Power Cane for Disabled

“Necessity is the mother of invention” – English proverb

In the case of Gregg Teaby, watching his daughter, who had suffered a stroke about 5 years ago which left her partially paralyzed on her left side and in need of a cane, the need was evident: help his daughter get around more easily. Canes and walkers require the user to lift up the device to displace it, and so for a brief time their balance is compromised. Once the cane is in its new location, the user can put their weight back on it. For those who do not have full control over their muscles, or whose motion is restricted, moving this apparatus might be a daunting task in itself, reducing its usefulness. The motion of someone using a cane is far from fluid.

Greg & Celeste

Greg & Celeste

Gregg, a retired engineer, imagined a device which moved with the user and did not require additional unnecessary physical motion / stress, but was as lightweight and as small as possible. Hence, the “power cane”.

Several prototypes were build and tested. The latest iteration uses the Lynxmotion 2″ tracks. When building the track system he noticed the sprockets did not make for a very smooth motion for the user and he took it upon himself to redesign them, using his 3D printer to create proof of concepts.

Take a look at the video below. He has not commercialized the product yet, but is not in it for the money; he created the product to simply help his daughter and any others who have the same affliction / need.

Motorcycle GEAR Indicator (discrete components)

Posted: 01 Nov 2015 07:33 PM PST

It has been a while of not having to offer my readers on some stuff that they can incorporate on their motorcycles, but I am here now. The project is made a long time ago actually but halt the progress due to limited resources available in my country. Introducing a Motorcycle Gear Indicator using discrete components and no micro controller involve. Here, the circuit is made by logical semiconductors.

CIRCUIT DESCRIPTION:


The circuit is quite simple. It uses the power of the 10 line to 3 line encoder 74ls148 and will drive a 7447 seven segment controller to display the right number of the gear. I will not explain further on how they work, datasheets are available all thru here.

74LS148 datasheet
74LS47 datasheet

Combining this two and with the help of some resistor, a 5 volts regulator, capacitors and a Seven segment display, you will have a working gear indicator for your motorcycles.

You will also be needing this for not all motorcycle is equipped with it. A universal Gear indicator sensor. Suzuki raider R150 only have three pins of that i think, neutral and top gear only plus ground and must be replaced.

The sensor common pin is just an earth ground and when a corresponding pin touches one of the input of the encoder, the circuit will then display the number of the gear.
