Guy Makes his own iPhone

at 10:47 pm. Filed under Cool Gadgets, Crazy Hacks, Electronic Hacks

 

 

Instead of purchasing a new or reconditioned iPhone Scotty from Strange Parts decided to build his own. If he was in any other country this would have been near impossible but he was in China. There are lots of repair and recycling facilities that were able to sell him the bits and pieces that he needed. At 6:15 you can see Scotty purchase the display and digitizer from a repair facility. The parts used are probably not genuine Apple parts but rather the common aftermarket parts that are used to repair the phones if they get damaged and are repaired by a 3rd party vendor. The small shop has some impressive machines including a vacuum chamber that I am thinking a local repair shop would not have. The iPhone logic board is the main control board of the phone and since this is a phone the components are extremely small. He was thinking of purchasing a bare logic PCB and then purchase all of components separately. This would be a crazy undertaking. I think he went the better route which was to purchase a repaired one. With a huge bag of screws in hand and a ton of tiny parts he actually completed the build and now has a working iPhone!

Automated Outdoor Lighting

at 10:49 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

 

Steve Marriott wanted to have some automated outdoor lights. They will be controlled by an Arduino that will monitor some PIR sensors to see what is going on and turn lights on based on activity. A few tictac boxes were used to mount the outdoor electronics in. The project changed over time based on community help. The end result is a a completely automated lighting system that looks great and provides a ton of light.

Macbook Backlight Repair

at 11:41 pm. Filed under DIY Hacks, Electronic Hacks

 

Louis Rossmann shows how he walks through a Macbook Backlight Repair. As usual the scale of the repair is tiny and work under the microscope is needed. Some tiny jumpers and a steady soldering hand come to the rescue.

Power Supply Decoupling and Filtering

at 11:50 pm. Filed under Educational, Electronic Hacks

 

w2aew demonstrates the use of decoupling and filter cap usage. We have all seen large electrolytic caps and tons of small capacitors near chips on most circuit boards. Why are they used and without them what does the circuit look like. The live demonstration on the scope with the test PCB does a great job in demonstrating the difference with capacitor placement and operating without capacitors.

Pizza Box Robot That Shines a Laser in Your Eye

at 10:48 pm. Filed under Computer Hacks, DIY Hacks, Electronic Hacks

 
 

Michael Reeves is a software developer at Infibit that has made a face tracking robot that is housed in a pizza box, it tries its best to find your eyes and shine a laser in them. The software that runs on a PC was written in C# and uses Emgu CV which is the .NET version of Open CV for the facial recognition portion. A web cam is connected to the computer scans for a face to attack, when detected the coordinates are sent over a serial cable to a microcontroller.  The ATmega 328 microcontroller has a few servo motors connected to laser pointer. Since the servo motors can move the laser pointer in XY positions the coordinates are used to point where it needs to. The result will annoy you and your guests. I think this would be useful at popular store displays when you need people to move along after having a quick glance. If you are looking to build your own version you can find the code here.

Open Source Firmware for DPS5005 Power Supply

at 10:50 pm. Filed under Electronic Hacks

 

This DPS5005  Power Supply is a powerful compact unit. It has a ton of functionality as it is. Johan Kanflo wanted some more features though. He created an Open Source Firmware version for DPS5005 Power Supply to add those features.  Unfortunately the firmware was locked so it couldn’t be sucked out and examined / modified. The PCB has a serial port that is wired to the controller but is not active so it looks like they had a goal to allow this unit to be remotely controlled but never got to it or it might possibly be in a different version of the power supply. Johan reverse engineered how the controller operates the power supply hardware and developed new software to get the features working again but with a more intuitive feel. The serial port is also enabled allowing the power supply to be remotely interfaced with.

Via: Hackaday

“The reverse engineering of the DPS5005 can be summarised as “bring up of the STM32 based DPS5005 hardware and writing an application for it”. This is pretty much my day job but I always have the hardware schematics and the hardware design engineer at hand. This time, obviously, I had neither which was a bit more challenging. So where do one start? Looking at the PCB, I quickly found the serial port. That was a dud, completely silent. Fake port! I later realised the DPS5005 stock firmware does not even initialise the serial port. ”

UNI-T UT61E Backlight Touch Mod

at 2:57 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

 
CubeAMSPro100 has completed a UNI-T UT61E Backlight Touch Mod which adds some interesting features to the UNI-T meter. With a wave of a hand over the top of the meter he can now command the backlight to turn on or off. This isn’t a simple hack and it involved installing a custom PCB to handle the magic.
