try to use a PhidgetBridge 4-Input: getVoltageRatio raise PhidgetException(result)

Hi, I'm trying to read the voltage ratio from a 1046_0B 'PhidgetBridge 4-Input' https://www.phidgets.com/?tier=3&catid=98&pcid=78&prodid=1027 in Python. The code example from https://www.phidgets.com/?tier=3&catid=98&pcid=78&prodid=1027 works fine. The voltage ratio is printe...

Re: High noise level when sampling load cells over USB PhidgetBridge on SBC4 over USB

UPDATE: I've identified the problem. It was indeed the power supply. After using a very accurate lab power supply (Korad KD3005D), I get a low noise level of ~0.05 N (SD) at 64x gain. The noise level when recording with the laptop is the same (0.048 N vs 0.046 N). Update II: With two 9V batteries in...

High noise level when sampling load cells over USB PhidgetBridge on SBC4 over USB

Hi I've been recording force profiles with four CZL635 micro load cells [1] and a USB PhidgetBridge 4-Input [2]. When I record the data on my Laptop (Lenovo Yoga 2017) using a python script, I get a very nice signal, with a noise level below 1N. see Plot 1: https://ibb.co/cn1XkJ However, plugging th...

Transfering Files to SBC via PuTTy (pspc) under Windows 10

UPDATE: If you already have PuTTy running, its easiest to install WinSCP https://winscp.net/download/WinSCP-5.13.2-Setup.exe it will automatically transfer your PuTTy settings (if saved) and is easy to use (GUI). I still don't know how to transfer data from my SBC command line (keyboard or putty) to...

Not able to login to web interface: Error(s) You have specified a bad username or password.

When I enter my SBCs IP address (http://192.168.0.15) in the browser (Chrome) I get to the login.

However, entering the same username (root) and password that I use to successfully connect to the SBC via PuTTy gives me an error message:
Error(s) You have specified a bad username or password.

reading/mounting your SBC SD Card unter Windows 10

The file format used by the SBC is ext2. Windows does not support this format out of the box. 1) Plug in your micro SD card from your SBC into your Windows PC, you will be asked about formatting the drive. DO NOT DO THIS!!!! It will erase all your data. 2) Install https://sourceforge.net/projects/ex...

Re: Installing wget and unzip

Is there any way to install the full Debian Package Repository without the web interface. The latter does not work for me.

Re: Use Phidget control panel without Bonjour???

Update: All you need is the ip Address of the SBC. You can find it with, e.g. the angry IP scanner when the SBC and your PC are connected to the same network. Old: I was able to connect to the SBC after many attempts. Not sure what made the difference. From there I could open the web interface and i...
