Trifecta Mini Tricopter Build 6

Trifecta Mini Tricopter Build
It was a few month ago when I saw the Trifecta Mini quad at least 8 weeks prior its release. Hobby King did a promotion tour across Australia and also did a stop in Penrith, which is just about 25 KM from my place. This was the rare occasion getting hands onto a HK product ...

SD2IEC on ATMEGA32 – easier data exchange with my C128 5

SD2IEC on ATMEGA32 - easier data exchange with my C128
Recently I discovered that my Time Pilot arcade PCB is broken. It works partly, its the graphics that is messed up. The cause is an eprom, where all of its legs on one side, just rusted off the socket. Some of these old PCBs are in rough shape. Not always treated well – especially after ...

Saablin on Raspberry or another RPi in a car project – Part1 5

Saablin on Raspberry or another RPi in a car project - Part1
It was time for a new geeky project. What could be more geeky than having a Raspberry in a car, talking to the stock radio and pretending it is a CD changer? It can also throw some messages on the information display – like the title of the current MP3 and of course it listens ...

Help, my HobbyKing order is not getting shipped! What can I do?

An experience I just collected recently. That orders are delayed is nothing new. That can be extremely frustrating, when you selected an ‘Express Shipment’ option, willing to pay some extra bucks to get the stuff fast. But there is not much you can do about the usual delays, which are around 3 – 10 days. ...

Reptile500 Motor Upgrades

Reptile500 Motor Upgrades
I was not getting happy with my old KEDA motors. The quad is a lot heavier than the F450 Flamewheel and the performance of the motors measured by some forum users, was not on par with what I was experiencing. After researching I found that some people were using the NTM Prop Drive 28-26 with ...

Turbo Charge your old Galaxy Tab 10.1 without KitKat or JellyBean

My first and only tablet, the Samsung Galaxy Tab 10.1. Recently I was getting a bit annoyed by it. I tried some custom ROMs already a year back. To get from Ice Cream Sandwich to Jelly Bean and later Kit Kat. I felt never so confident about my own decision. The Samsung TouchWiz UI is ...

Reptile500 as ultimate Low Cost FPV machine

Reptile500 as ultimate Low Cost FPV machine
I finally completed my project with the Reptile500 frame, ordered from Himodel. The same frame is also available from Hobbyking, when its not on backorder. It doesnt come with lots of accessories. Just a set of screws, for arms, top/bottom plate and two small fiber glass plates for the camera. In one you would drill ...

Reptile500 – my new FPV quadcopter project

Reptile500 - my new FPV quadcopter project
FPV flying is more and more fun for me. The X550 quadcopter does very well on this part with the MultiwiiPro board running MegapirateNG. But my problem is space for all the FPV equipment and the props, which blocking partly the view of the camera. In my last post I was thinking about the Hobbyking ...

X550 upgrades and MultiWii Pro with MegapirateNG 2.8 1

X550 upgrades and MultiWii Pro with MegapirateNG 2.8
The configuration of my quad has changed a lot from my last posts where I wrote about it. The motors and ESCs are still the same, but I upgraded from 8″ to 10″ inch props. This was a good decision, the quad moves a lot better with them. But the EMAX CF2822 seem to be ...

Different approaches to list open network connnections on your Linux server

Often we have good reasons to ask, who is connecting to our server or what process is using which port? There are some simple ways to verify that. A good start is always the NETSTAT command. Shell netstat -tn tcp 0 0 10.10.10.228:46057 74.125.135.139:443 ESTABLISHED tcp 0 0 10.10.10.228:44840 64.91.231.216:80 TIME_WAIT tcp 0 0 10.10.10.228:52012 ...
