I am working on computers again and wanted to share the fixing and upgrading of this Toshiba Satellite L455D. It came with Windows 7 (32-bit) and part of the upgrade involved removing viruses, fixing the registry, defragging the drive, BIOS update and removing lots of bloatware. Last but certainly not least the RAM was doubled from 2GB to 4GB and replaced an ancient hard drive (5400rpm) with a solid state drive. 🙂
It was so bad it took around 5 minutes to simply boot up into the desktop. Plus, when I tried doing a re-assessment of the Windows Experience Index score it failed to complete! Afterwards, as you can see in the video it boots up a lot faster!
We’ve all of course know about the Internet but recently there has been the development of Outernet. It’s been dubbed as the ‘library in the sky’ as it is meant to freely provide vital information in areas of the world where internet is scarce or non-existent. This will benefit people living in an areas hit by a major natural disaster, war-torn countries or trying circumvent censorship.
This is an excellent guide from rtl-sdr.com on all the hardware and software needed in gaining access to the Outernet. The cost is relatively inexpensive for about less than $100 and there are also guides on how to build your own patch antenna if you chose not to buy one. You also don’t necessarily have to use a Raspberry Pi3, you can run it on a Windows/Linux system though support is limited (at the time of this writing).
I shall put a link to the original article at the bottom and the tutorial begins immediately down below.
RTL-SDR TUTORIAL: RECEIVING AND DECODING DATA FROM THE OUTERNET
Outernet is a relatively new satellite service which aims to be a “library in the sky”. Essentially their service is going to be constantly transmitting files and data like news and weather updates from geostationary satellites that cover almost the entire world. Geostationary means that the satellites are in a fixed position in the sky, and do not move over time. By simply pointing a small patch antenna at the sky (with LNA and RTL-SDR receiver), it is possible to download and decode this data from almost anywhere in the world. Their aim is to provide up to date information to users in locations with little to no internet (rural, third world and sea), or in countries with censored internet. It may also be of interest to disaster preppers who want an “off-grid” source of news and weather updates. It can kind of be thought as a kind of one-way download-only internet service.
Every time we talk on Skype (which isn’t much) it seems like the signal is lost within about 1-2 minutes. If we’re lucky you’ll have up to 5 minutes of talk time before we’re cut off. This has been going on for about 2 years and it seems to be getting worse. We had a discussion a while ago on exactly how to improve your internet. I don’t expect you to remember all what was said, so I’ll post the brief version of what we discussed in this blog.
These are several methods that I think could improve your internet tremendously and you really should explore these 3 options.
Option #1 – Get a WiFi range booster:
This is by far the quickest, cheapest and easiest method in attempting to improve your signal. Nowadays just about any electronics store has them for about $35 and you’ll find them even cheaper on eBay. If the extender doesn’t help much, then chances are there’s a bottleneck going on with your landlord’s internet. Since your WiFi connection is shared by about 40 tenants I have a bad feeling this method will only give you mixed results. Since this is the easiest method I suggest trying this one first.
