I have this USB DAC/headphone amp
(which is great). I just started using the RCA outputs for a pair of powered monitors
(also great). The problem is that the DAC switches between the outputs based on whether the headphones are plugged in. This makes sense, but it's annoying. I want to hack it and switch between them manually. Electronics whizzes, check my reasoning. [more inside]

I inherited this rice cooker
but cannot figure out what buttons to use to make regular short grain Asian rice. I thought it was the large one on the right but the rice is gross and uncooked yet soggy. Can you help? I looooove rice and need to remedy fast. Thanks for your help. Can you tell me what all of these buttons mean? I can't find a mode number so I can't look up the operating instructions online.

I need basically this
I'd rather order it from closer to home. My searches for this type of cable in the US haven't turned up anything, and I don't know enough about electronics to figure out what other names it might go by.
I think it's a common type of cable so there must be something I'm missing.

Is it feasible to take apart, modify, and put back together again a hair dryer so that it works in reverse, that is, become a small vacuum? I assume I would have to make the blower work backwards to become a sucker, and I would have to direct debris into a little sack and away from the blower and power source. If I were going to do it, what would I do? How much work would it be? How ugly would it be, assuming rudimentary skills and a home workshop? If it's impossible-- why?

How do I safely and (pretty) cheaply implement this one-off home electrics / electronics project? I have a low-wattage controller that will drive a high-wattage load having to do with the heating of water. I already have a GFCI extension cord that will stand between EVERYTHING and the wall outlet. The main complicating factor is that this is a single, custom-built thing so I need to use off the shelf pieces for a housing, etc. [more inside]

Is there any kind of plate or bracket I could buy that would allow me to retrofit them onto a device that does not have them, without drilling into the device?

We have an alarm for a door that sounds constantly while the door is open. It is run from a 9v transformer that plugs into the wall and the circuit is triggered with magnets on the door. I would like to install volume control for the alarm. Is the correct device a potentiometer? If so, how do I select the correct one? Thanks!

It looks thusly
. My issue is that, despite the fact that it was originally barely taped down at all, I am unable to successfully, reliably
reattach it using the same method. ("it" in this case being the printed black strips on the left). I am reasonably sure that lack-of-contact is my problem, because if I physically hold the cable to the board, it will reliably work when I push a button.
Best I can do is that sometimes, after putting it all back together for the Nth time, one button will work. Maybe other buttons on its side will work, maybe not. Maybe it'll work for a few presses and then quit.
The cable looks fine, the board contacts look fine, no amount of scotch tape is helping me out here. How do I affix these suckers but good?

I want to use a timer (minimum on time is one minute) to turn on my coffee maker. The ON-OFF button on the coffee machine is a momentary contact push button which is read by a logic board. Can I use the (isolated) relay contacts on my timer to close that push button for one minute, the minimum on-time of my timer? [more inside]

Snail trails on Garmin Nuvi 255W. When out and about this device is now making pale blue 'snail trails' on the map tracking the car from A to B.
It is working as it should otherwise.
Does this mean that the device is on its way out? I checked some forums but could find any mention of this bizarre behavior.

How do I replace a blown woofer in a Spica TC-60
loudspeaker? The datasheet
is here. I am generally capable, but don't know anything about building/repairing speakers. Can I get away with replacing just the one? Is there any danger of damaging the crossover (whatever that is)? The very nice guy from Madisound
recommended a ScanSpeak replacement
but how do I know if it will fit and/or work properly? If I'm reading the datasheet correctly, the original seems to be 180mm in diameter, and the replacement he recommended 170mm - is this a good idea? How can I tell if there's anything else I should try? What, if anything, do I seem to be overlooking? Thank you!

My mother-in-law's old DVD player bit the dust recently and we would like to get her a blu ray player. She does not have internet and has a Magnovox 27 inch analog TV. She just wants to be able to view DVD and Blu ray movies.
Any recommendations on a good, basic player?

My 4.5 year old got to play with my friend's Ipod Touch, loved it, and is now adamant that Santa is bringing her one. This ain't going to happen. However, I would like to find her some kind of age-appropriate equivalent toy for Christmas. We don't do huge Christmas celebrations or massively expensive gift-giving, so this will be her big present, even if it's under $75. What can you recommend that won't make her ultra-disappointed (understanding that disappointment is a part of life, yadda yadda yadda)?
