Old Electronic Restoration

at 1:00 pm. Filed under Crazy Hacks

 

If you enjoy repairing electronic equipment have a look at bandersentv youtube channel. He finds all sorts of old tube TVs and radios, strips them down to nothing and upgrades them changing out old caps, resistors that have drifted in value and rebuilds tons of other components. This video is just a taste of his videos. If you think that some of the cheap Chinese electronics is scary when you open the hood watch some of the videos where you can see lots of simply point to point wiring of high voltage parts, a few good bumps and I am thinking you will get a nice short to the case!

This is an interesting phenomenon. Watch the video above to see the Spinning Tube Effect and see the reason it works below.

Sydney Mini Maker Faire

at 10:15 am. Filed under Cool Gadgets, Crazy Hacks, DIY Hacks, Electronic Hacks

 

Dave from the EEVblog checks out the Sydney Mini Maker Faire which was held at the power house museum. Quite a few 3D printers and robots driving around.

At 5:45 there is a guy who does a brain wave scan of people, combines it with weather data and 3D prints a design that combines the two.

At 8:30 you can see some rockets on display outside and a demonstration of a rocket motor being fired (no rocket flights though).

At 10:23 there is an interesting home made segway driven around by a guy with an LED tie.

At 11:30 there is an impressive DIY electric vehicle. It has an interesting display that shows the individual battery voltages

Hard Disk Clock by Martin Stromer

Hard Disk Clock by Martin Stromer_3338278

 

Martin Stromer made a great looking Hard Disk Clock that is actually very easy to read and looks like a great art piece at the same time. It is based around the ATMega16 Microcontroller.

“The time is set by turning the disk and setting the read/write head to the desired time by hand. Then you push the reset button on the back (the upper one of the tree on the back) and the clock measures the position of the indicators and sets its internal electronic quartz clock accordingly. For measuring the hour I painted a binary pattern onto the backside of the disk which is illuminated by infrared LEDs and detected by matching infrared light sensors.

For detecting the set minute the read/write head is driven to the outside of the disk until it interrupts the a light barrier. The steps necessary for that are counted, the internal clock is set and the head is driven back to its previous position.

Because the current time is stored in an internally the time display can be restored if it was changed by accident. This does the middle button on the back. Pushing it will turn the disk and move the head to the correct position.”

Car Started with Capacitors?

at 12:30 am. Filed under Crazy Hacks

 

What do you guys think? Is this real or bogus. It would be very simple to fake since you could simply tie in a regular battery somewhere in circuit but with new capacitor technology I am thinking this could be real? The caps that are being used are 350F!! That is crazy but the total amount of energy available is not as much as a regular lead acid battery you would find in your car but with a small 4 cylinder  vehicle it might be an interesting solution.

Spin Stabilized Rocket

This Spin Stabilized Rocket looks really cool. The three 13mm rocket motor tubes are all angled to that it spins the rocket as it flies. You can see the rocket fly in the video below. Sure is a cool idea but I am not sure the result was optimal, but I am not sure if it is more predictable than motors installed straight in though.

How did this Nail Get in the Wood

at 1:19 am. Filed under Crazy Hacks, DIY Hacks

nail through wood

 

Before you watch the video below have a close look at the picture above and guess how this was done. There are 3 slots cut into a piece of wood, there is a real solid nail placed in the wood. Each section of wood including the outer sections are solid (just as it looks). You would not be able to remove the nail by sliding it. This was a real puzzler for me and I wouldn’t have guessed how it was done without watching the video…

Leave a guess in the comments if you think you have figured it out. You will probably need to try to not look at any other comments that may exist. I am curious how many people get it?
