Hi guys i do ebay for a living bc sadly my husband works as a supervisor in construction and does not make enough money I doing ok on ebay but still can’t catch up on bills I want to expand this job and wnat to get into dropship ….. I have to find a distributor . Do you guys know of a good company and what this all abut . I like to sell clothing or women accessories, that is the only thing i am good at not electronics. I want to make more money on ebay other than my items please help and if you do the same give me some advice . I don’t want to struggle in life anymore and would like to take my children to Disney or so . I am so tired of working paycheck to paycheck please help Just a comment i feel mad everytime i see a celebrity buying a 200,00 jewlery or so when i would have to work 3 yrs to make that kind of income . Doesn’t that make you feel terrible??? I want to start making more money. I have plenty of energy and desire to make money!!

I suggest that you get an account with UPS or Fed X. Not only will they come to your house to p/u your freight they will bill you later. It is not that expensive. I have used them myself.

I have my S Corp established, my Tax ID, my resale license, etc. I am looking for a REAL distributor of consumer electronics such as Xbox360, Wii, Ipods, Plasma TV’s ,etc.

I have come across nothing but sites that say wholesale, but they are either selling non-name brand stuff are are simply charging retail.

Can anyone provide me with some contacts at real wholesale distribution companies, it would be greatly appreciated! Thanks!

Forget wholesale, you wont find it unless you buy straight from the manufacturer.

I get all my electronics from freebie sites ever since i saw that NBC report. There’s a link in my profile to them.

It’s for GCSE and I’ve built a simple pressure pad alarm but what can I add to it ? I’ve already got an oscillator, logic gates, some memory, a high pitched buzzer and push switches for inputs ( of course, 1 to act as the pressure pad and the other as the reset button for the owner of the house to press to reset the alarm).

Or rather, how can I incorporate a 7-segment screen into the circuit ? Or possibly an additional LED to light alongside the buzzer ?

Any ideas are kindly welcomed,
Dogguy.

One thing that distinguishes the real alarms from amateur ones is supervision. If the connecting wires are cut or shorted in real alarms the alarm will put out a trouble signal because it knows that the current level is not what it should be.

They also tend to have alarm silence circuits. If an alarm occurs a buzzer rings and a lamp lights. If you press a "silence" switch the buzzer goes off and the lamp blinks till a second button is pushed which Resets it.

THose are simple things to do with logic gates.

As far as 7 segment screens look up the drivers for them. Typically anytime you want to put numbers on that you need to use 7 outputs and store a table showing which segments are on and off for each number. Then you have to chip select one character and turn on all its "on" segments. Then go onto another character and do the same. That would let you indicate which switch has been tripped by the alarm.

I need a good site in which I can get electronic parts. LED lights and resistors ect. DO NOT say Radio Shack they don’t have the number or size of parts I need. (like a 10mm Led)

Digikey is great

I am using a two-resistor model for modeling an electronic component thermally. Do any of you know of a good worked example that I could use as a reference?

A germanium diode has a junction temperature not to exceed 100C. How many watts will this diode dissipate at the maximum junction temperature?

Given:
Thermal resistance junction to case Trjc = 0.7C/watt
Thermal resistance case to ambient Trca = 40C/watt
Maximum ambient temperature = 30C

Solution:
Tj – Ta = q x (Trjc + Trca)
100 – 30 = q x (0.7 + 40)
70C = 40.7C/watt x q(watts)
q = 100/40.7 = 1.7 watts

If you know q and want to calculate Tj

Tj – Ta = q x (Trjc + Trca)
Tj – 30 = 1.7 x (0.7 + 40)
Tj = 1.7 x (0.7 + 40) + 30
Tj = 99C (with a little rounding error)

Heatsink and semiconductor manufacturers may have other examples in their application information.

How common is having an electronic organizer among college students? I never noticed my friends having one though. However, I thought it will be helpful since I am always disorganized during school time. Another question, can you suggest good but affordable types of electronic organizers?

i’ve never seen anyone using an electronic organizer.. if they do use one, it’s probably using their blackberry or something like that.

don’t waste your money.. most schools give out planners with self-organizing tips anyway. if you really need one after the first semester, then get one.

I have an old Gameboy Advanced and a Gameboy SP. I was wondering if they have any precious metals in them. Is it only computers that have precious metals in them? I understand that trying to extract the precious metals out of electronics is dangerous, but I was just wondering.

almost all do.

microprocessors have gold wires, gold plated contacts, silver plated contacts, copper traces…

Here’s one of the reasons. A video walkthrough of one of our big local electronics surplus stores. This is the smaller of two such stores I know about (HSC, the bigger one is Weird Stuff). The video shows about half of the store. It’s a bit boring, even if you’re into this kind of stuff. It’s just meant to show how much cool junk you can find here.
