihah

Inna lillahi wa inna ilayhi rajeun.

Was informed that a fellow ham, Mamat 9W2XSV, mother passed away last night in Tampin.

Semoga roh nya dicucuri rahmat dan di tempatkan bersama orang-orang yang beriman.

Al-Fatihah.

C Greetings

Salah silap harap di maaf.

Got me a new tip.

Went to Pasar Road after a very long time. More than a year, But did not get the items i actually wanted to. Just 4 days back was searching the net for digital multimeters. Didnt have enuf moolah to get one. Anyways I finally got a finer point tip for my Hakko. Cost me only RM18. This one is 0.25mm as compared to 0.5 that comes with the iron. The older Hakko broucher show only these 2 replacement tips, the new has added 2 more. Got it from Maplin.




Next, a digital multimeter. Fluke about 550 $ Sanwa about 150 $.

Spotted!

Spotted 9W2JAT's jealopy in a traffic jam along Jalan Putra. The driver was a YL but check with McMc reveals that the call sign belongs to an OM.

Silent key

I was informed via sms by 9W2AXN that his father-in-law went silent key and is on his way to Gopeng.


Inna lillahi wa inna ilayhi rajeun.

Sedekah kan Fatihah untuk roh allahyaraham.

Al-Fatihah.

Protecting your PCB

A completely cleaned PCB.
This will teach you how to protect you PCB foil pattern from oxidation. I am using a unetched PCB for demonstration. You would be doing this AFTER you etched you PCB.


















I used a cotton bud, you could get an appropriate brush to do the same. The trick is using clear varnish to the tracks BEFORE soldering. Here i am applying varnish to to top part of the PCB.


















This is what it looks like after the varnish is applied. It takes about 2 to 4 hours for the varnish to completely dry. This depends on how concentrate your varnish is. You can mix thinner in your varnish to dilute it if it takes too long. Also i do not recommend a very thick coat.

















This is what the PCB looks like after a few days. Oxidation set in. Notice the part of PCB varnished is not affected.




















This is the best part. Varnish not only protects your PCB, it also acts as flux which you don't have to wash off.



















Top view of the solder joint. It perfect. So it protects your PCB and functions as flux. You can solder while the varnish is not yet dry, but it tends to be sticky. So take care. Oh...if you don't want to get high while varnishing, use appropriate protection.

Spotted!

Went to my friends house in Klang, Amazing View apartments, Spotted this jelopy in one of the parking lots.
Also left behind my name card on the windscreen.

Spotted!

Spotted Alan's car near Warisan Maju, but no sign of Alan. Maybe he was across the street having a Tango Tango with some friends.

Spotted!

His name is H. A. Rahim and uses 9W2XYL callsign, was spotted parked outside PWTC. Probably waiting for fare. :) I approached him, introduced myself to him. Friendly chap. Satu hari nanti kita roundtable.

Jigsaw

About 3 years back i bought 2, 1000pcs, Glow in Dark Jigsaw puzzle for the kids. Does not really glow in the dark.
























This is what it looks like during daytime.








This is picture taken in the dark with a bit of touch up.


























Enter my UV light.
























See Basir, my BIG UV light does have other use for it... :)

My PicKit2

This is my OEM PicKIT2 i got. USB cable not shown.










Found a small container. Shaved of holes for usb and ribbon cable.





This is my 40 pin ZIF with RJ 45 as a ICSP socket.

if (PIC with <= 20 pins)
{ switch to down position;
place PIC in pin 11 on ZIF; }
else
{ place PIC in pin 1 on ZIF;
switch to up position; }




The PicKIT2 comes with a button for reprogramming last program. Since i am find it easier to press the "WRITE" button on the screen i did not make an opening for that button.

RAE 2009-1

Thoses interested in sitting for the RAE can register now with SKMM. Exams will be on 24 June 2009. Closing date for registartion 17 April 2009 5pm. Download the registration form here.

Cleaning PCB

To remove of oxidation, grease from PCB

Any grease or oxidation will make it difficult for the solder to stick. If your PCB is unclean, the best way to clean it is to get some household veinger, pour in a container large enough to place your PCB in. Add half teaspoon of salt and stir it. Add half cup of water. Then place the PCB in this bath solution and stir/shake the container for about 1 minute or so... You should have a extremely shiny and a bit smelly copper. Rinse under running water. Dry and start soldering. This tip was given to me by 9M2CF, Uncle Chow.

MU 1 - Liverpool 4

Last nights Liverpool's victory against the arrogant MU was fanstastic. Though i miss the first half, due to work, the second half was very good. Should have been 1 - 5, if Gerrard had scored a sitter, but he balloned it! Now Liverpool didn't just beat MU, we trashed them. Fewer back passes and more counter attack, more like Liverpool in the 70'. Kudos to the team.

Spotted!

Spotted this jelopy a while back but did not have time to post, and since my pc down, had to xfer pic from phone to another pc and post this. Spotted 9W2TZE 4x4 in Certral Market parking. During Chap Goh May......
