This Friday, federal appeals court in Washington D.C. decided that Federal Aviation Administration has no right to require hobbyists to register their camera drones and model aircraft. As SF Gate reports, this decision came after a drone hobbyist John Taylor filed a claim against the FAA in 2016. He claimed that they don’t have the right to force him to register his aircraft.As U.S. Circuit Judge Brett Kavanaugh states, “Taylor does not think that the FAA had the statutory authority to issue the registration rule and require him to register.” And according to the judge, he is right.Even with this decision, the restricted areas for flying unmanned aircraft remain the same. However, from now on, you can fly your camera drone or model aircraft in the permitted areas, but you are not required to register it with FAA as long as you use it for personal purposes.Drones used for crop or cell-tower inspection, real estate photography, as well as delivery drones, don’t fall into this category. They are considered commercial drones, and they still require registration.The registration system went into effect Dec. 21, 2015. From then on, as SF Gate reports, around 745,000 people have signed up with FAA. The new regulation (or better to say, the lack of one), could bring lots of issues.First of all, FAA uses the regulation system to educate users about safety. Also, when the owners register, FAA can track which of the users pose a risk. Without the registration, there is no way of tracing the drone back to the owner who poses the risk to others with irresponsible flying. For example, if someone hurts a person with a drone or flies in the restricted area, the authorities have no easy way of finding the pilot. Considering that the number of hobbyist drone users is rising, I wonder about the results this decision will give.What do you think? Does FAA have the right to require users to register, or not? Was this a good decision?[via SF Gate]

PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure.

Day 1 (March 5, 2015)

I could see quite clearly after getting out of the LazikPlus center, better than without glasses but not perfectly.

When I take my drops and sit down almost inevitably now the medicine runs into my sinuses and into my mouth and I get this nasty medicine before either but I have noticed that my sinuses are all clear so I’m assuming that if I had some sort of bacterial infection or anitbiotics would leak into my sinuses, they’re taken care of now.

Day 2

All hell breaking loose, my eyes are on fire. Lots of pain and I can’t really sleep or anything, wow this is bad. Used the numbing drops. Having a hard time not rubbing my eyes.

Day 3

Failed and rubbed the eyes at least once, feeling a lot better and seeing fair. Eyes mostly not hurting but they feel scratchy and the left one feels the worst.

Day 4

Vision still bad still @ about 20/40 or 20/50. They are feeling better and the “sand” feeling is moving around the left eye, the contact bandage may be moving around ???

Day 5

Vision a whole lot better, still a bit fuzzy, maybe due to the contact bandages. Feel much better.

Day 6

Back to work today, had trouble keeping my eye open and staring at the screen. Got some stuff done though.

Push-button on/off switch using complementary MOSFETs.It’s taken from the excellent book The Art of Electronics [2], and like the CMOS version it draws no current when the switch is off, because both MOSFETs are in a non-conducting state.As before, to drive more than 100mA replace the p-channel MOSFET at the output with a power one, such as the NDP6020.

I’ve been putting together a little robot pictured on the right for the last few months. Nothing fancy but I’ve played around and wanted to have a circuit to with a pushbutton to turn it off and on. Here is a few circuits that may fill the bill.
