Self-Balancing Raleigh Chopper

 Self-balancing Raleigh Chopper

 

It isn’t a simply task to make a self balancing anything. But if you are thinking of taking on the challenge has documented his design details for this Self-Balancing Raleigh Chopper that could give you a head start.

 

“Data from the IMU is read by the Arduino Mega 1280. I use a Mega 1280 because they are a lot cheaper online than the 2560, and about the same price as an Uno. They have several hard wired serial outputs which means I can conveniently use one of these to send motor control data to the Sabertooth 2 x 25 Amp power controller, and another to send data to the serial-LCD screen. The Deadman switch and steering buttons (actually brake levers from children’s e-scooters) when pressed will connect their respective Mega pins to ground. The deadman is for safety, if you let go of it all power to the motors will stop after half a second. Digital Pin 12 is connected to an LED. This LED stays lit on startup and goes out after a few seconds when the machine is ready to be brought “level” at which point it will start to balance itself. The potentiometer in the diagram is actually on the left handlebar and is a Magura 5K potentiometer “twist-grip” throttle handle designed for electric vehicles. Turning it makes the machine lean forwards a little, and so it starts to roll forwards. Let it spring back and machine will lean backwards a little and slow down. It makes a very effective method of controlling speed (as well as simply leaning like you would on a Segway).”

The Combinator – A Comparator Combination Safe

The Combinator - A Comparator Combination Safe 

 

If you have some valuables that you need to keep safe you lock them in your safe (as the name implies). It probably has a dial that is used to dial in your secret combination. The Combinator is A Comparator Combination Safe just to spice things up a bit. You won’t find a microcontroller in this device even though it is an electronic safe, instead it uses all analog electronics to get the job done.

Shoulder Mounted Arduino Controlled Skull

Shoulder Mounted Arduino Controlled Skull

 

Steven from Rimstar.org built an interesting spooky Halloween skull to scare anyone who walks by. The video below goes through the construction details.

“Two heads on a body are scarier than one so for halloween I mounted an Arduino controlled skull on my shoulder with the electronics in a backpack and a hand controller hidden in my hand with the cable running down my sleeve. The jaw opens, the eyes light up and it makes a scary sound.

The biggest issue I ran into was getting a sound synthesis that could be done by the Arduino while still using a servo. Most sound libraries I found either conflicted with the servo library or required use of an abstraction layer.

Luckily the Arduino comes with a tone() function that uses simple PWM to make an 8-bit type sound that did the job while not conflicting the the servo library.”

Custom Center Car Light

at 12:59 am. Filed under DIY Hacks

 

Toyota Tarago shows us how he installed some LED center lights on his car. Took a bit of hacking to get them in there, a hot tip of a soldering iron was used to do some cutting through the plastic. I have often done the same but only for some small sections. I think I would have taken out the dremel for that job but it would have made a huge mess. The original strip had some defects so Toyota Tarago ends up making his own LED strip from some spare parts. The result looks great though.

Arduino Lithium Battery Charger Project

Arduino Lithium Battery Charger Project

 

Electro Labs has a new project posted, this time it’s an Arduino Lithium Battery Charger. With Lithium batteries you can’t just stick a trickle charge on the battery and call it done with a lot of older battery chemistries. There is quite a lot of technology packed into the design to get the job done and lots of room for user customization.

“The lithium battery charger circuit is designed as an Arduino Shield. So the main controller of the board is Arduino. But the battery charger IC on the board,LT1510, can also work alone. R3 and R4 sets the charge cut-off voltage, R2 ,R24 and C5 adjusts the charge current limit. With those passive component configurations, LT1510 can charge the battery and know when to stop. But we want to build a user programmable charger. So we had to take control of these functions.”

3D Printed Car

3D Printed Car

 

Printing this car took just 44 hours our out of 44 parts. Just bolt on some electronics and wheels are you are ready to drive! Love the design but up close it doesn’t look polished like a metal vehicle but you can see that it goes together in thick levels. What will we see in the future? Instead of customizing your new car by picking a color, interior trim option and accessories are we going to be able to push and pull some of the body features? It sure does open things up for some interesting thoughts.
