New Trezor Native Ethereum Wallet Beta Guide / Features

Trezor Ethereum Wallet Beta Main Page

The support on Trezor was traditionally just a link to a third party service where you had to log in through the web interface and export your keys every single time. You can’t even see your balance until you do this!

Fortunately true native Ethereum support has arrived for Trezor in the beta! Not only that, but ERC20 token support was also added which has made Trezor now an extremely capable Ethereum hardware wallet. The beta wallet supports all Trezor wallet devices including Trezor One.

In this article we will examine these new features in depth and give a final verdict!

Wireless Alternative Using Ethernet Over Power – Black Magic?

Ethernet Over Power Wall Rack

Ethernet over powerline tech has existed for a while but traditionally has frankly sucked. It was slow and had issues with reliability.

After decades of improving standards and technology this has changed dramatically and now makes a very cheap and attractive alternative to wireless in many situations. The latest iteration gives a 1200 Mbps connection right over your existing power lines in your house and is designed to work in “noisy” power environments without interruption.

Raspberry Pi 4 USB Boot Config Guide for SSD / Flash Drives

Raspberry Pi 4 with Samsung 950 Pro NVME SSD

The Raspberry Pi 4 is finally here and has a lot of exciting changes. One very major downside is that it doesn’t support true USB booting yet out of the box (like the 3 series did).
The Raspberry Pi foundation states that it is being worked on and will be added back with a future update. No timeline has been given yet for that to happen but they state it’s one of their top priorities.

Most of my projects heavily depend on having good performing storage so sitting and waiting was not an acceptable solution. In this guide I’ll show you a workaround to use USB devices as your rootfs device and use a Micro SD card as bootloader only which gives us full SSD performance after boot!

Early Bitcoin ASIC Miner Pictures / History / Analysis / Prices

Block Erupter ASIC setup

The most competitive Bitcoin mining operations today consist of entire warehouses of large ASIC miners usually located near sources of renewable energy or power plants selling off excess energy production for cheap. To get seriously involved in the Bitcoin mining space of today will require you to already be quite wealthy and to put up some *serious* cash.

But things were not always this way. I found a bunch of pictures in my photo library of my old mining rigs back from the dawn of Bitcoin ASIC mining and wanted to share them. Let’s go on a journey together back to the year of 2013 and explore what old school Bitcoin mining ASIC hardware looked like, how much it cost, and what we can learn from them today!

Raspberry Pi Storage Benchmarks 2019 + Benchmarking Script

Pi Benchmark 2019 Contenders

Storage options continue to advance at a very fast pace. We’ve seen a lot of changes in the past couple of years with viable storage options for your Pi. Solid state drives are now so cheap that it can be cheaper to outfit your Pi with a SSD than buy a MicroSD card! MicroSD cards also continue to evolve with the new “Application Class” A1 and A2 certifications.

This year I wanted to do something more than just benchmark my ever-growing pile of MicroSD cards and solid state drives. Although I have a wide variety of storage to test I don’t have everything! So this time I created a benchmark that gives you a easy to compare score and anonymously submits the storage specifications and the results to this site.

Running the benchmark is a one-liner:
curl https://raw.githubusercontent.com/TheRemote/PiBenchmarks/master/Storage.sh | sudo bash

Turn Old mSATA SSDs To Fast USB 3.0 Flash Drives

Since the M.2 NVME form factor has won the high performance solid state drive war many of you may be stuck with older micro SATA (mSATA) drives.  These still have a very awesome use that will only cost you $10 to take advantage and have a blistering USB stick instead of throw them away!

These are full blown SSDs and their performance blows a regular USB flash drive out of the water.  They support the trim command and show up as “fixed disks” instead or removable storage.  This means they support cache write optimizations that normal USB removable drives don’t.  This allows you to do all sorts of awesome things on them.  Some examples:  Windows to Go, Fast Portable Linux, Virtual Machine storage, etc.  You can also just use it as a really fast drive to transfer files back and forth with your friends while looking like a total techie badass.

Old Skool NES Classic Case Fan Mod

Pi Classic Fan Case Open

This is a followup to my awesome Old Skool NES Classic RetroPie build.  When I posted my build on Reddit several users that already had the case noted that the case tends to get very hot.

That’s not good, but since the case is so awesome I was determined to find a solution.  This mod requires no soldering, no drilling, and is dead simple and cheap.  It also does not modify the look of your NES Classic RetroPie setup at all!
