Note that the first bunch of components in the list are SMDs and come soldered to the board (that is, I solder them for you). US$67  US$57, free shipping to Nort

In this tutorial no skill is required, we'll just use the password recovery process with 3 fake profiles. (The fake profiles should be at least three weeks old) . For this you need to make 3 fake profiles on Facebook, and the victim that you want to hack should be added to the friend's list mutual friends would be nice. Read more »

To test the XBee on Wise Clock 4 I used the sketch below (upload it to the board; display is not required). int nCount = 0; void setup() {   Serial.begin(9600);   Serial1.begin(9600);   Serial.println("WC4 XBee ready for comm...");  } void loop() {   // read from port 1, report characters on port 0:   while (Serial1.available())   {     char inChar = Serial1.read();     Serial.print(inChar);    }   Serial1.print("WC4 XBee transmit ");   Serial1.print(nCount++);   Serial1.print(", ");   Serial1.println(millis());   delay(3000); } Notice the use of Serial1 instance to talk to the XBee, since this is connected to the second hardware serial port of the ATmega644P (D10/D11, pins 16/17). Had Sanguino offered no support for the second USART, we could have used NewSoftwareSerial library . The second XBee is linked directly to a terminal (e.g. HyperTerminal in Windows, or Terminal panel in the X-CTU application from Digi). I personally used the  XBee Adapter  fro

Hello friends! You might have many software on the internet which is used to lock the files and folders. Also you might have seen batch programs that also does the same job.

Using two 3216 displays together is an almost trivial hack. I wanted to make sure it works fine with the Wise Clock 4 board. The video below shows the new board running both " Night and Day " and " Wise Clock 3 " (merged into one sketch, of course). In practice, one can now build the " Dual Screen Wise Clock 4 " with the two displays placed on opposite sides (back to back), or one next to the other (as shown in the video). A crazy idea would be to have 4 displays placed in a square :)

Thank you for the honor, Make: magazine! Here is the actual Make: web site dedicated to kit reviews.

The new Wise Clock 4 board has two main improvements over Wise Clock 3 : support for the XBee family of wireless RF modules (XBee, XBee Pro, XBee Wi-Fi, and the similar foot-printed Roving Networks WiFly RN-XV ); ability to easily connect a second display ; this is achieved by moving the power connector on the "right" side, plus bringing the extension display connector closer to the bottom of the board. Wise Clock 4 is "almost" compatible with Wise Clock 3 . To run the existing sketch on Wise Clock 4 , two changes are required: Plus button is now on D3 (D2 is now designated for interrupts from RTC); D15 is now connected to the CS line of the display, replacing D11, which is now used for communication with the Xbee module. As can be noticed from the photos, a few more components are in SMD package (necessary to keep the size of the board to a minimum, to fit in the back of the 3216 display): the level shifting buffer 74HC125 ; three optional LEDs: 2 for the XBee

Purchase any of my kits and you can get one  (or more, if you ask nicely :) freebee from this page (just email me with your choice). I am currently giving away a few "surplus" boards and LED matrices. Shown below are, from left to right: PCB for the LED matrix shield ; PCB for Wiseduino rev. 1.7 ; PCB for the Dual bi-color LED matrix shield rev 1.4 ; PCB for the Dual bi-color LED matrix shield rev 2.0 ; You can also get the PCB for DWex , a small Arduino + RTC, that you can make into a DIY pocket/pendant watch. This board is mostly SMD, but not difficult to solder with a little exercise. Any of the above PCBs can be used as originally intended (for kits), since there is nothing wrong with them (as far as I know). The challenge in building the LED matrix shields is in finding the right matrices (which is almost impossible, since they were "kind-of" custom made for me by a Chinese LED company some time ago). Nevertheless, one can connect other (compatible, that is co

