| 624557 | 2007-12-25 21:40:00 | One of my kids got a toy that uses 3x C-size batteries for Christmas, and I imagine it will suck them dry fairly quick. Is it possible to somehow attach a transformer to the toy and plug it into the wall? If so how, and where do I go to get it? Mike. |

| 624558 | 2007-12-25 21:45:00 | Well has it got the adapter for a transformer?? If it has, it should say the voltage and whether its need a positive or negative centre. |

| 624559 | 2007-12-25 21:48:00 | No it only takes the 3x C-size batteries - nowhere to plug in a transformer. That's what I'm asking - is it possible to somehow attach a transformer to where the batteries would go (or similar) so I can run it from that? Mike. |

| 624560 | 2007-12-25 22:16:00 | If you are handy with a soldering iron try the following: I am assuming the batteries fit in one row ie in series. Obtain a 4.5v power plug pack (DSE have Cat M9646 or 9647) Also some fine insulated cable (2 core) and a suitable socket try either P1653 1650 or 1661 also from DSE Open up the battery compartment remove batteries and solder one end of each core of the wire wire to the each of the battery spring clips with the other end to the socket fittings. Then set the power adapter to 4.5v and fit the plug to the socket. This will then provide the power to the device. To pre test use small spring clips to hook up before soldering. |

| 624562 | 2007-12-25 23:04:00 | It may - the batteries may be still in series & using 4.5v or it may have a 1.5 and a 3v supply not seeing it I cant really advise anything but to experiment and use the temporary clip method - one end to the -ve of the 2 battery pair and the other at the +ve end of the single one - what is the device? | GrahamT (291) | ||
| 624563 | 2007-12-25 23:50:00 | what is the device?its a musical keyboard thing. Mike. |

| 624564 | 2007-12-25 23:58:00 | Also worth considering may be the use of re-chargeable batteries instead of a plug pack. It keeps the portability and no wires for others to trip over. Just a thought. | pheonix (36) | ||

| 624566 | 2007-12-26 04:25:00 | Ya gotta make sure that any power pack you make also has clean enough current for the device . Batteries have no waveform in their supply . . so be careful to make sure the power supply is clean and has no sine wave or any other wave form in the current . As far as not using any rechargeable batteries, I don't follow the logic . . but it might be that rechargeables aren't as "hot" as regular batteries or that the voltage is very important . . and many rechargeables don't have the power of a good set of D-cells . Amperage may be very important to the device . I don't get any other implication . |
