TI’s MSP430 has attracted a lot of microcontrollers enthusiasts (that includes me) not just because its crazily cheap $4.30 but it also has the basic features that you would need to get your project going. Not to mention the Code Composer Studio that is used to program the microcontroller is also competitive.
VistaQuest VQ1005 – an old fashioned digital camera that was opened (by the owner not me no no no) up a couple of years ago. The first approach was to use the 555 timer integrated circuit to trigger the camera at timed intervals and when you get the photos together you’ll end up having a time lapsed photo – neat huh, simple but it could do the job. The only problem was that there is a time interval restriction since the VistaQuest VQ1005 will go to sleep mode when there is no activity for a certain period of time.
How did he go through the modification? Its actually quite simple. A tap was made on the the camera trigger (the one that you click to take a picture) when this line is driven low (0 Volts) then a picture will be taken. Another tap was made on the cameras On/Off switch this line would ensure that the camera is powered up when its time to take pictures – this would also get by the sleep mode problem and will help is saving power.
