Bike2 – Chainless Electric Bicycle

at 3:59 pm. Filed under Cool Gadgets

Interesting concept, lots of the bikes we see today are mechanical bikes first with some add on electronics and motors that make them electric assisted. The motors are normally hub motors that are mounted within the wheel(s). The electronics connect to the brakes to sense when the user is braking and has a throttle to power the electric assist motor. If the battery is dead you are still able to use the bike as a regular pedal power bike. The Bike2  is a true electric bike first and has bike pedals available to simply generate electricity that can charge the batteries. Great concept but I wonder how it feels when the battery is dead or even if you can ride the bike with a completely dead battery. I think a regular bike rider would find it awkward at the beginning since the revolution of the pedals would not correspond with the speed of the bike.

“BIKE2 incorporates state of the art components for uncomplicated great technology at your fingertips (toe-tips), ergonomics and design. The system consists of innovative drive system components and is compact, silent and comes with a programmable interface for different speeds and cadence.
The absense of a chain allows different types of frames and customizable structures.”

Digital Caliper Data Plug Build

at 12:14 am. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Bob over at Making Stuff didn’t want to purchase an expensive cable for his digital calipers, instead he decided to build it. A small 3D printed grooved part with a few connected wires is all that is needed to connect to the data output port of the calipers. A logic level converter is needed to change from 1.5 volt output of the calipers a voltage high enough for a solid logic level 1. Now this can be used as a precision measurement input on a microcontroller project.

Laser Transmits Audio Over 100m

at 4:24 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

If you are looking to send some data or some audio over a fairly long distance wirelessly you can have a look at this very cheap solution if line of site will work. Iforce2d is using a very inexpensive laser diode and receiver to get the job done. This code is what does the heavy lifting as far as getting the data across the link.

5-Axis 3D Printer

at 10:06 pm. Filed under Cool Gadgets

 

 

Enomoto is developing a 5-Axis 3D Printer which will be for sale in about a year. This will change much in the 3D printing world since there were limitations that were imposed from the regular elevation printing style. Since the platform is able to move the printed piece in any angle very complex parts that were impossible before can now be built.

Table Tennis Trainer Project

If you enjoy table tennis this trainer might be a great next project. Thomas Mayer created this as his bachelor thesis project. Two Playstation CL-eye cameras are used to view the play area and track the ball. A project is then used to display game elements that the players can interact with to play many game scenarios. The game was created using VVVV which is a visual/textual live-programming environment for easy prototyping and development.

“The basic idea of my bachelor thesis was to track the ping pong ball in realtime to create data visualisations for trainers and players. After a few weeks of working I started developing a projected mapped interface for the ping pong table to show the collected data. By projecting game obstacles on the surface I figured out that I can change the game play totally.”

Mechanical Television Build

at 2:56 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks


 
 
Ben Heck and his team built this Mechanical Television. It uses holes drilled into a vinyl record which is spun with a light source behind it. A light sensor is then used to determine the amount of light that is reflected off the surface of the item that they would like to transmit. A complimentary rotating disk with a controlled light source is used to duplicate what the first system is seeing. The build didn’t quite work in the end but the techniques and information that we see along the way is worth it.

 

 

DIY Volume Control Builds

If you are tired of reaching for your tiny volume control knob to adjust your music when using your computer look no further than these projects by Engineering Nonsense and DIY Perks. The top one uses a DIGISpark board and a rotary encoder to adjust the volume via USB and the one below uses a potentiometer to adjust the analog output of your signal feeding your amplifier.
