hello again If you, like me, have bought a flip32 AIO board, you probably got it because it was cheap… like 10usd cheap. I got it from hobbyking as part of the weekly actions…. I don’t really have use for it at the moment, but a quick look in my parts bin, and it hit …
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 …
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 …
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 …
Ever wanted to add PosHold or RTH to cleanflight? If you have a CC3D, I can help you. Enter CC3D barometer, compass, gps, OLED addon board. Barometer, magnetometer, GPS and I2C breakout board for CC3D on Cleanflight.You can also plug in an OLED display and GPS. Board size is the same as CC3D (36x36mm), and …
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 …
So I saw a post on the internet a couple of weeks ago, and I thought it was just genius. To make it short, the RX5808 module is a mere 8 channel receiver, but with SPI comm enabled, you can “hack” it to use every 5.8ghz channel, thus making it a 32ch FPV receiver using …
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 …
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 …
I have a few parts laying around, and I didnt want them to do to waste. Is there a better use for them? No, I dont think so 🙂 So, I want a spider quad. I cloned a TBS disco once , but I crashed it.. in the middle of the road… right in front of a …
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 …
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 …
Heavy Aerial Lift… ta quadcopter sem sicer ze imel doma, ampak sem ga parkat dal narazen, pa enkrat razbil. Zdj sem se pa odlocil da ga popravim. Enega od ALU boomov sem skrivil, zato sem narocil nove… 3cm daljse, karbonske. ESCje so moji najljubsi Hobbyking F30a. Nisem se se odlocil med SimonK ali BlHeli, zato …
Ker je bil pocen, sem se odlocil kupit komplet telemetrije za APM. Dobil sem en Air modul, Ground modul, dve anteni in kable. Pri ceni okol 10e, se splaca pogledat kako stvar sploh skupaj stoji… No, “stoji”… cudn da sploh stoji skup. Kvalitetna spajka se sveti, ta se ne… niti slucajno. Antene so zaspajkane …
Tako… Pocket Quad se je pokvaril. Po pikanju z multimetrom sem najdu napako. Izgleda da se je pokvaril step up converter. To je 6-nozni chip na levo od C13. Atmega sicer deluje na 1s LiPo, ampak za motorcke je pa malo presvoh. Step up 3.7v porine na 5v. Izgleda da se je pokvaril tudi en …
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 …
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 …
Ker bo to “delavski” flight controller, ne bom investiral v drage GPS module, ampak bom uporabil kar imam doma. Torej… imam en cheap bluetooth modul, kateregea bi povezal na DIY MWC. Problem je, ker je serijski in prepocasen. Ta serial signal je treba spremenit v i2C. Poleg tega bi pa dodal se lcd 🙂 Tole …
kupil sem si majhn quadcopter. Zraven sm dobil dve Lipo bateriji in usb polnilec. Vse ok, ampak racunalnika nimam vedno pri roki, avta pa tudi ne bom vlacil sabo 🙂 Torej… Potrebujem mejhn, prenosni polnilc, ki lahko baterije polni z drugo baterijo, najrajs z 9V. Kaj potrebujem: Lipo polnilec.. MAX1555, imam se dva (Maxim, hvala …
Ker je ze cas da naredim kaj novga za 4kopter, sem se odlocu da reprogramiram ESC. Imam HobbyWing Skywalker 4x20A, ki je vbistvu 4in1 ESC. Original fw je dober za letala, ampak za multikopterje je pa prepocasen, ima preslab odziv na premike. Obstaja vec vrst ESCjev, ampak v glavnem se uporabljajo tisti, ki so grajeni okrog …
