MythBusters - or - Is there too much heat in my Bubble
Now and then the conversation comes up about heat in the bubble and what we should be using now days for lights and how many. It always boils down to LED VS. Incandescent bulbs.
First, here's my set-up in the Bubble area - I have a total of 38 incandescent bulbs - 3 on the top, 28 inside the brain, and of course, the 7 finger lights.
Charlie had access to a laser temperature reading device. Pretty cool - whatever the laser was pointing at - it would read out the temperature of the surface.
The following chart gives you the time intervals that the temperatures were read and the actual readings. It is opinion of Charlie and I that incandescent bulbs are not a problem at all. The final choice is yours. All times are from the Base Line.

Time |
Brain Side |
Brain Top |
| Base line | 71.5 | 71.5 |
| + 10 minutes | 78.7 | 78.2 |
| + 30 minutes | 83.5 | |
| + 50 minutes | 83.6 | |
| + 75 minutes | 84.7 | |
| + 195 minutes | 97.4 | |
| + 144 minutes | 84.3 | 89.2 |
|
Note - at this time Charlie's brain read 71.2 on the brain side and 78 on the brain top |

| + 199 minutes | 83.6 | 90 |
| + 258 minutes | 84 | 91 |

So, we started our robots at 8:32 am and the last reading was done at 4:04 pm - The level of heat only raised 19.5 degrees in my bubble and the difference between the readings from Charlie's brain top and my was only 13 degrees. The top of my bubble felt slightly warm, but nothing close to being called hot. |

One other thing that I noticed when doing this test - I had placed the voltage regulator for the ear motors directly on the inside top of the radar section. The temperature there read 117.2 by the end of the day. I would recommend mounting the voltage regular in the radar section so that air can get around it - it prevent overheating of the radar section with a hot spot.
