The Macro Mondays theme for this week is "Stitch". Photo of a LabVIEW Logo hat patch. LabVIEW is a graphical programming language created by National Instruments
I took this photo to document the setup that I was using while I was working on my senior project in college. It was a little table-top particle physics project, using a detector (just off camera to the right) not built by me. I set up the data acquisition chain in the lab and wrote some software to run it. (Side note: that was implemented in LabView, which I haven’t used since. LabView is an interesting concept that lets you write software graphically, instead of in a traditional programming language. I remember waking up that semester in the middle of trippy dreams involving that programming language.)
Most of the electronics boards here were, I think, basically spare parts that my advisor (the late Prof Ulrich Becker) had brought back from CERN. I think some of it was stuff that had gone bad and thus been tossed. He would take the boards to his lab bench and figure out which solder joint had failed or whatever and fix it. (It may have also just been surplus.)
(For the curious, the bottom rack is a CAMAC crate and the rack above it is a NIM crate.)
The most interesting artifact here is the module on the very top, which isn’t connected to anything in this photo but worked just fine and was used for manual testing. It was a simple pulse counter, old enough that the display used Nixie tubes ( www.youtube.com/watch?v=wXBK__h6MY0 ). Unfortunately I do not have a picture of it powered on. Those Nixie tubes were so cool. The hand lettering in orange paint says “KF GRP”. This was a reference to the Kendall-Friedman Group. Henry Kendall and Jerry Friedman were the MIT part of the MIT-SLAC deep inelastic scattering experiments that discovered the quark structure of the proton in the late 60s and early 70s. Kendall, Friedman, and Richard Taylor won the Nobel Prize for this in 1990. So I always assumed that this was surplus left over from that era, although that is an assumption.
Henry Kendall assisted as an instructor for a small lab component of a class I had as a freshman in the fall of 1998. (Physics majors don’t take a “real” lab class until junior year, but this was some very light introduction to the lab environment that was folded into another class.) I distinctly remember him gently scolding me for showing too many significant digits in my numerical results. It’s a lesson I never forgot! Only a month or two later, he tragically died in a diving accident in Florida. I saw Friedman give a lecture at MIT at some point. I don’t recall if I ever encountered Taylor when I was at SLAC.
This lab was in Building 44 — the MIT Cyclotron building, which has since been demolished. I must have an old film picture of the cyclotron somewhere. I should see if I can find one. (The cyclotron dated to about 1940 but I believe the building was newer [ physicstoday.scitation.org/doi/10.1063/1.3058412 ].)
What to do with the leftover "I love Labview" M&M's from NIWeek? The Lego Computer Programmer decided to decorate his cubicle.

Athena Marneris studies what makes glass tubes implode. Marneris first came to Brookhaven National Laboratory (BNL) as a summer intern working for Charles Theisen in the Collider-Accelerator Department (C-AD). She used LabView, a visual programming language, to streamline the user interface of existing C-AD software. During her final poster presentation, Marneris met research engineer Rahul Sharma, who was intrigued by her work.
“We had been teaching LabView to another intern, but he had to return to school,” Sharma explains. “Athena seemed to have a good hold on the program and, after talking to her, I had the feeling she could handle a problem we were trying to solve.”
A, very basic, voice controlled robot. The robot sweeps the microphone in a returning circle pattern and turns and heads towards the loudest sound from the last sweep.
The robot is voice controlled by watching the microphone position and speaking to the robot when the microphone is pointed in the right direction.

A sheet of Graphene only one atom thick has been imaged by the fastest atomic force microscope in the world, built by Dr Loren Pico and myself. The
Microscope scans the surface thousands of times each
second with a sharp probe to build up a 3D model of the surface. This image was taken in 0.1 s and shows an area 4x4 microns. The Graphene sheet rucks up like a cloth at the edges giving a macro feel to this nanoscale surface. This image was processed using software I have written in LabVIEW.

