Has Your Pulse Album L.E.D. Stopped Flashing?

A novel feature of Pink Floyd's album - PULSE (EMI - European Version) is a red flashing L.E.D. (light emitting diode) situated on the front edge (spine) of the disc box. Even if you don't own the album you must at least have noticed it in your local record store, looking very eye catching in the rack with it's little beacon flashing away and even more eye catching if there is a number of then, all, flashing seemingly at random.

In the past months I have noticed in a few stores that with some copies of the album, the L.E.D has stopped flashing - the batteries have run down!

Soon after I received my Pulse album (as a birthday present) I just had to have a look inside at the gubbins that makes the L.E.D. flash. After careful surgery a small P.C.B. (printed circuit board) was revealed. Surprisingly, a very high quality P.C.B. The board, not only having being made to a very high standard, contained a Industrial Alkaline battery as it's power source. The Floyd spared no expense with the design and construction of this small but very welcome addition to their album.

Disclaimer - Please Read.

Before you start to operate on your dead Pulse album L.E.D. please be aware that I accept no responsibility what-so-ever if you spoil/damage the box, the P.C.B. or even the discs or booklet which make up the Pulse album. Please read these instructions carefully and be sure that you are able to follow them and can complete the procedure successfully before you embark upon the task.

Tools required:

I tried a number of different tools to get at the circuit board, but settled on just two tools/utensils that every body owns:

  • A dinning knife and a dinning fork!

The knife really needs to have a dull edge as the most risky part of the operation is trying your best not to cut through the box covering, and spoiling the appearance of the album box.

Let's Get Started.

Remove the booklet and the card insert from the Pulse box. Holding the empty box, as below, gently insert the knife blade.

Knife enters Pulse sleeve!

Slightly flexing the box to allow better access very gently cut the joint between the card insert/partition from top to bottom and the wall of the box gradually sliding the knife further into the box. Be very careful, if you slide the knife in too far you will cut through the spine and spoil the box!

The 1st cut is the hardest!

Once you have released the partition use a fork to leaver it outwards. The partition can not be removed completely as it is part of the box construction and is permanently attached!

Careful now!

Once the cardboard partition has been gently levered back the circuit board will be revealed. The board is attached to the partition by small piece of double-sided sticky tape and will probably move away from the front of the box as the patron is levered back. Carefully prize the circuit away from the partition by inserting the knife between the tape and the cardboard and not between the tape and the circuit!

Wow! The circuit board.

Using the fork, carefully remove the circuit board (try not to short and of the circuit connections) and examine its neat construction.

What a tiny thing!

The battery is located, as illustrated, in a holder. Remove the battery, noting it's orientation, and fit a replacement making sure it is inserted the correct way around. You should immediately see the L.E.D start to flash, if not, then recheck the orientation of the battery, if the L.E.D. still refuses to flash check this page out  the Pulse Manufacturing Errors! The battery should, preferably, be an alkaline type although the type of battery is not too important, and an ordinary inexpensive replacement cell can be used, as once the box has been initially operated on it is very easy to change the battery on the next, necessary, occasion.

New battery being inserted.

Once the L.E.D. is flashing again and you have finished your examination of the circuit then slide the circuit back into the box carefully locating the L.E.D. using the knife, be careful not to short and of the circuit connections, with slight pressure on the white sticky double-sided tape only, into it's recess on the spine of the box.

Re-insert the PCB.

Next relocate the cardboard partition, again, using the knife, you should find that the lip of the partition will locate and slide back towards the spine of the box with ease.

Is it secure?

The procedure is now complete. Replacing the booklet and the card insert back into the box and standing the completed album set back in your CD rack, you should again be able to marvel at the uniqueness of this totally outstanding album.

Blinking marvellous ;-}
