DIY V8 Engine replicas made from paper!

You may not believe this but these ‘V8 Engines’ have been fabricated from Paper Mache. They are small and miniature to look at but are a complete replica of their originals. They even have movable engine part attachments so as to give the exact feel of the real V8 engine. Seems to be a different and quite fascinating as the parts include- a composite crankshaft, a rapid cooling rotor fan, 8 rods, 8 pistons and a multifarious multiple gearbox. This V8 engine is driven by 2�1.5V D Batteries and has a curb weight of mere 2.98kg. This mini four-stroke V8 engine flaunts a 1.000-inch bore, 0.900-inch stroke, 9:1 compression ratio, 12,000rpm max., rotary sliding vanes known as the supercharger, dual WALBRO carbs, dual electronic ignition spark plugs, and a dual juncture dry sump oil system, so as to maintain the proper lubrication. The designers and developers say that it took them almost a year to fully assemble this miniature marvel. One thing that amazes me the most is that these miniature beasts are fully functional, wow!

Home made wooden Laptop

How many of you are in need of a laptop that has an extremely low resolution and a slow processor…? I guess only a few are interested and that too for a summer project. Check out this system made from almost a scratch. It consists of a handful of chips are some hardware that you can easily get if you search your store room. The machine runs on a self hosted development environment and also allows the users to compile and run programs in ‘Chris++’. The system’s wooden looks are the best thing that I found in it.

HOW-TO: Create 360-degree photography

Would you like to shell out lots of bucks to learn professional 360-degree photography or would like to make on own your own for free? Carl at warehouse.carlh.com explains a neat procedure of getting 360 rotation animations. He says: I’ve always been a fan of the 360 degree photographs of products. Purchasing the equipment would be ridiculously expensive but creating (MAKEing) comparable equipment at home was basically free and yielded great results! Via: Makezine

Bigger the better: make your own monster quartz halogen bike light

Necessity is the mother of invention. Adverse situations often provide inspiration to people and a key to improving upon the day-to-day utilities is to subject them to not so usual circumstances. Enough with the crap, here is a guide to improving upon the one thing that bothers you most about your bike. I’m referring to that puny, good for nothing 3-watt generator lamp that most of the companies mount at the head of your bikes. More often than not, I’m sure, you must have thought ‘this sucks.’ Well, Dan too thought so. That is why he embarked on a mission to change all this. Here a brief guide to making your own Halogen light that shines with all its might: Components for building up a Halogen Bike light � PVC cleanout adaptor – a 1 1/2′ PVC cleanout adaptor is required to mount the Lamp. � PVC fitting headlamp enclosures – to complete the enclosure for the lamp. � Mounting brackets – to mount the headlight in a desired position. � 12v spot lamp – a common MR-16 sealed beam bulb is the heart of all your operations. Preferably use a 35 watt one for high beam and 20 watt for low beam. � L.E.D.s, quartz halogen lamp, switch – six high intensity L.E.D.s are enough to make a good tail light and a simple switch will give you the desired control. � Screws for holding the entire thing together and optional metallic silver finish in the form of a coat of silver paint. � Battery – of course, the most important thing is to get a good quality battery to power your light. Simple lead-based batteries will do well for the sheer reason that they do not require too much maintenance. For charging you can use an automatic 15A/trickle charger that can be strapped right on to the side of the battery. Assembling everything together Once you have gathered all the components together, you must put together everything for a glossy light. Here is how: � Fit in the halogen light in the PVC cleanout adapters and screw the PVC fitting headlamp enclosure right on top. � Drill in screws to retain the lamps. � Paint the sides of the PVC enclosure with silver color for a glossy finish. � Drill two holes in the PVC caps, one for mounting and the other for switch. � Wire in the light through these holes. � Use the European style terminal blocks and trim them to get them to fit side by side on the pins of the halogen bulbs. � Get the battery ready with an initial charge. The charger switch stays with the battery, neatly secured on the side of it with electrical tape. � Prepare a neat battery carrier and place the charged battery in there. � Drill in some holes on the reflector and put in the L.E.D.s wiring them in a parallel circuit. � Use Ratcheting plumbing clamps (preferably three one for the headlight and two for the taillights. � Mount the taillight at the rear farthest you can. This will prevent you from hitting them while paddling. � Use an L bracket to mount the headlight at the required position. � Place the switch at such a place that does not interfere with the breaks and shift cables. There you have it, a step-by-step guide to creating a powerful lamp for your bike that will put even motorists at shame. With little luck you might be able to create one in about $100. So happy biking! Particularly at night! Via

Make your own colorful and cheap Lego Zapper

Do you love collecting Lego firearms for long time before? Then you can also make your own Wii Zapper by yourself like Mrklaw, a member of the NeoGAF forums has created his own Wii Zapper with the use of blocks of Lego. Lego Technic pieces were used to create a trigger. He copied the basic idea of the branco gun and have sliding bit of technic lego, which pulls against the B button. If you select the zapper mode in umbrella chronicles, then actions like slash, weapon and others are all on the nunchunk. So, now, I have pistol in my right hand and the nunchunk in my left hand. That makes perfect IMO. But as for UC it is better to use the wiimote on its own IMO.

HOW-TO: Make a phone alarm dialer

To monitor and to protect your house from intruders a new modern device has been developed called Alarm Phone dialer. You can fix/hook this technologically advanced device anywhere in your house. It’ll enable you to monitor your house at times when you are at work. The device can be easily hooked at your house for example main door, back doors, windows, garage doors, to get high water alarm, low temperature alarm etc. This new security system can be activated to call programmed numbers and after pressing ‘Pokreni dojavu alarma’ button the system gets ready to dial and assures that phone call is successfully programmed. Its programming mode can learn several numbers and after detecting an input on its sensor pin this module can call users to report an unpleasant incident and the users can press pound key ‘#’ of their mobile to stop the device from calling another number or again. Check out how to programme numbers on this device, as depicted by Alan Parekh: 1. Press the program button 2. Pick up the phone that is connected to the same phone-line as this device 3. Punch-in first number and then ‘*’ key 4. Punch-in next number followed by ‘*’ key 5. Punch-in the rest of numbers and finally ‘*#’ for example: 061123123*061456456*# The device uses MT8880 DTMF dialer chip and a PIC 16F84A microcontroller and can learn 64 characters or digits including * and # keys.

HOW-TO: Make a liquid battery

When you need a cellphone and its battery is over then you run to fetch the charger and connect it to a power line. Have you ever wondered what would you do if there is a complete power failure…? Here is a simple solution, a liquid battery that can be built with an investment of $20 and a time of three hours. Though I am not very sure that this can run your cell phone, but it will surely give you an idea of how things work. All you will need is copper sulfate, distilled water, copper electrodes, and crow’s-foot-zinc electrode. All you need to do it is to: � Pour copper sulfate (the blue granules) over a copper electrode in a glass. � Fill it with distilled water. � Add a crow’s-foot-zinc electrode, and short-circuit the battery for 24 hours to kick-start the battery reaction. � Connect to the device of your choice. Yields one volt. Via: popsci
