Modding an NES – blue LED

This is the first of a series of old consoles modding posts, some to add functionality and some purely cosmetic. I will start with the simplest of them all, changing the power LED of a Nintendo Entertainment System.

When the NES came out in 1985, electronic power LEDs used colors that were available at the time, red or green ones. Blue LEDs were not around at the time. They were invented relatively recent and they gave their inventors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, the Nobel prize in 2014.

Changing the NES power LED to blue, in my opinion gives the 80s device a more 21st century feel and it’s super easy to do. All you have to do is unscrew the NES, remove the mainboard and get to the POWER and RESET board on the left. Use a soldering iron to remove the existing LED, while bending it a bit to the back to remove it from the plastic clear channel.

At this point you are ready to put the new LED in. Just be careful with polarity. LEDs, as the D in their name suggests are diodes, which means there is a correct way and a wrong way to put them in the circuit.

What Is LED? - Definition, Working Principle, Types, Uses

The LED symbol shows you the way. The Anode is where you need to use the long leg of the LED (positive) and the Cathode where you use the short one (negative). If you mess it up, it doesn’t hurt anything, but it will not light up, which is the whole point of a LED.

Solder the two legs at the bottom and bend the LED back in the clear channel like in the picture below.

If you get everything correctly and try to power up the NES, you will be greeted with a beautiful LED light. Put back everything and you should be done. Enjoy the 21st century light show!

New Surface tablets

So the new Surface tablets, Surface 2 replacing Surface RT (well, actually the original RT will stick around) and Surface Pro 2 replacing Surface Pro (duh). The Pro version looks like a powerhouse, awesome hardware with a few flaws (I would love to see a Retina like display on that thing and the price is REALLY high – get a high-end Pro 2, a battery cover and a dock and you are looking at $2,200 ffs) but at least batter life looks solid, which was my main complain with the original Pro.

The new Surface 2 though is interesting, since my previous post was all about my thoughts about that. Most of them were unfortunately not taken into consideration. The obvious ones that were actually done were the CPU power (the mention 3-4 times faster CPU but I have to use one to really see if that is the case) and mostly the don’t-throw-the-user-on-the-desktop-if-they-didn’t-specifically-ask-for-it with the 8.1 update since most of the settings are now on the metro environment. LTE is also supposingly coming early 2014.

The things they didn’t do from my suggestion list were kind of important too. Price seems in line with the previous Surface RT and no kind of keyboard is still bundled. Too bad, that would make the sale so much easier.

Another thing that I think should NOT happen is the availablity of the accessories which is all over the place. While the Surface themseves will be available on launch day, the docking station, car charger and power keyboard will not. Rather they will be available “early 2014”. Not cool.

In any case, the “blades” concept seems an awesome idea overall, with interchangable snap-on keyboard replacements for various functionalities, such as the music mix “blade” that was demonstrated. I hope they decide to open up the system for third parties to be able to develop “blades” for the Surface family.


This of course gave me an idea, for the ultimate “blade” that will end all “blades”. Please make it happen (click for larger):
