This was what Larry Barello specified. > SH1 and SH2 are just little plated through holes on the WW-02 board. It looks like the servo cables used to connect the motors in the level one kit are to big in diameter. Hmm, I'm not sure about that. I was not involved in the design of the SRS kit, just this encoder. I personally would go ahead and strip off a little insulation on the existing motor wires and see if they will fit. I find it easier to insert a stranded wire in a hole on a PCB if I tin the wire first with a little solder. > Could I use some excess 22/24 AWG from the sensors for this or would this wire be to light. > This would probably not be too light, since those motors do not draw a lot of current, and the length of the wire would be fairly short anyway. > Also, the WW-02 manual mentions adding decoupling caps.

It looks like the Level 1 kit has such a capacitor, Digikey part number P4924-ND. Radio Shack has a similar part, #272-135. The value is not that important, though -- anything from .01uF to .1uF should work fine. Solder one between the motor terminals, plus one from each motor terminal to the motor's case. This effectively eliminates the electrical noise from the motor's brushes. -Pete From jronald@chartermi.net Sun Sep 17 20:04:38 2006 Return-Path: Delivered-To: mailman-wheelwatcher@list.nubotics.com Received: (qmail 3685 invoked from network); 17 Sep 2006 20:04:38 -0000 Received: by simscan 1.2.0 ppid: 3664, pid: 3670, t: 2.7214s scanners: attach: 1.2.0 clamav: 0.88.3/m:39/d:1587 spam: 3.1.3 X-Spam-Checker-Version: SpamAssassin 3.1.3 (2006-06-01) on tencom.noeticdesign.com X-Spam-Level: X-Spam-Status: No, score=-1.8 required=5.0 tests=BAYES_00,HTML_30_40, HTML_MESSAGE autolearn=no version=3.1.3 Received: from mxsf17.cluster1.charter.net (209.225.28.217) by 69-30-73-98.dq1mn.easystreet.com with SMTP; 17 Sep 2006 20:04:36 -0000 Received: from mxip06a.cluster1.charter.net (mxip06a.cluster1.charter.net [209.225.28.136]) by mxsf17.cluster1.charter.net (8.12.11.20060308/8.12.11) with ESMTP id k8HK4XPN023167 for ; Sun, 17 Sep 2006 16:04:33 -0400 Received: from 24-247-92-225.dhcp.bycy.mi.charter.com (HELO jr7cce2911b481) ([24.247.92.225]) by mxip06a.cluster1.charter.net with SMTP; 17 Sep 2006 16:04:33 -0400 X-IronPort-AV: i="4.09,177,1157342400"; d="scan'208,217"; a="728073688:sNHT1020530196" Message-ID: <004f01c6da94$738fd9a0$6501a8c0@jr7cce2911b481> From: "James Ronald" To: "WW-01/WW-02 WheelWatcher Encoder Support List" , "Pete Skeggs" References: <003d01c6d9da$90c02fd0$6501a8c0@jr7cce2911b481> <450D7E52.9010607@noeticdesign.com> Subject: Re: [WheelWatcher] WW - 02 & SRS Workshop Robot (ARC 1.1 uC Board) Date: Sun, 17 Sep 2006 16:04:08 -0400 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_004A_01C6DA72.E848A640" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2900.2869 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2869 X-Content-Filtered-By: Mailman/MimeDel 2.1.3-b-pls Cc: X-BeenThere: wheelwatcher@list.nubotics.com X-Mailman-Version: 2.1.3-b-pls Precedence: list Reply-To: WW-01/WW-02 WheelWatcher Encoder Support List List-Id: WW-01/WW-02 WheelWatcher Encoder Support List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 17 Sep 2006 20:04:39 -0000 This is a multi-part message in MIME format. ------=_NextPart_000_004A_01C6DA72.E848A640 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Pete, Thanks for the reply.
