Repair/Hack: Knog Front Light to Rear

My Knog front light used to look like this:

But unfortunately, it now looks like this:

Well the story is that I wanted to change batteries, and to do that you gotta push the plastic body that encases the batteries out from its silicon body. And either I was too rough, or I had done it so many times that the LED got severed from the mounts.

Oh well! Time to hack it. It was originally a front white LED, but I already have a better blinker so I thought I could change it to red to mount on me helmet! Alas! I found a red super bright LED in my toolbox (the perks of being en engineering student).
I thought I had recorded the whole process, but turns out I only recorded the part when I was just fiddling with it.
1. Get a soldering iron and melt the solders holding the LED in place.
2. Suck the solder using a sucker
3. Rinse and repeat till there is little solder left.
4. Use small pliers top hold the LED and melt the remaining solder on the mounts, wiggle the LED free.
5. Put the new LED in, put in new solder and cut off excess metal.

Done! This post was inspired by Saving a light by Den

Chain seizure



As I was away for something like 7 months, when I came back to my market bike parked at the void deck it was still there! Awesome, it seems my lock strategy is working fine...

But when I wanted to use it, i noticed the front tire was punctured... So Yesterday I went to fix the puncture, only to see that the chain was heavily rusted and that it has seized! Some parts of the chain wouldn't move anymore, I tried just putting some lubricant and using my hands to try to force the chain to move... Much like how I have seen others do when they break a chain and put it back together...

It didn't work. I went back home to get WD40 and two pliers. First attempt it didn't work still. Well the thing about WD40 is that it takes some time to do its magic, its been many time proven! Just spray WD40 and wait, and get back to what you were doing! Problem solved!
