The design models have been 3D printed and assembled. We made two devices, only the outer casings are different in the two models. One is printed on a SLS 3d printer (Nylon PA-12) and another one with an FDM 3D printer (PLA Black).Both the models are...
This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
I added a version for regular 8. Don't forget to use the correct sprocket!Also - for R8 and S8 you need to adjust the crop settings (line 20 onwards). This is necessary, because your camera / lens setup will most likely be different to mine.
I differentiate between regular and visible passes of the space station (setting showAll=f or =t in the call to heavens-above.com from the python script)The list of regular passes contains ALL of the passes, the list of visible passes contains a...
A new Thiiiiiiiing is being made. Stay tuned...This Thiiiiiiiing is based on a motor and a Li-ion cell I bought in RC hobby store. The motor spins at 39kRPM (650 Hz), which is faster than regular Dremel's max of 30kRPM. It also has quite a bit of power....
Lions long struggled with finding the library that contains a symbol. The UNIX gurus can do it with a find command & some regular expressions. Lions wanted a simple command to run, without any effort looking up regular expressions. https://cdn.hackaday.io/files/1380505906331200/symbol.cThis...
I'm working on wiring up just one of the shift registers to the Nano I have and running a binary counter just as proof of concept. I haven't used shift registers before, nor have I messed with the Arduino Nano, although I know my way around with the...
I found 2 wrong schematic symbols, which got fixed on the rev 01 board with 1 deadbug IC and one that was not required for regular operation. The interested observer will find those fixes in the image of the board.
With PDM, SPI or even GPIO can be utilized to receive the audio input. This is much better than just i2s. In fact, PDM can be made to work as an i2s stream, yet is compatible with regular SPI or fast GPIO input.
I just got a few CNY70. Unfortunately they are a bit too large... 6mm instead of 5mm wide, so I can't use regular 5mm paper... I still have to see what I can do with the BPW34.If I can find them in my workshop, since I got them before the renovation......
