Learn How to Use a Multimeter for All Your DIY Electronics Projects

Multimeters are a vital part of any electronics project, but learning how to use one isn’t as simple as it looks. Thankfully, the above video from Adafruit walks you through pretty much everything you need to know.

Adafruit’s video guides you through the basics of using a multimeter, including what those numbers on the display actually mean, how to pick the right voltage, and how to replace a fuse when you inevitably pick the wrong voltage and blow one. Even if you’ve been using a multimeter for ages, the video’s a simple and nice way to brush up on the basics.

Build This Wall-Mounted, Folding Workbench to Save Space In the Garage

Build This Wall-Mounted, Folding Workbench to Save Space In the Garage

If you’d like some room to spread out and work but your garage or basement doesn’t have a lot of room to spare, this wall-mounted, fold-out workbench may suit your needs. You’ll need the materials and tools, but this pegboard bench will give you room to work and store tools, and folds up nicely when you’re done.

While the draw of this particular workbench is that it folds up easily, and then folds down onto its legs when you need to work, but hidden inside is plenty of pegboard wall storage for tools, cables, and other things you might need when the bench is deployed, as it were. In addition to giving you a place to work, it also offers some helpful storage to keep your tools out of the way, even when it’s all folded up.

Instructables user WorkBoots09 put this bench together, and while you’ll definitely need some special tools and you’ll have to get the pegboard, plywood, and other hardware required, but once you have everything you need, even WorkBoots09 acknowledges that an amateur woodworker can make this project happen. Hit the link below for a full-walkthrough, complete with photos.

OSU investigating rival nSpireU for potential infringement

Ohio State University is not giving up on licensing or spinning out the software that spawned a rival startup after a first attempt at commercializing it broke down.
Earlier this week, I reported that Dublin-based nSpireU LLC intends to launch this spring with software written from scratch since November. Founder and CEO Jason Adams said his talks with the university had ended a month earlier.
University attorneys are investigating if nSpireU is using any of the university’s copyrighted code…

Dell’s $129 Dongle Puts Android On Any Screen With HDMI Input

cloud-wyseDell continues making bets on Android in its computing lineup with a new $129 device that brings Google’s mobile OS to any TV or display with HDMI input. The new stick runs Android Jelly Bean, also supports MHL connections (mobile high-def) and offers Bluetooth and mini USB for mouse, keyboard and other device connectivity. In addition to onboard connectivity for Bluetooth, the new Dell Wyse Cloud Connect also offers 802.11n dual-band Wi-Fi and the standard Google Play store for Android software. It’s an enterprise and business focused device, however, and also has Dell’s Wyse PocketCloud software preloaded to help it act as a virtual terminal for remote computers. This is, in effect, supposed to be the long-vaunted and sought-after thin client PC you can carry with you in your pocket that still manages to provide access to all your files, software and communications back home. Of course, that doesn’t mean it can’t also provide entertainment options to business travellers, since it’s capable of full HD output and should be able to easily run Netflix’s Android app. That “multi-core” Cortext-A9 ARM SoC might not be the most muscular mobile processor in the world, but Dell does specifically tout its HD and 3D graphics abilities in its specs sheet. It has 8GB of onboard storage, and 1GB of RAM, plus a micro SD slot that supports up to 72GB of additional space. Based solely on surface impressions, you could do far worse in a pocket computer for those gruelling weeks on the road if you’re a frequent business traveler. It’s interesting to see Dell move in this direction, effectively taking a page out of the playbook of devices like the Ouya and the Gamestick but cutting out all the nonsense and painting it with a business brush. Weirdly, more than anything else over the past half decade at least, this makes me want a Dell computer. Go figure.

Ten Items You Should Always Stock Up On

Ten Items You Should Always Stock Up On

Let’s face it: No one wakes up in the morning with a burning desire to buy everyday necessities like pet food, toilet paper, batteries, or diapers. And yet, when you’re out of them, your entire world can come to a screeching halt.

This post originally appeared on DealNews.

When you’re in a rush, a savvy shopper’s commitment to buying discounted goods goes out the window, and it’s easy to pay too much because you can’t wait around for a deal. Therefore, it’s cheaper and easier to stock up on these items when you don’t need them. We’ve rounded up a collection of items that you should always buy when you see a deal, even if you’re still fully stocked at home. Read on to see how you can save over $200 with a little advance planning.

Cleaning Supplies

Potential Savings: $10 on laundry detergent, $6 on dishwasher detergent

If cleaning supplies aren’t on your list of necessities, you either live in a dorm room or in a cave (and are apparently stealing WiFi from a nearby Starbucks). Still, even the average person probably doesn’t think about purchasing these household supplies until they run out. However, you’ll save an average of $10 on laundry detergent and $6 on dishwasher detergent if you buy in bulk ahead of time.

Paper Goods

Potential Savings: $9 on toilet paper, $27 on paper towels

Fact: There is never good time to run out of toilet paper. It’s all that separates us from the animals! Paper towels, conversely, may seem to be a less urgent purchase, but a minor kitchen spill can quickly turn into a Messapocalypse if you’re out of Bounty or Brawny. The only defense against a dearth of paper goods is proactive bulk-buying. In the last three months, we’ve seen an average savings of $9 on toilet paper multi-packs. Buying your paper towels in bulk is even better; you’ll save $27 on average.

