Its weight is also very low with batteries contributing most of it. We are working further to simplify the circuit more so that assembling the circuit becomes a layman's job.fablabhttp://www.blogger.com/profile/15727041036617205631noreply@blogger.com0tag:blogger.com,1999:blog-35531427.post-1034464842533593122007-01-11T20:38:00.000-08:002007-01-11T20:46:45.204-08:00LOW COST HEARING AID<br /><br />It is a unique project by FABLAB.IT has a simple circuitry that can be assembled by any one .<br />The cost of whole product can be less than a dollar and so it comes with great affordability to all the poor patients who dont have access to costly machines that can enhance there hearing ability.fablabhttp://www.blogger.com/profile/15727041036617205631noreply@blogger.com0tag:blogger.com,1999:blog-35531427.post-86689622718985397162006-12-22T03:39:00.000-08:002006-12-22T04:08:22.849-08:00<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgj3g7BtkXNwZ0QZGTn2LM6zxwxuPx4wltUdd82Pp595zPTjXMOVe4brfutXfiZpad6_G0fBCrXzEJNsjgs1a1KTdZSg5UnCdn-uwevINJKS6-FX4g00KuB7uTzeXFPuN_qtZNMHQ/s1600-h/100_3112.jpg"><img id="BLOGGER_PHOTO_ID_5011315054709738274" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgj3g7BtkXNwZ0QZGTn2LM6zxwxuPx4wltUdd82Pp595zPTjXMOVe4brfutXfiZpad6_G0fBCrXzEJNsjgs1a1KTdZSg5UnCdn-uwevINJKS6-FX4g00KuB7uTzeXFPuN_qtZNMHQ/s320/100_3112.jpg" border="0" /></a> <span style="color:#3366ff;"><strong><em>Wind mill model using metal acrylic.
