Anonymous asked: Hi Dave: Perfect template for our start up project. I understand this uses the wiki format. How do I delete your entries in the calendar so I can replace with ours? I also noted when it syncs with my Gmail calendar; I don't want group participants to view that information. Any thoughts? Thanks again for designing such a great workspace! Best to you in your research, and future work endeavors. Terri Hansen
Hi Terri,
Thanks for the kind words! The calendar on the template is just an example. To put your own events in, you need to completely replace the calendar with your own. To keep others from seeing your personal calendar, make a new calendar just for the site at the Google calendar page. When you do, follow this tutorial to getting the calendar into the google site.
Google Sites Calendar Tutorial
Best of luck with your project!
Cheers,
Dave
Google sites is intended to simplify the process of making a web site. However, the documentation can actually make the process harder than it needs to be. For example, changing the calendar on a pre-made template can drive people crazy. This example will hopefully make the process of changing site features easier.
A while back, I shared a Google site template that allows people to organize group projects.
This example will involve changing the calendar page on this site.
Step 1
Go to the site and click on the calendar page.
Step 2
Look for the “Edit Page” Button at the top right-hand corner.
Step 3
Notice that the calendar turns into a ‘placeholder’ and that a save button appears in the top right-hand corner of the screen.
Step 4
Whenever a widget (like a calendar or checklist) turns into a placeholder (ie light brown box), you can click on it. When you click on it, a little bar menu pops up on the top or bottom of the calendar. Look for the icon that has a gear or sprocket or whatever (it means ‘settings’). Click this.
Step 5
In the properties menu, a variety of options are available. At the top, you should see “Display another Calendar.” Click this.
Step 6
If your calendar doesn’t show automatically, paste a link to your calendar here. (For instructions on getting a link to put here, see the Google Calendar Documentation)

Anonymous asked: Hi!
I find your idea about Open Sensors very nice and hope you (and other) will contribute meterial very soon. I had a similar idea, to make a blog for collecting all medical and health related projects that are based on open hardware and specifically Arduino. My question is if you would like to share some of the material you got and your own creations (e.g., the EEG electrode). The blog is at medicarduino(dot)wordpress(dot)com Thanks!
Hi Charalampos,
Thanks for reaching out! The OpenSensors Project is growing behind the scenes. The goals of the project are to develop biomedical sensors using open source tools and to make them available for third world countries and the open source community. To implement devices at the clinical level requires a very high set of standards for validation and peer-review. Though this process is much slower, the integrity and impact of each sensor is much higher. Consequently, I cannot release any sensor schematic or code until it has passed at least one round of review and validation. However, I imagine that some material will have met this criteria and be made available, along with the raw validation data, near the fall of 2011.
As the project grows, I encourage you and your colleagues to take part in the design and validation process.
Cheers,
Dave Deriso
PS. I have to say, I loved your article on Open PCR. Keep up the great work!

Anonymous asked: Hi Dave,
I'll be graduating with my bachelors in electrical engineering next spring, and wish to pursue a future in Neuroprostheses and BCI's. I'm new to your blog and am not sure how much of your experience overlaps into this domain, but I was wondering if you are familiar with any good internships and masters programs I can try looking into.
I've made some good progress on the masters front, but wish to do an internship first and am not as far along. Are most of the internships that I'd find connected to academic labs, or are there many industry internships I could look into as well? I'm still learning how far along this research area is, and how far its made its way into industry.
Thanks, and hope you can help!
Tyler
Hi Tyler,
Sure, I had a similar question here about graduate programs (link here) but that was about academia.
Internships fall under the domain of industry, and therefore require careful market analysis. A recent report by the Neurotechnology Industry Organization outlines the different sectors of the neurodevice industry (link here). Choosing the best internship depends on what specific sector you want to join, and how far you want to travel to find the ideal fit. You may have to narrow your search down to neurostimulators, drug delivery, or neuromodulating devices, to name a few. Even within these domains, different parts of the brain may have radically different mechanical and computational requirements. A cochlear implant is very different from the new hippocampal device research that is sweeping the news. I recommend a few courses in neuroscience to learn more about these differences.
Without knowing exactly what sector you are interested in, I can only offer a by-no-means complete list of companies that may offer internships across a broad spectrum of sectors within the neurodevice industry:
Medtronic, Inc.
Boston Scientific Corporation
St. Jude Medical, Inc.
Cyberonics, Inc.
Cordis Corporation
Accuray Incorporated
Elekta AB
ev3 Inc.
Micrus Endovascular Corporation
Codman & Shurtleff, Inc.
Integra LifeSciences Holdings Corporation
B. Braun Melsungen AG
Terumo Corporation
Karl Storz GmbH & Co. KG
Good luck with whatever you choose, and please drop me a line when you start working at one of them!
Cheers,
Dave
When collaborating on a scientific project, it is important to keep the momentum going with each successive meeting. Meetings that lack structure often take up energy of the group and the project starts to wither. To develop a quasi-universal framework for meeting structure, I scoured the internet for “Steps to Doing Research” and have compiled a list that should hopefully focus group efforts to keeping the project moving:

![This is how a democracy begins. When the government does not serve the interests of the people, the people have the right —and duty— to overthrow the faulty state.
Though the “right of revolution” is as old as the Zhou Dynasty (1122-256 BC), the process of revolution has radically evolved with modern warfare and technology. Accordingly, the strategies of both parties, the people and the state, have adapted to the threat and potency of a digitally enhanced revolution.
Most states have prevented their coup d’état by successfully hindering the ability to assemble and communicate. However, as new digital communication tools, such as Twitter and SMS, have become more available to people in less advanced countries, the ability to assemble has been restored. In correlation with the availability of such technology, there have been several newly sprouted revolutions occurring throughout the world in the last few months alone.
Syria, Egypt, Iran, and Tunisia have all seen the same strategy of governmental response: block websites, if not shutting down the internet outright, and blocking cell phones. Thought this strategy may have been effective, the digital community is fighting back in its own way. The tools developed by this technology-based liberation front provide ways to communicate through narrow and censored pipes.
One such tool is Tor, a tool that “bounc[es] your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.” Tor has allowed users in heavily-censored areas to effectively hide their location by using a remote computer as a proxy. Other tools, such as Google’s SpeakToTweet, allow users to call a number and leave a voice message that will be tweeted when access to Twitter is shut down.
But where do these people turn when the government shuts down internet or cell phone service entirely? Enter Open Mesh. Open Mesh is a project that allows “citizens of the world to commonly communicate without telephone or cable companies” through a system of interconnected computers, called “nodes,” that both capture data and send data to other nodes on the network. These “mesh networks” allow information to propagate from peer-to-peer while providing access to many other peers. Furthermore, the system is self-healing such that when one node goes down (ie. is captured), other nodes can assume the workload provided they are within range of the users. This system allows the people to take control of their own communication in spite of the government, restoring their ability to organize and revolt.
As panicking states struggle to maintain control, they flail at every option they have left to prevent the public from unifying. But what happens when their tactics lose effect? What sort of control can a corrupt state exert over the people’s ability to assemble when they can’t control communication? In the next few years, it will be less and less likely that they can do anything at all.
The digital community has made their stances and support for an open internet that promotes human rights and will aid the people in fighting pro-censorship governments. In the age of communication, authoritarian governments may find that they cannot supress an informed and equipped public.
