This camera was my sister’s, LCD shattered, probably from dropping it. Also the lens might have been stuck, but I easily got it back on track after opening it up. Quick fix, just order a new LCD from ebay for about $20, swap it out and that’s it. Tearing it apart is pretty self explanatory, [...]
Simply put, its impossible to flow loads of current through a microcontroller to control something such as a solenoid, large relay, contactor, or Motor. That’s why we have Metal Oxide Silicon Field Effect Transistors (MOSFETs). There are two types of MOSFETs, N-Channel and P-Channel, lets focus on the N-Channel MOSFET. As a hydraulic comparison, a [...]
I found a ProView LCD monitor in the trash. At the time, I figured I could use it together with my laptop to create a dual monitor setup. When I powered up the monitor it wouldn’t power up, and even if it did power up someone who threw away the LCD monitor foolishly cut off [...]
I had a PCB already made, with an ATmega328 soldered on. I had an AVRISP MKII laying around and an Arduino Duemilanove. Rather than desoldering the ATmega328 off the PCB and plugging it into the duemilanove, I just used the ICSP port I had on the board.
Power up the PCB so that the ATmega328 or [...]
A group of my friends are DJ’s known as Desi Jammers, and did DJing at my Birthday BBQ. One of their turntables had an issue with the LCD reading “no disc” The CD would never spin up and its like the laser had issues reading the disc.
First step was to remove the laser pickup assembly [...]
One of my friends had this lens cleaner for glasses, but I decided to try it on my BlackBerry and it actually made the surface of the screen worse as if it was etched with rocks or something. Looked really dirty. When the screen was on you couldn’t really notice anything, but when it was [...]
During rainy weather a friend accidentally dropped his BlackBerry into a puddle. After that, the trackball stopped functioning properly. So I took it apart.
Next pry the backplate off the phone with the plastic screwdriver.
Here’s a video to help you guys out in taking apart the BlackBerry 8900.
On the reverse side of the blackberry on the [...]
Temporary Fix
If you just want to quickly check something on your mobile and want to use the trackball, you can do this temporary fix until you get the time to fix the trackball entirely. First lock the phone or put it on standby. If you have it, drop a tiny bit of isopropyl (rubbing) alcohol [...]
I guess I left my charger in the office over the weekend, so I didn’t have a way to charge my mobile. Thats when I looked closer at the USB mini connector on it. It has the 5 pins 1 of which isn’t connected and they’re able to move around in a space of about [...]
After my magenta stopped printing on my HP LaserJet 1600, I figured the magenta toner went out, so I refilled the toner and changed out the reset chip. However, it still didn’t print properly. I had a feeling that maybe I messed up the drum on the cartridge, so I ended up buying a new [...]
