On-line electronics store up and running

After a few false starts, my on-line store is running! I have absolutely no experience setting up a website but it is coming along quite well. Over the next couple weeks I will be adding over 2000 items to my catalog and actually added about a hundred today.

Comments & suggestions are welcome.

On-line store up and running!

I just published my first website: www.salvage-1.com and it should be live any minute now.

I will be adding items on a daily basis as I have over 2000 part numbers currently in stock as well as all types of unique and interesting items.

There will be certain core items, (like the soldering stations), that I will always sell but other items, (due to the nature of the surplus business), will be limited quanity. What that means is, when they're gone, they may be gone for good. I buy at auction every other Saturday so there will be new and different items added continously.

Parts for products?

I plan on making various robotics kits for beginners. My first kit will include parts for a beam robot, is it ok if I buy parts online from ebay or other sites and resell them as a kit with instructions?

Ebay mixed bag of robot bits

I mentioned on SPANR's page that I bought a bunch of robot bits on ebay some time ago and I started playing with them recently. This blog is my way of keeping track of what I got and some thoughts on what I can do with it.

First off, the biped.

where can i find these vex pieces?

okay, I have been scouring google trying to find the parts for the vex rcr mini walker crab thing, which should be displayed.

all the results I have found have been things like press announcements and demo robots built witgh this stuff, and none of it recent.

I personally want to build that walker, obviously with some extra personal touches added on, but I just cannot find the parts. every place seems to indicate that they were released, so did I just miss a limited run component or something?

 

 

Old Laptop Parts

I have an old non-functioning laptop, well its not that old sad to say :( only 2 years old. but was goin to start my first robo soon and was wondering if i there were some parts on there worth salvaging on there......ie:webcam, wifi radio, female USB's on mobo, etc.....

thanks for any and all help provided!!!

Small Parts Store Canada

Hey guys,

Does anyone know of a good small hardware store that is in Canada/will ship to Canada and not charge an arm and a leg for shipping?

I am trying to find something like this;http://www.smallparts.com/

Sadly this place charges an import fee and shipping that makes buying unreasonable for us Canadians.

Cheers,

My parts

Yes! My parts arrived today and now i got them.

There are over 400 parts in this box (not include picaxe things):

There are ldrs,resistors,electric capacitors,ceramic capasitors,motor driver,08M,transistors,leds,axle,wires and lots of other things what i can use on robots. But still i have to order more parts, motors,breadboard and battery holders.

Good Stuff to scavenge from a cell phone

I just ripped apart an old Samsung SGH-T739.

Picture of Samsung t739

I was planning on using the vibration motor that is used for silent mode. As long as I have this thing torn apart, I'm curious about your ideas for what else might be good to use.

Really cheap parts?

Hello people of the world :)

Sorry I having been posting any robots so far, but for now I need your help again :)

Infrared Receiver

I've found heaps of places that sell IR emitter LEDs, like these ones: http://littlebirdelectronics.com/products/infrared-led-950nm-1pcs

But I can't seem to find any IR receiver LEDs, like the black ones used by many in their distance or motion sensors.

Can anyone point me to a place selling them, preferably in Australia?

Small nuts and bolts, where do you get them?

I asked this question once before in a bad spot I think. Where do you all get small nuts and bolts. I went to a local hardware store for really small nuts and bolts, like 2x20mm, 2x12 mm, and similar sized imperial nuts and bolts. I walked out of the place with like 30 bolts and 30 nuts and it was over $30.00!!! I used all of them on one project and still have to go get more. But at 45 cents plus a bolt, it is gonna bankrupt me. Is there a good place online to buy these things in like 100 packs or boxes or something for cheaper than a dollar for one nut and one bolt?

Scavenging

I dissasembled my broken TV and got alot of random stuff. Is there anything useful there? I found a diode and a IR reciever and alot of buttons and caps and resistors, and alot of stuff i cant identify yet, i will post pictures of it when i dissasemble it... What special parts should i look for? =D

 

Does anyone else break stuff to get parts from it?

Tayda?

Hi,

Anyone have experience (good or bad) with Tayda electronics? Please share.

I just googled this one part and Tayda came up as the absolute winner on price. Who would like to teach me how to order small quantities from suppliers far far away. Any caveats, consumer traps, unusual conditions, broken promises?

SF order on it's way[shipped!]

Since it's been a while since anyone has posted on this forum, just thought I'd post something.

Finally put my order in thats been in the cart on that fateful freeday. added a couple extra things to it as well since I have a mini project going.

Opted to get the polulu trex motor driver as well since my hbridge attempt has yet to work(though I haven't tried to trouble shoot it for a while) .

Got a couple of 20x2's to see what they are like and since they had some sweet hw access. Grabbed a couple of atmel 2313's since they have built in uarts.  

Shops for Aussies and Kiwis

Hey everybody out there in Australia. There are many shops out there that you can go to.

- www.robotgear.com.au (theres picaxe + arduino + some solarbotics + heaps of polulu + tank tracks +gearmotors +chassis and other totaly AWSOME stuff) and if you need other stuff, email them and u get them in like a month.

Fingertech Robotics Question

Do you remember when you sent me that hard copy pdf file of the high torque servo? With all the stuff I needed to Cad it? I need a hard copy of the servo horns it comes with. Please email it to Benbo231@gmail.com as you did before. Hurry, I am at a standstill until I get it, and my deadline is rapidly approaching! I have until the end of next week to CAD about 40 parts, usingabout 3 square feet of aluminum. Please hurry.

How far can you get in parts hunt?

Just an hour ago I have disjointed this little peaceful innocent birdy, just for a little switch as I ran out of them and did not want to stop my robot building proccess! I'm a feelingless monster...

The question of the day:

How far did you ever get in robot building fever? What dirty deeds you did and what sacrifices you put on altar of robot building?

:D

Basic progress

Here are a map of parts in the Mr. Basic kit

Mr.Basic manual page 3
So far I've dicharded:
The wheels (13&14)
The bumper (17)
The battery holder (18)
The front axle shift metal fixer (20)

and I've mutilated/hacksawed/drilled:
an Axis joint device (5)
both Front axles(7)
The Chasis (11)
one Decelerated pinion chassis (12)

And I know some of the copper tubes (22&23&24) have a dark future ahead dating my trusted hacksaw.

My remote control car met the end of its life last week. (smashed into a wall...) So, i salvaged everything i could, and found some interesting stuff:

A Motor Controller

Transmitter/Reciever (can control 2 servos)

5 batteries, ranging from 1500 to 2000 mAh

I also had lying around:

2 radio transmitters

a second switch for the motor controller

 

I need:

-arduino proto shield

-lots and lots and lots of polymorph. like a shoebox full. a shoebox from someone with canoes for feet.

Swapshop-Blog Version

Ok, so ive made a robot, still workin on it. However, im lookin to the next one already, and for it, i need an arduino. Im dead broke, but i saw Swapshop in the forums, and thought it was smart! however, the most recent post was like 2 weeks ago, and i'm lookin for more traffic then that.

Nicd Battery pack (1800 MaH)

2 Tamiya Gearboxes and Wheels

2 Leaf-Spring Switches

2 Radio-Transmitter like parts

Salvaging Parts

Hi all, 

I'm new here and wanted to know What would be good appliances or computer parts to salvage robot related parts? (motors, gears, electronics)

I saw someone take the HDD's motor, but it seems the use of it is a bit complicated, and I'm a complete noob.
Are all the motors in HDD's like the one he used or does it vary?
Thanks in advance,
AmunRa.
