Solder Fumes are often annoying. I found this really good solution to get rid of the irritating solder fumes which always tend to rise up into my nose. If you can relate to this, you can also go through this easy solution by Jean-Claude Wippler from Jeelabs. He has described a simple procedure which does not need any high tech equipment for implementation. “A small 12V brushless PC fan, which happens to still start up and rotate reliably at 3.6V, as provided by three Eneloop AA batteries. Stuck to a battery pack (with on/off switch) using hot glue, which also doubles as weighted base for it all. The fan is slanted slightly downwards, to better cover the area on the table”.

Interested in Industrial stuff? Just check out this captivating LEGO Machine! I am sure most of you would be familiar with what LEGO is. I never expected that someone could come up with this innovative idea of making an industrial machine with LEGO blocks. Look what Oscar Gonzalez says about this cool machine. “Thanks to @ astromaf I find this absolutely amazing video of a machine or rather a set of LEGO submáquinas made perfectly simulate a complex industrial system of transportation, sorting and replenishment using small colored balls. It is so impressive that every minute that passes is more impressive than the last. By analyzing in detail the video, we see all kinds of classification systems such as color, quantity divisions, charging systems and supply and transport to a different place to bring back to the starting point where it becomes to start the whole process. Unfortunately I have no idea who has done such a machine or how many thousands of hours invested in it, but it certainly is amazing”.

I had never imagined that a SMS can be viewed in such a cool way as shown in this video. This is being done by interfacing the phone to the display using an Arduino. The idea was an adaptation from a girl wanting to create a funky looking costume with a scrolling LED display of live texts sent from people at the party. So if you want to create something new out of this idea then you can see how it’s done here. “This sms-to-LED tutorial shows how to automate the manual button input on this $13 scrolling LED belt buckle with an arduino, and then how to pass SMS messages through it. A USB Host shield connects an android phone that passes SMS messages on”.

Check out this PIC16F886 based Camera Sound Trigger that Viktor just made. The knobs are used to navigate through the systems options and set the settings you need to capture your perfect action shot. All you need to do after it is built is find a light bulb to smash or a bullet to shoot through an apple. Thanks for sending this in Viktor. “The hardware is made up of two distinct parts: analog input circuit and digital processing. The sound signals are picked up by a small microphone recycled from an old tape recorder I got rid of recently. After a lot of research on the internet and some trial and error I settled with the LM386 as the input amplifier. I used the typical application circuit for maximum (200) gain from the datasheet to make sure it has enough sensitivity to pick up the smallest noise if needed.”

Thanks to Michael Chen for sending in his DIY Tesla Coil Build. His DIY Tesla Coil Instructable takes you through all of the steps he took to build it. He is still working out some bugs in his electronics since he is able to fry some components if he isn’t careful but it does seem to work great when it is working. Only take on a Tesla Coil project is you know how to safely work with high voltage since it can seriously hurt you if you are not careful. You can also vote for this project on Instructables if you think it is good enough to be a winner, see the vote button on the top right of the page. “A Solid State Tesla coil is made by four main parts: the primary coil, the secondary coil, the topload, and the control circuitry. The Secondary : The secondary is the long, orange cylinder. It is actually a white PVC pipe covered by a lot of enameled wire. One side is connected to ground, high voltage comes through the other side. The Primary : The primary is powered by the control circuitry and it generates the magnetic field that the secondary uses to create the high voltage. It is the few turns of thick wire at the base of the secondary coil. The Topload : The topload is the metallic object at the top of the secondary coil. It provides a capacitance to the Tesla coil. The Control Circuitry : The circuits that make the tesla coil work at the correct frequency and duty cycle; based on Steve Ward’s design. “

Thanks to Andrew for sending in his DIY Remote Control Ping Pong Ball Machine Gun. The mechanism he used reminds me of the type that is normally used to launch baseballs and tennis balls. Even Nerf Gun Darts are fired using a similar method, I guess if the method works there is no need to make a better mouse trap. This system is controlled using an Arduino microcontroller and is fired by sending remote commands to it. “The electronics for this project are simple. They consist of an Arduino, a stepper motor, a ULN2003 driver chip and a couple of LEDs. I based the circuit off of my previous project “Easy CNC Controller“. I chose to use this method as it was very easy, and requires no additional parts. I got the motor from an old scanner.”
