Audio interlinks

How do you go from a 3.5mm stereo jack on your laptop to an XLR3 female socket in the church wall that links up to the PA system?

This has plagued me for a while now, and my first attempt at solving this problem involved connecting a 3.5mm male to an Amphenol XLR3 male from Dick Smith using 4-core shielded audio cable. Basically the tip and ring were connected to pin 2 of the XLR connector, and the sleeve was joined to pins 1 and 3. This didn’t really work as there was significant background hum for some reason.

Next tried a few adaptors and cables. Went from the 3.5mm stereo socket in the laptop, connected via a standard 3.5mm male-male stereo-stereo cable to an adaptor that turned a 3.5mm stereo female into a 6.3mm (6.5mm, or 1/4″) mono male, which then fed into another adaptor that converted the 6.3mm mono signal into an XLR male connection to feed into the wall. But that created hum as well.

Which got me thinking about the shielding, since the shielding in the first cable wasn’t connected at all, and the shielding in the second cable was non existent.

Did a bit of searching, and found something similar to do with an RCA going into an XLR3 male. The solution that worked in the end was to feed the tip and ring of the 3.5mm male through two cores and join them at the other side, soldering them together to pin 2 of the XLR3 male. The sleeve was fed through another core and was connected to pin 3. Finally, the all-important cable shield was soldered only on the XLR end to pin 1. This solved the hum issue, and the stereo signal coming from the 3.5mm socket in the laptop could be hooked up straight into the church PA. Nifty.

… and our Canon camera is finally fixed. After an unfortunate incident at youth group, the lens was jarred and photos were unfocused. Dropped it off at the Canon repair centre in North Ryde in the first week of March, and after many frustrating calls and delays in Japanese parts, it was finally repaired and functional. Now to make sure that it’s not dropped any time soon. Still can’t believe the IXUS models are so fragile, and that a jarred lens costs that much to fix.

Thinking of a title is such a pain.

My security card stopped working this morning suddenly. The card reader wouldn’t let me into the building so I had to trek to the other end of campus to go to the security office where they destroyed my card and encoded my student card. Problem is there’s no place on the student card to put a hole in so I can attach it to my retractable key holder. I’m so going to lose the card or get locked out. What a dumb design!

In other news (haha as if this is news…), there was a funny guard on the train home. “This train terminates at Gordon, the next train to Hornsby is on platform 3. It goes to Turramurra, and Hornsby… [pause] I think… and then Gosford? Whatever.”

The Migrant Syndrome

Filed under: Christian stuff, Observations, Personal — danny at 11:44 pm on Sunday, May 6, 2007

A few of the ‘team leaders’ from the english congregation at church met with one of our pastors this afternoon to have an informal chat. It was a productive time and a lot of things were thrown around for improvement.

One thing that has struck me while serving at a chinese church is the parents of the youth. Apart from being a non-Cantonese-speaking Taiwanese at a Cantonese church, being of the ‘third culture’ generation as one of my friends puts it (i.e. not fully part of the Chinese or Australian culture and so creating our own hybrid one) makes it more difficult to understand the mentality of some parents. Cases in point: (1) pressure your children out of ministry to do well at uni; (2) not fully understanding the idea of an english ‘youth group’; (3) putting excessive pressure on children to perform well at school at all costs.

Now, many parents of youth I know aren’t as bad as I make them out to be. Often they’re appreciative, considerate and genuinely concerned for the wellbeing of their children. Which is hard for their children to understand, but in a few years time they will. Our pastor said something today though about the migrant syndrome which really hit me hard and made me reconsider the flak that I tend to throw the parents’ way.

Many of the people at church are migrants or children of migrants. My sister and I are too. As children who have grown up in Australian society, we rarely appreciate or understand how our parents feel and what drove them to immigrate from Hong Kong, Taiwan, China, Malaysia, etc to Australia. Our pastor, however, being a migrant himself, gave a bit more insight into this matter, and you can see the painful logic and reality in his point of view.

Migrants are basically like uprooted people. They are removed from their comfort zone, their friends, their family, where they grew up, where they are accustomed to, where they can communicate readily without feeling like a second-class citizen (or worse). They move to a foreign country, learn the language, have very few friends or connections, and bring up a family, all while feeling insignificant and out of place. What for? Perhaps for a better life for their children - a noble goal which most Asian parents strive towards.

So what would they want for their children? A secure future. How do Asians know best to do this? Through education. Aggravating factors include parents pushing their ideals and dreams onto their children. They want their kids to have what they couldn’t have - connections, comfort, security.

So perhaps it’s necessary for the third culture kids to give way a bit, and for the parents to give way a bit too. Third culture kids are struggling under parental pressures to study, and peer pressures to conform. Rebellion is rife. Parents think they don’t understand their own children, and children can’t understand why parents do what they do.

