<html><body> <DIV>I see there has been alot of talk on this subject and I haven't read all the posts so please forgive me if I repeat any previous posts. I have an HP IPAC with Cyber Tuner on it. I bought it as a rebuilt unit from Rayburn. I don't think it has any special battery and I have never had a problem with it not staying charged for the tunings I need. I tune on an average of an hour and close to an hour and a half on a pitch raise which is what I use the Cybertuner for mostly. I do tunings in a school and have been able to tune 6 pianos on one charge. That is a rarity though,usually of the 5 tunings I will do in a day I use the Cyber-Tuner for 3 or 4 depending on my fatigue level and the type of piano and customer. I keep the Cybertuner in the charger everynight when I come home and have no problems. I have been using the same unit now for almost 4 years on the same battery. Probably now I have jinxed myself and I will have to by a new battery. Or just rely entirely on my aural s kills.               Robin Olson</DIV> <DIV>                                                                                                                              </DIV> <DIV> -------------- Original message -------------- <BR>From: "Farrell" <mfarrel2@tampabay.rr.com> <BR></DIV> <META content="MSHTML 6.00.2900.3314" name=GENERATOR> <STYLE></STYLE> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV><FONT face=Arial>I did two tunings today on Yamy C3 - both needed a real serious tuning. I spent about 1.3 hours on each piano and ran the Verituner program on my HP ipaq 111 for the full duration. My ipaq has a 1.2 Ah battery. I had 77% battery capacity left after the first tuning and 55% left after the second tuning.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>I'm part of the "good tools cost some $$, but usually pay for themselves in the long run" crowd. I ordered my Spurlock PDA cradle the same day I ordered my PDA. I knew I would need it and I knew Bill's jig would be a workhorse. I've tuned several pianos with it now and it seems to work like a charm. I also bought his little grand plate strut clamp for mounting the PDA cradle - it is very handy and works well.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Terry Farrell</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=atuneforyou@gmail.com href="mailto:atuneforyou@gmail.com">Steve Blasyak</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Monday, May 05, 2008 11:26 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> PDA's/ Batteries</DIV> <DIV><BR></DIV> <DIV>Hey  Now,</DIV> <DIV> </DIV> <DIV>Not for the sake of argument, but for clarification. I don't think the Verituner uses any more battery power than any of the other programs. That statement is based on my own personal experience. I have used all three programs with my current PDA (Ipaq 2795b), and I don't notice any significant difference.</DIV> <DIV> </DIV> <DIV>Marcel apparently your Ipaq 2410 must have a superior battery, or perhaps you get five or six tunings per charge because you can tune a piano in a half an hour, I don't know. All I can say is my experience is more in line with what Terry originally described at the beginning or this thread. As I've said before I have a friend with a Dell Axiom that will run Cybertuner all day, so it certainly seems possible all PDA batteries are not created equal. The car charger option is the cheapest and has always worked for me.</DIV> <DIV> </DIV> <DIV>Terry, as far as Gregor's super thick battery add-on, with your creativity I'm surprised you don't just make a stand out of scrap wood. When I originally switched to the PDA format I liked the Spurlock PDA stand but baulked at the price (I know I'm cheap), so I just made a little wooden stand. </DIV> <DIV> </DIV> <DIV>Steve Blasyak</DIV> <DIV>Orange County Chapter</DIV> <DIV> </DIV> <DIV>Pura Vida</DIV></BLOCKQUOTE></BLOCKQUOTE></body></html>
