rctimer.com is gone

Hi, A week ago I placed an order of over $300 on rctimer.com site, PayPal account was charged but I never got order confirmation from rctimer. Two days later, the site disappeared and emails are bouncing back. I know they sell on AliExpress as well, be very careful.

MMC UAV is to exhibit in Shenzhen CPSE 2019

The 17th China International Social Public Safety Expo (CPSE)will be held from October 28th-31 th,2019 in Shenzhen Convention & Exhibition Center, Shenzhen,  China. At that time, it will present the most advanced artificial intelligence, big data, and intelligent security products to the world. The largest scale in the exhibition This CPSE will be held at all exhibition halls of the Shenzhen Convention and Exhibition Center, The scale of this exhibition is the largest in history, with an exhibition covers an area of 30,000㎡, and hundreds of industry brand companies and more than 2,000 exhibitors participated in the exhibition. As a high-end brand event in China’s security industry and one of the important international security expo with global influence, the Shenzhen security expo will focus on showing smart city solutions, security prevention solutions, police equipment, emergency rescue, Bio-recognition, artificial intelligence machines, and other industries. This exhibition has attracted great attention among manufacturers, engineers, and distributors in many industries across the country. UAVs play an important role in security In the construction of smart security, UAVs play an important role. In the security scenes of military reconnaissance, emergency flood control, drought prevention, border surveillance, police monitoring, forest fire monitoring, and environmental monitoring, the drone acts as a “security weapon” for the reconnaissance unit. It can perform various tasks such as air surveillance, daily patrol, and rapid air attack. It can cooperate with the background command and control system, with the ability of situation sharing integration, collaborative planning and scheduling, remote command, and diversified intelligence processing. As one of the exhibitors

Cars vs robots

A scooter ran a red light at 25mph & smashed straight into it. Miraculously, only the wheel was smashed. He broadsided it & dragged it a few feet, but manely took out the food it was carrying. Scooters & bikes are in the grey area of not having red light rules enforced & not having speed limits. In regular use, the lion kingdom has had 1 wreck every 2 years & all in crosswalks or sidewalks. The 1st wreck was an SUV turning right, destroying the cargo area, damaging the chassis & 1 wheel.  Enough was left to keep it going for under $50, but a more permanent repair will eventually be $150. Ground vehicles which use the road network have similar expenses as flying, but instead of impacts with the ground, it’s impacts with full sized vehicles. Fortunately, they don’t damage the other vehicles or cause injuries, but when cars impact robots, car insurance doesn’t cover it & it’s pretty much the robot owner’s expense. They’re quick with the sorry’s & the excuses but no driver is willing to pay for it. Lions don’t pressure anyone for money because of what happened to quad copters. If there’s any hint of liability, they’ll regulate the ground robots into the stone ages. They’re already banned in almost as many areas as quad copters. The mane problem is they’re harder to see than humans. Near misses with cars happen every month, usually when cars make right turns. High acceleration & planning for

Hackhawk Mark III: ESP32 TinyPICO as a brushless flight controller

My hacked Altair Aerial Blackhawk continues to serve as a great test platform for experiments in DIY flight controllers. So, when I heard the buzz surrounding the ESP32 line of Arduino-compatible microcontrollers (Dual 240 MHz cores, WiFi/Bluetooth on-chip), I knew I had to try one of these boards on the “Hackhawk”.   If you’ve been following the developments in the ESP32 community, you know that the smallest ESP32 board is the recently-released TinyPICO.  With its petite form factor, this board seemed to me like an obvious choice for indoor MAVs, and I wasn’t disappointed.  This wiki shows how I got the Hackhawk flying with the TinyPICO, using my favorite IMU solution and some small additions to my platform-independent C++ flight-control firmware toolkit.  Future plans for this project include: Finding (or designing) an IMU that will mount on the TinyPICO without sacrificing two of the GPIO pins to serve as power and ground. Switching from standard / old-school ESCs to DSHOT600, using C++ code I’ve already tested on ESP32 boards. (The ESP32’s RMT signal module and FreeRTOS kernel make this especially easy.) Using the TinyPICO’s on-board Bluetooth (or wifi) for real-time sensor telemetry, and possibly even control from a mobile device.

Drones are doing everything in agriculture from aerial imaging to fighting global mega pests

Drones might be seen as pests by Gatwick Airport traffic control, but increasingly farmers are beginning to see them as pest-killers. This is one of many uses drones have in agriculture. One obvious use is for aerial images, which has led to its take-off in the consumer market. But this same use is making it popular in the agriculture sector. Drones take the hard work out of planting European start ups such as HummingBird Technologies and Delair offer aerial imaging for precision agriculture. One of the most radical ones is British start up BioCarbon Engineering which stated its goal is to plant 500 billion trees by 2060. Its drones fly 3m above the ground and drop two seeds per second. BioCarbon Engineering technician prepares the UAV for the seeding demonstration at Ellerslie site in Edmonton. It is targeting areas affected by logging and natural disasters such as bushfires. Beyond this it can also monitor the growth of seeds. Greening Australia is one of the organisations in partnership with BioCarbon. Drones can also seek out weeds that humans either cannot or take lengthy periods of time to discover. Beyond just being reactive, drones can also monitor crop conditions on an ongoing basis. In July, Iowa-based Rantizo won the right to conduct drone-based agricultural spraying and provides solutions to the entire Midwest. Founder Michael Ott said this could also solve labour shortages that come at the same time food needs are booming. “Soon there will be 9 billion people in the world
