You can run a Sega Genesis off of a 9 volt battery I actually did this. Back in the day when I was in high school and we were doing finals. We were told we could bring something like a Gameboy as long as we had headphones. I asked if I could bring a Genesis is my English teacher I said as long as you got headphones a TV to play it on and a way to power it without plug it into the wall go ahead. So I brought a Sega Genesis with a 9 volt battery hooked up to it and one of them Sony Watchman. Hey my English teacher said he saw some weird-ass shit back in his day and this topped it. Also remember this was about two years before the Sega Nomad came out

[@sommor001]

FYI you can mix in parallel and in series connected batteries. It's not recommended without a voltage regulator, since not all batteries provide exactly the same voltage, even brand new ones. (The voltage of batteries will drop over time or by using them.) A correctly connected circuit will give you about double of game time and can possibly be infinitely expanded. Another solution to improve game time is to use a battery management system that automatically switches to another battery pack if it detects that the battery pack in use drops to a critical voltage. It's possible to expand game time by maybe 5-10 minutes if you connect the battery pack directly to the pcb, since the ac to dc converter does lose a voltage of about .7 on the diode. I studied electronics (not just in theory) a few years ago and even designed some custom audio pcbs. For safety reasons, you could solder a physical switch near the battery pack to prevent it from shorting out.

Batteries can be made with primitive materials and after a nuclear war you can still play with your Nes. (You can forget about more modern stuff.) Decade old pcbs (games, systems, etc.) can usually be restored by resoldering the connections and parts like resistors can be made woth basic materials.

Undervolting is a key component of circuit bending, you can get all sorts of strange reactions. Kinda interesting running the hardware lower than it's rated voltage to see what happens

[@pirateskeleton7828]

Can you put DC through a rectifier? Yes. Should you? Probably not, if you want to be efficient. By connecting the DC through the rectifier you are forcing it to go through an unnecessary diode which will eat up approximately 0.7 to 1V, depending on the diode, per diode. The plus side is that a rectifier will protect you from destroying your electronics if you were to connect it with reverse polarity. Also, keep in mind that the rectifier would normally be outputting a rippling DC voltage based on the root mean squared of the adapter’s stepped down voltage. As for the Nintendo having a voltage regulator that can handle up to 18V, my guess is they wanted a universal design that would work with US, European, or other international voltages. It is probably using a buck converter to drop the battery, so your best bet for performance is a voltage in the middle of its range. It will not get hotter with higher voltages. Conversely it will be more inefficient with lower voltages. All that being said, good experiment. If you have any questions, I’d be happy to answer.

[@CotyRiddle]

diode don't eat the voltage the drop the voltage. so you basically loose some capacity just from the voltage drop. and there are 4 in the nes so you actually drop almost two whole volts. the nes only needs 5 volts to operate a total of 6 to run the rf circuitry.

[@pirateskeleton7828]

Coty Riddle I hear what you’re saying, just keep in mind that the voltage drop is still being dissipated as heat, thus being consumed. I wasn’t sure if the console had a full bridge rectifier, so as you said, that’s an even worse power loss. 👌

[@CotyRiddle]

@@pirateskeleton7828 yes its full bridge. four discrete diodes wouldn't want to send half wave into that :D.

[@ky5666]

The NES existed before switching power supplies were invented or made cheap enough for consumer electronics (not sure which applied at this time). It actually uses a 3 terminal linear regulator. See 6:10. You can see the TO-220 7805 regulator hanging upside down from the RF pcb attached to a large heatsink.

[@pirateskeleton7828]

Kyle Mayer 7805? I did not notice that. In that case, higher DC is definitely not better, though if I was to mod it, changing it out for a switching power supply would be one of the first things I do, provided the switch freq doesn’t mess up the timings or cause any other interference. Would probably want a large filter cap.

An easy way to double the play time would be to get twelve batteries and do a series parallel circuit, in the same way that a parallel connection works, you can take two series "battery packs" and use its outputs and wire it in a parallel circuit to have 9 volts but with the capacity of two batteries in a parallel circuit instead of just a single battery, and you can continue to add more packs of 6 batteries in series to the parallel circuit to increase the total capacity.

[@MikinessAnalog]

I actually tried this before, knowing a full wave bridge rectifier will pass DC through 2 of the 4 diodes it has, but for some reason, the 9 volts @ 1 amp did not power it up in either polarity. I am actually surprised yours worked for you. The only way I could get it to power up on DC was to literally solder 2 wires to the board opposite of the main power filter capacitor, but the NES is built so modular, it is easy to disassemble and reassemble.

[@EvenTheDogAgrees]

Well, this is what you'd observe, but it's not the explanation. The actual explanation is this: you're measuring the open-circuit voltage, which is not the same as the voltage under load. Connect any load to the batteries, and the measured voltage will immediately drop. The heavier the load, the bigger the drop. Disconnect the load, and the voltage rises again. It's a thing batteries do. Someone who actually understands the chemistry (so, not me) would probably be able to explain why this happens.

Your 9.89 volts is actually a little low. When rectifying AC to DC, you need to multiply the AC voltage by 1.41 to get the DC voltage, so with a 9v AC adapter, you will see around 12.7VDC on the DC side of the rectifier. When running DC through the rectifier, you will see the incoming DC voltage, less the forward voltage drop of the conducting diodes, so you could safely feed 12VDC into it all day long. A 12V sealed lead acid battery worth work great.