THIS is why I haven't really been dorking with my camera recently.
The boxes on the left are microprocessor control boxes that will replace most of the slave labor (currently performed by: me!) in my shop. They allow the remote startup and shutdown of the processing equipment for parts coming off my 3D printer. No more driving 40 minute round trip in the middle of the night just to turn an oven off, or planning my lunch break around when a dip tank needs to be preheated.
I could have purchased off-the-shelf hardware here in the US and it would have ran me close to $3k to get the shop retrofitted. Using parts purchased in Hong Kong, I was able to complete the entire project for about $300. Plus, I learned how to do embedded systems programming along the way - these boxes are my first attempt at firmware programming (writing code that runs on silicon chips inside consumer electronic devices). I started learning Microprocessors in Aug of last year, but then my day job started kicking my butt and well, it got back-burned pretty quick. Over Christmas I picked things back up and I've been busting my butt since I got back from SE Asia in my shop...
The boxes talk over USB! Inside the box a special chip converts the USB back over to serial. Even my day job isn't running this; as a result we are limited to having at most 2 instruments per computer, where I can run the entire shop off one machine. The machine also has special remote-access software loaded, so anywhere with an internet connection I can remote control all the equipment. Schweet.
Now for a little bit more coding to get the Labview UI to talk to these buggers....
We found Yoda at one of the NIWeek displays. That makes National Instruments a very cool company in my book :-)
What would I need with both an old Dell and an old Apple G4? Well, the Dell makes a great paperweight and LabView platform, and the Mac is a good backup machine, records audio from our Motu firewire encoders well, and is a great little server. Also present are my precision 10 Ω load, and the going-away present I got when I left Penn State's Materials Research Lab.

Good news for users of mobile devices who enjoy accessing multimedia content and social networking applications on the move!
Researchers at Nanyang Technological University (NTU) are exploring ways to bring the speed and quality of wireless network communications up to par with that of wired communications. Better yet, their goal is to develop wireless devices that offer ultra-high-speed mobile broadband services at virtually zero cost to the user!
All these could become possible as NTU and National Instruments (NI) join hands to develop the next-generation wireless communication technologies which are cheaper, faster, more reliable and more pervasive.
Both parties formalised the partnership by inking a Memorandum of Agreement (MOA) at NTU today.
Under the NTU-NI Wireless Research Programme, NI will provide $2.07 million worth of equipment that will be installed at the Positioning and Wireless Technology Centre (PWTC), a centre under NTU's School of Electrical and Electronic Engineering (EEE). One key goal of the NTU-NI Wireless Research Programme is to develop future wireless communication protocols. The research team will be using the equipment to research into the practicality and performance of various wireless techniques.
PWTC's Programme Director for wireless network research, Assistant Professor Ting See Ho, explained, "One of the major problems faced worldwide currently is the increasing shortage of usable frequency spectrum, which is further aggravated by current spectrum allocation regulations. My research team aims to address these issues by developing the next generation of wireless communication technologies that are able to relay radio signals and scan for available 'holes' in airwaves without interfering with the incumbent users. This would mean that users can enjoy the highest quality, best performance and most cost-efficient networks."
"This project will not only bring about a technology breakthrough; it will also have a profound impact on current business models and inspire new designs for various wireless applications for the benefit of both mass-market and military users," added Assistant Professor Ting.
"Wireless communication research is gaining tremendous interest from the industry and NTU is a top-notch technological university with strong international standing in this field," said Chandran Nair, managing director for NI ASEAN. "We are pleased to equip PWTC with NI's technologies and support NTU's research efforts towards developing wireless technologies that will impact everyday life."
"This partnership demonstrates NTU's active collaboration and sharing of resources and expertise with our industry partners," said Professor Kam Chan Hin, Chair of EEE, NTU. "We look forward to leveraging NI technologies in our research centre to expand our research and training capabilities at NTU. We will also make good use of the equipment for teaching purposes to prepare our graduates for professional careers in high-tech industries and to expose them to advanced research."
"The NTU-NI collaboration is a testament to our long-term community engagement. We look forward to helping enhance science, technology and engineering education and research through partnerships that will take academic research to a whole new level," said Victor Mieres, NI's vice president of sales for Asia

Labview práctico con aplicaciones surge de la necesidad didáctica que se requiere en la enseñanza de Control de Procesos y su implementación real. La experiencia de los docentes, con la herramienta, les permite ver cuáles son los puntos importantes para que haya un aprendizaje significativo entre los estudiantes.
En el control de procesos se utilizan, muy a menudo, sistemas de mando a distancia desde el computador, llamados sistemas SCADA (Supervisory Control and Data Acquisition). Es decir, adquisición de datos y control supervisado. Se trata de las aplicaciones de software especialmente diseñadas para funcionar sobre computadores en el control de la producción. Este sistema proporciona comunicación con los dispositivos de campo como controladores y PLC's.
El libro desarrolla una serie de ejercicios prácticos que conducen al lector a lograr las competencias sobre el manejo de la herramienta y el modelado de problemas del mundo real.
