Nintendo Switch Joy-Con stick replacement.

This is a small photo walkthrough about how to replace a Nintendo Switch Joy-Con stick. Seems to be a kind of a necessary thing when you step on your Switch's Joy-Con unintentionally and break the damn small thing... ;)

First of all, I bought a Joy-Con stick repair kit from Amazon. It comes with two new "non OEM but OK" sticks and an assortment of good quality tools to make the Joy-Con disassembly process an easy affair.

We have to open the Joy-Con and remove the four screws on the Joy-Con's back using the tri-wing bit. Then pry open the Joy-Con with the help of the plastic nail tool. Be extremely careful with the small ribbon cables that run from one side to another.

Once the Joy-Con is opened, we have to move apart the battery (attached to chassis using a small adhesive pad) and the antenna board. Next step is to lift the battery chassis by removing two screws located at each side of it. After that, we 're able to reach the backside of the damaged stick.

Now, to extract the stick we have only to remove two screws more and release the small ribbon data cable from its connector (using a pair of electronics tweezers). The sticks can now be swapped. It's necessary to reattach the small plastic shield from the old stick to the new one.

Remount the Joy-Con following all steps in backwards order.

To finish, check that the new stick works properly. It may be necessary to recalibrate the stick using the Nintendo Switch system menu.

Lesson learned today: Do not leave your Nintendo Switch Joy-Cons laying on the floor.


Nikko RC 6V battery pack rebuild.

Here are some photos and tips of the rebuild process of a Nikko RC 6V battery pack.

Beware! Do not try to do this if you don't know what you're doing. Batteries are not a joke. Wrong polarity mistakes and short circuits can lead to a fire or an explosion. Take the following information at your own risk.

I've opened the sealed battery case with the help of a Dremel multitool and a cutting disc. It is necessary to be very careful not to damage the battery cells when cutting the sides of the sealed battery case. Inside whe can found five 1.2V AA NiMh regular batteries tied together in series to get the required 6V.

Using strong tape and 5 brand new Amazon's 1.2V AA NiMh 2500mAh rechargeable batteries, I've set up the new battery pack (carefully taking account of original cell's polarity).

To make the cell links, I've used copper braid. Before welding the new links, I've prepared the surface of the poles by gently sanding and tinning them.

Protect the cell links with tape and weld the battery pads from the original pack. Be careful to not make shorts with other cell poles. Remount all in the original battery pack case. I've used more tape to secure all.

Ready to roll and recharge... ;)

Here are some photos of two modifications I've made to improve the amplifier.

I've replaced the old and rusty speaker terminals with some new golden plated banana plug terminals:

This amplifier do not have an AC input EMI filter, so I've installed one to reduce power-line interference problems.

Previously, I've removed the top cover and the aluminium front panel and knobs to access the inners of the amplifier. Over the many years of use, control knobs and front panel tend to accumulate a lot of grime and grease. To make the aluminium parts shine again, nothing better than wash the surfaces gently with hot water and neutral soap. Carefully wipe with a wet microfiber cloth, to avoid damaging the front panel lettering.

Remounting ...

... and testing.

After recapping, the sound stage has improved considerably. This little amplifier sounds really, really good.
