Arduino-Controlled Single-Leaf Shutter

Single-Leaf Shutter

[Kevin] has made an interesting camera shutter mechanism using an Arduino and a solenoid. To keep it extremely simple, he is only controlling a single leaf. In the linked video, you can see him take it through its paces from 1/125 seconds up to infinite. This is, of course, a proof of concept, and [Kevin] mentions using smaller components to make everything fit easily inside a Holga-like body. As he points out in the video’s comments, digitally controlling the flash would be a simple matter as well.

A basic camera is incredibly simple to make, and [Kevin's] design certainly isn’t complicated. That said, if you look at the big picture, [Kevin] is demonstrating how feasible it could be to build an entirely custom camera with a standard microcontroller as the brain. We can’t help but think of all of the possibilities when you are able to control the entire photo taking process.

Interestingly, [Kevin] is also behind this twin lens reflex Kickstarter project from earlier in the year. It will be interesting to see what other camera-related hacks we will see from him.

5 Year Mission Continues After 45 Year Hiatus

There have been many iterations of the Star Trek franchise since the original Star Trek 5 year mission series aired in 1966 including a cartoon series in 73, a new television series in 87 and many movies on the big screen. Those series and movies inspired many youngsters to pursue a career in the fields of science, engineering, technology and cinema. Now the franchise is coming full circle with a fan based Kickstarter funded web series. Those inspired fans are attempting to complete the original 5 year mission “to boldly go where no man has gone before”, which ended after only three seasons on the air. The fan based and fan supported reincarnation is cleverly titled “Star Trek Continues” and has CBS’s consent.

The production company behind this effort, [Far From Home, LLC], is owned and operated by [Vic Mignogna], who also plays Kirk in this web series. They have already finished the first amazing 51 minute web-isode titled “Pilgrim of Eternity“. The film may seem campy, but it’s not. They are sticking to the original format and using the sets that were used in the sixties, rightfully so being this is the continuation of the mission. This new web series has some very interesting actors. One is the well-known Mythbuster [Grant Imahara], who plays the role of Mr. Sulu. The actor playing Mr. Scott is [Chris Doohan] the son of [James Doohan], who played Mr. Scott in the original Star Trek series.

There are more details and episode 1 after the break.

Table Saw Kickback Video Ends Badly

Our comments section has been pretty busy lately with talk of table saws and safety, so we decided to feature this sobering video about table saw kickback. [Tom] is a popular YouTube woodworker. He decided to do a safety video by demonstrating table saw kickback. If you haven’t guessed, [Tom] is an idiot – and he’ll tell you that himself before the video is over. There are two hacks here. One is [Tom’s] careful analysis and preparation for demonstrating kickback (which should be fail of the week fodder). The other “hack” here is the one that came breathtakingly close to happening – [Tom’s] fingers.

Kickback is one of the most common table saw accidents. The type of kickback [Tom] was attempting to demonstrate is when a board turns and catches the blade past the axle. On a table saw kickback is extremely dangerous for two reasons. First, the piece of wood being cut becomes a missile launched right back at the saw operator. We’ve seen internal injuries caused by people being hit by pieces of wood like this. Second, the saw operator’s hand, which had just been pushing the wood, is now free to slid right into the blade. This is where a SawStop style system, while expensive, can save the day.

The average 10 inch table saw blade has an edge traveling at around 103 mph, or 166 kmh. As [Tom] demonstrates in his video, it’s just not possible for a person to react fast enough to avoid injury. Please, both personal users and hackerspaces, understand general safety with all the tools you’re using, and use proper safety equipment. As for [Tom], he’s learned his lesson, and is now using a SawStop Table.
