Zedomax DIY 115- HOWTO establish serial connection with PCs bluetooth 2.0 with ACODE-300
Okay, today at work I have been getting a lot of calls on how to connect the ACODE-300 serial to bluetooth converter module to a PC or Laptop with bluetooth…
Well since the ACODE-300 is bluetooth 1.1 compliant and bluetooth 2.0 is backward compatible, the ACODE-300 should have no problem in establishing serial connection with a PC.
Why do you need this?
Well let’s say you are using an MCU (Microcontroller) such as AVR, PIC, Make Controller, Basic Stamp, or CUBLOC. If you were to use the ACODE-300 module on the MCU side and if you wanted to write a customized C++ or Visual Basic program on your PC to control the embedded module, you would need to know this.

DIY HOWTO - Wireless Color changing light project with PIC
Here’s a cool color changing DIY I found by google-ing…
Wow,” you say, “how can you expect to make something wireless and still have it cost less than fifty dollars?” Well I’m glad you asked. “But I didn’t ask,” you say, “I’m just reading.” Do you want to argue, or would you like to hear about my solution? That’s what I thought. For the job of fairly-reliable wireless communication, I turn to my old friends the TX433 and RX433 modules. These are complementary transmitter/receiver pairs that operate on the seldom-used 433.92 MHz frequency. Another strong plus is that the devices are very small. The transmitter (TX433) is about the size of my thumbnail (though to be fair, I have sexier-than-average thumbnails) and will fit inside a standard 9-pin D-Sub hood. As if that weren’t enough, the transmitter also has very loose power requirements (3 to 12 volts). The receiver is slightly larger and is quite finicky about its power (more on that later). Back in the day you could obtain them through TechAmerica, but now TechAmerica has turned into RadioShack.com, and along with RadioShack, their inventory has decreased to the point of phasing out these wonderful little modules. So doing a search on “RX433″ revealed to me the only other online supplier of these miracle devices, a company called QKits in Canada. They go for about $6 american each. I also found some on eBay at comparable prices (and they might be more reliable modules).
Networked Air conditioners with AI and remote controllable using PDA or cell phone
Cool high tech air conditioners…
We’re not exactly sure what gives an air conditioner “artificial intelligence,” but our buds at AVING claim to have found one at the Korea Electronics Show, now underway in Seoul. Haier Korea, the Korean branch of the Chinese manufacturing jack-of-all-trades showed off two models, including the KFRd-72LW/O (”standard type”) and the KFRd-35GW/O (”wall mounted type”). Both come with an LED display (but what doesn’t these days?), an air purifier, an anion generator and dehumidifier. And if that wasn’t enough, how about the fact that both air conditioners can be controlled via cell phone or PDA? Yeah, we know you want one — sadly, we don’t know when these will be released, nor how many South Korean won you’ll have to dish out to get ‘em. Keep reading if you’re interested in a close-up of the display, or if you just like watching seals slide down snowy hills on their tummies…

Okay, I grabbed a pitchfork for halloween for a dollar at the new $1 store in SF Fillmore district…
I didn’t really have any ideas but after I put in bunch of LEDs on the pitchfork, I realized you can display letters too!
Anyways, this is the most fun diy so far.

DIY HACK HOWTO - Snoop Doggy USB
Here’s a cool howto on snooping your USB for linux hackers! Yes, modprobe is very useful…
Rad, Quiet Earth has a good how-to on listening in to what’s going on over USB, great for reverse engineering weird USB doo-dads… - “This is intended to be a howto to debug usb transactions under linux, or simply to reverse engineer propietary usb stuff. If you need to reverse engineer a windows only usb driver, you can do it easily running vmware under linux. We can snoop the usb traffic from windows using usbmon which is part of the linux kernel since version 2.6.11 (I think). Previous to that you had to use patches.”
Cool RC Foamy Flying Wings
Here’s cool DIY plans that you can make some RC Foamy flying wings!
Please send me some samples to Max!
All the 3D maneuvers are mixed up with conventional aerobatics to make a breathtaking routine…. But unlike other types of flying, a specific plane is needed. To fly 3D, you have to have a plane that’s has lots of pitch and yaw control. Elevators taking up 50%-60% of horizontal stabilizer’s surface is a must. They need to be able to travel to 45 deg in either way. The same is true for the Rudder. Ailerons should also be large, but will require less throw than the rudder and elevator.Hangar 9 makes the CAP 232…. For larger planes, it is a great choice for 3D flight. Our little planes do all the maneuvers shown, and just as well as the big planes. Most people practice the tricks with the little guy, and then when it is mastered, feel comfortable moving up to the BIG plane for airshows.
