I love physics hacks, and I consider phase shift measurements in general as a great hack. As a consequence, I love laser distance meters.
I recently bought a Metz 50 AF-1 N flash that I’m very happy with. One of the reason why I bought this one was that it has a USB port to upgrade the firmware. (Call me crazy, but that’s a valid reason for me.)
Looking at their firmware, we find a number of “.mtz” files that all look - weird. Their entropy is much too low for a real encryption scheme (plus they don’t seem to have any length alignment). One file, MB50AF1_NikonV12.mtz in my case, looks like it’s the actual firmware for the device.
I was looking for a successor to my last project. Some time ago I’ve bought the most cheapest Gigabit-Ethernet switch I could find. It was a TP-Link TL-SG1008D - 8 ports, GigE on all of them, and in the end, it was much bulkier than I expected it from the photo.
It served well, and I finally decided to open it up.
From time to time, I’ll rip apart devices just because I want to know what’s inside. I mean, usually you know what’s inside - but sometimes, there’s more. Those are the happy days. Sometimes, it’s just a tiny PCB and a lot of weight. Those are the not so happy days.
I’ll start this series - which hopefully evolves a bit more than the last series I’ve started here (which I still intend to finish… some day) - with the Tektronix TPA-BNC.
I’ve bought a HDMI Audio Splitter from dealextreme. I’ve ripped it open.
The thing has two HDMI inputs, one HDMI output. So far it’s boring - most of these devices just use analog switches to route the HDMI. However, this thing also has a coaxial and optical SPDIF output. That means it must at least being able to parse the HDMI stream, potentially decrypt it (if HDCP is used), and extract the audio information.
8 ports should be enough for everyone - but 24 ports are so much cooler. The more, the better. I’ve decided again for minimum investment - 68 EUR for 24 bidirectional Gigabit isn’t that bad. It’s a TP-Link L-SG1024.
So I’ve ripped it open (you expected that, right?).
This post is about a teardown of an DPO5000 oscilloscope (DPO5034). This is a 2011, mid-range, Windows-based Tektronix oscilloscope. List price is $12.000, but eBay has them - used - down to $5500 or so if you’re lucky.
