Vintage Camera Raspberry Pi Hack

at 9:41 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Tinkernut took a vintage camera and smoshed it together with some mini technology to re purpose it. A Raspberry Pi, camera module, WIFI module and screen is used as the wireless camera. The completed system sends each captured picture to the cloud. The code is very basic but turns this device into a robust IOT device that is fully functional.

Yamaha AV Receiver Teardown and Troubleshooting

at 9:22 pm. Filed under Electronic Hacks

 

 

The Post Apocalyptic Inventor got his hands on some cheap Yamaha audio gear. He took apart the receiver with the hopes to troubleshoot and repair the unit. Unfortunately a cap had spilled it’s guts and leaked all over the PCB corroding it very badly. It would be possible to repair but it would take a long time. If that wasn’t bad enough many of the main high power (expensive) parts were also damaged.

DIY Cheap CNC Machine using DVD Drives

at 10:39 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

If you are looking for a project build that can probably be put together with some items out of your junk box and about $10 in parts. The main drive for the system are the motor units from 2 old DVD drives. An Arduino controls the system.

“components used
1. 2x old PC DVD Writer
2. Arduino nano
3. Small servo motor
4. L293D
5. Zero PCB”

Long Range nRF24L01 Testing

at 9:46 pm. Filed under Cool Gadgets, Electronic Hacks

 
 

Long range data transmission can be useful. There are lots of options out there but the cheap nRF24L01 modules with an external antenna can work wonders. iforce2d has done lots of testing with a nice DIY rig. He has a stationary transmitter and a receiver mounted on his car, the car rig has a GPS and SD card modules to that he has the ability to record the packet throughput based on distance.

PID Motor Speed Controller Example

at 10:24 pm. Filed under DIY Hacks, Educational, Electronic Hacks

 

SomethingUnreal has built a simple system to demonstrate how a PID Motor Speed Controller works. The system is spinning a piece of cardboard on a toy DC motor. The motor is powered by an H Bridge. An optical sensor provides feedback to the system so that it can see the actual speed and adjust the H Bridge accordingly. The software running on the PC is very nice as it allows for lots of variable playing and graphical output so you can see what the system is doing.

LED Snowflakes by Mike Harrison

at 10:26 pm. Filed under DIY Hacks, Electronic Hacks

 

Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.

HP Scanjet 4C Keytar

at 5:50 pm. Filed under Computer Hacks, Electronic Hacks

 

Using some Arduinos and a few other electronic bits this HP Scanjet 4C is made into a musical device by “playing” the stepper motor. The result is one of the best stepper motor musical items I have seen.

“You may of heard of a popular flat bed scanner named the HP Scanjet. This scanner had a hidden command set within the Scanner Control Language which allows you to send musical notes directly to the stepper motor. This is a tedious method where you have to enter the notes and durations manually into a text file (similar to G-Code on a CNC Machine). I have always used and will always use this method for my Old School music videos however I wanted to try and build a MIDI controlled stepper motor.”
