Teleport allows keyboard/mouse sharing between Macs

teleport

Teleport is a program for OS X that lets you share one keyboard and mouse between multiple computers – very handy for when you want to turn a macbook into a makeshift second display for your Mac desktop.  Before I discovered teleport, I was using synergy, which achieves almost the same result but requires an open Terminal window to launch and use it (synergy’s daemon functionality is broken in Leopard).  Teleport has some other advantages over synergy, including drag and drop file support (really cool!) and working mouse-wheel scrolling.

I initially had some problems with a short delay when moving the mouse from my desktop to the remote display, but I quickly resolved this by making a couple changes to the teleport configuration:

  1. Uncheck “Show bezel when controlling shared Mac” in the teleport control panel options, as shown below.  This actually makes a noticeable difference.
  2. teleport_config

  3. Disable the switch animation by executing this command in a Terminal window:
    defaults write com.abyssoft.teleport showSwitchAnimation NO

Now my pointer moves almost instantaneously from one display to the next, even with one machine on Wi-Fi.  Curiously, I only had to make the changes on the server side, I left the client machine preferences alone.

Hopefully this will help other folks who are having the same issue.

Microchip Internet Radio Demonstration Board

Microchip Internet Radio Demonstration Board

Microchip Technology, makers of the PIC microcontroller, have released a demo board for the 8-bit PIC18F67J60 that is pre-programmed to function as an internet radio receiver.

Anyone familiar with the blog knows that I have a special love for internet streaming radio, so it shouldn’t be a surprise that this demo board immediate caught my eye.

The demo board’s features include ethernet, a dedicated MP3 decoder IC, pushbutton user interface, and a cool OLED matrix display.  The PIC18F67J60 includes an ethernet PHY on-chip,  which makes for a very simple way to add network connectivity to the microcontroller.  Sadly, unlike my usual hacking platform, there isn’t any wireless on-board, but given the extremely small size and downloadable source code, I am really tempted to get one of these to play with.

Here’s a short video about the board by MicrochipTechnology on YouTube:

First open water test of the MFC

Madox Floating Camera (MFC)

A couple weeks ago, I posted about Madox, who created a floating camera platform based on an Asus WL-520gU wireless router and called it the Madox Floating Camera, or MFC.

Great news – he finished putting the MFC together just in time for the Australian Battle Group meet on June 6th and posted some pictures and videos of it in action.  Apparently the assembly involved a lot of duct tape and he had a few minor issues with the rig, but you can’t tell from the videos!

For technical details about this project, check out his MFC project page.

Here’s a sample video of scale warship combat as seen by the MFC:

(Note: your speakers are not broken, there is no audio!)

I really love this project and I hope to keep reading about it as Madox works out the bugs.

Madox – Keep up the good work!

Revised McMaster-Carr website is faster, allows deep linking

New McMaster-Carr Website

Great news!  McMaster-Carr has revised their spectacular online catalog to allow deep linking.  The site seems to be much snappier overall so I suspect there have been some other less obvious improvements under the hood as well.

Now if only we could get the folks at Digikey to adopt McMaster’s splendid drill-down search interface, we could revolutionize the mail order electronics parts industry…

I can dream, can’t I?

Sutro Tower no longer transmitting analog television

As part of the nationwide DTV transition, on Friday, June 12th, Sutro Tower ceased all analog television transmissions by powering down the three main analog TV antennas atop San Francisco’s iconic three-legged broadcast radio tower.

This change is reflected by their status page, which now shows the top of the antenna mostly dark with the exception of a few FM radio stations, as shown below.  The DTV mast in the center of the tower is providing temporary digital television service during the tower’s massive DTV conversion project.

Sutro Tower Antenna Status

According to Gene Zastrow, Sutro’s general manager, the existing analog television antennas will be replaced with new primary DTV antennas over the next several weeks.  This could make for some great photo opportunities if the weather is decent, as I expect that given the size of the antennas there will be some serious equipment being used on and around the tower.

Join the resistance.
