Make sure you've got a spare battery when you come to show it.
You dont want to be let down by something silly.

Yes attach the resistor to make it go.
Shine the light to make it stop.

I hope it works alright,
we havent had it stop yet from the laser ...

I think this laser is weak (it's "shine" is dimmer than before). I'm going to try another one. I chose the 47k resistor by the way. The laser was able to muffle the sound only slightly. I'll try it fast.

 

It works with my doesn't-get-dim-2-days-after-I-buy-it laser!

 

You're awesome, John! I love you (in a respectable way)!

 

Yeah, I'm definitely going to be bringing spare parts on presentation day. For now, I'll draw the schematic, analyze how everything is working, and confirm with you tomorrow (if you'd like).

 

Thanks a bunch! And I'm deeply sorry for keeping you up so so late. Hopefully, in the future, I'll be able to help you. Haha fat chance but I'll try.

 

Good job Anon and John! I had to run out to my wife's softball game. Looking forward to seeing the schematic and hearing how the presentation goes.


Torben

 

Thank you, Torben! Not only for the compliment but also for your help earlier! Yes, the presentation. That'll be something. I hope he doesn't try to burn me that bad. I'll have to prepare everything...in a power point presentation!

 

I'm just glad it worked.
Was starting to think that a single transistor would not do it.

Hope it goes ok, and i hope the tutor doesnt give you a hard time over it.

Thanks for your support Torben.
Goodnight all.
John

Yes, thanks once again, John!

 

Hey Anon,

I'll be online for a few hours yet if you have anything you want to work on before calling it a night.

PowerPoint? Argh. I feel your pain. Well, your presentation should certainly beat 2 balls in a sock.


Torben

 

Hey Torben, you must be awake for some time then if you got back from a softball game? I'll try drawing the general schematic of this thing (I'm not very good at drawing schematics--in fact I only started with my first post on here, unless I did some in grade 10 which I can't seem to recall...and I have no special program..I use paint) and show you. Of course, I'm not forcing you to stay awake like I practically did with John. But hopefully this schematic doesn't take too long.
