Ana Sonde Assembly What is the Ana Sonde

Ana. Sonde Assembly

What is the Ana. Sonde? *Reads temperature, pressure, and humidity data from the atmosphere *After it is sent into the atmosphere, it radios the data back down to a computer on earth *This data can be plotted and used to determine the weather in the upper atmosphere, what type of pressure system is located above the launch location, etc.

What Equipment Do I Need to Operate an Ana. Sonde? • Ana. Sonde Kit – Circuit Board – Components – Parachute – Sun Shield • Hardware – Antenna – Hand-held radio, cable – Computer – Ana. Sonde software (free!)

A Quick Lesson on “How to Solder” Soldering is the joining of metals by a fusion of alloys which have relatively low melting points Be VERY careful! Soldering iron is HOT! Tie up your hair! You do not want it hanging in the way of the hot iron! Wear Safety Goggles at ALL times! Eye protection is VERY important!

1. Apply a very small amount of solder to the soldering iron's tip. This is called tinning. It makes it easier to solder. (Note: This is NOT the solder that will make the connection). 2. Place the part on its correct spot on the board. Bend the leads to hold it in place. Once the component is secured to the board, heat up the component lead and the board.

3. Once heated, touch the solder to the lead and board, NOT to the iron tip. 4. Once solder is applied, stop applying solder and then remove tip. Allow to cool. Once the part has cooled, clip the ends of the part so they don’t stick out far.

Soldering Tips • Keep your iron on the holder when not using. It WILL burn something if placed somewhere else. • If you create a solder bridge by accident, you can use copper braid to pull out some of the solder by placing it over the bridge and holding the soldering iron to it for around 10 -20 seconds at a time.

Soldering Tips (Continued) • Finally, you do NOT need to push the parts all the way down onto the board. In fact, it is better if parts such as D 1, U 1, the transmitter, the speaker and the temperature sensor remain above the board a little. (See pictures as you go along. ) Things such as U 2, C 1 & 2, X 1, R 1, S 1 and the battery snap should be placed as close as they can to the board.

Do NOT let solder bridges to occur. Make sure you put on enough solder to make the connection but not so much the circuit is shorted. You especially DON’T want it to look like this!!! Not enough solder Too much solder

You do want to make sure that it looks like the below picture. No gaps between the board and the part, but no bridges either. Perfect amount of solder

Let's Start Assembling Our Ana. Sonde! 1. Plug in soldering iron and place on stand 2. Wet sponge if necessary 3. Look at circuit board and identify: − Component side (with white labels) − Solder side (no labels) 4. Throughout assembly process, can bend legs, clip, or tape parts to hold in place

Installing Socket for U 2 Notch U 2 is direction sensitive! Line up notch on U 2 with notch drawn on the circuit board!

Tips for Socket Installation Can clip U 2 to board using alligator clip Can see small legs coming through to solder side Solder goes on this side, 8 joints total

Install R 1 and D 1 Step 1: Bend R 1 to hold in place. Solder one leg first. Then, reheat the solder and push all the way through. R 1 should be very close to surface of circuit board. Step 2: Solder D 1 (the LED) in the same manner used for R 1. Your circuit board should now have U 2, R 1, and D 1 components installed. CAUTION! D 1 (the LED) is direction sensitive. Be sure to solder the long leg into the positive (+) opening on the circuit board.

After R 1 / D 1 Installation

Install U 1: Be Careful! Caution!! U 1, the voltage regulator, looks exactly like the temperature sensor! Look for the label on the flat side: 78 L 05 The U 1 regulator is direction sensitive. The flat side of the black end should match up with the flat edge of the white label on the circuit board. U 1: Voltage Regulator Do not push in too far, leave some height in the legs

C 1 and C 2 are NOT direction sensitive. C 1 and C 2 go on both sides of U 1.

S 1: On/Off Switch OFF ON MAKE SURE TO SET SWITCH TO THE OFF POSITION!

X 1: 4 MHz Resonator Bend one leg to hold in place. Solder one leg. Reheat solder and push resonator all the way through. Solder remaining two legs.

Installing the Temperature Sensor Ground V out + Flat Side The label on the flat side of this one should read: LM 19

Final Instructions • In the Buzz-E, the speaker must go where the transmitter would (U 3), however it will go in the first two consecutive holes, NOT in the first and the last!

Final Instructions (Continued) • The microcontroller has a little dot on one end, this end will be the same direction as the notch in the socket. This must be pushed in all the way. (See picture on following slide. ) • Finally, the battery snap must have the red lead going to the positive and the black to the negative. Thread the lead up through the bigger holes on the sides of the + and – and then stick them back down through the + and – holes accordingly. (See picture on next slide).

The Final Components! U 3: Transmitter, Antenna Wire, Battery Snap, U 2: Microcontroller Antenna Wire U 3: Transmitter Speaker Microcontroller Battery Snap
