Improvements to LPG/CNG Price Reporter
Project history
- Previous project: none
- last step: none
- current posting
- next step: LPG Preismelder Android app updated again
- Next project: Android App for Blackmagic Pocket Cinema Camera 4K
Wow...while the others are sleeping
I'm really getting things done here!
I just finished an improved version of my Android LPG/CNG fuel price reporter.
It should use much less battery now.
I'll test it on my way back after Easter and then release it.
improved 3d printable follow focus
With the addition of the cheap Matte Box to my 3d printed shoulder rig,
I found that with my short 50mm lens the follow focus would get in the way of the matte box.
So the night before EasterHegg I designed and printed a straight one.
It turned out that the hole for the trapped nuts was now long enough with the straight variation.
So now that everyone else is still sleeping, I corrected that and uploaded a Version 2 of my straight, 3d printable follow focus.
I found nothing else to be wrong with the first one, so it should work like a charm.
The first version works okay for the smaller skateboard wheels.
(I switched to softer inline-skate-wheels).

(EN) Thing-o-Matic delayed
I ordered myself a Thing-o-Matic as a birthday-present to myself.
It is supposed to cut down on printing time by being able to print one small part while my trusted Repman is busy printing another (possibly big) one.
Considering the extreme waiting times at Makerbox I should have guessed that I would have to wait.
Despite ordering at a british dealer who claimed to have some Thing-o-Matic already being on their way.
With Makerbot industries in the US and the shop being in the UK, for some reasons the Thing-O-Matic kit comes from DAGU in China and is stuck in chinese customs.

As Thingiverse supports flattr and I wanted to support some other blogs anyway,
I just added a flattr button to this blog and to my Thingiverse-account.
I don't expect any income at all but it can't hurt. ;)

(EN) Display Viewfinder Adapter
I am using a 3" 4:3 "Digifinder" display-viewfinder on my Panasonic GH-1 but found that:
a) The way to mount it with a rubber band is ****
and
b) I can't see the edges of the screen where battery-level and other important information is shown
This adapter fits perfectly onto the screen of a GH-1, GH-2, FZ100, ... camera and can be attached and detached without any rubber band chaos.
It allows to mount the digifinder at a longer distance and thus see more of the display.
There is even enough room in the visible area to drill some holes and insert micro-LEDs as indicators for e.g. audio-level warnings or to have some feedback that the audio recorder is actually recording at the moment.

(EN) audio remote for shoulder rig
This time I designed and printed an attachment for the RC04 remote control to the well known Zoom H4n audio recorder.
With this design you can level all 4 audio channels with your left hand without letting go of the camera.
The LEDs on the remote will turn yellow and red to indicate when the level on one of the channels is about to spike.
Of cause you can also control the level of your monitor earphones/headphones, start and stop the recording and control playback instantly after the shot is made to check the recording.
(And possibly doing it again while you still can.)

(EN) extra strong T-connector for shoulder rig
I found that the left handle of the shoulder rig was subjected to very large forces when you hit a door or something else with the bulky rig.
This is due to the long levers the handle creates.
So I designed an extra strong variation of the T-connector to hold up to such forces.
So far it works very well.
* design files on Thingiverse
* photo album
On the photos you can also see the newly arrived H4n audio-recorder and the cheap Indian matte box.
It looks more like Hollywood then a DSLR-camera now and the audio quality has drastically improved.
I'm even able to shoot stereo atmosphere and still have 2 channels left for me and an interview-partner.

(EN) some more CAD (audio remote for camera rig)
Well, I had a long evening in the hotel before I walked over to CCC Munic and did some more CAD work...
The first one is an adapter to attach this:
to this:
>
Without these cumbersome rubber-straps that come with the Digifinder and without loosing the outer 10% of the display (where e.g. the battery-indicator is shown).
So it looks like this:
and is supposed to simply clip onto the display.
The second design is an attachment to hold an RC4 remote for a the famous Zoom H4n audio-recorder onto the handle of my shoulder rig.
This way you can control the audio with your left hand while holding the camera-rig.
Both are not yet printed, so I do not post them onto thingiverse just yet.
Indeed, I may take the time to dismantle that remote (4 bolts on the back side)
and print myself a completely new case for it, that directly attached to the rig.

