WE ARE HAVING TROUBLE GETTING DS9 SOFTWARE TO RUN WITH CYGWIN64. WHAT VERSION OF DS9 WILL WE NEED TO KNOW HOW TO USE FOR THE EVENT? SINCE WE DON'T HAVE INTERNET ACCESS AT THE COMPETITIONS WE WILL NOT BE ABLE TO USE THE JS9.

Because the event will be pen and paper, only printouts (or screenshots) of DS9 will be used. As a result, teams do not have to have DS9 on their computers to compete. Instead, if you cannot download DS9 simply use JS9 (the online tool) to practice for the competition. What is tested instead is students familiarity with the programs output and how to analyze/interpret that output. So however you get it to run on your personal, school, or library computers (and whichever version you use) is really a fine way to gain that understanding.


Ecology

(Section: 3 / Paragraph: b. / Sub-Paragraph: iv. / Line: 2)
11/03/2016
"SIMPSON INDEX" CAN BE LOOSELY APPLIED TO 3 DIFFERENT VALUES (AND CALCULATIONS) DEPENDING ON THE AUTHOR/SOURCE: SIMPSON'S INDEX, SIMPSON'S INDEX OF DIVERSITY AND SIMPSON'S RECIPROCAL INDEX. THIS SHOULD BE CLARIFIED.

Students should be familiar with all three. If used for the National competition the national supervisor will specify which is being used. We have chosen to define the Simpson index, p as the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N), Σ is still the sum of the calculations, and s is the number of species. This information can be found on the files distributed at coaches clinics and will also be on the SO website once the clinics are over.


Electric Vehicle

(Section: 2 / Paragraph: c / Line: 1)
11/14/2016
CLEARLY BATTERIES MUST BE LESS THAN 9V, BUT CAN WE USE STEP-UP REGULATOR TO GENERATE 12 V?

No, the voltage across any two points ≤ 9 V as stated by the manufacturer labels. If a step-up regulator steps a 9V battery up to 12V, this would be a violation.
(Section: 2 / Paragraph: g / Line: 1-2)
11/04/2016
HOW IS "LEADING PART OF THE VEHICLE" DEFINED? IS IT THE FORWARD-MOST PART IN THE DIRECTION OF THE VEHICLE'S TRAVEL OR THE CLOSEST PART TO THE TARGET POINT?

The "leading part of the vehicle" is the forward-most part in the direction of the vehicle's travel.

(Section: 5 / Paragraph: j / Line: 1)
11/03/2016
IS THE VEHICLE PERMITTED TO BE PROPELLED BACKWARDS OUTSIDE OF THE RUN TIME (AS DEFINED IN 5K)?

No. The rule is clear. ...please see rule 5.g.


Forensics

Rule 2.a.xv: should read: "Each team may bring five 8.5" x 11" sheets of paper 5 (both sides) containing information in any form from any source (sheet protectors are permitted)." (21-Nov-2016)


Helicopters

Section: 3 / Paragraph: f / Line: 2)
11/14/2016
WHAT DEFINES A SINGLE BLADED ROTOR? WOULD A SINGLE STICK OF WOOD PROJECTING OUT HORIZONTALLY FROM THE BODY BE CONSIDERED A "LIFTING SURFACE" THAT "ROTATES ON A COMMON PATH AROUND A VERTICAL AXIS"?

No, that would not be considered a lifting surface. To be considered a lifting surface, it must contribute lift to the overall flying assembly. An easy way to demonstrate that would be to demonstrate flying it with and without the surface, if the surface is not present then the flight would be significantly different.

NJIT Regional Only: The Namoli Center dimensions are 200' x 107'. 16' 8" high at the lowest point and 33' high at the peak. This event space will be shared with the Wright Stuff event. It is not possible to retrieve any devices that get stuck in the beams. We cannot control the ventilation system in the event room and we cannot control entry/exit to the room. (21-Nov-2016)

Union County College Regional Only: The Gym dimensions are 60' x 90' and 19' 10" high at the beams. This event space will be shared with the Wright Stuff event. It is not possible to retrieve any devices that get stuck in the beams. We cannot control the ventilation system in the event room and we cannot control entry/exit to the room. (21-Nov-2016)


Hovercraft

Rule 4.i: should read: "Brushless motors and integrated circuits are not permitted, unless they are an integral part of and are imbedded into a commerically available electronic or computer cooling fan." (21-Nov-2016)

---

(Section: 4 / Paragraph: k / Line: 1)
11/07/2016
CAN TEAMS USE A REMOTE CONTROL TO START AND/OR STOP THEIR HOVERCRAFT?

