Project Mosquito progress

I took some time this weekend to optimize the frame. The frame has now a dyadic setup which means the sideplates can be separated in two parts which makes maintenance on the electronics much more easier. This dyadic setup seperates the lower part which we right now call the rail and the frame housing. So it is possible to pull the main housing and then you access the drivetrain and all electronics. Weight 171,7gr without the battery. I have two 800mAh 3s sources here weighting in at 82gr (with long cables and xt60 connectors). So I will short the really long wires and change it to a xt30. This will bring the setup below the magic mark of 250gr.

Stay tuned for upcoming results within this week.

Project Moskito proto

Today I did the first maiden flight and wow… It flies like a charm even without big adjustments to the betaflight yet. I’m quite sure there is not much which can brake except the propellers.

It´s not 100% final so don´t blame me for the battery cable. I´m still at looking for the perfect position for it.

Some specs:

  • max. dimensions: 132*129*53mm
  • motor diagonal distance 135mm
  • weight  ~180gr at the moment (but there are still options to decrease)
  • 3″ props
  • full capable of 36mm (30,5mm holes) boards
  • full 1080p recording thanks to carry a runcam split
  • carbon fibre lightweight desing
  • vertical arms to get best efficiency
  • OSD
  • voltage- and currentmeter
  • videodownlink
  • super sturdy and crashresistant design
  • below 250gr (german marking rule)

 

Project: Moskito

It’s long time ago that I posted news about my latest quad project. Here it is – the brand new prototype of my moskito – a 3″ quad with full 1080p recording capability and racing formfactor. This beast is compliant with the german „below-250gr“ rule. So take your googles and punch this 135mm frame into the air and have fun with your recorded hd video footage later.

This babe will be one of the most efficient quads in this size due to it’s unique and futuristic design. Stay tuned…

Finally? -not really…

It seems like there was a new firmware and app version deployed.

I have to test if the issues are gone now completely but it seems that the artifacts issue in photos and videos is now gone and back at the quality level before the 1.6.3 version and without the other bugs. I will have some tests these days and report here.

UPDATE: ok the quality issues really seem like to be history BUT…

… right now you have to deal with constant WIFI disconnects. It´s like a nightmare what´s happening to this perfect hardware on software side. with every software update one issue is gone but a new is popping up.

Another useless app update for the Mijia Sphere

After the firmware and app update more than one week ago, Xiaomi yesterday pushed another app update on android devices.

Now we are at 1.8.1.14363 which adds new filters to the app.

I as user have still to decide to take pictures with really poor image quality but exif data in the newest version or going to the old 1.6.3.xxx version with good quality of the photos but without exif. As I mentioned in a few posts before they changed something on the compression for photos and videos. the last version I could identifiy where the issue not appears was 1.6.3

This is really frustrating what Xiaomi is doing here. Please Xiaomi again, take first care for the really flaws in your software and after that you can add gimmicks like filters and such things for playing around.

Mijia new firmware

Today I got the message that there is also a new firmware getting rolled out.

 

Tests are done so far here are my results after the latest app and firmware:

  • video drift is gone! the video stays now stable
  • exif data seems corrected also (google maps accepts the photos the same like from my theta s)
  • crumpled video and photo still exists (may I have a confirmation from someone about this issue)

 

New Xiaomi mijia 1.8 app for android

What I found out until now is that the photo quality is still crumpled… but xiaomi now includes more exif data to the photos which lets google maps inteprate the photo with correct orientation. I am still testing. The next thing will be video and the bad drift… Maybe xiaomi found finally an exit out of their app crisis.

Ripping around – Giant chair edition!

This video is more than overdue, i procrastinated editing and uploading it way too long.

This was filmed almost 3 weeks ago, we had a lot of fun and a lot of damage while flying around our local XXL Neubert (you get overpriced furniture there, don’t even ask).

First few batteries were just me ripping around the parking lot, then Daniel killed his Eachine Lizard 95 and the girls were getting hungry. Side note: Never go flying with hungry girls, unless you have no more than two batteries with you. End side note.

Anyway, then i decided to finish my last battery at the giant red chair that was standing around (it’s like 30 or so meters high, at the very least), but i did **NOT** scout the location enough and overlooked the number one enemy of every miniquad pilot: WATER! TO THE RESCUE!
