Reconnect the Batteries

With a new baby, we are gaining an astonishing number of battery-powered devices - bouncy seats, swings, activity jumpers, mobiles, ... - And burning through even more surprising number of batteries. Now I know why Costco sells huge packs of AA. My wife asked if I could connect an dell inspiron 1501 adapter from the laptop to our mobile baby. I saw an article about modifying CREA noisy toys, so I knew it was possible. Turns out to be surprisingly easy, provided that (well, me) does not make dumb decisions on the road.



NOTE: The project that I describe, will void the warranty on any toy that change. The manufacturer (rightly) does not help or provide assistance to do this. If it works, be happy: If you can not open it, You Do not Own is. If not, take it as a lesson not to meddle in the affairs of Corporations, for they are subtle and quick to anger.



1.This guide is incomplete



You'll notice that two of the steps do not have useful images. I started writing this after completing the project in one of the motives of our daughter, and before starting the second. I definitely do not want to take the first apart again just for some photos, and have already decided not to d ...





2.What to change? A mobile

First, choose the product you would like the power of the wall. I'll show you a very nice boy Tiny Love mobile. The steps are similar for any device you choose, although the internal details (and perhaps screwdrivers) will be different.



3.What do you need? Parts & Tools

The parts you need to add an AC adapter (dell inspiron 1501 battery, HP Pavilion AC adapter) are fairly simple, but harder to find than expected. I ended up going to Radio Shack - that carry specific adapter voltage, individual counseling and panel mount sockets to match the ends. In most places you have a "universal" adapter, and can not get.

4.Open box

Remove the batteries first weld of the battery terminals in place is not the best idea. Open the phone using the triangular bit on the four rear panel screws. Be careful when opening the phone, because the cables inside does not have much slack. Identify the red (+) and black (-) ...



5.Prepare and mount-making



Drill the 21/64? (5 / 16? More than a little) hole in its brand to the AC adapter jack. The threaded end should protrude from the wall enough to tighten the nut. You may need a little extra clear plastic from the inside to take to fit snugly against the curved surfaces ...



6.Move existing cables

Disconnect the red and black wires from the terminals of the battery using the soldering iron and solder-pumping if necessary. Be sure not to lose sight of the terminal is that! Solder the red wire in the middle connector (in position 9) of the AC outlet. This allows the AC adapter ...



Battery 7.Reconnect

This AC includes a normally closed switch in the shell (ground), so you can power the device as built with batteries, but when you connect the adapter the batteries are disconnected (and not shorted to ground or polarization negative side).
