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.

“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.

Arduino Controlled Industrial Stepper

at 11:36 pm. Filed under DIY Hacks, Electronic Hacks

 
AvE shows us that you don’t always need a complex expensive setup to drive industrial equipment. A simple Arduino setup is shown here to perform some simple stepper manipulation. The Arduino is connected directly to the Stepper driver which handles all of the complex microstepping etc. All the Arduino needs to do is enable it, chose a direction and pulse some steps at it. The result is a nice and simple repeatable system.

Heavy Lift MOT Magnet

at 12:03 am. Filed under Cool Gadgets, Electronic Hacks

 
There are lots of uses for MOTs (microwave Oven Transformers).  The guys from Make it Extreme have come up with a great new use. Convert them to a Heavy Lift Magnet. They take a number of transformers, chop the top off the laminated core and weld them to a heavy base plate. They are then wired to a common power source and the surface of the transformer that will touch the metal being lifted is machined flat. The only limitation that I can see is that not all of the transformer sections might be touching the metal object being lifted. The lifting capacity for some free MOTs is quite impressive!

Thanks for the tip Curt

Gesture Controlled Lamp powered by Raspberry Pi

at 12:06 pm. Filed under Complex Hacks, Electronic Hacks

 

 

This Gesture Controlled Lamp is powered by Raspberry Pi. An infrared camera is connected to the Raspberry Pi allowing the system to monitor for wand movements since the wand has an IR LED build into it. OpenCV is used to decipher the wand movements. There are a few simple gestures that are recognized to magically control the light.

Via: Make

“After a recent trip to Universal’s Wizarding World of Harry Potter, my daughters and I decided to create a project that could use the interactive wands from the theme park, at home, to control our own props and gadgets. We called it Raspberry Potter because it was powered with a Raspberry Pi. We demonstrated the project last year at the Minneapolis/St. Paul Mini Maker Faire and this article — Ollivander’s Lamp — is the latest extension of that project.”

Raspberry Pi Zero Ambient Lighting using Hyperion

at 10:29 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks

 

If you want to jazz up your tv with an Ambilight system now might be the time. We have seen other systems in the past that were impressive but not as good as this system. This new system is still a bit kludgy but seems to work very well and is nice and flexible to work with most systems. The Raspberry Pi Zero running Hyperion is the heart of the system and allows for lots of customization. The basics of this system takes in your TV HDMI signal into a splitter, one feed goes directly to your TV and the other goes into the an HDMI to AV converter. This AV signal is then fed into an AV to USB converter. The converter is plugged into a USB port of the Pi. This is not an ideal chain but since HDMI is a secure transport of video data there is no simple way for the Pi to read in the HDMI data. Now that the Hyperion software running on the Pi can see the live video signal that the TV is displaying it can calculate and output the appropriate codes that are fired down the serial LED string. Using the serial LED tape allows for a very simple LED layout.

Super Secure 4 Factor Lock Box Project

at 10:08 pm. Filed under Cool Gadgets, Electronic Hacks

 

 

 

Adarsh Jayakumar, Timon Amirani and Cameron Boroumand developed a Super Secure 4 Factor Lock Box Project for their Cornell University ECE 4760 final project. It uses a typed code, 3 pots set to a specific value, a knock sensor and a finger printer sensor. All they need now is a iris scan! Of course this box is built out of something that can be smashed into with ease and the electronics take up almost all the space in the box but just imagine this built into your steel and concrete reinforced safe room in your home.
