All you need is a fortyone beep - Hans-Peter - 05-01-2016 06:44 PM
My real missing function on a WP34s is the beep, when a program is finished. I use the IR way to give the signal, "hey the work is done". Here is the video:

You need:
IR Receiver Infrared Radiation Module 38 kHz Remote TSOP4838 DIP-3
Voice ISD1820 Recording Recorder Module With Mic Sound Audio+Loudspeaker (or a better one from an old PC)
a 2 AAA Battery holder box (3V) and a universal case
a switch and an old cable of an earphone 3.5mm
With some modifications, you have a nice tool for an acustic signal.
It also works with any tv remote control. For activation from a WP34s with IR option, you can use any short printer command.
My next project is a IR controlled power switch for AC usage. Then I can switch my pc with my WP or my HP41 (with IR module) on. :-)
Best regards
