A Star Trek Next Generation themed money box gets a light restoration

Some things are just cool.  I mean look, if this money box doesn’t encourage prudent saving behaviour, then quite frankly, nothing will.

Spoiler alert:  Put money in, some of the Star Trek crew (Next Generation) light up, followed by speech and cool sound effects.  What’s not to like.  Pressing the Star Trek (Starfleet) button, simulates the effects too. What fun.

This money box had once been cherished by its owner, but had been left in the attic for a number of years, with the original batteries still fitted.  As anyone who’s done this before will know, old batteries leak in time.  If you’re lucky and catch the ensuing corrosion in time, you might get away with just battery removal and a light clean up. If you leave it long enough, like the owner of this toy had, you’ll end up with a lot of rusty mess and no chance of life (Jim, but not as we know it). Remember, take batteries out before putting your toys away, long term.

When I get an item like this, I tend to spend a bit of time researching it online, to see who knows anything about it.  It turns out, that this money box isn’t that well represented and after a few Google searches, I simply gave up and got on with the repair.

Parts for something like this are not available from the manufacturer, even if they are still around.  Presented with a situation like this, the only thing that can be done is to see if other parts can be bought off the shelf from component suppliers and be made to fit.  One simply has to be creative.

Good old eBay came up with the goods.  AA and C type battery terminals were available in single and double terminal variants and I ordered a couple of packs from a Chinese supplier, who delivered the bits I needed, within a week.  These things are reasonably cheap, so I ordered a pack, just in case I ruined a few, practicing first.

Just a few small screws hold the casing together and after de-soldering the wires going from the battery compartments to the main circuit, I was ready to start.  With battery corrosion as severe as this, all you can do is soak the parts in something like WD40 and attack the rusted parts with a small screwdriver and knife, taking time to avoid damaging the (aged) plastic casing..

After an hour, I’d removed 99% of the mess and fitted the new terminals.  The AA terminals went in OK, but the C type ones needed adapting with some metal I had lying about in the workshop.  A quick re-attachment of the wiring,  a quick clean with brake cleaner to de-grease and then touch up with some satin black paint and one would never know that batteries had ever wreaked such havoc.

Sometimes, I want to hang on to some of the things I repair.  This was one such item, but alas, I had to give it back.

Time for a brew.

Non-starter: Pure Evoke H2 DAB radio

My own radio gets the workshop treatment.

Who wouldn’t love a new DAB radio for your birthday?  Well, that’s what I had this year and I was thrilled to receive this Pure Evoke H2.  After choosing a suitable location on my desk, I quickly unpacked it, plugged it in and…nothing.  Booooooo!

The display backlight appeared to glow a little, but that was it and I was missing Today on Radio 4.

To save a quite frankly dull story, the returns and replacement process offered by the company who supplied the radio was hopeless.  But, after 2 months, I ended up with a replacement radio, in addition to the one I already had.  The second radio worked, albeit with some fettling required to the speaker to make it sound ok (another story).

Time to dig out the screw drivers as I had nothing to lose.

Just 6 screws hold the back on and with these removed, the radio’s innards were exposed.  Now, I’ve made radios from kits in the past using components I can hold with my fingers, but with this radio, the circuitry was teeny-weeny and I would have to have some luck to fix it.

I was in luck.  The radio is made up like a sandwich.  The front fascia is screwed to the cabinet and the back, that I’d removed, was screwed to the cabinet, from the other side.  There are data-style cables between the two halves and one of them appeared to be loose.  I carefully pushed the connector ‘home’ and then re-applied the power lead and wouldn’t you know it, the display lit up and it burst in to life.  Now we’re talking.

Thinking I’d sussed it out, I screwed the radio back together and had about a week or two of unbroken service, until the screen froze and then nothing. Oh no.

Re-opening the back of the radio, I suspected that the tiny soldered pins on the back of the multi-way connectors on the data-style cables, had been dislodged.  I have average sized hands for a bloke, but I needed tweezers to get the connectors on during assembly.  I wonder how much it would have cost to add an inch or so to each cable, to make manufacture easy.  As a consumer, I would have gladly paid the extra penny.  I suspected that this is how the original fault came to be as it wouldn’t have taken much more than a shove in the wrong direction to break the delicate connectors, due to the short length of the internal cables.

Since this circuit board is a tiny stamped component affair, I had to be quick and neat with my re-soldering.  Each pin to PCB connector re-soldered, cables re-attached, back screwed back on and the radio worked once more.

Pure have a reputation for easy to use, excellent sounding products.  It’s just a shame they have seemingly penny-pinched on some of the internal gubbins on this model.  If yours develops similar symptoms, don’t give up, take the back off and have a look.

Cost of a new radio:  £40-90.  Cost of repair:  5 mins tinker time, one cup of tea.

V-Tech Splash & Sing baby bath book

This toy wasn’t singing at its best…

My daughter was kindly given a V-Tech Splash & Sing baby book and always enjoyed singing along to the music it made.  It’s a splash-proof book which is suitable for bath time play, but not necessarily for complete submersion at 100 metres!

FixItWorkshop, Sep’17, V-Tech Splash & Sing baby bath time book.

It’s a battery operated toy and has an on/off switch and volume control on the front.  If the middle page of the book is squeezed in a couple of places, there are small switch buttons inside the book page itself, the corresponding the tune changes, relating to the picture on the page- I hope that makes sense.

The tunes on this book stopped changing with button presses and it became annoying to here the same tune constantly being played at bath time.  Very annoying.

The casing is held together with a few Pozi-head screws and after a bit of wriggling, the pages came free from the spine (the bit with the batteries and on/off switch).

Upon testing, the wires between the pages and the spine had broken internally and no longer connected to the corresponding page buttons.  They’d probably broken as the pages were turned over a good few uses.

This toy is definitely not designed to be repaired.  The only way to get to the wiring was to cut open the page, cut out the damaged wiring and replace it with something a bit tougher.  The previous wiring was very flimsy and it would only be a matter of time before it broke, too soon.

I decided to use some thin gauge speaker cable, the sort you find in cheap portable radios for the repair.  This worked really well and after some careful soldering and gluing of the cut-open page, the toy was ready for reassembly.

This repair probably wouldn’t cost in, in the real world, but I hate extreme built-in obsolescence and this toy showed examples of it.

Cost of the toy, circa £14.00.  Cost of repair; my time plus some old wire I had lying about.