After nearly 1 year Google support finaly managed to work a ticket we submitted mid 2010.
Back then I took over as the new maintainer of Vespucci.
The OpenStreetMap editor for Android.
It took Google a year and now finaly Vespucci is in my (Google) Android Market account and I can release versions.
A quick group call on the mailing list showed a concensus, that it is stable enough, that I can release a new version.
Hopefully this weekend.

(EN) My YouTube channel
After the current shoulder rig with it's accessories is finished,
I'd like to try something new and start a video-channel with howtos.
Content:
The content will be mainly things I make but maybe I'll also do reports of cool events like the camps and congresses of the Chaos Computer Club.
Quality:
I'll try to keep the quality up and the rate low.
With the video- and audio equipment I've build and gathered it should be possible.
I just don't know if I'll manage to actually pull this of.
I also don't know yet if I'll even be able to keep such a thing going.
Mission statement:
I'm a fan of DIY videos but often their visual, audio and narrative quality is lacking.
That's what I'm trying to improve by example using a proper script, green screen, lighting, color correction and audio leveling.
So, visit
THE CHANNEL
and hope that it will have some first content in the following weeks.
update:(2011-04-12) added the youtube-channel to the right side of this blog.
I'm still waiting for the final audio equipment but a draft of the introductory video is already done. (I'll redo all the talking when the audio equipment is here)

The Chaos Computer Club - Freiburg is looking for a location to create a Hackerspace for some time now.
Last night I was out, meeting 3 other club members at the local airport.
Aparently the amateur radio operators have a house there that we may use for events.
They are discussing it with thei administration and we with ours and in may or june there may be a decision.

(EN) Printing a gearless follow focus
The prototype of my shoulder rig worked fine so far.
Improvements to the T-connectors are possible but it works.
Now, inspired by this DIY Gearless Follow Focus on DVXUsers, I'm printing my own improvised follow focus for this rig.
update:
The follow focus works but the skateboard-wheel I tried first has little grip.
So I replaced it with a larger inline-skate wheel. That works much better.
+ softer wheel has better grip
- larger wheel means gear-ratio of about 1:1 instead if 3:1
- heavier wheel means printing the follow-focus again with 60% instead of 20% infill for added mechanical strength
I've posted the design on thingiverse for others to print and improve.
You can see all photos in my picasa album.
Update 2:
I also added a
* counter weight this same weekend
Update 3: The printed parts are also available on shapeways. (If you can't get access to a 3d printer yourself)
Update 4:

(EN) just a bit of CAD in the morning
Managed to do some CAD work on the shoulder rig I'm currently working on.
The holes in the end pieces note go all the way through.
There are 2 models of the handle, two models of T connectors (Model B has issues with mechanical stress, so I introduced model A), two models if the overall assembly and the existing model B of the T connectors leaves more room for the wings of the wing nuts.
Also uploaded new renderings of both variations of the assembly and corrected the bolt sizes in the BOM.
...all before (hotel) breakfast.
(EN) shoulder rig: got the right bolts
Finally got toys if the way too long bolts and assembled the shoulder rig prototype with bolts if the right size. (M5x16mm wing bolts...I just love Schrauben Preisinger for having pretty much all nuts and bolts ever made in stock)
Looks much better this way.
Some last changes to the design and I hope that I can call it a finished version one after this weekend.

I already posted, that I designed a 3d printable shoulder rig this week.
Now the printer is working behind he, while I do my own work to make this rig a reality.
...I just love home 3d printing as a tool.
Half of the parts are already printed now.
Several parts got small improvements after I tried t fit them but all did their job in their very first version.
I guess it will take another day for the rest of the parts and I hope to start developing a simple inline-skate-wheel based follow-focus without gears tomorrow too.
Update: The printed parts are also available on shapeways. (If you can't get access to a 3d printer yourself)

It feels good to have some personal project to work on. :)
I hope to have a first basic rig tomorrow.

For it may be that it is miscalibrated and holes are shrinking too much while cooling down.
(deadly for things made to measure)
Update: I disabled the Skeinforge Strech-plugin and holes are fine now.

Mal sehen ob ich heute dazu komme, Test Aufnahmen zu machen...
