$20 USB Printer Server Amazon

Question:  Have you ever used a WiFi printer setup?  It may sound like nothing special, but trust me, once you try it you’ll wonder why you waited so long. Some printers have WiFi built into them already [Brother for only $109 >] and some printers need a wireless print server. This is where the D-Link wireless print server comes into play.

The D-Link DP-301U allows you to connect those older laser and inkjet printers to the wireless print server. Meaning everyone in your office will have access to the printers without the cables. Consider I work off a laptop and so do most others, walking around and being to print on demand is insanely convenient. You may not think so now… but that means you don’t have a wireless printer connection [otherwise you’d agree].

You can buy it from Amazon.com and includes free shipping [limited time] if you use a free shipping Amazon coupon. The unit is not refurbished.

This is indeed a great deal for everyone and you should buy it while this price is still so low.

Morse Code Beacon via USB Board

For those into home-brew programming projects, its easy to make a microcontroller spit out some Morse code with the post shown below. What makes [pavlin’s] take on this project interesting is that it resides on a tiny USB board with an ARM processor. The design for the board is available with single-sided artwork suitable for production using simple methods like toner transfer.

The STM device has a built-in USB bootloader. It can also act as a serial port, which makes the project very simple and a bit more flexible. The only external parts are a speaker and an opt-oisolator.

The program provides a command line interface over the serial port that you can use to program the message and set other options like speed and the delay between messages.

Sony Branded USB Turntable

CES, 2016. Sony releases a USB turntable, named HX500. Sony will provide backup- software for the Mac and PC and it connects via USB. From there, you can send the DSD (Direct Stream Digital) copies to your computer or device. Of course Sony would prefer you to play them back on their Hi-Res-playing Sony Walkmans.

The DSD audio is a lossless audio quality that will sound more full and rich than your downloaded MP3 file. Andy why not, vinyl records have been making a big comeback the last couple of years.

The USB is Write Protected: Why?

USB write protected means the USB cannot be written to. But why?

There are really only two reasons why a USB stick is write protected.

#1 The USB is corrupted in some way and is no longer working properly. It’s actually very easy to destroy a USB stick and the most common way is sending multiple write threads to the device. So for example, you decide to copy a bunch of files form your computer to your USB stick. While that data transfer is going on, you give another request to write data to the flash drive. If the second request doesn’t write protect the USB, then try sending a third command, all at the same time of course, and this will certainly write protect the drive.

#2 The USB is write protected by design. Meaning the content owner (person who put data on the drive) made the stick read only. Read only is another way of saying write protected.

Can I Connect a USB-C to a USB 2.0 Port?

USB Type C Connector

Question

Can I connect a USB Type C cable to an older USB 2.0 port?

Answer

No you cannot.

The USB type C socket is a backward compatible technology with respect to the protocol but it is not backward compatible in the physical connection. Meaning, the sockets wont fit, but with an adapter you will have no problem charge devices or trasnfering data.

Why

The USB-C connection was design for several reasons. Of course a new specification will always be developed to increase data transfer rates or introduce new features, such as increased power across the buss to charge or power connected devices. The main reason for USB-C connectors is size. With USB being the world’s most popular technology for peripheral devices, the Implementers Forum (with members such as Intel, Acer, AData, SanDisk, Lexar, Micron and many others) they wanted to insure the USB specification continued to be the #1 method for connecting the ever decreasing size of digital devices.

Nexcopy Introduces Write Protection for SD Cards

Nexcopy Inc., microSD DuplicatorLake Forest, CA — July, 2015 — Nexcopy Inc., introduces a new software suite which supports data locking content to secure digital media. The software function supports both full size Secure Digital card media and microSD card media. The data locking feature will turn the SD card into a read only card so data cannot be deleted or formatted off the device.

Write protecting, or data locking content to flash memory is an important security feature. With the Nexcopy software and duplicator, data can be copied to the memory card and as a final step the device will be write protected at the controller level.
