Discussion Overview

The discussion revolves around the justification for using six AA batteries to power a remote control for a toy helicopter that features two LED lights. Participants explore the implications of battery usage in relation to the toy's functionality, including potential transmitter requirements and the design choices made by the manufacturers.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether six AA batteries are excessive for powering two LED lights, suggesting it may be more about supporting battery sales.
  • Another participant proposes that the remote control likely includes a transmitter, which could explain the higher voltage requirement.
  • Some participants speculate that the LEDs might be infrared, used for communication with the helicopter, and question the necessity of a radio transmitter.
  • A later reply indicates that the helicopter recharges from the remote control, which may justify the battery configuration, although this was not initially considered.
  • Participants discuss testing methods to determine the nature of the remote control's functionality, including whether the LED lights up and testing the range of the remote.

Areas of Agreement / Disagreement

Participants express varying viewpoints on the necessity of the battery configuration, with some suggesting it is excessive while others propose it is justified due to the design of the toy. The discussion remains unresolved regarding the exact role of the batteries and the remote control's functionality.

Contextual Notes

Participants initially lacked clarity on the remote control's specifications and functionality, leading to assumptions that were later corrected upon reviewing the product details.

I recently bought a toy with a remote control. The remote control consists of 2 LED lights and is powered by SIX AA batteries. Am I being naive to think that 6 AA batteries is overkill for powering 2 LED lights? The toy itself is a propellor-driven helicopter that only weighs a few ounces and runs on 2 AAs. Is there any rationality in this other than supporting AA battery sales?

Presumably, the remote control also includes a transmitter...

I assumed the LEDs meant it was like a TV remote control, not a radio transmitter. Do you think it would have both?
 
Well yeah... an LED won't fly the mini helecopter, so it needs a transmitter (and it'll have a frequency written on it somewhere). The reason you you so many batteries is the voltage output, radio transmitters are typically 9V.

If you got 1 9volt battery that would do the trick, wouldn't last too long though. From that I suppose you could argue that it's keeping AA in sales. Just get rechargables.

This is a very simple helicopter that just goes up and down. It's meant for indoor use. I think the LEDs are just infrareds that flash codes to an "eye" on the helicopter. I have other LED flashlights that run on 2 AAs. I'm not 100% sure it doesn't have a radio transmitter but I don't see the point. Why wouldn't a TV-type infrared LED remote be sufficient?
 
Post a link to a similar type of helicopter please, without knowing what it is it's impossble to say. The pure fact it's 9V suggests a transmitter.

Although there are two very very easy ways to test this.

1.) Does the LED light up?
2.) Try using the helicopter with the 'remote' not in line of sight or anything that IR can bounce off.

Well, I haven't tried the thing out yet because I'm afraid of causing a global shortage of batteries if I do:)

Actually, I went and actually read the package (imagine that) and it says "infrared control," but the reason it has so many batteries, it seems, is that the helicopter re-charges from the remote control. Sorry I didn't realize and say this earlier. It invalidates this entire thread actually.

Apparently this toy is engineered quite cleverly to minimize vehicle weight. Praise to the engineers!
 
You read the product's specifications?! Blasphemy! :smile:

I know. I cheated. I should have just kept staring at the device and pondering the magic of it all.
