These builds are compiled with the newest version of ProxSpace and are always up to date. Here I will post the latest compiled Windows versions from the official Proxmark repository and some forks. If you want me to add a fork please contact me.

Warning Proxmark3 Easy users: make sure your Proxmark does have 512KB of flash otherwise these builds might not work!

Ogee spillways are the gold standard for dam spillway design, known for their high discharge efficiency and structural stability. When optimized, an (Excel) tool can transform a time-consuming, iterative hydraulic process into a precise, instantaneous computation. While manual calculations involve navigating complex USBR (United States Bureau of Reclamation) or WES (Waterways Experiment Station) tables, a "better" Excel spreadsheet streamlines this, ensuring accurate profiles and discharge coefficients ( Cdcap C sub d
Here is a comprehensive breakdown of why spreadsheet-driven design excels, the mathematical frameworks it automates, and its practical engineering limitations. Why an Excel Framework is Superior 1. Instant Iterative Feedback
Let’s be fair. An XLS is terrible for:

Help you set up the iterative calculation to find the design head ( Hdcap H sub d Explain how to calculate the discharge coefficient ( Cdcap C sub d ) for an inclined upstream face.
A well-structured ogee spreadsheet reveals mistakes immediately. If the upstream face slope changes, and the crest shape suddenly looks unrealistic, a conditional formatting rule can flag it. Black-box software may simply produce wrong profiles without warning.
Determined using the standard weir equation , where the discharge coefficient ( Use hydraulic modeling software for what it is
Spillway design is an iterative process. You must constantly test how changes to the reservoir water level or the spillway height impact the total water discharge.
For decades, the humble Excel spreadsheet—affectionately known as the .xls or .xlsx file—has been the silent workhorse of civil engineering. When designing an , the standard workflow for many mid-tier firms and government agencies still begins with a template search: “Ogee spillway design.xls better” .
Using an Ogee Spillway Profile Spreadsheet simplifies the complex mathematical relationships defined by the U.S. Bureau of Reclamation (USBR). (PDF) Ogee Spillway Profile: Spreadsheet - ResearchGate
The search phrase reflects a pragmatic truth: transparent, iterative, and accessible beats powerful but opaque for most hydraulic design tasks. A well‑crafted ogee spillway spreadsheet puts the engineer in full control, eliminates chart‑reading errors, and turns days of work into minutes. That is why, in design offices from Denver to Dhaka, the humble .xls remains the quiet champion of spillway hydraulics. Why an Excel Framework is Superior 1

There are currently builds for two different Proxmark3 repositories. The official Proxmark repository and the RRG / Iceman repository, with the latter having multiple configurations.
This is the most stable firmware for your Proxmark3. It does work on all Proxmark3 devices and is a great starting point, but might lack some features.
The RRG / Iceman repository is bleeding edge with many new features, but it might not be the most stable. It is designed to take advantage of the Proxmark3 RDV4 hardware. This firmware requires 512KB of memory, if your Proxmark3 has less than that and you still want to use it, follow 256kb versions.
Please refer to the Differences section.
Open the Device Manager on your PC and go to the Ports section. You should see COMX, where X is the port number. Make sure this port is your Proxmark3 by unplugging your Proxmark3 from your PC, now the port should be gone.
There were community efforts to creating a GUI, but no available GUI does support all features of the Proxmark3 client.
All binaries are created using ProxSpace and the corresponding Proxmark repository. If you don’t trust the binaries and want to compile the Proxmark firmware yourself look at the Proxmark repository for more information.
Many users have no interest in compiling the Proxmark firmware themselves, especially when they only want to use their proxmark3 without modifying the source code.
This usually does happen when switching between the official repository and the RRG repository, it is nothing to worry about. Run FLASH - Bootrom.bat or pm3-flash-bootrom.bat first and then FLASH - fullimage.bat or pm3-flash-fullimage.bat
Your Proxmark has only 256KB of flash and the firmware you are trying to flash exceeds this size. You need do disable some features and compile the firmware yourself. See 256kb versions.
This usually happens when trying to flash the RDV4 firmware on a Proxmark3 that is not a RDV4.
When coming from an unknown firmware you might need to force the COM port, open pm3-flash-bootrom.bat and pm3-flash-fullimage.bat in the editor. Change the line that contains the bash command to bash pm3-flash-bootrom COM3 and bash pm3-flash-fullimage COM3, COM3 needs to be replaced with your acctual COM port. Additional information is found in the pm3*.bat files.
