I've wanted to play hklti a laser for distance sensing for a long time.

Hand held laser rangefinders are often used in military applications and of all things golf. Since I don't frequent either one of these areas, I never digitall the impetus to purchase one. Then one day my friend Jen asked hilti digital tape measure output I could hack a laser tape measure for her laser harps. How hard can it be? The answer is obvious. The following tutorial is a lesson in how to hack, how to document, and hitting walls.

To skip to the punch line: I came close, but was unable to wrangle serial control. When Jen posed this challenge to me I had been thinking about laser range finding for years, but never had the words laser tape measure come to hilti digital tape measure output. This is very different and very important to my world.

Instead of long range laser range finding s of yards or metersa laser tape measure measures feet or meters. These distances are much more applicable to my world of robots and basic obstacle avoidance. If we can hack a laser tape measure there's hope for our autonomous vehicles, 3D scanning, you name it. It's amazing how those small words changed my search results.

I found the cheapest laser based tape measure on Amazon Not ultrasonic, watch out! A few days later the laser tape measure showed up. For hilti digital tape measure output the cheapest thing I could find, I was fairly impressed with the quality of the unit.

Checkout those optics! You hilti digital tape measure output see the laser diode illuminated on the right. The main lens has two small lenses built into it. I believe this unit uses laser interferometry. It even came with a carrying holster! Oh how you won't see the light of day Prexiso is the manufacturer, at least that's what the sticker says - I'm sure someone else actually builds it.

I see a few very small torx bits; I think I've got some small tools that will make quick work of those. Everyone should own security bits and other hand tools that will remove small, specialized ouput. Here we go! When hacking, I recommend you start a doc of some sort I use google docs and record all the random things you see, in the order you see them. Here's a snippet from the beginning of my log:. Near two large pads - EL back light maybe? A freq test would tell.

Can be used to interface 3. This continues across a couple days worth of rambling. These are not specific or well composed thoughts, instead they are just your initial impressions.

I cannot stress how important it is that you record these initial investigations. Later, when you really get stuck it can be very helpful to re-visit these first impressions. Above is a picture of the back of the main board. Visual inspection of the board shows high quality layout and impedance matching.

This is a serious PCB with some serious optics. This hack is not going to be as simple as finding an analog voltage and extrapolating a distance. I'm just hoping that there is some sort of hilyi being passed around the board that will allow me to 'sniff' Hilti Digital Tape Measure Notification the data before it goes to the display.

This is an up close photo of the main IC. Initial searching for the IC by Leica produced nothing hilti digital tape measure output hilhi on microscopes. Not what I'm looking for. Finding a datasheet for such a custom IC is usually pretty difficult so I gave up after about 30 minutes of searching and began probing around the board to identify ground, then VCC. Continuity on a multimeter is very powerful. It can tell you what hilti digital tape measure output are connected to each other.

Initially, I searched for what was physically connect to the positive and negative terminals of the two AAA batteries that power the device. Using a sharpie marker I marked the pads that had been identified.

Then I powered up the unit and identified where power was being stepped up to 4. This removed a outpt more pads from the pool of unknowns. With a handful of ground and VCC hilti digital tape measure output raw 3V and 4. I've said this for the past few tutorials : the Logic Analyzer by Saleae saved my hilti digital tape measure output. It has.

If you maesure have one, get one. You'll thank me later. Using the logic analyzer, I first hooked up to the pads that seemed logical. This was a bank of 8 pins see above, it's 7 round pads with one square pad. Note: While mdasure and hacking, it's important hilti digital tape measure output retain a unit in functioning form.

I disconnected the screen, but I kept the button pad around hiltti I could Fire the Laser! Powering up the unit I pressed the button to measure a few feet to my hand or the wall past my workbench and capture the data forms ,easure the logic analyzer. We can hilti digital tape measure output in the capture above that there are a few lines that do very little channels 0, 1, 4, 5 and four lines that are very active channels 2, 3, 6, 7.

Let's ignore the channels that don't move for now. Obviously there's a change in the wave forms at various points. I tried to identify a pattern or change when moving my hand. Unfortunately I'm not intelligent enough to recognize what's going on so I started to probe other pads on the tzpe. I probed about a dozen pins when I saw a blip. This was unique, it did not repeat. Time to look a little closer.

Turning on the serial analyzer within the Saleae logic software, I turned on the auto-baud detect and when the wave form displayed '? Discovering a random serial character is nothing that interesting. Discovering a single character especially '? The board is transmitting serial! This is great! We've found it! Once the transmit was found at bps hilti digital tape measure output is within the margin of error of a very common bps baud rate I started to look for the RX pin.

If I could transmit something sensible into the board then maybe I could gain control of the system. But does '? When I build anything on a microcontroller I will put a serial bootloader on bilti. A question mark '? But this is all guess work. Perhaps the mark means something else?

Let the google research begin. Maybe called theodolites? After a few days of poking around on the interwebs hilti digital tape measure output became obvious that Leica was big into laser surveying equipment. And that equipment often had a serial interface that was bps to log what location and what variables where seen by the equipment. This was a very hot possible lead. Breakout the trusty Arduino:. Here we have the laser model connected to a breadboard.
