  • NSLU2 for TF5800PVR Access Over Ethernet
    Configure NSLU2 for TF5800PVR access over Ethernet Summary A Linksys NSLU2 is a paperback size unit that has Ethernet and USB ports. Using this the Topfield TF5800 PVR can be accessed over a home network. The NSLU2 is about £55 but needs custom firmware to access the Topfield. This document describes the installation process on a Windows PC. This configuration does not use any USB drives on the NSLU2. Make sure you read the appendix for latest info. Author Malcolm Reeves ([email protected]) Issue: Draft H Date: 6-May-06 Contents 1. Initial Test 2 2. RedBoot 3 3. Install Unslung 4 4. Install ftpd-topfield 5 5. Upgrades and Configuration 7 5.1 Turbo Mode 8 Appendix A - Rafe’s Comments 9 1. Initial Test So you’ve bought a NSLU2. Let’s test it and make sure it’s working. So connect it your home network. Most home networks are 192.168.0.xxx (where xxx is any number between 1 and 254) with a mask of 255.255.255.0. This range is reserved for local networks and it’s what Windows defaults to. You’ll need to change the mask to 255.255.254.0 on your PC and on your router if you have one. This is because the default IP address of the NSLU2 is 192.168.1.77 which is not on the default local network. After changing the mask enter 192.168.1.77 in a browser URL bar. This should bring up the Linksys web setup pages for the NSLU2.

    NSLU2-Linux | HowTo / OverClockTheSlug http://www.nslu2-linux.org/wiki/HowTo/OverClockTheSlug?action=print From NSLU2-Linux HowTo: OverClockTheSlug There appear to be two models around -- please verify that you are running at 133 before doing anything else ''' Tired of sluggish performance? Want to squeeze a bit more out of your slug? Feel that you're not getting the dish you paid for? Overclocking (De-underclocking) the Linksys NSLU2! (or how to get your own TurboSlug) Notes on Slugs supplied at 266Mhz: Edit: My brand new Slug comes from factory with BogoMIPS : 263.78, so it is already running at 266 MHz ?. The Slug is marked with a sticker: Manufactured 05/2006. Maybe someone from Linksys has read this page :) Edit: Mine also comes from factory running at 266Mhz ;) - Manufactured 05/2006 Edit by Bullfrog: Mine also comes from factory running at 266Mhz ;) - Manufactured 05/2006 - R64 is also now no longer fitted next to flash chip near serial port which with R83 fitted and R81 missing - gives the undocumented code for 266Mhz Edit by Charly: Mine also comes from factory running at 266Mhz ;) - Manufactured 05/2006. Also the French power adapter is twice smaller for same power (5V 2.0A) Edit by halfer: purchased 10/May/2007 and found that the " XScale ??-IXP425/IXC1100 " is already running at 263.78 BogoMIPS Notes on Slugs supplied at the standard half speed: Edit by Steve 2/25/2007: Purchased yesterday. Mine came with V2.3R73. Only a windows guy so couldn't verify speed. Task manager showed 31% network usage on large files (>2 GBytes ?).

Proprietary software in a non-default area. [3] Official website www.debian.org Debian (/ˈdɛbiən/) is an operating system composed of free software mostly carrying the GNU General Public License, and developed by an Internet collaboration of volunteers aligned with the Debian Project. It is one of the most popular Linux distributions for personal computers and network servers, and has been used as a base for other Linux distributions. Debian 2 Debian was announced in 1993 by Ian Murdock, and the first stable release was made in 1996. The development is carried out by a team of volunteers guided by a project leader and three foundational documents. New distributions are updated continually and the next candidate is released after a time-based freeze. As one of the earliest distributions in Linux's history, Debian was envisioned to be developed openly in the spirit of Linux and GNU. This vision drew the attention and support of the Free Software Foundation, who sponsored the project for the first part of its life.

  • How-To Build Meteohub on Sheevaplug (The Easy Way)
    How-To Build Meteohub on SheevaPlug (the easy way) The SheevaPlug is a low power, small form factor device that can be seen as the successor of the famous NSLU2. Meteohub has now been experimentally ported to the SheevaPlug. Please be aware that this port is rather alpha, but it seems to work. At the moment Meteohub on SheevaPlug has these limitations: ● no WebCam support: This is also not planned for the future ● no WLAN support: Might be added via USB WLAN sticks in the future (low priority) ● no Labjack support: unclear if this can be added by a home-brew kernel module, low priority Meteohub on SheevaPlug makes use of a SD card where operating system, Meteohub application and data are stored. Capacity is 4GB. It should be a SLC based card. As not all SD cards are working with the plug, you might have some experiments in front of you. SLC-based SD card that is proven to be working ● Transcend SDHC Class 6 150x: TS4GSDHC150 Weather stations are connected to the Meteohub by USB connector. This one USB port can be extended with an USB hub. It looks like it can be a passive USB hub, as the Meteohub provides the 500mA on USB and this should be enough to drive a few weather station USB connections and/or RS232-USB converter. Meteohub on SheevaPlug consumes about 5 watts , which is really effective. Meteohub's performance looks fine. It can do about 900 records per second during recomputation (NSLU2 is about 200, x86 Geode platforms are up to 2000).

  • Low-Cost Conversion of Single-Zone HVAC Systems to Multi-Zone Control Systems Using Low-Power Wireless Sensor Networks
    sensors Article Low-Cost Conversion of Single-Zone HVAC Systems to Multi-Zone Control Systems Using Low-Power Wireless Sensor Networks Julio Antonio Jornet-Monteverde 1 and Juan José Galiana-Merino 1,2,* 1 Department of Physics, Systems Engineering and Signal Theory, University of Alicante, Crta. San Vicente del Raspeig, s/n, 03080 Alicante, Spain; [email protected] 2 University Institute of Physics Applied to Sciences and Technologies, University of Alicante, Crta. San Vicente del Raspeig, s/n, 03080 Alicante, Spain * Correspondence: juanjo@dfists.ua.es; Tel.: +34-965-909-636 Received: 31 May 2020; Accepted: 25 June 2020; Published: 27 June 2020 Abstract: This paper presents a novel approach to convert a conventional house air conditioning installation into a more efficient system that individually controls the temperature of each zone of the house through Wi-Fi technology. Each zone regulates the air flow depending on the detected temperature, providing energy savings and increasing the machine performance. Therefore, the first step was to examine the communication bus of the air conditioner and obtain the different signal codes. Thus, an alternative Controller module has been designed and developed to control and manage the requests on the communication bus (Bus–Wi-Fi gateway). A specific circuit has been designed to adapt the signal of the serial port of the Controller with the communication bus. For the acquisition of the temperature and humidity data in each zone, a Node module has been developed, which communicates with the Controller through the Wi-Fi interface using the Message Queuing Telemetry Transport (MQTT) protocol with Secure Sockets Layer / Transport Layer Security (SSL/TLS) certificates.
