List of Issues and possible fixes

[ledbfg]

When I get time in the next week or so I'm going to do a complete redesign of the case and the circuitry. I've made 5 of these and have found the design to be rather poor I'm afraid. Here is a list of all the issues I have encountered so far. I'm sure I'll be able to add more soon.

Issue 1 - Hand is only detected when it is right in front of your upper rib cage / neck depending on length of necklace, which rarely happens when you causally touch your face as you typically don't lift your hand from the center of your rib cage straight up. You just reach either hand up to your face, approaching from the side - If you're lucky it will vibrate for a fraction of a second as your hand passes over it. The photos and video promoting this item are misleading, showing that your hands can be detected when they are straight up at either side of your face. This is certainly not the case. It only works when your hand is in the center of your body, below your chin. Fix - Have two sensors (not in the center of your body, but placed 160mm apart with a complete new style - not a small pendant but a long curved pendant) to detect both hands. I've tested this by just holding the current design to either side, and it will detect your arm the whole time you touch your face.

Issue 2 - Can't feel the vibrations if standing - pendant needs to be resting on you (when sitting or lying) to make contact with your body to feel the very faint vibrations. Fix - have an option for a buzzer - the vibrating motor or buzzer can be selected with the same style of slide switch already used - or have 3 switches, one for on/off, one for vibrate on/off and one for buzzer on/off.

Issue 3 - To change the battery, you have to open the whole case, exposing all the fragile circuitry. This is no good for someone who isn't used to handling small fragile items. It can easily be broken in many ways as one of my friends has already broken theirs, the black IR sensor snapped clean off of the top of the circuit board when changing the battery. Also, the guide says the the sensor "snaps in place" - again this is not the case, it barely holds it in an upright posistion, I have resorted to using hot glue to fix all the components in place, and with a clear, or white case, the sensor needs to be sticking out a long way to avoid false triggering by the case. - if it is in place like the photos show, even with the underside painted black, it vibrates constantly without stopping. Fix - My new design will have a dedicated opening for just changing the battery (batteries? I may include 2 batteries) and will have secure holders for the sensors.

Issue 4 - sensor needs to be sticking out really far to stop false triggering Fix - Print in BLACK plastic, the need to paint the underside of the sensor is not a good fix for this issue.