It gets particularly counterproductive when these struggles affect ministry. When parents view a university degree above serving God by spending time ministering to his children. When parents view the HSC above Christian fellowship and encouragement. When parents ram Christianity down their children’s throats and make them (naturally) rebel, and sadly run from the truth.

Let’s pray for an increased understanding between both parents and their third culture kids. Pray that parents wouldn’t put undue pressure on their children and thus frustrate them. Pray that kids would understand their parents’ hopes and respect them, while having the growing wisdom to choose what to do with their own life.

Road rage

Image106.jpgApparently if you accidentally cut in front of someone who is rounding a bend at 50km/h and they honk you, and then they perform a near-crash manouver to try cut in front of you again and you honk them, it instantly makes you a blint part of the female anatomy and also a procreating homosexual. Not exactly in those terms of course.

In any case, stay away from VHY-785 and it’s red-P Lebanese driver.

PC-Club

Filed under: G33k stuff, Personal — danny at 5:15 pm on Tuesday, April 17, 2007

One of the youth from church has been asking for work experience ideas lately, and one of my suggestions was working for a computer manufacturer, much like I did back in year 10. But what computer maker would willingly take on a year 10 kid that they didn’t know? So I decided to look up the maker that I worked for back then, PC Club in Rhodes, because I knew the owner’s family.

Little did I expect, when I googled “PC Club Australia”, the first results that popped up were big headlines screaming “Microsoft wins $1.3m in piracy case”. After clicking around the articles (e.g. SMH and Microsoft), a sinking feeling came over me.

Maybe I should remove this reference from my CV…

IMG_0351_susie.jpgUp in Katoomba last weekend with the youth group from church at KYCKstart, a conference aimed at high-schoolers. It was my first KYCK, and it was absolutely gobsmacking to see a couple of thousand youth and their leaders meeting in a big tin shed in the Mountains singing, learning and praying together. Apart from the main session talks, the free time we had with the youth from 180 was just so fantastic for getting to know them better and for everyone to gel.

Unfortunately no photos from me since I only took the video camera (which I subsequently got busted for since you’re apparently not meant to film anything at the conference). But I’ll steal some photos from friends and post some up - thanks Susie!
IMG_0345_susie.jpg

Highlights include:

  • Driving up to Katoomba with Andrew, Matt, Nate and Ringo.
  • Getting lost at Katoomba station, taking the wrong turn into a dead end road where a bunch of drunk homies were hanging. Nearly ran one over as he sidled in front of our car as we tried to frantically do a three-point turn to escape.
  • Great meals and great times sitting around and just talking to youth.
  • Challenging and refreshing talks, reminding us of the cost of following Jesus, and God’s unconditional love for us.
  • Capture the flag on Saturday arvo and being stuck in jail with Simon. Our team won!
  • Lightning Charades and everyone getting involved. Matt trying to act out ‘birth’ and ‘egg’ one after the other.
  • IMG_0319_susie.jpg

  • Late-night poker and chilling with the leaders and youth in our house.
  • The drive back, getting stuck in traffic on the Great Western Highway and running out of petrol, having to drive back to refuel. Then taking massive shortcuts along small roads parallel to the railway line, basically avoiding all traffic. Andrew being woken up by a nasty gravel road.
  • MSN display names or messages from the youth after KYCK, including “Kyckstart was fabulous x100000″, “Take out the knife, make the cut” (a big idea from one of the talks, about sacrifices to follow Jesus), “KYCK was GGGreat, thanx leaders”, and “K is Y the C best K”

Second Life in Canberra

Filed under: Observations, Personal — danny at 6:36 pm on Wednesday, April 11, 2007

Popped down to Canberra for a few days to help train the Aussie biology olympiad team. Feels almost surreal, since I spend quite a bit of time down there with the olympiads. Driving is always fun - I find that I need at least 8 hours sleep to not microsleep on the road. A bottle of V and some Disney songs help.

IMG_0005.JPGLots of dodgy drivers on the interstate roads. Here’s a red P-plater tailgating another car, only 1 car-length behind, at 110km/h.

IMG_0004.JPGThe weather on the way down wasn’t fantastic, but despite this, skydivers were still in the skies around Picton. This one (on the right) was tumbling pretty fast though and appeared to be spinning out of control. Would have had quite a crash landing I imagine…

IMG_0019.JPGAnd finally what the trip to Canberra was for: the Australian Biology Olympiad Team for 2007, competing in Canada in July against 40-odd teams from countries all around the world. They’re still in Canberra at ANU working hard preparing for the competition. We had a team dinner on Tuesday night with some program staff, a bunch of people from the office, and a good friend and long-time supporter of the biology program, and then drove up Black Mountain after some late-night dessert. Standing next to Telstra Tower in hoodies looking down at a metallic device beeping on the ground probably wasn’t the best thing to do. But how else do you take a nice team photo with auto-timer?