I am very "productive" lately (or maybe just wasteful with my time): this is my sixth post in as many consecutive days. I recently "discovered", in a design shop, this great looking travel clock made by Lexon . Things I like about it: beautiful shape/form/dimensions (low profile, small, light) and nice finish (brushed aluminum); apparent simplicity, with just one large(ish) button on the top and the lesser-used buttons placed on the bottom; LCD screen covering the whole face, showing more than the time (date, day, temperature, alarm); low consumption; powered by 2 CR2032 batteries, one for the clock, the other for the LCD backlight; attention to detail is everywhere, including the bottom rubber bumpers: the front ones are higher than the back ones, as seen in the next photo. This Lexon clock should be good inspiration for clock makers and clock designers. I hope one day my Wise Clock N will be as great as this is :)

This  is my original post on LunaTik . Coincidentally (I guess the Apple iPod Nano team thinks that they found the ideal shape and size), the latest, 7th, generation of iPod Nano has the exact same dimensions as the one it replaces (and for which LunaTik was designed). So, LunaTik and TikTok get a new (and well deserved) lease on life, from Apple itself. More, LunaTik is actually mentioned in one of Apple's presentations , officially endorsing the brand. Actually, even the current (6th) generation iPod Nano can be software-upgraded through iTunes with 16 new clock faces (some of them shown in the photo below, courtesy of LunaTik team, sent by email via kickstarter). But this is not all. As I anticipated, watch "modules"  (shown below) are being developed to be hosted by LunaTik. This could become the flagship of the designer watches. Can you imagine high-end watchmakers producing watches that fit LunaTik? How far fetched is to see a custom made-for-LunaTik Omega, for exam

This would make a nice replacement for the original glass-domed WiseClock . I named it CubeClock for the simple reason that it is encased in a baseball display case, found on ebay for about $5. It includes Wiseduino (with on-board RTC), a LiPo battery shield (I used the one from seeedstudio, but others should work too), a prototype shield with the cheap "orientation sensor" introduced here , and the bi-color LED mini-display shield . The bottom board is the Wiseduino , secured to the box with 2 screws. The other shields are just stacked on top of each other. The battery shield from seeedstudio, discussed here , uses a 1,000mAh LiPo battery (did not come with the shield), attached to the shield itself with plastic ties. The clock can be turned on or off (to save the battery) from the power switch on the Wiseduino . CubeClock can also be powered through the USB cable plugged into the battery shield (which also charges the LiPo battery), as shown below. A closer look is shown

It may have occurred to you to find an interesting device with LEDs, only to realize that it uses components that are obsolete and cannot be sourced anymore (or if they can , they may be prohibitively expensive). Such is the case with STP16DP05 in DIL (dual-in-line) package, used in a few kits by EvilMadScience.com and ModernDevice.com . STP16DP05 is a 16-bit LED sink driver still manufactured in SMD, but obsolete (and impossible to find) in "through-hole". If you want to build such open-source popular kits as " Meggy Jr RGB " or " Peggy 2 ", you will have to re-design the board, replacing the DIL package with the SMD. What if you already have the PCB and are constrained to use the DIL version? The immediate solution that comes to mind is to use a breakout board with an SMD. Problem is, I couldn't find a breakout to the "narrow", 0.3", DIL format; they are all 0.6" wide. So, the only choice I had was to use a replacement DIL for t

This should be an update to a previous post (I am too lazy to edit that nicely). I bought two LiPo battery shields, one from Seeedstudio , one from cutedigi . None came with a LiPo battery. I guess it is assumed that the user selects the battery that suits his needs. My main need was for a battery that fit between the headers and was lower than the height of the headers, so that another shield can be stacked on top. Guess what: it's not easy to find such a LiPo battery. The round, AA or AAA-compatible ones, are out of the questions because of their size. The only candidates would be those silvery-flat-rectangular ones, as those pictured below. The best match for the " Solar charger " from seeedstudio is the third LiPo in the photo, with a capacity of 1,000mAh. For comparison, 3 AA rechargeable batteries (1.2V each, making a similar 3.6V) usually have a capacity of 2,200 - 2,800mAh. So this flat LiPo battery would be a bit less than half of the capacity of the space-consu
