How to Repair a Broken Maplin Radio Receiver RSL3660R-UK

These RSL3660R-UK units were originally sold by Maplin in the UK which closed down a few years ago now. They come with a little controller and you can control multiple power circuits using the same control so its quite handy. The radio receiver units themselves actually work really well and lots of the time when they stop working it is a common problem with the safety capacitor. Buying a replacement unit can be expensive and there is a way the majority can be repaired a lot cheaper if you don’t mind getting your hands dirty and can do some basic soldering. The first thing to check when problem solving is that the dial on the back of the plug matches the switch on the controller.

Now before you attempt to fix this please make sure you are competent and confident to do so. These plugs operate on 240VAC and can kill you or injure you if you do it unsafely or don’t put the casing back together properly.

First thing to do is lever off the plastic collar to reveal the screws. You should be able to put a small screwdriver under it where the screwholes are and pull up to remove it.

Now you are onto the hardest part, getting the Torx screws out! I found one of mine came out fine with the correct Torx screwdriver, it should use a T10 with security centre pin. The other had already been mangled by someone and I had real difficulty getting it out. In the end I managed to fit a small flathead screwdriver into the groves and push/twist to get it moving. Once it was out I replaced the screws with some new ones to save the next person the struggle.

Now you should be able to pull the case apart and get access to the circuit board.

The big yellow capacitor is the safety capacitor and the specs are Safety Capacitor MKP or MPX X2 0.33uF 250-275VAC. The capacitor has a 15mm pitch, you can try to bodge in other pitches as there it some room in the case but for an easy life go for 15mm. I managed to find my replacements on ebay.

Use a soldering iron to heat up the old solder and if you have one use a solder sucker to remove the majority of the solder around the legs. Once you have done that can heat the legs and it should pull free of the circuit board. Once you take the old capacitor out then you can measure the capacitance with a multimeter to confirm whether its broken or not, the correct reading should be 322nF or 0.33uF. There was no visible damage to the capacitor I removed but it was only measuring 83nF so there was a definite problem.

Once the new one is in then you can start putting all of the parts back together and give it a test with the remote once the case is fully assembled. Never plug it in and test without the case being back on properly.

Finally check that the switches on the plug and remote control are all set correctly then hopefully you will have a few more years of operation.

How to Break Down a Lost Mary QM600 Disposable Electronic Vape or Cigarette Into Components

Firstly, safety – The batteries can still carry an electrical charge and can be dangerous still so if you are not confident then I would recommend you put the whole thing into battery recycling rather than try to break it down yourself first. For those who wish to contine I have put a guide below on how I disassemble and recycle the Lost Mary QM600 disposable electronic vapes or Cigarettes I find.

First of all, get your tools ready, I use a couple of pairs of different sized Pliers, some snippers and a screwdriver.

Ok lets roll.

I start with the metal end cap, get some small pliers and either lever it off or put then through the hole in the top and pull. Don’t worry about breaking it, you are just going to recycle it anyway.

Now grab the plastic end part underneith and pull the guts out.

Now to get the main metal piece out of the plastic body grab the other end and wiggle it out.

Now use pliers to pull the rubber parts out of the end plastic part you pulled off.

Now we shall focus out attention on the battery. Remove the coat from the battery carefully with pliers.

Now snip the red wire away from the positive terminal.

Then the two black wires away from the negative terminal to free up the battery.

Now we just have some tidying up and separating to do for the other pieces:

I couldnt see a way to pull the component out without snipping the rubber part or the wires, do that and it should pull free.

Once you have done that everything should be nicely separated. Recycle the plastic and metal bits in your normal recycling. The battery can be taken to battery recycling, they have these in lots of the big shops and your council should have various facilities. The electronic part and wires can be put in the waste electrical equipment recycling (all councils have these facilities). The rubber is sometimes recycled but sometimes not. If not you can bin it with the fabric pieces.
