DIY Webradio – RadioduinoWRT

Raffael Herrmann from en.code-bude.net stuffed the guts of his RadioduinoWRT project into an old piece of stereo equipment. Inside the box he has about $100 worth of electronics including a WRT router, an Arduino Mega and an ethernet module. The result is a great looking component that can stream internet radio without having to keep a computer running to play it.

“Once the basic idea to build a web radio myself was fixed, I thought about the components to be installed. So initially I also included a Raspberry Pi to discussion. Finally, I have decided on a combination of the TP-Link WR703N router (about which I have already reported several times in my blog) and an Arduino Mega.

This decision had several reasons – first, I had both the router and the Arduino still in my parts box and on the other I wanted to implement the projectas cheap as possible and on minimal hardware. Certainly a realization with a Raspberry Pi would have been possible, but this would have been more expensive than the TL-WR703N and the Arduino Mega together. Furthermore the hardware of the Raspberry is almost “oversized” for the project requirements.”

Repost: blog.g4ilo.com/ – What weather station?

Link to Original Post

A few days ago my Fox Delta WX1 Micro Weather Station stopped working. As it turned out, I just had to switch off the power and switch it on and it started working again . But while I was waiting for the rain to stop so I could go out and look at the device I began thinking about getting a better weather station – one that measures wind speed and direction and rainfall as well as temperature, humidity and pressure.

When you start to look at weather stations the choice is overwhelming. My first priority was that it should work with APRSISCE and generate the file wxnow.txt that it uses to update weather objects. That requirement led to the stipulation that it should be compatible with the free weather software Cumulus, which creates the required file. There is a list of weather stations that work with this software, which narrowed the choice down a little. After reading many reviews the best choice seemed to be the Davis Vantage Vue. Unfortunately this cost about four times more than I was willing to pay, so it was back to the drawing board.

The weather stations made by the Chinese firm Fine Offset and sold under the Watson brand name seemed to meet my criteria at a more reasonable price. However, browsing through the reviews on Eham.net and elsewhere there were quite a high proportion of dissatisfied users. Complaints about anemometers that stopped rotating, poor wireless reception and so on. With weather stations as with everything else, it seems, you get what you pay for.

Despite the reviews I am tempted to get one of the Watson W6861 solar weather stations. But before I did I thought I would take the opportunity to ask my readers for their experiences. Many of you must have home weather stations. So which ones are good, which are bad and which should be avoided at all costs? I await your comments with interest.


Repost: hackaday.com – GoPro hack delivers live video feed for piloting your Quadcopter


The GoPro line of HD cameras seem like they were specifically designed for use with quadcopters. We say that because the small, light-weight video devices present a payload which can be lifted without too much strain, but still have enough horse power to capture video of superb quality. Here’s a hack that uses the camera to provide a remote First Person View so that you may pilot the aircraft when it is out of your line of sight.

The camera in question is a GoPro Hero 3. It differs from its predecessors in that the composite video out port has been moved to a mini USB connector. But it’s still there and just a bit of cable splicing will yield a very clear signal. The image above shows the camera in the middle, connecting via the spliced cable to an FPV transmitter on the right. This will all be strapped to the quadcopter, with the signal picked up by the receiver on the left and piped to a goggle display worn by the pilot. You can see the cable being construction process in the clip after the break.

The Kindle Touch…

kindle-touchFor years now I’ve been a pretty loyal Amazon customer, for good reason. Amazon.com is a very useful web-store. They have very reasonable prices, a lot of times better than in store prices. The Prime service Amazon has is great, and for me just keeps getting better. Basically it’s like a VIP card for Amazon. You will get $3.99 next day shipping and free 2-day shipping on any products in an Amazon warehouse and now some outside stores are Prime certified and offer the same. And there’s more to Amazon as well.

Also for years now I have been coveting myself a e-reader. Sony started for me, but truthfully I’ve always hated Sony so I didn’t get one. Then a few years ago Amazon started offering there own design e-reader. The Kindle. By now there’s been many Kindle’s. And among models different versions and trim levels. This has been a long road for me. See it started out that they were out of my budget range. But then around Kindle 3 they brought it down to the sub 150 range I believe. And inherently that’s not a lot of money. But I’ve always worried and felt in my gut that I would get it and not use it. And I don’t want that to happen for a gadget that does cost that much. Well last week I boiled over. Amazon now has Kindle models sub 100 bucks. So I went to Office Depot and bought myself a Kindle Touch they had on sale for the price of the regular Kindle.

Now that I have my Kindle Touch I realize that I wish I’d done it long ago because I don’t think I can live without it anymore! I’ll go a review after I’ve had it a little longer.
