There are some beautiful and useful mechanical keyboards on the market but only a few of them are made for Mac. Matias Keyboards have a Mac layout and they also sell mechanical keyboards. But their keyboards are not illuminated. Das Keyboard has some Mac models but they also do not come illuminated. I could not find a Mac layout mechanical keyboard that has not just illuminated keys, but keys for which their colour could be adjusted. Most modern gaming keyboards offer this function.
This is simple Mars Rover model using two LEGO Mindstorms EV3 and a total of eight motors. The two EV3 are daisy chained and the model can be controlled using the EV3 IR Remote Control. The model uses the rocker-bogie suspension system including a differential in the middle axis. The two EV3s are suspended and remain horizontal in any position. There are much more complex Mars Rover models already available using many more Mindstorm bricks. My design goal was to keep it simple and experiment with the rocker-bogie suspension system. The principles works, but there is a bit too much flexibility in the model.
The 3D model and the building instructions are available for LEGO Digital Designer. The parts list and instructions are also available at Rebrickable.
Below you find the Datacolor SpyderCheckr 48 definition of patches in different color spaces, such as LAB, sRBG and AdobeRGB. Datacolor offers a lousy bitmap of the values which are difficult to read and impossible to use in a structured way. So there you go, a table of all the values that this color chart is suppose to represent:
I recently recorded a lecture I gave in Stuttgart using the latest Insta360 One camera. Since it is very difficult to stop an academic from talking the whole presentation took nearly one hour. The camera divided the recoding into several files, each around 4 GB. This is probably because they wanted to be compatible with the old FAT32 file system.
Their 360 Editing Software allows you to convert their proprietary INSV files into MP4 files and they even have a batch processing option. But the software cannot merge multiple videos into one, which I desperately needed.
Insta360 is also offering a plugin for Adobe Premiere and After Effects. After installing the plugin I was able to import the INSV files into Premiere, but the image of one of the cameras was upside down. I contacted their technical support and they explained to me that the plugin is currently not working.
I ended up having to convert all the INSV files to MP4 first and then editing them into one movie in Premiere. I have to admit that this workflow is rather inconvenient and I hope that Insta360 will either enable their editing software to merge movies or that they get their Adobe plugin working again. This seems another example of Banana Technology, it ripens at the user.
Recording a clear voice with no background noise is key for any video, audiobook or podcast. If you are limited in space and budget then you might consider building your own little sound proof voice recording box. I build this little gem from 6mm MDF and some acoustic foam taped to the box with double sided tape.
For the box you can create the drawing necessary for the laser cutter using online tools, such as Box Designer. It exports a PDF file which all the six faces clearly separated. If you are planning to make efficient use of your wood then you may prefer MakerCase. This service aligns the six sides so that they can be cut most efficiently from a piece of MDF. Here is the box drawing for laser cutter used for this design.
We attached rubber feed to the box and placed the microphone on an old mouse pad to isolate the microphone from any vibrations of the table, such as when a laptop is placed on it. Handles on the side allow for an easy transportation.
Here is a recording without the box. The microphone was placed just directly on the table:
This recording was made with the speaker sitting in front of the box speaking into the microphone.
The last example is with the speaker leaning into the box.
You will notice how all ambient noice is gone and how intimate the voice of the speaker sounds.
