Thoughts? (on rule points)
Posted: September 26th, 2009, 10:47 am
Bonjour,
I figured that I'd post some of the rule clarifications that we're sending in... and would like to hear what you think of them. While I realize that some of them are a stretch, I'd rather hear an answer then have to wander into planning without clarifications. I know that you guys can't make anything official, and we are sending them in, I was just wondering what your thoughts on these were. Note that I know that a lot of this isn't properly formatted for a clarification... and on a whole I think that some are definitely more critical then other clarifications, I also added comments below some of them.
1) As specified in the rules, points are granted for only whole seconds, is this true for point deductions, is it only a point off for a full second over(ie at regionals is 60.0 the same as 60.9)? Also for the second tie breaker, is this time measured only to full seconds? To then be broken by the third tie breaker? Or is it otherwise measured to the most accurate time measurement available?
2) Are Laser pointers that follow the specifications pointed out on the soinc.org website allowed on the device? More specifically are they one of the allowed electronics, and are they allowed to be powered?
Laser pointers and Lightbulbs are disallowed in section 3d, but lightbulbs are almost allowed in section 3g (see below clarification). They could be banned under the hazardous materials clause in 3e, but the soinc site says that they aren't hazardous if they are class II. Mainly, I like lasers...
3) Are lightbulbs allowed?
They aren't under the allowed list of electronics, unless you consider a light bulb a "resistor" but then why wouldn't a wire be a "resistor". It does later in the rules give flashlights a specific allowance of sorts (3g)... but flashlights are a combination of specialized resistors and gas, which could be considered a dangerous material.
4) Is the photocell specified in section 4b required to be the sole use of power for the motor? or can it otherwise act as a trigger?
I'm expecting that people will say that it has to be entirely powered, but it's worth a shot...
5) Are Light Dependent Resistors allowed to be used on the device, or are photocells limited to devices that produce a voltage?
I like LDR's (and they are cheap) but alas are not on the list of specified electronics, they would also be easier/cheaper to use then photocells for many of the same tasks
6)What are the specifications on "switches" are only certain types allowed, such as SPST, or limit switches?
The reason for this question is that technically some digital electronics might be considered switches (such as a schmitt trigger) but are clearly digital, while other mechanical implementations of a simple switch might not be allowed, because they are not "just switches" whatever that might mean. Personally I'm least worried about this one, but better to air on the side of being too safe then getting DQ'ed
