The SMART Digital DDA-C is a compact positive-displacement diaphragm dosing pump with variable-speed drive (stepper motor) and intelligent control electronics with minimum energy consumption. The SMART Digital Dosing series operates at full stroke length to ensure optimum accuracy, priming and suction, even for high-viscosity or degassing liquids. Depending on the set capacity, the duration of the discharge stroke varies, ensuring an optimal, uniform and continuous discharge flow. The click-stop mounting plate allows installation in three different positions without using any additional accessories. The control cube can be easily turned to the front, left or right position. The click wheel and the multi-coloured backlit graphic plain-text LC display enable intuitive commissioning and operation. The control elements are protected by a transparent cover. The DDA-C has built-in connectivity that allows easy setup and tracking via the Grundfos GO app as well as easy integration into a Modbus RTU or TCP bus system. The dosing head includes the following parts:

  • A durable and chemically resistant full PTFE diaphragm,
  • Double ball valves for maximum dosing accuracy,
  • A deaeration valve for easy start-up.

Operation modes and functions:

  • Manual dosing in ml/h, I/h or gph.
  • Pulse control in ml/pulse (incl. memory function).
  • Analog control, 0/4-20 mA (scalable).
  • Pulse-based batch function in ml, l or gal.
  • Timer-based batch function (dosing timer cycle or week).
  • Fieldbus control (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).
  • Cloud control and monitoring (Smart Digital Chempairing Suite; Grundfos Connect).

Other features:

  • Auto deaeration during pump standby to avoid stand-still due to air-locking.
  • Two SlowMode steps (anti-cavitation), 50 % and 25 % maximum flow, e.g. for high-viscosity or degassing liquids.
  • Max. Capacity to limit the capacity of the pump to a set maximum.
  • Service information display to show when service and which wear-part order numbers are required.
  • Two-step key lock function to protect the pump against unauthorised access.
  • Multi-parameter dashboard function to provide further information on up to 4 parameters.
  • Counter for total dosed volume (resettable), operating hours, etc.
  • Save, copy and load customised settings as well as reload factory settings.

Signal inputs/outputs:

  • Input for pulse, analog 0/4-20mA, external stop.
  • Input for low-level and empty-tank signal.
  • Two potential-free output relays for max. 30 V AC/DC (configurable, e.g. alarm, stroke signal, pump dosing, timer etc.)
  • Output analog 0/4-20mA.
  • Fieldbus communication interface (integrated Modbus RTU and TCP; Profibus DP, Profinet and Ethernet IP via CIM/CIU models).

From the creator of the Godot Recipes site!
Format: Paperback
Absolutely loved this, takes you through building 5 different games from start to finish, and explains not only how to do things, but it also explains the why! Throughout the course of making these 5 games, you also get introduced to many of the Nodes within Godot, explanations on how they are used, and gives you some experience using them! Feels good to add more tools into your toolkit as you become more familiar and comfortable using more Nodes. Even though this book is not intended for beginners, I would still recommend this book. It comes with a link where you can download example files and get going with minimal effort, however to get the most out of the book I would try to recreate stuff yourself. I found it very useful for easing myself into trying out 3D development. I've been doing 2D for years, and am currently developing a 2D game in Godot, once I complete that I'll be diving headfirst into 3D and this book gave me a lot of insight, and I feel much better about the whole process.

would have been better as a blog
Format: Paperback
First off, I have read over half of this book, but ultimately decided to put it down because it had a low signal-to-noise ratio. If the second half is filled with magic, I apologize in advance. What I liked: * The author is very honest. He does not shy away from discussing his failures (and successes). * The postmortem on the game "Life of Pixel" was especially good. * Interviews from various indie studios are sprinkled throughout. What I did not like: * A number of pieces of information were already out-of-date. This makes me think that the concepts should have been discussed at a higher level. For example, specifics about game engine costs are discussed. These numbers have changed since E3 of this year. Definitely recheck any information before formulating a plan based on the book's recommendations. * The indie studio interviews are a wasted opportunity in that they each interview has the same set of questions. It's like a questionnaire was sent out via email and the responses were pasted into the book. * When discussing commercial options, such as engines or other software packages, blurbs once again appear to be cut-and-pasted (this time verbatim from the package's web site). * Some of the advice is too broad and too light. For example, when writing about how to create a press release, the author discuss how to write in the active voice. I'm frankly not looking for writing tips in my Indie Game Developer Handbook. * The book is filled with tons of web links. My paperback copy was not so useful here. I ultimately left the book with the impression that the information would have been much better in the form of a blog. The author could have really gone in depth with the parts of the book that shined while keeping the surveys of topics in a form that serves them better (i.e. web links on the web).

Helpful information and Questions to consider
Format: Paperback
As a writer of science fiction and fantasy I had already looked into the physical aspects of the worlds I was creating, but I quickly realized I needed to include society and culture in the worldbuilding. I started a search for information, questionairres, or guidelines to use and found very little that would be helpful to me as a writer. Until I came across this book. It's exactly what I needed. It touches on multiple aspects of beliefs and practices and asks questions to help you think through what you want for your worlds, even if it's mostly backgroud. A very useful tool.
