How Raspberry Pi Zero got Ardupilot, hopefully flies

Well, this is a story about how Raspberry Pi Zero got Ardupilot, hopefully flies away and gets back safely 🙂 I wanted to make this a professional looking PCB, with smd components, everything crammed on it, but for that, I might as well get a PXFMINI. I changed my thinking, and built a flight FC

DT750 motors, a shaft replacement

I have a couple of DT750 motors, well known from David Windestal’s first tricopter. These were my first order on hobbyking, so they’re old… really old. Shafts have been slightly bent from repeated crashes, but dt750s look good. I had the sudden urge to build another quadcopter the other day, and me, being cheap, I used what I had at

Quanum Venture FPV quadcopter with APM flight controller

I had a couple of spare sets of motors and ESCs.. It was only logical to buy a new frame. I also wanted to move the APM to another multi, that I could carry around. I eventually decided on Quanum Venture FPV quadcopter with APM flight controller fitted onto it. The package arrived a couple of days

DIY 32ch FPV 5.8ghz LCD

If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying 🙂 I really didn’t want to buy an overly expensive 32ch FPV LCD receiver, so I made my own DIY 32ch FPV 5.8ghz LCD, that is compatible with EVERY transmitter on

eeepc, android x86, external GPS

Awhile back I got an Asus EEEpc 1005p. Those tiny laptops were all the hype back then. It sports 1.66 ghz Atom processor, 2Gb ram, 160gb HDD… same as my Sony “smart” phone, perfect for android. What am I going to make with it? Eeepc, android x86, external GPS… get it? 😀 There exists an android image for that

Ardu Pilot Mega Telemetry-Wifi bridge with ESP8266

If you have an APM (or compatible) flight controller, and Telemetry set, chances are, you’ve hooked it to your smart phone. You need a special USB cable, called usb OTG cable. It convinces your phone’s usb controller to read other peripherals. But cables break, right? Well, mine did… I couldn’t bother fixing it, so I

Multiwii spektrum Satellite ….. Equipment fail…

Pokvaril se mi je Spektrum full range receiver, pa se mi ga ne zdi vredno popravljat… je bil DSM2. Satelit pa dela… Zato ga bom priklopil na Multiwiija, ki ga uporabljam na avionu. Dobro je vedt, da je satelit 3v3, ostalo pa 5v. zato potrebujem na MW en 3v3 regulator. Uporabil bom MCP1700, ker jih

Android x86 laptop + zunanji GPS = ?

Par let nazaj sem dobil Asus EEEpc 1005p. Specifikacije so super, 1.66ghz Atom procesor, 2Gb rama, 160gb disk. Overklill za android 🙂 Android x86 za eeepc sicer obstaja, ampak ne 4.4. Zato sem rajs nalozil Android-x86 4.4-r1 live & installation iso. Standard instalacija: s programom unetbootin zapeces sliko na usb, in z usbjem zazenes laptop. Pri

MultiWii Voltage sensor

Zadnic sem napisal, da bom naredil voltmeter za multiwiija. No, pa gremo… EDIT: TO JE ZA 3CELICNE BATERIJE! V config.h je odsek za voltage monitoring. Najprej ga je treba vklopit (ODkomentirat je treba #define VBAT) /********************************************************************/ /**** battery voltage monitoring ****/ /********************************************************************/ /* for V BAT monitoring after the resistor divisor we should get [0V;5V]->[0;1023] on

HobbyKing 30A UBEC + SimonK firmware

Dobil sem stiri nove ESCje za quadcopter. HobbyKing 30A UBEC z modrim shrink wrapom. Sej so vredu, samo predolga uporaba na multikopterju jih v teoriji lahko unici. Resitev: nov firmware. Obstaja en, preverjen, pa za skoraj vse ESCje, razen za tiste z SiLabs procesorji. SimonK je tip, ki pise te fwje. Treba je ugotovit kater procesor

MultiWii update

Prejsnji prototip MultiWiija je sicer prestal test, ampak sama ploscica je bila odprta, pa nic kaj posebej lepa. Pa tudi Aruino Pro Minija bi rad uporabljal za kj drugega heh 🙂 Zacel sm risat novo ploscico, tako, ki ne bo uporabljala Arduino Pro minija, ampak samo Atmega328. Poleg tega hocem Bluetooth, 10DOF (GY80), buzzer, AUX1,
