Frequency Change on Futaba Receiver R138DP (PCM) originally tuned for 72Mhz

Futaba has discontinued their 50Mhz receiver Model R138DP, however its available in frequency range 72Mhz.  I have Futaba Transmitter 9-Cap operating on 50Mhz. I want to convert all my 72Mhz receivers to 50Mhz since there is nobody using 50Mhz in our model club so no chance of Frequency Clash, more over I experience Glitches on 72Mhz but non on 50Mhz.

Facebook app

I've been working on an app for facebook. I guess you could say it's in closed beta. Anywho, I need a few people for a test group. It is a TNG-Era game, that so far has the option of: The Borg, The UFP and the Romulan Star Empire. Also, I would gladly accept suggestions from those who don't use facebook.

Last Meal

I'm a television junkie and I recently watched an episode of King of the Hill in which Dale, Bill, Boomhauer and Khan get together to make what would be their last meal, if they knew they were going to be executed the next day.  I was thinking about this....what would my last meal be? A Japanese bento with tonkatsu, teriyaki chicken, tempura veg, various sushi, Grandma's green chile, and her black mole (mo-lay) and my Mom's rice......and some Ghiradelli dark chocolate. What would your last meal be? I think I want to get some friends together and do my own "Last Meal Party."....In time for Halloween.

Having trouble measuring accurate voltage with arduino.

For a week now I’m trying to get very precise voltage readings with no luck so far. I’m using a voltage shunt regulator (LM431) for reference but still. My goal is to read values low as a 1mv change. I’m using a voltage divider to convert 38 volts to 4v (According to my vref). I've read that 10 bit ADC in atmega328 is enough for this job. Is it or am I doing something wrong? Thanks P.S i have made a lot on changes to my circuit so please go over to my new link to get up to date. Ive read all of your feedback and tried to implement it. Thanks a lot for all your answers.  LINK:

How To Build RFID walk Through Sensors (Stands)?

Hi All, I am planning to build an School Attendance System, RFID Walk Through Reader, So i need help from your end how can i built it (Step by Step Processs and Need of Material i need to use for it). My Planning: Need to built an RFID Walk Through Reader, means, suppose if a student ware an RFID Card in his neck and when he pass through from RFID Reader stand (it may be 3 meters distance between ID card and Reader) then automatically this RFID Stand will read the students information from his ID Card and send SMS to his Parents automatically. will you please send me Step by Step Process how to build it and what type of material i need and what type of Software i need to develop, my mail id:, i hope i can get my answer as soon as possible from your end.

One Small Slip...

Two Bangladeshi newspapers have apologised after publishing an article taken from a satirical US website which claimed the Moon landings were faked.The Daily Manab Zamin said US astronaut Neil Armstrong had shocked a news conference by saying he now knew it had been an "elaborate hoax".Neither they nor the New Nation, which later picked up the story, realised the Onion was not a genuine news site.Both have now apologised to their readers for not checking the story."We thought it was true so we printed it without checking," associate editor Hasanuzzuman Khan told the AFP news agency."We didn't know the Onion was not a real news site." The Onion article claimed that Armstrong had been convinced by a website written by a part-time librarian;"It only took a few hastily written paragraphs published by this passionate denier of mankind's so-called 'greatest technological achievement' for me to realize I had been living a lie, " said a visibly emotional Armstrong, addressing reporters at his home. "It has become painfully clear to me that on July 20, 1969, the Lunar Module under the control of my crew did not in fact travel 250,000 miles over eight days, touch down on the moon, and perform various experiments, ushering in a new era for humanity. Instead, the entire thing was filmed on a soundstage, most likely in New Mexico."Obviously, this is a major embarrassment for the newspapers involved, and clearly shows how modern "journalism" is really just copy-paste-spin (witness The Daily Mail's recent "pregnant immigrant" slant on UK population data)You've got to wonder, though - how much other net-sourced nonsense has made it to the headlines as "news"?The Onion articleManabzamin newspaperNew Nation (Tagline: "Bangladesh's Independent News Source"!)

Having trouble measuring voltage with arduino.

I have posted this question before but I’ve made a few changes with my circuit with no luck. I’m trying to make a variable lab bench power supply with an lcd screen to read voltage and current while adjusting them. I’m using TL431 to have a 2.5v Vref and  a op amp in voltage follower configuration with 10M and 1M trimmer (Divider) on the input to finely calibrate 38v down to 2.5. The op amp is acting like a buffer. This is the code I've come up with: float volt; int sum = 0;                   unsigned char sample_count = 0; #define NUM_SAMPLES 10 void setup() {   analogReference(EXTERNAL);   Serial.begin(9600); } void loop() {   while (sample_count < NUM_SAMPLES) {    sum += analogRead(A0);    sample_count++;    delay(10);     }    volt = ((float)sum / (float)NUM_SAMPLES * 2.5) / 1023.0;     Serial.println(volt * 15.2 ,3);     sample_count = 0;     sum = 0; } Parts list: LM358 (for now, will upgrade to a unity gain stable op amp) 10M 5% resistor 1M trimmer Arduino Mega (Will use a pro mini in the final circuit) Breadboard (Will this effect my readings?) TL431 (2.5v Vref) Yes I now the LM358 is not suited for this application but I don’t think this will affect my readings by much, about 5% maybe. Will it? This code is gives me OK values at start but when I start to decrease/Increase the voltage. It lags behind and offsets by 1-2 volts on the reading. My goal with this project is to read (LIVE, meaning while changing voltage with buttons and see it change without any offset/lag) Voltage with a resolution of +-5/10mv accuracy and also read current (But thats for a later day). One last thing, I’m 16 so a lot of electronic terms tend to go over my head so please while giving an answer keep it simple if possible. Thanks :D
