The Filmomat Home Film Processing System

The death of film has been widely reported, but technologies are only perfected after they’ve been made obsolete. It may not be instant photography, but there is at least one machine that will take 35mm film and 5×7″ prints and develop them automatically. It’s called the Filmomat, and while it won’t end up in the studios of many photographers, it is an incredible example of automation.

The Filmomat is an incredible confabulation of valves, tubes, and pumps that will automatically process any reasonably sized film, from 35mm to 5×7 color slides. The main body of the machine is an acrylic cube subdivided into different sections containing photo processing chemicals, rinse water, and baths. With a microcontroller, an OLED display, and a rotary encoder, different developing processes can be programmed in, the chemicals heated, developer agitated, and film processed. The Filomat is capable of storing fifty different processes that use three chemicals and a maximum of ten steps.

The video for this device is what sells it, although not quite yet; if enough people are interested, the Filmomat might be sold one day. This is likely the easiest film developing will ever get, but then again a technology is only perfected after it has been made obsolete.

Thanks [WhiteRaven] for sending this one in.

Basic Toolkit for the Basement Biohacker

Laying hands on the supplies for most hacks we cover is getting easier by the day. A few pecks at the keyboard and half a dozen boards or chips are on an ePacket from China to your doorstep for next to nothing. But if hacking life is what you’re into, you’ll spend a lot of time and money gathering the necessary instrumentation. Unless you roll your own mini genetic engineering lab from scratch, that is.

arduino-based-biolab-data-logger-thumbTaking the form of an Arduino mega-shield that supports a pH meter, a spectrophotometer, and a PID-controlled hot plate, [M. Bindhammer]’s design has a nice cross-section of the instruments needed to start biohacking in your basement. Since the shield piggybacks on an Arduino, all the data can be logged, and decisions can be made based on the data as it is collected. One example is changing the temperature of the hot plate when a certain pH is reached. Not having to babysit your experiments could be a huge boon to the basement biohacker.

Biohacking is poised to be the next big thing in the hacking movement, and [M. Bindhammer]’s design is far from the only player in the space. From incubators to peristaltic pumps to complete labs in a box, the tools to tweak life are starting to reach critical mass. We can’t wait to see where these tools lead.

New Magnetic Semiconductor

When you think of South Dakota you generally think of Mount Rushmore and, maybe, nuclear missiles. However, [Simeon Gilbert] will make you think of semiconductors. [Simeon], a student at South Dakota State University, won first place at the annual Sigma Xi national conference because of his work on a novel magnetic semiconductor.

The material, developed in collaboration with researchers from the nano-magnetic group at the University of Nebraska-Lincoln, is a mix of cobalt, iron, chromium, and aluminum. However, some of the aluminum is replaced with silicon. Before the replacement, the material maintained its magnetic properties at temperatures up to 450F. With the silicon standing in for some of the aluminum atoms, the working temperature is nearly 1,000F.

IndieGoGo Project Offers DNA Editing For The Home

CRISPR is the new darling of the genetics world, because it allows you to easily edit DNA. It is far more effective than previous techniques, being both precise and relatively easy to use. According to this IndieGoGo project, it is coming to your home lab soon. Genetic researchers love Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) because it allows you to very precisely edit a DNA strand. Using a protein called CAS9, CRISPR can find a very specific sequence in a DNA sequence and cut it. It occurs naturally in cells as part of the immune system: by finding and remembering parts of virus DNA, a cell can recognize and attack it when infected. For the genetics researcher, this allows them to insert new DNA sequences at specific points in the genes of any living cell.

Amino Wants to Bring Bioengineering to Your Workbench

As the maker movement has exploded in popularity in recent years, there has been a strong push to put industrial tools into the hands of amateur tinkerers and hackers. CNC mills, 3D Printers, and laser cutters were all extremely expensive machines that were far too costly for most people until makers demanded them and hackers found ways to make them affordable. But, aside from the home brewing scene, those advancements haven’t really touched on anything organic. Which is a deficiency that Amino, a desktop bioengineering system, is seeking to address.

Amino, created by [Julie Legault], is currently seeking crowd-funding via Indiegogo. Hackaday readers are more suspicious than most when it comes to crowd-funding campaigns, and with good reason. But, [Julie Legault] has some very impressive credentials that lend her a great deal of credibility. She has four degrees in the arts and sciences, including a Masters of Science at the MIT Media Lab.

It was for that degree at MIT that [Julie] started Amino as her thesis. Her plan is to bring the tools necessary for bioengineering to the masses – tools which are traditionally only available in research labs. Those tools are packaged into a small desktop-sized unit called Amino. Backers will receive this desktop system, along with the supplies for their first project. Those projects are predefined, but the tools are versatile enough to allow users to move on to their own projects in the future. [Julie] thinks that the future is in bioengineering, and that the best way to feed innovation is to make the necessary tools both affordable and accessible.

The Practical Potato Cell

Potato batteries, lemon batteries, they’re all good fun for the classroom — but is there a way of making them better? [Marcel Varallo] decided to give it a shot — and we gotta admit, it’s a pretty cool idea!

Normally for these fruit and vegetable batteries you poke some leads into the battery, connect it to a clock, and bob’s your uncle. But what if we made them resemble batteries? [Marcel] took some copper pipe, cut it down to size, and poked it through a potato. Now he had a potato-cored, copper tube. Stick a zinc nail in the middle, and you’ve got yourself a battery cell! Or as [Marcel] likes to put it.. a Mar-Cell. Or the more scientific term.. the Solanum tuberosum based electron differencer V1.0.

Each potato cell produces approximately 0.8V, so if you throw eight in series, you’ll have the equivalent of a 6V battery, just maybe not the same mAh rating.

For another cool way to demonstrate electricity to youngsters, we love this lemon battery hack — it’s actually quite elegant.

Coke-Propane Rocket Blasts Off Without Ignition

Everyone’s seen the Diet Coke and Mentos “experiment” that ends in a brown eruption. But have you seen the Coke and Propane experiment insanity that results in a rocket launch? As [Itay] pointed out when he sent us the tip, this doesn’t need to be lit. The simple act of turning the bottle upside down starts a powerful reaction without any ignition.

coke-propane-rocket-thumbOf course it’s the how of this that tickles our brains, but let’s finish the setup. This starts with a bottle of Coke which is about 3/4 full. The head space is displaced by spraying propane into the bottle; propane is heavier than air. All that’s left is to turn the bottle upside down and pray it doesn’t smack anyone in the noggin as it takes off.

In trying to find an explanation for this phenomenon we came across a plausible answer on the Chemistry StackExchange. It points to the Mentos phenomenon combined with the temperature differential caused by the very cold propane. The answering user theorizes that tiny ice crystals form and when the bottle is turned upside down the cold propane and micro crystals rise through the warmer soda acting as a much more rapid catalyst than Mentos alone. Of course this is just a theory so please share your own ideas below.

We thought the folks who microwave stuff outside of a microwave enclosure had their fill of danger but this videos is also one of theirs. It should be no surprise that they also tried the experiment with an ignition source. That video is found after the break and should immediately convince you to never try any of this yourself.
