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.

Re-vamped Micro Mini Scooter (just for fun).

A Micro Mini Scooter repair, just for fun!

I really had no idea that Micro Scooters have been a ‘thing’ for the last few years and as a result, there are lots to choose from on the second-hand market.  We picked up a ‘bargain’ for our oldest daughter for a princely sum of £5.00 via a local Facebook For Sale page.  With hindsight, it was overpriced.

Just about every part of the scooter was either nasty or plain broken.  The handle bar grips were missing, the wheel bearings were all shot to pieces, the steering mechanism seized and the rear brake was missing.  The back brake on this scooter type, I’ve since found out, have a habit of snapping off with hard use, so that should have been the clue to the low, low price.  But if you read these pages, you know me, I like a challenge.

First step was to address the static wheels.  An Allen key holds the wheels on to the stub-axels at the front of the scooter and there’s something similar on the trailing wheel.  The bearings on our wheels were beyond a re-grease as they’d appeared to have spent their entire life at the bottom of The Channel.

Luckily, the bearings are easy to replace and good-quality generic items are available on eBay for under £5.00 for a whole set (6 bearings, 2 per wheel).

Next came the handlebar grips.  Ours were missing and again, generic ‘copy’ grips are available on eBay which are perfect for the job and are half the price of the original equipment.  While I was shopping on eBay, I also found an original Micro Scooter bell.  Just the job.

The steering mechanism was next and all it needed was a good clean up and light lubrication with some plastic-friendly white PTFE grease, readily available from Toolstation.

The shabby foot plate area was once baby-blue but had since faded and had evidence of scrapes.  It looked a bit sorry for itself.  I decided to address this by giving surfaces a good clean up and then key with wire wool.  A couple of coats of good quality plastic primer and then a couple of coats of vinyl black paint, which now gave the scooter quite a ‘presence’.  I then decided to improve the foot plate ‘grippy-ness’ by applying a custom grip tape design.

Before re-attaching the foot plate back to the chassis, the brake needed to be replaced.  As with some of the other fixings on the scooter, the brake’s fixings were so rusty, they needed to be drilled out and replaced.  Luckily the new original equipment brake came with new improved fixings which fitted perfectly.

I know what you’re thinking… for £40 more, I could have bought a brand-new scooter and saved myself the bother.  At times, I did question my own sanity.  But what we now have is a perfectly serviceable, one-off that no one else will have.  Can you put a price on that?!

Samsung S4 mini GT-i9195 -cracked screen

I take on a phone screen replacement

I’ve never replaced a phone screen before, but since there’s a wide range of spares at reasonable prices available out there, I decided to take on this repair for a friend.  The screens on these and other smart phones are fragile.  They are made of finely machined glass, made to extremely high tolerances and therefore susceptible to damage from knocks and scrapes.  At this point usually, I might whinge on about how manufacturers do this deliberately to some extent, to bolster built-in obsolescence, but on this occasion, the break was due to the owner falling off his bike (off-road) and the phone hitting the deck, while in his pocket.  I’m amazed the damage wasn’t worse.  No hospital treatment for the owner on this occasion, just bruising and a dent to his pride.

The repair kit for such damage came in at a reasonable £8.99 and the eBay vendor promises to have the kit within a couple of days.  I’m sure you’ll all be waiting with baited breath to know how the repair goes.  I will of course keep you all updated.

Stay tuned.

17/08/17

The repair kit has arrived and there are lots of components in the box.  After watching a few (very good) YouTube videos on the S4, I think I’ll need a clear evening to repair the phone…

26/01/18

Opening up the phone’s back, just a plastic over, only 1 small screws held the phone together as ‘layers’ sandwiched together.

After separating the screen from the main body of the phone, it quickly became clear that the screen was in fact OK and it was the digitiser (digitizer in the U.S.) that has cracked and failed.  This meant that a new one was required, but after a conversation with the owner, we decided that the phone was now beyond economical repair.  New digitisers are available for the S4 at the time of writing.   The phone will be disposed of using an electronic recycling scheme.
