Picture of Top / Best DIY Electronic Stores & Suppliers
Over the last few years I have ordered countless items online for various electronics and DIY projects. Ordering stuff can be a pain - tedious, frustrating, and often, overly expensive. This is the first Instructable you should read before beginning any electronics-centric project!

Each step has specific details about the stores. 

These are just my opinions based on my experience. This is in no way definitive. I encourage you to leave comments about each store based on your experience so we can build a stronger evaluation. I can potentially add more stores upon request - I know I left many out. 


ELECTRONICS


MECHANICAL, MATERIALS & MANUFACTURING


This list is (as you can probably tell) North America specific.

Seeed's link doesn't work.. do you mean their OPL?

http://www.seeedstudio.com/depot/OPLopen-parts-lib... i think they define OPL as a list of commonly-used components. the good things of opl is cost effective and Seeed allows you to purchase in small qty. But the selection i have to say is not enough...

add also this good resource website for electronic components : www.brooks-maldini.net

Great list! I'd like to comment on Solarbotics.

I enjoy ordering from them. The selection isn't huge, and some items can be overpriced, but I've found that comparing them to other distributors such as robotshop.ca and sparkfun.com yield similar prices. You can even find some of the same products as on bigger websites (such as sparkfun stepper drivers, a number of Adafruit products, etc).

If you're in the Calgary, AB area ( like I am) I'd recommend same-day pickup! Orders placed before 2:00pm can be picked up after 4:00pm. There's no storefront, but they have a reception desk, and welcome pick-ups. For me, this is perfect if I'm in need of a part and I don't want to wait or pay extra for shipping. There's no additional cost for pick-up, besides a $5 handling fee (which is removed if you spend $30 or more).

The staff is kind and helpful, and seem to have a good knowledge of the products they sell. I've spent hundreds there in $30 orders, because I prefer their service to most others.

I hope this is helpful!

Yo thanx for compiling this. I often use allelectronics, futurlec and jameco. Another one you might be into is tubesandmore.com

Hello, you may consider adding: http://voltatek.com

No physical store, only webstore. This is a new webstore.

They are in Quebec, Canada

Thank you for this instructable! Lots of very good info here. One thing I hope you could add would be what companies have a minimum purchase amount or a minimum shipping amount. A few times I have wanted to buy a just a dollar or two worth of parts but once I made it to the checkout the site would bump it up to their ~$20 minimum.
Thank you!
Fuzzy-Wobble (author)  liam23172 years ago

Sorry this list is not going to cover the European stores. I just don't know enough about the DIY scene in Europe, nor the hundreds of stores that support it.
I realize that, that is why I mentioned the 2 european ones

Interesting. I checked taydaelectronics who are actually in bangkok and they seem to be able to ship something for $0.99 whereas a company in my own country charges Euro 2.50
Fuzzy-Wobble (author)  diy_bloke2 years ago
That is interesting...

To the Newark/Element14 family, for UK/Europe you can add "Farnell In One" and "CPC"

http://uk.farnell.com/
http://cpc.farnell.com/

Also in the UK Rapid Electronics http://www.rapidonline.com/ -- I've dealt with them over the years, no problems.

Good Job. Here's a good handful more, some I have ordered from, the rest I plan to order from them.

http://www.alltronics.com/ - all kinds of stuff, low prices. Some new stuff, some surplus; decent grab bags.
http://www.taydaelectronics.com/ - Chinese component supplier. VERY cheap prices on some items. I haven't ordered from them but I have heard they do OK.
http://www.jameco.com/ - decent prices, good selection, always find something of interest
http://dx.com/ - similar to the Aliexpress site. Cheap chinese products, free shipping though
http://www.web-tronics.com/ - Generally has a few items you can't find elsewhere, OK prices
http://www.electronicsurplus.com - name says it all
http://www.surplussales.com - vintage parts, has all types of electrical surplus items, not just components
http://www.hosfelt.com/ - little bit of everything, has wholesale pricing
http://www.excesssolutions.com/ - various surplus items
http://www.wihatools.com/ - tools, tools, tools.
http://www.victornet.com/ - machinists tools and supplies
https://www.verical.com - similar to octopart
Nice writeup, I have used several of these companies myself. Another source to sometimes look at is ebay. I have bought many odd and older electronic parts off of ebay over the years.
Seeed: Instructions for kits compatible with Arduino and their own equivalent are somewhat nonspecific, probably because Arduino has so many different header arrangements. Other than that, though, their stuff is great quality, but not too forgiving for beginners- through-plated solder holes can't be desoldered with just an iron.
