The Atari 2600 power supply wasn’t as durable as the rest of the Atari 2600, which is nearly bulletproof. By far the most common issue with the Atari 2600 is a dead AC adapter. Fortunately, a suitable Atari 2600 AC adapter isn’t hard to find, even today.
After you replace it with something new, or at least newer, a dead Atari console usually springs right back to life. And if you’re wondering, the same problems apply to Atari 2600 clones like the private-label Sears Video Arcade and the Coleco Gemini and they can also use the same replacement power supplies.
Electrodroid is an Android app designed for electronics hobbyists, but it has uses for model railroaders too. Its LED calculator is invaluable when using LEDs to light buildings, cars, locomotive cabs or headlights, or for other projects. Knowing the input voltage, you can then determine what resistors to use to protect the LED.
The voltage drop calculator is useful too, if less obvious. Read more
I saw a thing on Slashdot this morning about water-cooling your power supply. One word: Don’t.
I’ve worked inside a power supply twice–both times to replace a dead fan. One time I touched a heatsink that picked up a charge from somewhere–either a voltage regulator or a capacitor. Anyway, it really didn’t feel good. Beyond that, it made me jump.
Not a project you want to undertake if you don’t know what you’re doing. And if you do know what you’re doing, you probably already know it isn’t something you want to do be doing. Anyone who uses the word “electric” to describe something pleasant has obviously never experienced anything electric flowing through them.
I’ll pass, thanks.
