Scary Halloween Kit

Just thought some of my experiences might be interesting to read by other potential kit purchasers etc,

My experiences so far with the Scary Halloween Kit are,

Initial build - Solder blob was required on the Sound Module for 3.3V working(no factory default fitted)
- Sloppy K2/K3 socket connector strip for the sound module(fixed by inserting wire-wrap turn-pin socket strip suitable for sound module pins)
- Fitted my own power input terminal connector K1 for multistrand wire battery connection.
- Excessive solder on sound module pins almost short circuit with SD card holder's sliding metal cover.

Failures to date - The Kingstate KDMG20008 loudspeaker(0.3W) went open-circuit after about 6-hours operation, replaced with a one of high power rating that I had to hand(8ohm/12W).

Other comments - power-up procedure not the best experience, but still love the kit all the same, very gimmicky for Halloween and easily adapted for other occasions.

Ik heb twee kits gekocht. Beide hadden het door Ray gesignaleerde probleem dat het metalen dekseltje van de card-houder kortsluiting maakt met de gesoldeerde pinnen op de soundmodule, waardoor die niet werkte. Kon dat alleen verhelpen door het dekseltje te verwijderen en het kaartje met een externe klem vast te zetten. Maar dat lijkt natuurlijk nergens op. Verder ook eens met Ray dat de K2/K3 connectors allesbehalve stabiel zijn. Ook daarvoor had wel wat beters meegeleverd mogen worden.

I fixed the potential short circuit pins on the SD card holder by removing some of the excess solder using solder braid and iron.

Elektor Labs advises:

"Delighted to see you have the project working. In the next batch (current batch almost sold out) we will put better speakers and a better connector for the sound module. The MP3 sound module remains a problem. We asked the company if there are 100 pcs left over from the old stock, we’ll know soon. We tried some MP3 modules and they had no short circuit."

Here is a short manual from Elektor Labs about mounting the sound module on pinheaders for better contact: ... lepins.pdf

Guten Tag,
beim Aufbau habe ich gesehen das statt 4*10k nur 1*10k beigelegt ist.
Und statt 1*10 Ohm fand ich 4*10 Ohm!

Auf dem Voice-Modul muß auch noch die Brücke gelötet werden für 3,3V.
Das ist nicht in der Beschreibung dokumentiert.

Der Lautsprecher hat die Leistung von 0,5 W. Vorgeschlagen war doch aber 1,5W.

Der Bewegungs-Sensor reagiert, aber der Lautsprecher gibt nur ein zischen von sich!

Hello, at last I found some time to put this kit together. I realised that there were wrong amounts of resistors, and I put a soldering blop for 3.3V on the sound module.

Unfortunately the module is not working. Setting the jumper JP2 to the right position enters the scan mode. The module finds only one sample file, but the sound is only a hiss. After that the LED are blinking continuously. When I put JP2 to the left position, the circuit is working: when the PIR detects something, the LEDs are blinking, but the loudspeaker reproduces only that hiss that can be heard in the scan mode.

Of course I put the 21 *.ad4 files to the SD card.

Any advice? Unfortunately the link mentioned above (short manual from Elektor Labs about mounting the sound module on pinheaders for better contact) is not working any more.

Best regards, Kosmas
