Edge Lit 481 Digital Voltmeter Display

at 11:36 am. Filed under Complex Hacks, Crazy Hacks

 

This Edge Lit 481 Digital Voltmeter Display totally makes me want to build a clock with this mechanism. Can you imagine talking a measurement with this meter that oscillates, it would make a ton of noise. I can see this being great help if you were siting on a stable reading and waiting for something to avalanche.

“These early NLS digital meters used a resistor dividing network and stepper relays to select the display digits. If you see one of these in operation you will hear a lot of mechanical relay noise as the range and digits are selected.”

DIY Vacuum Chamber

at 9:56 pm. Filed under DIY Hacks

 

Chris Notap shows us how to make a DIY Vacuum Chamber for under $30. The heart of the vacuum chamber is a recycled compressor pump from a donor fridge. It is simple to construct with a piece of wood as the chamber base and something as simple as a mason jar acting as your chamber body. A few pop bottles are used as a simple free valve. You can see some of the experiments that can be done with the chamber below.

Hacking Heavy Trucks

If you are looking to have some fun with the network of your big vehicle this video would be fun for you. The CAN bus is probably the vehicle bus that you have heard about but there are many other bus standards that are used when digging into your semi truck. Instead of purchasing a $100,000 truck they built a truck electronic emulation systems.

Proto G shows us a Great Alternative to Regular Helping Hands. We use them all the time to hold a few things in place when you are soldering etc. But they are often not as precise as you would like to have them. These machinist  clamps and articulating arm look to be a great addition to any work bench.

Baby Bottle Robot

at 12:05 pm. Filed under Funny Hacks

 

Do you have a baby that is keeping you up all night? This Baby Bottle Robot uses negative reinforcement to curb the baby from continuing. This robot will gently swing the bottle over to the crib, punch the baby in the face to firmly lay the baby on their back and of course drops the bottle within reach of the baby. Give this a few days of operation and you will be happily sleeping through the night with no more interruptions.

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. ”
