Bagpuss, oh, Bagpuss, oh, flat battery cat puss…

A much loved soft toy gets new (apparently non-replaceable) batteries…

For a change, this one’s just for me. I don’t often write-up repairs on my own items, but I couldn’t resist dedicating a few words to our beloved Bagpuss soft toy. He’s been around in the family for a good few years and when my youngest daughter decided to dust him down and make his voice work, I wasn’t surprised when no noise came out. Our Bagpuss has an electronic voice box which is activated with a gentle squeeze around the belly. After many years and many hugs, the batteries had gone kaput.

I grew up in the 1980s and remember watching Bagpuss on BBC1. I must have been about four I guess. Bagpuss lived in a shop window, a shop that was owned by a child, a shop that didn’t sell anything. Emily, the shop owner, would bring Bagpuss and friends broken objects to restore and explore. The story would begin once Emily had left and Bagpuss woke up…

Well, this Bagpuss wasn’t waking up anytime soon and to make matters worse, the batteries within appeared to be non-replaceable. Well, that’s not very good is it? So, in the spirit of the original TV program, I decided to take an unpicker tool to the cat and carefully dismantle his seams…See how I get on.

There’s always that moment with a fix like this when you think; shall I just leave it as it is? I mean, it was still a loved toy right? But as my regular reader will know, that’s not quite how we do things in the workshop. Things must work correctly and if there’s a reasonable chance of success, then the repair must go on.

So, here it goes.

I knew that this Bagpuss ran on batteries, but had no battery compartment to gain access etc. He’s a soft toy, made from a mixture of polyester and cotton fabric, which is all neatly stitched together. All I could do is roughly locate the sound box within his chest and neck area and then chose a suitable seam to unpick, in the hope that it would allow me some access to the box without causing too much damage.

Using a standard stitch un-picker tool, I was able to gently cut into the neck and part of the chest area which gave me access to a small red and black smooth polyester bag, which contained the voice box. At this point, I was starting to feel a bit sick, I mean, what had I done!?

Moving on, the voice box just slide out of the red and black bag and from then on in, it was standard toy-fare. The plastic voice box had a switch on one side and a battery compartment on the other side, all perfectly normal. The battery door was held in place with a small screw and once removed, revealed three LR41 coin cell batteries. Very normal stuff, nothing non-replaceable here.

Luckily, I had some spare batteries in stock and with a little contact cleaner applied to the slightly tarnished battery contacts and the new cells fitted, Bagpuss’ voice was heard for the first time in ages.

Now it was just a case of putting the voice box back in the right place, so that the switch to make the sound work could be reached easily. Once that was done, it was just a case of carefully re-stitching the neck and chest bag together using white cotton thread and lots of neat tack-stitches that would be invisible, once tight.

After a few minutes of finger-pricking sewing, Bagpuss’ head was back on and it was time for a squeeze…

See what you think.

When a label or someone tells you that a battery cannot be replaced, ignore it and try anyway.

Once Bagpuss was back together, I couldn’t help but wonder why the manufacturer hadn’t fitted a hidden zip to allow simpler battery replacement. Perhaps it’s got something to do with safety standards. Who knows. What I do know is that Bagpuss isn’t alone, and I suspect that many toys like this are discarded needlessly each year due to short-term, lazy design.

Is 12 years too long to keep a toothbrush?

A Braun Oral-B electric toothbrush gets a new lease of life.

Let’s just clarify one thing straightaway; I’m talking about an electric toothbrush with changeable brush heads.

I was given an Oral-B/ Braun electric toothbrush as a birthday present years ago, which when you think about it, is a bit of a strange thing to receive as a gift.  Maybe the gift contained a hint?  Back then, these toothbrushes were not cheap, starting at about £60.00 if I remember correctly.  Today, a new equivalent is quite a bit cheaper.

In the time I’ve owned it, it’s had about 40 new brush heads and it’s just about to start it’s third non-replaceable battery.

Hours spent on repair:  1

Tools needed:  Small flat-bladed screwdriver, soldering iron

Sundry items: None

Repair difficulty:  5/10

Cups of tea:  2

Electrical items with non-replaceable batteries are so annoying.

A message to manufacturers:  There’s simply no excuse for it as all batteries are replaceable.

In my experience, items with ‘non-replaceable batteries’ contain entirely replaceable items.  The batteries might not be standard ‘AA’ items, but there’s a host of online suppliers that are ready to supply just about any power cell for any application, you name it, usually for a reasonable price that costs-in for the repair process.

Now, I don’t know how long one of these toothbrushes is meant to last, but as a long-term test, I thought it would be interesting to find out.  After the first battery died, I decided to take the toothbrush apart, to see what was going on inside.

As you can see from the photos, there’s more within than one might think.  There’s a switch, charging circuit, timer circuit, over-pressure circuit, gearbox, motor, mini crankshafts and a battery.  Not to mention all of the tiny connecting parts all neatly engineered to work together, reliably.  It’s a small work of art really.

It makes me very sad that most of these toothbrushes will end up in landfill, after a few years.

The designers had clearly designed this toothbrush as a disposable item as the battery, despite being readily available from spares suppliers, was hidden, out of sight, under all of the gubbins.

To extract the battery (a simple nickel cadmium item) a full dismantle was required, in this order.

  • Prise off the top collar
  • Prise off the bottom cap
  • Pull out the main mechanism
  • De-solder the main pressure switch, charging coil, LED, and some other joints,
  • Take PCB off of battery carrier,
  • Split battery barrier from the main motor area
  • Remember the polarity of the battery, negative near the coil (a misleading ‘+’ there)
  • Reassembly, with the new battery is the same in reverse.  See pictures for hints.

Twelve years down the line and now on its third battery cell, the toothbrush is still going strong which proves that with a little tinkering, disposable items can be repaired and made to last longer.

It’s just a shame that Braun, the manufacturer, decided to ignore any notion of consumer maintenance.
