This looks awesome. For the prototyping projects out there.
 
Tired of tricky SMT pick & place? This low cost device seems quite efficient, low tech, and reliable!

Useful when you want to connect things to power.
 
Popular battery connector names. The one I was looking for was JST-XH, not JST-PH :p

You probably saw the video of these guys open up a Microwave, hook up a can and just blast all that energy around. Thought that was insane? 

Check out this crazy Coke rocket.

I have always wondered what it is like to hook up a Pi Camera module to a normal lens. This article links to an article that answers such a question.

A crop factor of 9x. Whoa!!! ? 
 
+HomoFaciens made a timelapse of the recent lunar eclipse using a Raspberry Pi and camera module together with a zoom lens. If you didn't stay up late or get up early to see the event, it's well worth watching the video for the way the inky shadow of Earth spills across the Moon - it's very eerie.

The video and accompanying project pages are available in both English and German.

Elderly People Look At Their Younger Reflections In This Beautiful Photo Series By Tom Hussey: http://digitalsynopsis.com/design/reflections-of-the-past-tom-hussey/
‘Reflections of The Past’ is an award-winning photo series by commercial advertising photographer Tom Hussey. The photographs show an elderly person looking pensively at the reflection of his/her younger self in the mirror. Hussey was inspired by a World War II veteran who said “I can’t believe I’m going to be 80. I feel like […]

Add to the long list of ways EULAs harm users: the government says Apple's software licenses mean it can be compelled to unlock a seized iPhone.
When you buy a book, the government can’t demand the publisher or bookstore turn over the notes you’ve written in the margins. But in a case in the United States District Court for the Eastern District of New York, the government is currently arguing that the way Apple licenses its software to users means that people don’t actually own their copy of code that powers their iPhones, and thus the company can be ordered to bypass the lock screen in o...

+Peter van der Walt​, any recommendation where I can find a replacement for this part? It's the rubber piece behind a camera button. It is round, about 10mm in diameter and has the number 326 embossed on the top.

Maybe mess with the silicone mixture you use to make it? (I don't know what to mix to make it more or less stiff, but it seems like it should be possible).

I think this is a pretty cool device to build with my daughter when she is a bit older. The biggest problem I can see is controlling the camera from the pi.

They serve one dish : bun bo hue. They do it very very well. The meat is plenty. The broth is fantastic. Just the right level of spiciness. The Noodle tastes fresh, just the right firmness. Very crowded on weekends popular hours. Definitely worth the wait though.

The food court and the bakery alone are already worth visiting. The grocery availability is great. Veggies are fresh, kimchi is tasty, the meat section is well stock and the fish is super. Many of the meat cuts and fish are not available at America markets. The store is also very clean. There are two problems that are mostly due to their popularity : lack of parking spots and long checkout lines. Try to avoid weekends if you can.

This location is accessible from the free way. It has plenty of parking space and the wait lines have not been bad the few times I have been here. The greeter and table service is fantastic. Everyone has an uplifting attitude and regularly checks to make sure my experience is awesome :-). The restaurant is clean, and the noise level acceptable. The food is delivered warm (not hot). This causes the Texas Skillet dish to be mediocre. The Egg Benedict was also so so. I wish the croissant has been a fluffy crunch but instead it was too soft and taste like a slice of bread. Still, it is one of the better breakfast places around. And the care I got from servers definitely made up for the food. A good spot for family brunch and lunch in this part of town.

This place changes the name from Bangkok Chef late of 2015. They change the menu as well but the chef and the service staff are the same. The quality remains similar despite the dish change. It's the best Thai food place in downtown. Super busy during lunch. It is better to order to go and sit in the chairs in the corridor in the back then to wait in line next to the kitchen full of smoke. The chef is quick. This will turn out to be faster so you can finish your lunch in time. The food is tasty. The portion is good. You get some soup on your to go as well. The curry is flavorful without being too hot. The sauce is just right. Not too thick. The fry rice is good as well. Rice is cooked and soft. Enough sauce and the meat is flavorful with just enough chewiness leave you wanting the next bite.

The price is not bad. They are very quick having 20+ people working at the same time. The quality of the outer wash is good, no clear issue. The interior wipe down and vacuum are not done well. There are still dead bug carcasses and pieces of papers on the carpet floor. They also do not open the storage box in between the passenger and driver seats. So no cleaning is done there. You should take out all your trash at the first station when the gentleman asks you what service you want since all the trash will be taken out of the carpet and put on your seats instead of being thrown away. They also pump the air for free. Only the front tires but that potentially is a miscommunication. My TPMS light is still on and the gentleman doesn't look at the sticker for the correct pressure either. I expected all four tires inflated to the correct pressure and that did not happen. I did tip him afterward for helping.
