We have a foscam webcam with night vision and the works. We can access it via wifi on our phones and computers, but want a dedicated screen to use as a baby monitor. Portable and/or plug-in... what are our options?

I have a 9v battery powered water leak detector (this one: http://www.glentronics.com/water_alarm.htm ).
I'd like to open it up and replace the audible alarm with an led. How do I do that? [more inside]

What are these
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?

I have a costume helmet that I'd like to have a forced air ventilation system for. I would like a small, low power fan (maybe from a laptop or small computer?) that I can run on batteries. [more inside]

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]

I have a pair of Monster Inspiration
. I'm trying to play Madness by Muse
but if I plug the headphones completely into the iPod or computer, I can't hear the vocal parts at all. If the jack isn't completely in, then I can hear it perfectly. Why is this happening?? [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.

What kind of IC is this
? Picture shows a TO-220-3 IC with the label S9010, B5 and a manufacturer logo of a sort of stylized C. It is installed in the Q1 position so I assume it is a transistor. [more inside]

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)?

I need an easy, yet cool-looking electronics project.
In around one month, I'll be visiting Tokyo, including a day-long trip to Akihabara. Inspired by this post
I think it would be really, really cool if I spent part of that day buying parts in order to create something electronic. Difficulty: I have close to zero experience with electronics. [more inside]