No, as any remote control system would violate either the dimension requirements or the prohibition on integrated circuits.

(Section: 4 / Paragraph: h / Line: 1)
11/07/2016
CAN WE CONNECT TWO 9V BATTERIES IN PARALLEL? VOLTAGE ACROSS ANY POINTS WILL NOT EXCEED 9V AS THEY ARE CONNECTED IN PARALLEL. THIS JUST GIVES US HIGHER CURRENT CAPACITY TO DRIVE TWO MOTORS.

Yes, this would be allowed.

(Section: 1 / Line: 1)
11/07/2016
DESCRIPTION STATE "MAY CONSTRUCT". CAN STUDENTS USE COMMERCIAL KITS OR MODELS OR SHOULD THEY BE BUILT "FROM SCRATCH".

Commercial kits may be used, as long as the SO building policy is followed: https://www.soinc.org/building_tools_policy

(Section: 4 / Paragraph: i / Sub-Paragraph: N/A / Line: 1)
11/07/2016
DO COMMERCIALLY AVAILABLE SWITCHES, SUCH AS DIMMER SWITCHES, COUNT AS INTEGRATED CIRCUITS?

It depends on the specific switch. Some switches are purely mechanical (i.e. utilize a potentiometer) and are allowed. Others are digital (i.e. utilize an integrated circuit) and are not allowed.

(Section: 4 / Paragraph: j / Line: 1)
11/07/2016
FOR THE DEFINITION OF A "CUSHION OF AIR": DOES THE AIR HAVE TO HAVE A WAY OUT OF THE CUSHION ON THE BOTTOM OR SIDES, OR CAN IT BE DESIGNED SIMILAR TO AN AIR MATTRESS?

Yes because it is not hovering unless air is coming out. The air must have some way of escaping (i.e. it should need to be actively replenished for the device to work, not just be a sealed inflatable chamber).

(Section: 4 / Paragraph: j / Line: 4)
11/07/2016
HOW HIGH MUST THE HOVERCRAFT HOVER?

There is no set distance it must hover. If an event supervisor, from a normal observation point without having to get up and close to the hovercraft, can visually see it move down when pushed, then yes it levitates.

(Section: 2, 3 / Paragraph: 5, 6 / Sub-Paragraph: f, b / Line: 1,1)
11/07/2016
IN SECTION 2, PARAGRAPH 5, SUB PARAGRAPH F, THE RULES MENTION A TARGET TIME AND THEN IDENTIFY IT FOR C ONLY. IN SECTION 3, PARAGRAPH 6, SUBPARAGRAPH B, THE SCORING SAYS THE TIME SCORE GIVES A CALCULATION INVOLVING A TARGET TIME. PLEASE CLARIFY.

5.f. doesn't identify the target time for C only. It only mentions that the target length will be announced for Div. C only (since Div. B already knows the target length). The target time concept applies to both B and C. The reference to Div C is for the variable length that must be announced.

(Section: 4 / Paragraph: i / Line: 1)
11/07/2016
IS A BREADBOARD WITH RESISTORS AND/OR TRANSFORMERS CONSIDERED AND INTEGRATED CIRCUIT?

No. A breadboard with discrete resistors and/or basic transformers is not an integrated circuit. Note though that some types of resistors and transformers ARE integrated circuits and hence are not allowed.

(Section: 4 / Paragraph: i / Line: 1)
11/07/2016
IS AN ARDUINO AN INTEGRATED CIRCUIT?

Yes, an Arduino contains many integrated circuits and is not legal.

(Section: 4 / Paragraph: b / Line: 1-2)
11/07/2016
IS THE MAXIMUM DIMENSIONS OF THE SKIRT 19.5 X 30 CM WHEN THE HOVERCRAFT IS INFLATED OR DEFLATED? CAN THE SKIRT BE LARGER THAN THOSE DIMENSIONS WHEN THE MOTOR IS NOT RUNNING?

The maximum dimension of the skirt is the same as the device, 19.5 cm wide x 30 cm long, both inflated and deflated. Students may tuck the uninflated skirt under the device prior to inflation.