Nonperishable Foods

Potential Savings: $12 on coffee pods, $10 on beef jerky

When you’re running low on funds, it helps to have a pantry stocked with sundry canned and boxed provisions. Nonperishable foods like breakfast cereals, coffee, ramen noodles, canned goods, and other such noms are all things that can be bought in bulk via Amazon’s Subscribe & Save program, which yields big savings. In fact, we’ve seen an average savings of $12 on Keurigs coffee pods and the like in recent months, and an average $10 off beef jerky snacks.

Pet Care Items

Potential Savings: $15 on pet food, $7 on treats

As a responsible pet owner, you know that Sir Fluffykins and Sgt. Barksalot have very basic needs, the ignoring of which will result in mad and/or sick pets. To save your furniture from claw marks and your slumber from hourly wake-up calls, your best bet is to stock up on pet supplies with coupons and rebates from stores like PetSmart and Petco; that way you can save an average of $15 on pet food and $7 on treats, which both Fido and our bank accounts have been happy about for the last three months.

LED Light Bulbs

Potential Savings: $9 on single bulbs, $30 on 4-packs

In the long run, LED light bulbs are extremely energy efficient and long lasting. However, the start-up cost of replacing every light in your home can be overwhelming. And unfortunately, waiting until a traditional light goes out to buy an LED bulb can mean missing a significant deal. We see a variety of deals on LED bulbs, sold singly or in multi-packs, and your savings will vary accordingly. If you just buy single LED bulbs when they go on sale, our research shows that you’ll save about $9 on average. However, if you grab a 4-pack on sale, you’ll net an average savings of about $30.

Office Supplies

Potential Savings: $16 on printer paper, $3 on ink, $8 on toner

An emergency office supplies purchase can send you into the red faster than you can say "I believe you have my stapler." Scoring office supplies when stores like Staples and Office Depot promote in-store coupons and rebates can yield big savings, like about $16 on printer paper. Of course, when you’re all out of cyan and your printer goes on strike, it’s best to already have some internet-bought generic ink on hand. (Brand-name ink and toner is considerably more expensive, so your best bet will always be generic.) In recent months, we’ve seen an average savings of $3 on ink cartridges, and an $8 savings on toner.

Batteries

Potential Savings: $11 on AA, $7 on AAA

If you’ve got a lot of small electronics (or at least one child) you know the extreme annoyance that running out of batteries can cause. By simply jumping on a battery deal every time you see one, you can save about $11 on AA batteries and $7 on AAAs. Interestingly, when you’re buying batteries, you won’t necessarily see the biggest savings if you spring for those super-jumbo-crazy bulk packages. The best battery deals we’ve seen in the past few months have been for packs of 4 to 20.

Baby Products

Potential Savings: $11 on diapers, $2 on wipes

Attention new parents: You will never, ever, have enough diapers. Newborns go through at least 10 or 12 per day. When added to the myriad of other baby products you’ll need to keep on hand at all times (like wipes, formula, breast milk storage bags, etc.), the costs can be daunting. Save yourself some future heartache and buy the bulk pack of Size 4 diapers that’s on sale now, even if your little one currently only weighs 6 lbs. In recent months, we’ve seen an average savings of $11 on disposable diapers and $2 on wipes.

Shaving Supplies

Potential Savings: $6 on razor cartridges

Running out of razor blades can, at first, feel liberating. After all ladies, no one can tell that you haven’t shaved your legs if you wear pants. And gentlemen, who doesn’t feel more dashing with a bit of stubble? But eventually, no matter your sex, you’ll either have to embrace your new life as Sasquatch or break down and buy some grooming goods. If you stock up ahead of time, however, you can save an average of $6 on replacement razor cartridges.

Toiletries

Potential Savings: $2 on toothpaste, $5 on deodorant

You’ll end up making some, let’s say, creative decisions about personal hygiene when you’re out of toiletries like soap, toothpaste, deodorant, and shampoo. If you don’t want to smell like a Comic Con refugee, you’ll definitely want to jump on any toiletry sale you come across, even though these items are always fairly cheap. Our research shows you’ll save about $2 under what your local Walmart charges if you pickup your toothpaste online when it’s on sale. Furthermore, in recent months we’ve seen an average savings of $5 on bulk packs of deodorant.

Total Savings: $206

There’s no worse feeling than unexpectedly running out of the necessities, but looking out for big discounts ahead of time will keep you well-stocked, sane, and in the black. By our count, if you’d only purchased our examples when they went on sale at any time in the past three months, you could have saved over $200! Clearly, avoiding those need-driven, spur-of-the-moment purchases by planning (and purchasing) ahead of time is your best bet for a happier life.

Readers, did we miss anything? What items do you think are best bought ahead of time? Have you saved a boatload of money buying something before you needed it? Brag about it in the comments below!
