[Trax] sent in his writeup on this RF modem with built in 250mW amplifier. The original power of the RF transceiver was around 10mW, his final results after testing were nearly 250mW. He was able to to easily transmit data over 1000 meters using his test setup. He states that he was actually able to achieve this without an antenna on the receiving side. That’s pretty impressive performance. It’s also worth noting that he soldered all of the components in place using a home clothing iron and some soldering paste. That must have been fairly tedious.
Almost exactly a year ago, we posted the random USB capslocker. [Garrett] has revisited the idea to build a smaller, neater version. He has posted the build process to give us an idea how he goes about building things. The overall build is quite nice, but part if its neatness can be attributed to the fact that he had access to an Epilog laser cutter. If you think you might be using one in the near future, this is a great writeup for you.

[Eddie], who made the Mac Logo LCD Mod, had posted a step by step tutorial on how to do it yourself. He basically just fully disassembled his MacBook, popped out the logo, put one from an iBook or Powerbook, then mounted a small LCD back there and routed it into a USB port internally. He says the extra electronics cause a tiny bulge in the monitor casing. We wonder if this couldn’t lead to stress damage on the main LCD in the long run.