(Section: 4 / Paragraph: h / Line: 1)
11/07/2016
IS THE TOTAL VOLTAGE FOR THE HOVERCRAFT 9V, OR IS 9 VOLTS THE MAXIMUM RATED FOR EACH CIRCUIT? FOR EXAMPLE, MAY I HAVE A SEPARATE 9V BATTERY FOR EACH MOTOR IF THEY ARE NOT LINKED?

Yes, multiple batteries may be used as long as they are not connected in such a way that the voltage exceeds 9 V in any circuit. Separate 9 V circuits are allowed.

(Section: 5 / Paragraph: f / Sub-Paragraph: N/A / Line: 1)
11/07/2016
IS THERE AN INTERVAL FOR THE TARGET TIME OF THE COMPETITION. EX-- BETWEEN 5.0-25.0S IN INTERVALS OF 1 SECOND

No

(Section: 4 / Paragraph: e / Line: 1)
11/07/2016
PLEASE DEFINE WHAT THE PROPELLER SHIELDING IS (1/4 IN DIAMETER?).

The propeller(s) must be enclosed in such a way that there are no holes bigger than 1/4" in diameter in the enclosure. A 1/4" dowel rod must not be able to penetrate the material.
(Section: 4 / Paragraph: g / Line: 1)
11/14/2016
THE 1/4" OR LARGER DOWEL. CAN ANY MATERIAL BE USED (I.E. WOOD, PLASTIC, METAL), AND MUST IT BE SOLID OR CAN IT BE AN OPTICALLY OPAQUE TUBE MEETING THE SPECIFIED DIMENSIONS AND PURPOSE OF BREAKING A LIGHT BEAM?

The dowel can be any material, but by definition a dowel is a solid cylindrical rod, hence a straw is not allowed.

(Section: 4 / Paragraph: i / Line: 1)
11/07/2016
THE CLARIFICATION ON THIS RULE IS NOT ENTIRELY CLEAR. IF I FOUND A COMMERCIALLY-AVAILABLE PRODUCT CONTAINING A BRUSHLESS MOTOR ATTACHED TO A FAN, MUST IT BE LABELED AS A "COOLING FAN" TO BE LEGAL?

No. As long as it is a fan typically used for cooling electronics or computers it does not need to be labeled as such.

(Section: Constr / Paragraph: i / Line: 1)
11/07/2016
THE RULES SAY THAT BRUSHLESS MOTORS AND INTEGRATED CIRCUITS ARE NOT PERMITTED, DOES THIS JUST REFER TO INTEGRATED CIRCUITS TO CONTROL MOTORS OR THINGS LIKE ADJUSTABLE VOLTAGE REGULATORS AND ARDUINOS.

Note there is an official rules clarification related to this, available at: https://www.soinc.org/official_rules_clarif The integrated circuit prohibition refers to all components (including voltage regulators / arduinos) other than those specified in the rules clarification.

(Section: 4 / Paragraph: i / Sub-Paragraph: n/a / Line: 1)
11/07/2016
WHAT CONSTITUTES AN INTEGRATED CIRCUIT?(IE. ARE RESISTORS, CAPACITORS, TRANSISTORS ALLOWED? OPERATIONAL AMPLIFIERS?)

An integrated circuit is a circuit in which all or some of the circuit elements are inseparably associated and electrically interconnected so that it is considered to be indivisible for the purposes of construction and commerce. Most resistors and capacitors are not integrated circuits. Nearly all transistors and op-amps are integrated circuits.


Microbe Mission

see the new list of Microbial Diseases: The Life Science committee has limited Potato Blight to Early Potato Blight and will accept the terms Ebola and Chlamydia. (21-Nov-2016)


Towers

(Section: 5 / Paragraph: b / Sub-Paragraph: v / Line: 1)
12/01/2016
FOR THE LOAD SCORED BONUS, THE TOWER MUST BE CLEAR OF THE 29.0 CM DIAMETER CIRCLE. IS THIS DURING SETUP ONLY OR ALSO DURING LOADING (PRIOR TO TOWER FAILURE)?

The Load Scored Bonus is awarded only if the tower is outside of the 29.0 cm diameter circle through the entire testing. If the tower sags inside of the 29.0 cm circle during testing but the bucket remains off the ground and the tower is still outside the 20.0 x 20.0 cm opening on the Test Base, testing will continue until failure occurs as defined in the rules.
