MLB.TV still stupidly refusing to offer me a product that I want to buy…

February 22, 2012 | Baseball, Rants and Raves | By: Mark VandeWettering

Two years ago, I complained that MLB.TV’s black out rules basically robbed them of a chance to get $120 of my hard earned cash in exchange for a product which they supply to others in the U.S., but which they refuse to sell me. Fast forward to today, and nothing has changed: I still can’t […]

Why I am not going to play Skyrim any more…

February 22, 2012 | Computer Games, Xbox 360 | By: Mark VandeWettering

Okay, a diversion from my regular topics. And that’s what computer games are for me: a diversion. I play them because I like to be diverted from my work and from even my normal bits of hackery and play. I tend to play games with a strong story component, like the Zelda games on Nintendo, […]

50th anniversary of Glenn’s orbit aboard Friendship 7

February 20, 2012 | Space | By: Mark VandeWettering

50 years ago today, American astronaut John Glenn completed three orbits of the earth aboard Friendship 7. Glenn would later become Senator, and would return to space aboard the Space Shuttle Discovery as part of the STS-95 crew, becoming the oldest person to fly into space. These three orbits started fifty years of an American […]

Examining the output of a simple remote-keyless-entry transmitter…

February 20, 2012 | Amateur Radio, Arduino, electronics | By: Mark VandeWettering

Yesterday I was looking (sadly unsuccessfully) for some BPW32 photodiodes that I know I have somewhere, when I ran across some of 434 Mhz transmitter modules from Sparkfun (now a retired part) that I had never used. These little $4 transmitters are commonly used for remote-keyless access or similar applications. They have just four pins: […]

A simple beacon keyer for the ATtiny13

February 18, 2012 | Arduino | By: Mark VandeWettering

Roger, G3XBM built a simple beacon for light communication using a K1EL beacon keyer chip and a handful of other components. I didn’t have any of those chips around, but I did have some Atmel ATtiny13s lying around. I hacked this simple program together to send Morse code in two different ways: on pin PB1 […]

Spray-on Antennas? I say “Spray-on Bunkum”

February 17, 2012 | Amateur Radio, electronics, Rants and Raves | By: Mark VandeWettering

Thanks to John, who pointed out that this post was mangled. Fixed now. I wasn’t going to mention this one, but Dave, Chris and Jeff over at The Amp Hour brought it up on their most recent podcast, but other than Jeff’s somewhat enthusiastic declaration that he thought it was BS, I don’t think they […]

More on ATtiny programming…

February 15, 2012 | Arduino, electronics | By: Mark VandeWettering

Last night’s hacking adventure was inspired by a couple of recent posts from Roger, G3XBM having to do with light based communication. The first was his simple beacon design: it’s just a keyer chip, a MOSFET, a voltage regulator, and some (beefy) current limiting resistors. Roger used this beacon to do some non-line-of-sight communications via […]

Web-based control of an RGB LED via the Nanode, an Arduino compatible microcontroller

February 12, 2012 | Arduino, electronics | By: Mark VandeWettering

Okay, I finally got some time to record a video about a simple little webserver project I hacked together earlier this week. My wife Carmen got me a Nanode kit from Wicked Device around Christmas. These are Arduino compatible development boards which include a Microchip ENC28J60 Ethernet device to enable web connectivity. One slight drawback […]

Boring statistics re: brainwagon

February 6, 2012 | Blogging | By: Mark VandeWettering

Okay, today is February 6, which means that my revolvermap that you can see over in the left margin has been up one entire year. Right now, it’s showing 148,950 visits since it’s inception. I suspect a couple of thousand of those are actually me, but I’m pretty happy that so many people stumble their […]

maniacbug is an Arduino wizard…

February 1, 2012 | Arduino | By: Mark VandeWettering

Ken Boak was nice enough to gift me with a pair of Nanodes when he was out visiting last month. Much to my embarrassment, I haven’t had much time to play with them, so tonight I tried to do a bit more research to figure out how I could use them in some more advanced […]
