Hello Dan 1) Electronic is also my week point, sorry I don't know what should be the resistor value. 1b) NO, 10 V is to supply the mega/due. In this post http://ardumower.de/index.php/de/forum/ardumower-platinen/765-bei-dc-wandler-vin-nur-noch-2-7-volt#7994 I provide a hand written schematic...

Hi 1) These resistors (and the Zener diodes that go together) are optional and are not part of the standard delivery. 2) U10 is the place for a level shifter (converting 5V 3,3 V), when using DUE. But even in that case it is not always necessary because the 2 devices (IMU and RTC) that use the...

Hi Stephan Yes I use 2 blades, you can see the detail here: http://ardumower.de/index.php/de/forum/dies-und-das/716-was-wiegen-eure-roboter#7591 The idea is to cut along the perimeter (300 m in my garden), but the risk linked to blades must be minimized. It is a common good practice to...

Following is an example on how to mount on the mower motor small encoders bougth in the shop: https://www.marotronics.de/Magnetic-Encoder-Pair-Kit-for-Micro-Metal-Gearmotors-12-CPR-27-18V This allows speed regulation for a better cut, otherwise the speed may vary, depending on grass thickness...

Hello I'd like to share some improvements I wrote in the sender software, based on version 592 : - menu on console with many options; - easy change of language for menu and logging, done in a single file; - drive the 2 wires which are already available in the hardware; - automatic reduced...

Hello Pierre Definitively better with a computer and a large screen :) I think i find something very similar to yours (inside) and in english : http://ardumower.de/index.php/de/forum/your-projects/402-tianchen-tc-g158-conversion If that's rigth, then search for Tianchen mower, there are lots...

Hello I'm trying to get the sender with differential signal (Version 2) and the pwm capability, using the potentiometer, working together. But it doesn't :( From my understanding (I'm not an expert, it's my 1st arduino project), it cannot understand how it could work because : + the diff...

Hello I have finished my sender, installed the perimeter wire (297 m length, 1 mm² from the shop, ~7.2 Ohm, .96 A under 7.3 V), and wanted to test it before increasing the power, but I cannot get the web oscilloscope to start. :( I first tried under XP SP3, firefox (version 28), the scope...

Hello I think I 've found a mistake in the gps.cpp software v1.04A. See below, I commented the original line where the longitude is equalled to lat(itude). Shouldn't it be lon(gitude) there as I replace in the following one? Greets void GPS::f_get_position(float *latitude, float *longitude...

Hello I'm also building a mower with a 25.6V 6.3 Ah LiFePO4 pack, assembled by myself, with an onboard Battery Management System (http://www.eclipsebikes.com/lifepo4-288v-cell-30a60a-p-1040.html) and a matching external charger ( http://www.eclipsebikes.com/lifepo4-battery-charger-p-1036.html)...
