The bad news is that this city has very few storefront outlets for electronics. If you need a last minute component, you’ve got three options, basically: Radio Shack (a few of them left around the city); The NYU Computer Store (across the street on Broadway); and 269 Electronics. AC Gears is a storefront around the corner from ITP that carries Arduinos, 3D printers, and the like. Save yourself time and call any of these and ask if they have what you need before you go.
You’ll end up buying most of your electronic components online, so plan shipping time into your project planning. Here are some of our regular sources:
Adafruit is based in NYC, delivers fast, and has many components and modules that work well for this class. A ground-based shipment from Adafruit will often arrive before a two-day shipment from other retailers. Their customer service on shipments is excellent, and their tutorials are quite good too.
Spark Fun has a wide range of components and modules to solve many common physical computing tech challenges. Based in Colorado, they’re also pretty fast on shipping, and good with the customer service.
Seeed Studio has some really interesting components. They ship large orders free from Shenzen, China, but shipping isn’t always fast that way. You can pay for expedited shipping though.
Solarbotics is good for motors and motor support components, but carries a range of other components as well.
There are many large distributors of bulk components like resistors, capacitors, transistors. They’re not aimed at the hobbyist market, and their sites can seem a bit daunting at first, but they’re very useful as you get to know how to shop. We use Digikey, Mouser, Jameco, and Newark frequently.
Bourns makes knobs and switches for guitars and other musical instruments.
Grand Brass makes lamp parts and has an excellent site for figuring out what parts are called.
McMaster-Carr supplies every piece of hardware you can imagine, and has a very good (and forgiving) search engine. They are in New Jersey, so stuff gets here fast when you order from them.
Prince Lumber carries wood in various forms. They’re located at 404 West 15th Street on the corner of 9th Avenue & 15th Street.
The Container Store carries a wide range of containers that can be useful as project enclosures, and they’re generally cheaper than buying electronics-specific enclosures. There are a few locations in New York. The closest is on 6th Ave near 18th St.
Canal Plastic carries plexiglas and acrylic in various forms. It’s fastest to go there in person. They are located at 345 Canal Street.
Canal Rubber carries a variety of rubber and neoprene stock items. They’re also on Canal St., 329 Canal St at Greene St.
There are also surplus houses that sell overstock and discontinued items. While they don’t always have the same thing in stock all the time, they’re excellent sources of discount deals and hard to find items. All Electronics, Electronics Goldmine, and Herbach and Rademan are examples of these.
Surplus Shed has everything. Really. From optics to electronics to chemistry tools, they have it.
