Those buttons with the green lighting... Ive seen them before... I don't remember where... Where can I buy some?

Would this do? All the "Screw Conveyor" would be is a circular piece of sheet metal, with a radius cut out, and then bent out at a 45 degree angle. Do you think the food would even get pushed all the way to the "Screw Conveyor"?

>>752116
So horizontal wont get jammed as easily?

Would a piece like this do? Or does it need more spirals?

Thanks!

It will be dispensing at a specific time of day. There is also a chute.

>>751906
Precisely!

>>751892
Yes, but where the "blade" only makes one revolution around the Y axis.

I already have the PVC parts for a vertical construction. But I could see pellets getting stuck in your idea :/

>>746645
I do something similar. But instead of using solder to do the traces I use wire.

Hey guys,

I'm trying to automatically dispense pet food out of a 75mm (in diameter) PVC pipe. I have a continuous servo with torque of up to 13 kg.cm. Since I'm not a mechanical engineer, I can figure out which way is best to control the flow of food particles. I'm thinking either something like in the picture (but made out of welded sheet metal), or something like a 360 degree worm gear. I'm not sure which is most likely to get stuck, which requires less torque, and if there is a better design out there?

Thanks!

>So to continue, being pessimistic and assuming consumption increases to say 250mA with lower voltage, you'd need 1250mAh 3.7 pack for 5h runtime. Add something for inefficiencies, hiccups* and crappy batteries and you should look at 1500..2000mAh range.
How's this? http://hobbyking.com/hobbyking/store/__18560__Turnigy_5000mAh_1S_20C_Lipoly_Single_Cell_.html

So is that 4.5 on, or 4.5 recording?

>>727534
I have a multimeter, yes. I got my camera for $10 off ebay.

>>727527
The camera hasn't arrived in the mail just yet. But there is an image of the battery here: http://www.rcgroups.com/forums/showthread.php?t=1911062

It doesn't seem to have any markings. At least not on that side.

>>727523
It will be stuck into the ground or onto a wall.

>>727515
Size isn't too big of an issue.

>>727514
Thanks, is there any way of measuring Amp hours?

I need your help.

I want to mod the y3000 so that I can use a longer lasting battery (hopefully 5h). How can I figure out what specifications I need on the new battery? What matters? Current?

Thank you.

Camera is the one in the pic.

I may be wrong but if you have the ported subs under the desk like that, the port will blow annoying puffs of air onto your knees in time with the music.

Just a thought

Hey /diy/ I recently realized that I spend to much time sitting at my computer and I thought that maybe I could get some exercise worked into my day with a homemade bike generator.

I'm not all that good at this kind of thing so I was wondering if anyone has some schematics or simple guides of building a bike powered generator capable of running a laptop. (Id really need a step by step walk through of how to do this) Or if anyone has some helpful tips or tricks.

yea. just because its the most easily recognizable. my boss wants everyone do dress up for Halloween and he wants it alice in wonderland themed so idk.

for a guy btw

hey guys i was hoping someone could suggest a cheap way for me to make a cheshire cat costume. (the cat from alice in wonderland)

Yeah Exactly... I don' know, I'm kind of frustrated at how little people care and how the "system" actually doesn't work all that well :/

and yeah basically what i said the thing with I should know for an emergency or something but th' just said it's in my records

+ Tried asking... they told me "what makes you want to know" and they didn't want to tell me o_O
I just trust myself more, so many rules and regulations in todays society :/
