The type of fence you build for your animals will be most effective if you’ve first

The type of fence you build for your animals will be most effective if you’ve first considered the nature of your animals and the size of area to be fenced. The size and location of the enclosure determine the pressure the fence will receive from animals. Consider, too, the labor and skill available for installation. For many applications, electric fencing, in particular, offers flexibility of design and construction. Properly designed electric fencing can effectively restrain many types of animal – from bison to geese and rabbits. While not a good choice for deer and elk, electric fencing works well for pigs, cattle, and horses. With effective design and animal training, electric fencing can even work for sheep and goats. After animals are trained, electric fencing presents a psychological barrier rather than a physical one. While deciding whether the area to be fenced requires fixed materials or lends itself to electric construction, determine how the size and use of the enclosure will affect animal behavior. For instance, sheep grazing good pasture in a large acreage may be restrained by electric fencing because they behave differently from sheep confined in a small area wher...

Fire danger causes Nissan to recall over 450,000 vehicles

DETROIT (AP) — Nissan is recalling over 450,000 vehicles worldwide because a brake fluid leak could cause them to catch fire. Because of the fire risk, the company is urging owners to park the vehicles outdoors and away from structures if the antilock brake light comes on for more than 10 seconds. The recall, detailed in documents posted Friday by the U.S. government, covers the Nissan Murano SUV from 2015 through 2018, and Maxima sedans from 2016 through 2018. Also included are Infiniti QX60 and Nissan Pathfinder SUVs from 2017 through 2019. Most are in the U.S. and Canada. Nissan says an antilock brake actuator pump can leak fluid onto a circuit board, causing electrical shorts and fires. Documents filed with the National Highway Traffic Safety Administration didn’t say if there had been any fires or injuries in vehicles covered by the latest recall. A Nissan spokeswoman said she would look into the matter, and messages were left seeking details from NHTSA. It’s Nissan’s third recall for the same problem, and the company keeps expanding the number of affected models. About 120,000 U.S. vehicles were recalled in 2016, and Nissan issued a recall for 215,000 in 2018. A fire in a...

[Update: The final hours] Prime Day 2019 Mega-list: All the best tech, smart home, and phone deals (Updated continuously)

Prime “Day” and its 48 hours of sales are now upon us. Deals are coming and going almost faster than they can be mentioned, but we’ll do our best to keep this list up to date over the next two days. We’re still in the process of adding items to this list — we have a lot to go through and piles of coupons to test — but in the meantime here are many of the current Prime Day promotions. As always, our price comparisons are free of MSRP bloat whenever possible. With prices always changing, that sometimes means we’ll have to express our discounts as a range (i.e.,”$30-50 off” or “up to $40 off”), which might be a bit more work for us, but it works out to a better understanding of the real discount for you. Just because Amazon says “you save: $300″ doesn’t make it true. Many Prime Day deals will require that you be a Prime Member to snag them, so consider picking up a free 30-day trial if you aren’t. Other deals may have to be triggered via Alexa commands (sometimes Amazon does that) so consider installing the Alexa app. You can also get an extra discount by playing with the camera features on the Amazon app...

We’ll admit most of us are more comfortable with solder and software than mechanical things. However,

We’ll admit most of us are more comfortable with solder and software than mechanical things. However, between robots, 3D printers, and various other mechanical devices, we sometimes have to dig into springs, belleville washers, and linear actuators. Unless you are a mechanical engineer, you might not realize there’s a lot of nuances to something even as simple as a nut and bolt. How many threads do you need to engage? Do lock washers work? [Engineer Dog] has a post that answers these and many other questions. The top ten list starts off with something controversial: split ring lock washers don’t work. The original post cites a paper that claims they don’t except in very special circumstances. However, he updated the post later to say that some people disagree with his cited study. In the end, you’ll have to decide, but given there are other options, maybe we’ll start using those more often. Speaking of other lock washer options, have you ever seen a Nord-lock, a serrated flange nut, a castle nut, or a slotted nut? He also mentions chemical lockers and nylock nuts, which we have used before. How about a DTI smart bolt? The post also repeats a rumor we’ve heard before that Philli...

Growing up, my biggest secret was that I had epilepsy. I have had it since I

Growing up, my biggest secret was that I had epilepsy. I have had it since I was 5.  Neurologists kept saying, “She’ll grow out of it.” I’ve tried medication after medication, trying to control the seizures and limit the number of side effects.  I’ve tried weaning off medication, only for a seizure to return within one or two days. Life becomes more bearable when my seizures are controlled, but I never feel carefree.  Epilepsy is much more than having seizures. With my epilepsy comes fear.  I am constantly cautious and afraid.  I am afraid of having a seizure during school, at work or in public.  Although I’ve been seizure-free for over a year, I am afraid of driving down the road and feeling that tingling in my stomach and not being able to pull the car over quickly or safely enough. I am afraid of injuring my brain and body beyond repair. I am afraid of who will see me. I am afraid of waking up from a seizure and being alone. I am afraid of forgetting my medication. With my epilepsy comes depression. For me, epilepsy has always brought along depression for company. With each anti-seizure medication, the depression waxes and wanes, but it always lingers like a permanent reside...

A Complete Review of Semiconductor Lasers And a Few Words About What You Can Do With a 5.6 W Semiconductor Laser

This is a detailed article about popular inexpensive semiconductor lasers and about what you can engrave and cut using a 5.6 W semiconductor laser, installed on a 3D printer or CNC machine. The laser diode is a solid-state source of coherent radiation. In this case it is a solid crystal of aluminate gallium, a source of the laser beam with the wavelength of about 445 nm. The basic components of the laser are a laser diode, a cooling system and a power driver of the laser diode. The main trick in their production is how to make the driver as compact as possible and at the same time fail-proof, how to ensure sufficient cooling of the laser diode without the crystal degradation. That is, a laser, ready for operation, has not just an energy source but also a power driver and a cooling system. We are lucky in this, as diode lasers are rather small and light unlike huge CO2 and fiber lasers. It is easy to install a conventional diode laser on any 3D printer or CNC machine. Besides, the market offers a variety of DIY kits of the makeblock plotter XY 2.0 type, which are also suitable for laser installation.   Standard installation hardware is used for most of lasers, though sometimes on...
