These look really amazing. Free Spirit Spheres has commenced limited production of the 3.2 metre fibreglass sphere tree houses and now has sphere shells and kits available for the DIY market.

Orders are now also being taken for the wooden shells and component kits and fully-finished made-to-order wooden Free Spirit Spheres. Shells can also be rented for the night.

Free Spirit Spheres has commenced limited production of the 3.2 metre fibreglass sphere tree houses and now has sphere shells (US$6,300+) and kits (US$35,000+) available for the DIY market. Orders are now also being taken for the wooden shells and component kits (US$35,000+), and fully-finished made-to-order wooden Free Spirit Spheres. (US$120,000+). For those interested in experiencing a stay in a spherical tree house, Free Spirit Spheres are now also available for rent on a nightly basis, provided you’re prepared to travel to Vancouver Island, British Columbia, Canada.

Gloom-II - Mini-sumo robot

Gloom II replaces the original "Gloom", which died of unknown causes. This is a Solarbotics Sumovore kit, which is a decent kit as these things go, but had a few issues, the biggest being a flawed trace on the main board that resulted in a short and was difficult to track down. This version is fitted with the optional BS2-compatible "brainboard" - the MCU is a BasicX BX-24p, much faster than a BS2.

The motors are 150:1 sanyo-type gearmotors from Solarbotics.The wheels and tires are from the same source. The motor leads will be fed through a hole in the center of each motor slot (that hasn't been drilled yet).
A Lynxmotion Single Line sensor at each corner provides edge detection.

QRPme - Tuna can kits

The Tuna Tin 2 (TT2) kit includes a round printed circuit board and all PCB mounted parts: transistors, capacitors, resistors, toroids, magnet wire and key jack. The kit also includes a 7.040Mhz crystal and SIP socket for easy crystal change. Assembly booklet also included. You have to scrounge up the can, PCB mounting hardware, antenna, power and receiver jacks, hookup wire and T/R switch.

This amateur radio club provides kits uniquely packaged in tuna tins. When you build the kit, the tuna tin also serves as a chassis for your new project, complete with a nice label for the tin. Although most of the kits are geared towards QRP (low power ham radio) operators, Make readers might enjoy the "AXEme Picaxe Construction Kit". This is a Picaxe development board built into one of the famous tuna tins. It's a very unique and eye-catching way to work with microcontrollers.

Alphacool Watercooling Starter Kit

Alphacool Watercooling Starter Kit. Ready to get wet?

Take a PC full of expensive, complicated, electricity-driven parts, add about half a litre of water in aquarium tubing and plug it into the mains electricity supply. Up until a few years ago many would have laughed at such thoughtless bravado, quoting the school-taught fear of lethal electrocution. Nowadays most enthusiasts are familiar with the concept of watercooling, but the sheer complexity of the systems and their installation can be mind-boggling to say the least.

Designer emulation kits - DEK2

these light can be transfer in to different forms..

The Designer Emulation Kits (DEK’s for short) are meant as the sincerest homage to some of the greatest modern designers of our time. The lamps and designers being “emulated” have a particular importance.
They are represented in countless design tomes extolling the various movements, and they are held up as prime examples of “good design.”

Laptop laser etching

For iPod (mirror-like reflective surfaces) we "etch" using an etchant chemical that appears black when laser etched


It can applicable on any type of surface!!

Bicycle wheel animations

Check out these incredible LED bicycle wheel animation using the SpokePOV kit. Mario scoring points, a running mouse, rock'em sock'em bots and Duck Hunt!

The spokepov kit includes electronic parts and circuit board for one basic configuration Road/MTB SpokePOV with 4K of memory (for 4 animation images) and 60 high brightness LEDs (30 on each side).

Available in red, yellow, green and blue. All colors can be used in MTB/road wheels (9.5" wheel radius minimum) and red and yellow in BMX (6.5" wheel radius minimum). The Pacman/Ghost image shows a yellow set and blue set of SpokePOVs. The Biohazard image below shows a set of red. One single SpokePOV fits in one wheel, you can add as many SpokePOVs to a wheel as you'd like get a better image. With one spoke, persistence at a speedy 15mph. Two spokes for cruising at 10mph.

Combat Robot

Goal number two is "battle worthy" construction. One of the keys to BioHazard's success is a bulletproof drive train that is completely housed in a square aluminum extruded tube.The one-piece extrusion (one each for the left and right drive trains), is precision CNC machined with mounting holes for all the sprockets, wheels, and motors. Each drive component is supported on both sides of the 3" x 3" square aluminum tubing to avoid "overhung" loads.
The tubing is made from 6061-T6 aluminum alloy. The feather and light weight robots have frame tubes with 1/4" wall thickness and the middle and heavy weights have tubing with 3/8" wall thickness. BioHazard, (a heavy weight robot), uses 1/4" tubing but we wanted to offer an even stronger drivetrain to stand up to your most destructive opponents.
The wheel assembly is made from the popular 4" Colson Performa tire. These are machined and mated to our custom hubs, bearings, and 19-tooth Chromoly sprockets. This combination weighs in at just 1.1 pounds - including the drive sprocket! We believe that this is the lowest-cost and lightest wheel/sprocket combination available. These wheels are included in all our kits but you can also order them separately.

Electric paper airplane launcher kit

This is a fun educational aid product designed to demonstrate scientific concepts taught in school curriculum. Ready for take off! Kit contains everything you need to learn how spinning motors and plastic discs are used to launch a paper plane at up to 31 mph (50km/h). An ideal kit for exploring paper plane designs.
This kit was designed at Middlesex University by specialists who teach teachers. Each kit is thoroughly researched and encourages young people to stretch their skills and thinking. Contains Base plate with guide, Plastic discs with pulley, battery box, motors, plastic rings (grommet), plastic suction cups, sticky pads, short screws, long screw, connecting sleeves x 4, terminal block, nuts, wire and screw driver.

The single-sheet paper airplanes you made when you were a kid (or perhaps last week in your cubicle) were, well, kid stuff compared to this beefed-up paper craft, which uses an electric motor from an old pager or toy powered by a big electrolytic capacitor. Known as a "Gold Cap" and made by Panasonic, the capacitor charges from a battery pack and then metes out a steady flow of power to keep your propeller whirring for about 10 seconds--just long enough to send the flyer airborne and carry it between 30 and 100 feet. (You can also add a gearing system to squeeze out even more flight time.) We've created plans for an eAT-6 "Texan" airplane and put them here and here to get you started. Just think twice before blindly launching this one soaring over the wall of your cube.

Cardboard rocketship toy!

The PaperPod Rocket comes flat and blank, ready to be decorated by your children. Ships from the UK and is too small for adults, so I think it's a perfect candidate for a re-make. I think I can reverse-engineer this thing from the photo... Nigel's Eco Store sells other eco-friendly holiday gifts as well!

AVR Oscilloscope clock

The AVR Oscilloscope clock from Dutchtronix was covered here @ MAKE before, but I finally got around to building one - it's great. Makes an awesome clock out of an oscilloscope. Not bad for $35... Above are some pictures from the build! It's not actually supposed to work on a digital scope, so this was an experiment - and it worked!
This AVR Oscilloscope clock is available as a kit, using all through-hole components. The kit included ALL components necessary to assemble the board shown below, including a preprogrammed ATmega168 microcontroller. It does not include an oscilloscope. It also includes connectors for the Power and RS-232 headers on the board. The user can use these connectors to build the power and serial communication cables
