Your latest scrounge/acquirement

I tried sending it home, I think someone else was controlling it though and it kept crashing into stuff... it's practically dead in your kitchen atm, near the table

I was driving for a bit. Ya, sending it home just makes it crash into chairs.

I did get a good shot of the dog eating a treat.

You need to add screenshot support, and it saves the shots to an SD card or something

My last "scrounge" over the weekend (though I paid for the stuff) at Apache Reclamation and Goodwill:

ARE: A garmin streetpilot III for $20.00, plus some miscellaneous low-ohm power resistors for current measurement.

Goodwill: A "matched" (same model) pair of Ryobi 7.2VDC cordless drills (for the motors and gearboxes) - $5.00

In the true "scrounge" department, I'm thinking about tearing apart an old Hoover steamvac (probably the only thing worthwhile there is the motor); our's died a while back, and my wife bought a new one (a Bissell this time 'round - seems to do a great job). Not sure if I'm really going to or not - might just donate it to Goodwill for others...

If you click the camera, it will open a still-frame photo (jpg) in your browser (this is based on IE and/or Firefox)

Battery did die.. it's back on the base now charging (but since it's on the base it will be working again, just not able to do much driving until the batteries charge up, seems to take at least an hour or so with that AA's)

Were you able to get audio?

Additionally, it looks like the sucker was out and about with you guys for almost 45 minutes before it died.. much better than I thought it would do, especially since it was doing substantial movement and not just video.

Going to have to start a "Pimp My Rovio" thread :slight_smile:

OK guys don't make me regret this:

That's the Rovio. Take her for a drive... maybe 30 mins of battery at best...

I drove it off the dock then realised I had better things to do.

Very cool though...

So yeah - that was me then :smiley:

Don't solder me bro! :smiley:

sure it's silly but it's also fun :wink:

Yes very fun.

I thought I heard some noise every now and then, but by the time I first logged on it was low

On Saturday I scored 6 metres of UPVC fascia panel for nothing. This is for a Dr who Prop See image -

This may become relevant if I manage to get my head around programming my Arduino to make the prop 'function'.

This will consist of counting from 8 - 0 rounds, detecting that the magazine then has been changed to begin again. Also each shot requires the gun to be 'cocked' using the pump action. Sound and muzzle flash will also be a part of the effect.

In theory Arduino will make this simple, in terms of component count and simplicity and allow for a realistic operation of the 'BFG'.

I have a circuit drawn up that uses 3 555 chips and 2 chips to drive a 7 segment display which will work fine. At this time this circuit has the upper hand......On the Arduino I can make the LED blink, several LED's blink but so far Mr Lightbulb hasn't gone 'DING'

Hey I am sorry. All I was trying to do is to walk around and go home. Did it get back home? (2:45pm Central time)? =( :sweat_smile:

Oh, now it back at the station.

Sounds like this is getting a bit off topic - perhaps a new thread :slight_smile:

Looking at a VCR - should I scrounge it?

Any fun in VCR's? Had a few laying around, threw them out... Opened them, saw a flat boring print, some custom motors and gears... boooooooooring... :grin:

Aren't the bearings on the heads really nice?

Yea, I've heard a couple times that VCRs have a few nice things in them

I may have just attacked your dog, and you. Maybe, not saying anything for sure...
:slight_smile:

Sorry!

That was entertaining.

If you really want to go crazy, go to your local photocopier repair shop!
Switches, LED's, LCD's, motors (stepper and DC), optics, driver transistors and best of all...
bearings, gears, shafts, ladder chain and sprockets!

Where I used to live the guy who owned to store said "yeah, go for it, just don't make a mess."

I reduced 20 photo copiers to bare chassis in a couple of hours!

I have discovered that a multi-thousand dollar (?) video conferencing camera system contains several rather neat motors probably worth $10 each or more. The best was a DC gear motor used to move a shutter in front of the camera (why? There was a glass panel in front of that... Just cool factor, or may so you know that you can't be seen when it's shut?) Pan and tilt accomplished by small geared stepper motors. Autofocus and zoom internal to the lens itself are very tiny steppers with very tiny ball screws.

It looked like there was a neat MEMS microphone array (6 mics?) and some nice stepper drivers as well, but in such tiny packages that I didn't feel they were removable from the PCBs. Sigh. In general, I find this sort of "reduction in value" from a working product to reusable parts sorta depressing. But I guess that's looking at it backward; better a few cheap parts than a pile of nameless eWaste. (and the stuff we throw out had better remain nameless and not intact as well. Recycling is good, and scrounging is probably permissible, but having your trash show up on the user market would be a pretty substantial scandal!)

I think you are looking at it wrong; its like looking at wrecked or junked/rusting automobiles, and thinking they're nothing but a bunch of scrap metal.

Meanwhile, tons of pick-ur-part places make a lot of money off those same vehicles (and whatever is left gets sent to a recycler scrap yard).

Generally - marketed properly - you can take "junk", take it apart, sort the parts and such, get enough of them and sell them as used components for hobbyists, if you wanted to. You might get something for free, or buy something at goodwill or a yard sale (for a few dollars) - tear it down, sort the parts, package them up, and sell them to others (who either don't or can't do what you did). You could, in theory, turn a $5.00 "junk" device into $10.00 of parts.

Here's a "for instance" - priced the Senscomp ultrasonic kits?:

http://www.senscomp.com/products.htm

Kinda expensive, huh? But they're pretty nice kits - in some ways better than the PING-type sensors, but not in price.

But there's a cheaper alternative, if your willing to do the work to remove it - from a Polaroid camera (Sun 660, Spectra, plus some others). You can find these all the time at yard sales and goodwills, generally for less than $10.00 (most of the ones I've found have been for $5.00 or less).

I bet - if you removed such a sensor from the camera - and set it up to be controlled by the Arduino (few parts are needed for this; it was detailed in Servo magazine not too long back by the member of SRS who originally showed how to use such devices with a PC parallel port) - with testing, packaging, marketing, and maybe some code - you could probably sell them for somewhat more than the PING-style sensor, but waaay less than the Senscomp kit, and easily make a healthy profit, while providing a useful device for hobbyists (or students, or educators) at a more affordable price.
