Robo-Target

at 5:05 pm. Filed under Cool Gadgets

 

Target shooting is fun but there are just so many times you can walk back and forth setting up targets to shoot. With a bit of technology Making Stuff built a system called Robo-Target that automates the process and is controlled remotely. I think the only thing it needs now is a hit detection method, not sure what the best method of doing this is though. A piezo detection device on each target? Movement detection? All of these would have issues with false detection since there would be quite a bit of activity from wind, direct hit on the structure etc.

GSM Power Monitor and Control

GSM Power Monitor and Control

 

If you would like to keep better track of your energy usage this GSM Power Monitor and Control by Idris Zainal Abidin might be just what you need. There isn’t much details so you would not be able to build it from the article but it should be enough for some inspiration to build your own creation.  The modular build looks great even though it would not be best suited for a compact instillation.

Cliff Test – Constant Current Variable Load

at 10:18 pm. Filed under DIY Hacks, Electronic Hacks

Cliff Test - Constant Current Variable Load 

 

Check out the Cliff Test, it is a Constant Current Variable Load by TimNJ. It is based on the popular inexpensive load tester circuit that Dave Jones built a while ago. 

“Here’s some information about it:

-External AC/DC power suppply
-Fan cooled (no temperature control at the moment)
-Load switch (with LED indicator)
-10-turn pot
-Internal trimmer to set max current (currently set at 1A, but can most likely do 2-3A)
-Yellow and black banana jacks for current measurement (1A/1V)
-10x 10ohm Vishay CPF3 (3W) resistors”

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.”
