Super Fast 3D Printer – Carbon 3D

at 3:16 pm. Filed under Cool Gadgets, Insane Equipment

 

3D printing technology has come a long way over the past few years. The speed and strength of the prints is what has made me think twice about purchasing one. The speed and strength issues has changed with the introduction of the Carbon 3D system.

 “UV light triggers photopolymerization and oxygen inhibits it. By carefully balancing the interaction of light and oxygen, CLIP continuously grows objects from a pool of resin.

CLIP moves beyond the limitations of 3D printing to offer unprecedented speed, quality, and choice.”

Laser Oscilloscope using two Speakers

Laser Oscilloscope using two Speakers

 

Kerry Wong has built a great Laser Oscilloscope using two Speakers. Of course this is not something that can be used to measure any real voltages or waveforms with any accuracy, for that you can use any used $50 scope. What this one does is produce a great visual display. You would be able to record separate right and left audio tracks to produce any light show you like.

Via: Dangerous Prototypes

“A rod (must be made of none magnetic material) was glued onto the cone of the speaker using epoxy at an angle. So when the speaker vocal coil is energized, the vertical movement of the speaker cone translates into the vertical movement of the rod. The other end of the rod was glued onto one axis (one edge of the mirror). Another set of identical actuator mechanism was used to control the other axis. A long screw was used as the support point of the mirror. The length of the screw was chosen so that the mirror sits on the screw tip and can rotate about freely. The picture on the right above shows this configuration.”

DIY Oscilloscope using Arduino Uno and Mega

DIY Oscilloscope using Arduino Uno and Mega

 

If you are interested in making a very basic scope to monitor some simple things before you spend the money on a real scope have a look at the work that vaupell posted in the Element 14 community. He tried a number of internet scope projects until he found this one that worked like a charm.

“After trying many different versions of code and tutorials, I was unable to get a single one to work, and all the tutorials and guides around was 2-3 years old. Not sure if it is the IDE or the actual hardware that has changed in such a way that it didn’t work anymore. I finally found a working oscilloscope from a Japanese website, (linked below) and a working TFT screen library, meaning i could read the various signals received. Clearly the limitations are 0-5v but that is fine, what i needed to know is either wave type and frequency, and this is sufficient. It also gives me an indication of the amplitude which is just a nice bonus.”

Raspberry Pi Minecraft Blocks with NFC

at 4:47 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Game Hacks

 

If you are into minecraft you will soon be able to use some technology to interact with the game using physical objects. Adafruit is making this possible with an NFC reader that they will be releasing soon.

 

“Coming soon to the Adafruit Learning System, a project to make paper Minecraft blocks that interact with the game on a Raspberry Pi using NFC (near field communication)! Swiping a block on the Adafruit PN532 NFC reader causes it to be created in a Minecraft world running on a Raspberry Pi.”

Custom DIY RFID Smart Lock

at 7:42 pm. Filed under Cool Gadgets, Electronic Hacks

 

RFID technology has rapidly been getting cheaper and simpler for the DIY enthusiast to get into over the years. The video above uses a Raspberry Pi and doesn’t have build instructions but that doesn’t matter much. Any microcontroller can easily connect to the heart of the access system which is the actual RFID reader. An Arduino could be used instead, it could be made stand alone instead of network connected for a simple setup. Julian Ilett picked up one of these inexpensive RFID readers, it looks very impressive for the price.

Video Game Repairs

at 5:31 pm. Filed under Cool Gadgets, Game Hacks

 

Video game play used to be an activity that was played in an arcade with a pocket full of quarters. There is still a huge following for these classic games. Thanks to the repair work that guys like arcadeuk do they will be kept running for years to come. It is interesting to see that there are lots of mods that improve things like the need for battery backups etc. I am glad that there isn’t the same nostalgia keeping 286 computers running!

Fly Swatter Compact Fluorescent Light Hack

Fly Swatter Compact Fluorescent Light Hack

 

If you have one of those electronic fly swatters kicking around you might want to hack it into a cool looking light. Steven from RimStar has just completed his Fly Swatter Compact Fluorescent Light Hack. The fly swatter is powered from 3 volts (2 AA batteries). The circuit produces a high voltage that electrifies a grid which the fly will short out through his body. The grid is removed and the circuit is modified slightly to optimize it for use with a CFL bulb.
