Hi, Motorola makes a 40g acceleration sensor (senseon is the name). so, depending on the precision you require, you could go up to there. For the storing of data, it is pretty simple, so is the interface. As for consultation services, it is out of my league but help can usually be found here. +--------------------------+-----------------------+ | | ABL Canada inc. | | Jacques Audette | 8550 Cote-de-Liesse | | Hardware design | St-Laurent, Qc | | Video Codecs | H4T 1H2 | | | Tel: (514)344-5432 | | jacques.audette@abl.ca | Fax: (514)344-5439 | +--------------------------+-----------------------+ > ---------- > From: Subhi Eldeiry[SMTP:seldeiry@POL.NET] > Reply To: pic microcontroller discussion list > Sent: Tuesday, March 31, 1998 3:22 PM > To: PICLIST@MITVMA.MIT.EDU > Subject: Physician inventor > > I need information that helps me evaluate the feasibility of inventing a > very simple and very small, but strong electronic device(to start with), > that has the capability of sensing and recording in memory, and > retrieving: impacts.
