1202 ALARM

So when I was replacing the broken USB connector on the Samsung Galaxy Tab I managed to get a bit too much heat onto the main board and melted the lens of the front-facing camera. This was really stupid because I could have easily removed the camera before doing the soldering. I think the tin foil might have worked against me here. This is the old camera module with the lens removed, it still worked, but was pretty useless. I raided the broken bits box and tried a couple of web cams from an old netbook and 'phone, but couldn't get a lens that would fit, so I just bought a new one on eBay for about £12. I went the whole hog and bought a rubber bump case and screen protector for £10 because I liked the rugged look of the thing. The case is a nice one my wife got me for Christmas with a classic version of the periodic table on the front and a matching notebook. I stiffened the case with a piece of foam board behind the tablet for a bit more protection.

A nice HP laptop I was given by another kind Freegle user which had stopped working. It is about 4 or 5 years old and nicely specified for running Linux Mint with 4 GB of ram and a fast multi-core Intel processor running at 2.2 GHz. The guy's kids had been using it and it was covered in colourful stickers, which was cute, but it was also full of dust, probably because the kids had been sitting on the carpet to use the computer. This is really common and you see the same with Playstations and XBox consoles because they are usually put under the television on the floor. The computer was reporting a fan failure which a bit of research turned out to be very common for this model. The fan sounded like it was on its last legs, so a full strip down was needed, then a serious clean out to remove all the dust and finally a replacement fan off eBay for about £4. The keyboard wasn't great so I got a new one of those as well for £7, total cost of parts £11. I car...

This was one of the hardest repairs I've ever attempted. I got this lovely Samsung Galaxy Tab E (9.6-inch screen) from a kind Freegle user. It was dead, but a good look showed up that the micro USB socket was broken. I stripped the tablet down following a couple of useful YouTube videos and got the main board out. The only way to really work with surface mount components is using an SMD re-work station, a kind of soldering iron using hot air. I don't have one of these, but I do have my trusty B&Q hot air gun for plumbing and paint stripping. This is way too big for this work, but by wrapping the circuit board in tin foil and using the gun on the lower setting I was able to get the old USB socket out. I soldered 2 wires to the power contacts and partially re-assembled the tablet.  The tablet has intelligent charging and due to the odd connection it took about 12 hours to fully charge, but when it did the tablet booted up and I was able to do a factory reset and log ...

We have had one of those pop-up gazebos for a few years, very handy for barbecues and picnics and so on. Unfortunately, it got caught in the wind last week (my fault, it wasn't fixed down securely) and as my wife and son tried to get it popped down one of the struts snapped. There was a bit of damage to a couple of the plastic corner pieces as well. Not too difficult a repair although I couldn't find any scrap tube with the same oval profile so I used a round piece and crushed it at the 2 ends and middle. The damaged corner pieces are okay for now, a couple of cracks, but I replaced the self-tapping screws with nuts, bolts and washers. The repair worked out so we should get a bit more use out of the gazebo. We just need a few more good sunny days for more barbecues!
