Bionic Prosthetic Hand Suited To The 21st Century

bionic prosthetic handI listened to the BBC Radio 2 Jeremy Vine show on 23rd June and heard a great article about a young woman who had been given a bionic prosthetic hand suited to the 21st century. Her name is Nicky Ashwell and here she is in the following video tweet being interviewed by Jeremy Vine who went on to receive this bebionic logo handshake.

Note: The embedded video below is not of the same quality as the one seen in the original tweet direct from twitter here.

In the featured image, taken by Alex Lentati (@alexlentati), you can see Nicky delicately handling a flower with her bebionic logo hand.

Today I have found another article about Nicky and her ‘bebionic’ hand through twitter at Gizmag.

Below you can see a video demonstrating the various grips this hand, made by The Steeper Group, can perform.

Magnetic Levitation Using Superconductors

Magnetic Levitation Is Demonstrated Well In This Video

Apart from demonstrating magnetic levitation, using a superconducting magnet levitating above and below a Möbius track plastered in neodymium magnets, this Royal Institution (Ri) video also gives a good demonstration of eddy current generation in a copper pipe when a bar magnet is dropped through it.

If you didn’t catch it in the video the little superconducting magnet is made from yttrium, barium and copper oxide (YBCO) and is super cooled using liquid nitrogen.

See more Ri videos here.

Using A Bread Maker – Panasonic SD206

Introduction

I made this video of myself using a bread maker (Panasonic SD206) in 2001 but had no means of publishing it back then. So I have decided to publish it now so that the effort wasn’t completely wasted.

I hope it helps people who are considering getting a bread maker but are not sure how one is used in practice. Continue reading Using A Bread Maker – Panasonic SD206

Connection Points For Kitchen Appliances

Introduction

Everyone has to design their kitchen or utility room to suite their circumstances but when my kitchen came up for renewal in 2003 I made specific use of the considerable space behind my pan drawers. I discarded my pan drawer carcase back panel and brought together many of my connection points for kitchen appliances onto this large area of wall space behind the drawers, as shown in the featured image.

Giving A Dog A Tablet

DISCLAIMER: I made a unilateral decision to administer tablets to my dog by this method and he did not come to any harm. Before attempting what I have done here you should consult your veterinary for advice. I take no responsibility for any harm caused to other animals by using this method. If you don’t like it don’t do it.

A Worming Tablet

If you have ever tried to give medicine to an animal you’ll appreciate how hard it can be giving a dog a pill or tablet. Our dog Leo (a Border Collie) is required to take two worming tablets every three months. These are large as tablets go. Large enough to be shaped like a bone. My wife offered one to him. He sniffed it and walked away.

Why aren’t they supplied inside some meaty treat to encourage a dog to just woof them down?

Riding The North Norfolk Railway

The North Norfolk Railway

The North Norfolk Railway (NNR), known as The Poppy Line, runs from Holt to Sheringham via Kelling Heath Halt (for Kelling Heath Park) and Weybourne. A total distance of 5¼ miles. My wife, dog Leo and I road the rails there and back from Holt on 10th April 2014.

You can No.76034 having recently arrived at Holt in the featured image here.

The line runs along the part of the North Norfolk coast but stays inland from Holt to Weybourne. After Weybourne it runs nearer the coast on its way to Sheringham. A map of the line is available at http://www.strollingguides.co.uk/ and the line is  highlighted here on Google Earth (which must be installed to see it).

Mira Shower Thermal Switch Replacement

Introduction

This article advises how I have replaced a Mira Shower thermal switch in a MIRA Sport 9kW Thermostatic Shower on several occasions.

Originally I installed a MIRA Sport 9kW Thermostatic Shower as part of a new bathroom and had it tested and certified by a qualified electrician on 1st May 2007. I was very pleased with it and it worked well for three years until June 2010 when it developed a fault.

I found that in the middle of taking a shower the water would go cold for a few seconds and then get warm again. On the first few occasions I wondered if cold water being drawn off by other taps1 and appliances was lowering the water pressure to the shower and so causing it to operate incorrectly (although the low pressure light was not illuminating). As the days went by the problem got worse and my wife ended up washing shampoo off with cold water. I knew then that I would be in bad books until it was fixed.

I had to determine if this fault could be fixed or if I would have to replace the entire shower unit. For this I needed to take a look inside the shower unit. Continue reading Mira Shower Thermal Switch Replacement

Tiled Bath Panel Construction

Preface

I could write an article about ‘Building A Bathroom’ or ‘Tiling A Bathroom’ but I have decided to just cover a ‘Tiled Bath Panel’ in this article even though some detail of the tiles on the walls is mentioned. Bath panels can easily be made from painted hardboard or plywood, or boards, but a tiled panel can fit in with the rest of the bathroom very well when all the walls are tiled.

Introduction

In 2005 I began a project to build a new bathroom in the same small room as the existing one. The bath had to be in the same place as before because it is the only place it could fit.

Why have a tiled bath panel? The choices were:

  • the moulded plastic panel offered by the manufacturer,
  • a plain painted wooden panel,
  • a panel made of horizontal or vertical boards finished with paint or varnish,
  • a panel finished with tiles to match the bathroom walls.

Dishwasher Rinse Aid Dispenser Catch Repair

Introduction

It must be nearly two years ago that I first had a problem with my Dishwasher Rinse Aid Dispenser Catch. The tab that has to be pushed towards the top of the door to open the rinse aid dispenser, so that more rinse aid can be added, had somehow broken and disappeared. I found I could continue to open it by pressing the remaining catch towards the top of the door using the handle end of a teaspoon.

Since refilling the rinse aid dispenser doesn’t happen everyday I was happy to continue with that opening method indefinitely. However about six months ago I found the entire catch was missing leaving the rinse aid dispenser door flapping in the breeze. I searched inside the dishwasher and found the plastic part of the catch but not the coil spring. Also when I inserted the catch its retaining clips no longer wanted to spring outwards and perform their retaining action. The whole plastic catch appeared to have been eroded by the dishwashing process. I noticed that the dishwasher liquid dispenser catch looks similarly eroded, but that works on a different principal and is still O.K. The detergent and rinse aid compartment covers are made of a different plastic which has not shown signs of erosion.

After several months without using rinse aid I decided I should take action to fix the catch. Continue reading Dishwasher Rinse Aid Dispenser Catch Repair

Sighting A Straight Line

Introduction

I would say sighting a straight line is a common practice used by builders and joiners to determine if a piece of timber is straight or bowed. It can be used to test any length of timber, but long pieces in particular, and requires no tools just eyesight with a good depth of field enabling focusing along the whole length of timber to be checked.
