A logic analyzer for under $5

Recently I needed to get myself a logic analyzer. But for what I needed I didn’t want to spend much money on one. As I was surfing the web for an answer I was coming along a project called Sigrok. You can find out more about it here (sigrok.org). It’s basically a cross-platform signal analysis software. It’s all Open-Source and it supports many different hardware types. Read below how I came to my super cheap logic analyzer solution.

A Little Layout Helper

When designing a PCB I often come across thoughts like: How thick is a 12mil trace really? Okay, it’s around 0.3mm but how wide is that? Or: is this part an 0805 or an 0603 resistor? Is that part a SOT-23 or a SOT-323? And can I hand-solder that part with the standard footprint? There are countless of these questions. Here I present to you a solution that works at least for me:

Andonstar USB Microscope – This is not a review


I recently had to do some surface mount solder inspection. The chip – one of these tiny little 0.65mm pitch SSOP-28 packages – apparently stopped working. Was there a problem with the soldering? I didn’t know. But I did some rough handling of the PCB. So how to check? I thought: Ruben, get yourself an USB microscope. Continue reading Andonstar USB Microscope – This is not a review
