På denne side finder du lidt om de Raspberry Pi byggeprojekter som jeg går og hygger mig med at lave.

Mit Raspberry Pi ocilloscope

Scopet indbygget i en fin laserskåretkasse

Projektet fandt jeg i MAGPI 171 fra 2018, det er Mike Cook der har lavet denne fine artikel

Her er lidt tekst fra artiklen på engelsk

Using the oscilloscope

The oscilloscope samples at 58 kHz, which in theory means you can measure waveforms at 29 kHz. But that only gives you two samples per cycle and as the samples can be anywhere on the waveform, they do not look very good. As a rough guide, you need at least ten points on a waveform to make it look like a waveform, so that gives a top practical frequency of 5.8 kHz. However, by using the Time Magnify options along with the freeze function, you can measure much higher frequencies. The time and voltage cursor lines let you find out the values on any point of the waveform, and by clicking the save functions the current cursor is replaced by a dotted line which is fixed, and measurements can be made relative to that.

Raspberry pi 400 case with built-in hard drive

Then I got all the parts 3D printed for my Raspberry pi project, it's for the RPI 400. Then it just has to be assembled.

then I collected all parts, I thought it turned out very well.

I didn't make the 3D drawings myself, found it on this link

Great work James..
