Let's Make Robots!

Happy Birthday, LED!

Today (October 9) in 1963, Nick Holonyak, Jr. demonstrated the first visible-spectrum light-emitting diode to the bean-counters at General Electric.  He mixed Galium and Arsenide in a way that chemists told him was impossible to create that first familiar red glow.  Today, we're on the verge of replacing all innefficient filament-based lights with his invention (if the conspiracy theorists don't get their way, that is.)

I am not sure if it's a good idea to replace ALL light bulbs with LED's.

My solar runner is not working with LED light :-(

So, I am not supporting a 100% exchange ;-)

I'm diabetic - I want a cake substitute :)

Ok, just to be clear...Please select one or more of the following:

1. There damn sure will be cake

2. There could be cake but it would be difficult

3. There is only a slim possibility for cake

4. It is highly unlikely that there will be cake

5. A cake might be available if its made for a 3D printer, and sent to all who have one

6.A conspiracy has evolved, and all cake is is banned and unavailable

7. Only a select few can ever have any available cake

8.A robot that makes cake and travels to each members house is being worked on, and likely will make me a cake soon.

9. I am just wasting my time thinking about cake, and therefore have NO chance of getting cake.......ever.

10. Cake is over-rated, and while I still want some, I should feel secure that I have seen my last cake for the forseable future.

11. The red L.E.D.s and his friends all showed up early and ate the cake, to create this cake shortage.(wait...Now there is a cake shortage?)

12. The word cake should never be mentioned in a place where I may see it.

13. I have a dream......I have been to the mountaintop.....and there is cake..........for all mankind.......as much as you want.......

14. The cake is IN the mail.

15.Flour, a major ingredient in cake has been deemed hazardous, therefore will never be used in cooking again, anywhere.

16. Cake baking is a hugh energy drain, and therefore not "green", thus causes global warming.

17. If someone bakes me a cake......I will come for it, as long as I know for sure it will really be there.

18. How can a semi-conducting light source, invented way back when, get cake, and yet I get none?

19. The droid carrying the cake IS the droid I am looking for........

20. Cupcakes are in fact an acceptable subsitute for most cake.

Thank you for your attention in this matter.

>20. Cupcakes are in fact an acceptable subsitute for most cake.

At a recent kid's birthday party, they served 24 cup cakes all served together on a platter with frosting over the top of the whole thing so it looked like a birthday cake from above. They did the whole candles and happy birthday song thing, then simply separated the cupcakes and gave them to the kids on paper plates. 

I just thought you'd want to know of the existance of such a thing, androidman.

I knew this would get your attention!

Incidentally, if you have access to a "Costco," I would highly recommend their cake for your next event.  It has to be the worst thing in the world for you as good as it tastes.

I haven't heard anything other than some trying to say leds are as toxic to the environment as cfl's. Is that the one?

Happy Birthday Mr Led!
