Built my Anet 3D Printer on the weekend of Irma, started on Saturday evening and ending on Monday. Mostly.
Printed two things, the new fan nozzle and a part for the feather robot. Both seemed to have gaps and holes, googled that and got this info.
1. You are under extruding. Raise the extrusion multiplier by at least 5%.
2. Slow down print speed.
3. You have loose belts and excessive play in the printer (the A8 has tons of play it’s really junky but fun). If you don’t add a tensioner to the belts, it’s tough to keep them tight.
4. Raise the temperature to 230. The A8’s temperature probe is off on my unit.
I ended up ordering 2 3D printer kits from Gear Best, two ANET A8’s. I messed up and ordered them with EU plugs, I then sent a message to Customer Support to have it changed. Anet A8 Desktop 3D Printer Prusa i3 DIY Kit

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]
Georgia governor Nathan Deal has signed Senate Bill 85 into law, The state’s breweries will soon finally have the freedoms they have been so desperately seeking. The only downside? It doesn’t go into effect into September 1st.
SpaceX is targeting launch of NROL-76 from historic Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. Following scrub of the initial attempt due to a sensor issue, the two hour launch window now opens on Monday, May 1, at 7:00 a.m. EDT, or 11:00 UTC.
Following stage separation, Falcon 9’s first stage will attempt to land at SpaceX’s Landing Zone 1 (LZ-1) at Cape Canaveral Air Force Station, Florida.

Today is a sad day in photography world: after 80 years, Popular Photography magazine will no longer exist. Its sister magazine American Photo also closes after almost two years of being online-only. The upcoming March 2017/April 2017 will be their last issues, and they won’t even keep the websites alive. Starting from Friday, March 10th, […]
Push-button on/off switch using complementary MOSFETs.It’s taken from the excellent book The Art of Electronics , 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.
