Make a Emergency Phone Charger from a Pencil

at 9:16 pm. Filed under Cool Gadgets, Electronic Hacks

 

Language Warning on this video by AvE. If some swear words turn you off this video isn’t for you. This is the type of project that could come in handy when you find yourself stuck in the bush with no stores in site. We are shown how to use the resistive properties of the pencil lead to act as a voltage divider and drop the voltage to a save level for phone charging. It would be better to connect it to a 5 volt USB charge cable if one was handy since this will most likely have some voltage protection circuitry built into it, the cable could be cut and stripped with the knife in your back pocket.  That way if you are connected into the USB side of things you could slowly increase the voltage till the phone turns on and starts charging. The only thing to look out for would be the thing you are using as your voltage divider, if it has low resistance it might heat up and burn you.

Alarm Clock that Opens Window Blinds

 Alarm Clock that Opens Window Blinds

 

If you are a heavy sleeper you might need an Alarm Clock that Opens Window Blinds. What better way to wake up than some rays of sun shine, this is assuming that you are trying to wake up in the morning when the sun is out. If you are a shift worker this might not work very well for you.

“It is created using a Spark Core micro controller, a H-Drive circuit, and a really strong geared motor. Its cheap, simple to use, and pretty easy to make! Essentially this project allows your blinds to open and let the sunlight in to wake you up in the morning instead of waking up to that annoying alarm we all have.”

GPS Guided RC Boat

 GPS guided boat

 

This GPS Guided RC Boat project is a great way to capture some interesting pre-determined navigation scenes. The boat does a great job of navigating until it hits something or gets swamped. Joseph Fortune has a page that provides build details and code so you can make your own.

 “Here is a rough layout of the parts. The 9V battery hooked to the engine was actually one of those 7V rechargeable RC battery packs. The other 9V battery was to give the Arduino its own noise-free power source (Noise from the engines kept resetting the Arduino). Here I used the Adafruit GPS breakout board, when the project actually used the GPS shield, but they didn’t have the graphic. Other than that, this should be pretty faithful to the actual design.”

Advicy Drive-Safety Wearable Prevents Drowsy Driving

 Advicy Drive-Safety Wearable Prevents Drowsy Driving

 

Photoplethysmography sensors are popular in hospitals to measure your heart beat. Watch the video below that NickTech did that shows how the hobbiest can play with this technology. You can get a sensor ready to go from places like AdaFruit and SparkFun. Advicy uses this type of sensor to detect when you are driving drowsy. Sounds like a great product but I am also thinking it is a lawsuit waiting to happen the first time there is an accident and the technology didn’t work. Of course just like air bags, technology is here to make our lives safer but some people will undoubtedly blame the tech when they were injured due to their own negligence and the technology not being able to help them in every situation.

 

 “Advicy Drive heartbeat sensor uses a high-innovative technology called photoplethysmography, which is the least invasive technology known on the market, typically used in hospitals to read your pulse from the fingertip.

The first thing to do is to register your personal attention value threshold.

The procedure will last for 20 minutes where you need to stay relaxed to let Advicy measure the right value (this process is needed only once and this alert threshold will be then used by the App during your drive time as comparison).
At the end of this basic step, the App will use and show your personal attention value threshold with a red line on the graph and with a red band in the gauge.
Your are now ready to use the product while driving, your performance is then shown by the cursor in the gauge and continuously monitored.”

Box that can be Unlocked with a Flame

at 3:24 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Alex Glover created a locked box project, some project boxes need a secret knock code to unlock, GPS positions to unlock and dice roll combinations to unlock. I think this is the first time I have seen a box that is unlocked by a flame. Nice thing is that it is not obvious that the box is opened in this way. I think it would be nice to have a certain flash pattern needed to make it hard for observers to see how to unlock it.

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.