[@LOLMAN9538]

Do you mean we're using a FOOL BREEDGE RECTIFAIYA to convert the AC input to DC? (yes, I watch ElectroBOOM regularly)

[@skipfred]

No, you multiply by 1.41 to get the *peak* voltage. You will still get ~9V RMS (minus diode drop) on the output side if it's unfiltered. The NES is filtered so you will get a roughly steady DC voltage of 9V minus two diode drops.

Although a rectifier rectifies the AC current in to DC it brings some kind of voltage change. It's the same how if you rectify 120v AC you get 170v DC. Although it is also dependant on the types of components you are using to do the rectification. Also if you want more power you can use 12 batteries. Make two sets of 6 batteries and put them in series, then connect the two sets in parallel.

Would be cool to see some more of those battery compartments wired in parallel for longer lasting battery

[@seltzerbot8730]

Thanks for actually showing what happens when the console runs out of battery power. That was super cool

[@trevorgray3681]

My dad and I did something similar years ago with a 9v battery.

[@philiphanhurst2655]

Batteries do drop in voltage as they're used. This is actually how the amount of stored energy left is measured.

[@coaxgaming2547]

@Phillip_HanBurst THANK YOU, this is the proper equation: 850x9/60x850=108 (AKA 1h and 8mins) for the lifetime or an easier way to think of it: MaH Rating(X)Input Voltage(/)1 Hour or 60(X)or(/)Output Load = Rated Discharge time before none operational What you Calculated(MattKC) is for how much battery is left? even @Phillip_HanBurst Noticed, anyone else NOT gonna ask why he calculated the Power Left in the battery? he litterly did 850/850=1 (You didnt even use any time calculation) sideNote: you divided 850 by 850 XD?

I ran my Atari 2600 off a 9 volt battery years ago. I just used the right size power jack for the Atari and a 9 volt battery clip. Worked great and for a pretty long time.

[@kargaroc386]

If you look at the BW image, you can clearly see the color signal subcarrier as part of the BW image, appearing as cross hatching. I *think* that, as the voltage dropped, the system clock frequency started drifting. The same clock is used for the color subcarrier, and the NTSC/PAL standards are very strict its frequency, so if its off by only a little bit, the colors will either be wrong or just gone entirely. The static in general probably comes from the signal strength of the video output decreasing as the voltage drops. More and more of the signal ends up below the noise floor, so when the TV's AGC turns up the gain in response, you see more and more noise. The CPU/PPU glitching is straightforward.

[@Sevent77]

You should turn this into a series on what systems you can run of batteries.

[@awilliams1701]

all of them. It's just a question of how many batteries and does it require bypassing the normal power plug in some complicated way.

[@sune9578]

Ashley Williams is correct. All of them. We can even go further and say *all* electronics can be powered by batteries (some would require some additional help, however (like capacitors or whatever)). It just simply becomes a matter of economics and practicality at that point.

[@thorn9382]

How do you not have more views?

[@pedoboys]

You're profile pic says it all

[@linuxguy1199]

2:60 This really depends on how you define capacity, if by capacity you mean current capability (amp hours) then yes. However in terms of actual power generated then no, in both cases the total power output would be 9Wh (assuming each battery is 1Ah @ 1.5V).

I'm enjoying the classic tracks in the background. 1. (I knew this but I forgot, the title read "Dance Music") 2. ? 3. Rain Eater 4. Contraduct Design 5. Spock's Cryo-Bed 6. BRD Keygen 14 (LHS/DFS) 7. ? 8. ? Let me know of other songs I didn't identify correctly.

[@matani2001]

7. Class Cracktro #5 (Maktone)

[@irritated_name]

I'm not sure of the order, but I know one of the songs is Space Queens from Sonic Xtreme

[@brixt0n]

That maktone track.. memories

[@flatfingertuning727]

Most of the circuitry in the NES operates off 5 volts, but if memory serves some of the color circuitry uses nine. If one were to modify the power supply input circuitry to replace the linear regulator with a switching power supply, that would probably extend battery life by about 30-50% when running off six AA batteries, and allow further improvements in battery life by using eight AA batteries instead (switching power supplies draw less current when their input voltage is higher). Some clone consoles might also offer much lower current draw than a 1980s Nintendo console.

[@computerkiller1494]

6:04 a full bridge rectifier will take off 1,4 volts so the electronic is safe, also the house voltage is not PERFECTLY 220V or 110V so there is a voltage regulator + the electronics are projected to rexist to like 1 or 2 volts out of normal.

[@intel386DX]

yes you can end the bast way is to connect 5V directly after voltage regulator 7805

[@kevinfrazier1692]

I appreciate the inclusion of "Space Queens"

[@TechnologistAtWork]

You could always do 6 batteries in series and pair them up with another 6 in parallel for more amps per hour.

[@mr.papaveraceae3009]

Man, didn't expect it to get emotional. Felt like watching an NES experience what death is like. At the same time, would be curious to see an AC adaptor with a pot dial resistor to find what is the minimum voltage you can have to run an NES. OR at what point does the circuitry lose the ability to filter color.

[@Gerenocidiac]

I have some 1.5v rechargeable AA batteries (most rechargeable are 1.3v I believe so be mindful of that) that could save the cost over time issue for this. Still, needing to use 6 (or more, as the 1.5v rechargeable AAs have less mah than the lower voltage option) would be annoying and would need to keep 12-24 of them on hand, and charged. Neat seeing how the voltage dropped affects the image output too.

[@lorenbufanu1639]

When I was about 10, I was very annoying about losing the progress when electricity goes off, a thing that was very common in my country. Then, I have used 5 aa rechargeable batteries to power the unit when power goes off. A diode and a resistor( for changing). Worked about 3 days before needed a recharge. Great times
