Mechanical Pencil Hacked into a 0.5mm Precision Solder Dispenser

 

Thin solder is nice for doing delicate work since you can control the amount of solder applied with ease. The issue with solder is the thinner it is the easier it is to bend and deform while you are using it.  removed the lead from a mechanical pencil and Hacked into a 0.5mm Precision Solder Dispenser. This is a cool idea and cheap since mechanical pencils can be had for under a dollar.

FPV Quadcopter Shooting Roman Candles

at 5:29 pm. Filed under Crazy Hacks, What Were They Thinking

 

Fellow Canadian PIEROGRAM had some experimental fun when he was at the cottage this summer. If you have a quadcopter and want to live on the edge, strapping some roman candles to the quad might be a bit of dangerous fun. Of course don’t blame me if you burn down your house, start a forest fire or blind someone!

Heat Reclamation Chimney

at 11:36 pm. Filed under DIY Hacks

 

Ben shows us how he built a mock up of a Heat Reclamation Chimney. The idea is to capture some of the heat that exits through the chimney. When you have a look at a hot water tank or furnace that is basically what those devices are doing. Normally there is a heat source at the bottom and exits from the top, the rising heat passes through pipes that are filled with water to extract the heat. Ben has a much simpler system, he is using an increased exterior surface area brick. There is then an air space created around the chimney where a variable amount of air can be pulled out of into the room. There are some other people experimenting with this concept like Stasys Blazonis with his Chimney Heat Exchanger Project. Another area that is gaining in popularity is waste water heat recovery.

Arduino Powered Thermostat

 

Your thermostat is probably one of the most boring pieces of technology in your house. This Arduino Powered Thermostat lets you take control over your furnace and make it work the way you want it. 

“The three zone system  is also equipped with DS18B20 temperature sensors, DS1307 RT Clock, 16×2 character display, LCD keypad Arduino shield, along with various miscellaneous wire leads, connectors and resistors. 

On the software side, hbomb9000 used an add on for SublimeText known as Stino, as well as two libraries: OneWire and DallasTemperature.”

KeySweeper - Microsoft Wireless Keyboard Sniffer_2

 

Wireless devices are convenient but must be used with caution. Samy Kamkar shows us how a simple wireless keyboard can be giving away your secrets. He built this KeySweeper, it is a Microsoft Wireless Keyboard Sniffer that is built into a innocent looking USB wall charger.

Via: The Hacker News

“KeySweeper is a stealthy Arduino-based device, camouflaged as a functioning USB wall charger, that wirelessly and passively sniffs, decrypts, logs and reports back all keystrokes from any Microsoft wireless keyboards (which use a proprietary 2.4GHz RF protocol) in the area.

Keystrokes are sent back to the KeySweeper operator over the Internet via an optional GSM chip, or can be stored on a flash chip and delivered wirelessly when a secondary KeySweeper device comes within wireless range of the target KeySweeper. A web based tool allows live keystroke monitoring.”

 Kraftwerk Fuel Cell

 

With portable electronics sucking all of your battery packs dry wouldn’t it be nice to have something that doesn’t take many hours to charge up? That is where the Kraftwerk Fuel Cell comes in. Fill it up with some off the shelf camping or lighter fuel in about 3 seconds. This isn’t a quick and dirty project, it has been in development for 7 years and it has 27 patent applications.  The Kraftwerk had a lofty goal of $500,000 and has already surpassed that by over $200,000 with 42 days left in the campaign. Surprisingly this device will be ok to take into the cabin of an plane! It will be nice to see this type of device become popular as a battery power portable power source.

“kraftwerk is a fuel cell power generator. Based on our unique and award winning microtubular metallic fuel cell technology, kraftwerk directly transforms gas into electricity. The user fills gas into an integrated tank. Whenever power is needed the gas goes into the fuel cell and is converted directly into electricity. A standard 5V USB plug allows you to connect all your electronic devices supported by the USB standard (smartphones, cameras, flashlights, …).”
