USB SD Card that looks like a Apple II Floppy Drive

 

If you don’t look at the scale of the things around it you might think this drive was ripped out of some vintage gear. It is actually a fully functional USB SD card reader that looks just like an Apple II Floppy Drive.

“A typical USB SD card reader is boring. Why not show your retro affiliation with a Disk II styled reader? Modeled after the iconic Apple II floppy drive from 1978, the shell is 3D printed SLA, painted beige to match the original.”

PCBs made using a Laser Cutter

PCBs made using a Laser Cutter_3

 

If you have a laser cutter and need a double sided PCB made the same day you can give this method a try. You first paint the PCB on both sides with spray paint to act as a etching resist. The laser machine is then used to blast away the pain to expose the copper in the areas that you need to etch, a quick flip will let you do the same in the reverse. After a quick etch and removing the paint you are left with a double sided board. A quick run through a drill press will let you complete the component lead holes and via holes. Of course this design favors SMD parts since you will have less holes to manually drill.

I have tried this technique in the past for a simply board but after some issues getting the front and rear to align properly I simply made the board out of perf board. I think the key to success is the jug that clamps the board in the perfect position each time. The laser cut adjustment spring is a great idea.

The Decoliner – Vehicle you can Drive from the Upper Bridge

at 9:02 am. Filed under Cool Gadgets

 

Check out the The Decoliner, (starts at 4:32) this vehicle can be driven from the Upper Bridge. It is designed to be the max height to still fit under the normal road obstructions. This amazing vehicle can be driven from the the regular lower driving position but to spice things up you simply take the steering wheel upstairs and continue cruising. I would love to see it pulled over and watch a cop walk up to the empty lower driving position!

“This 26 ft aluminum beauty features a flying bridge, complete with driving station and room for 5 passengers on the roof!”

Thermometer and Hygrometer with Analog Displays

Thermometer and Hygrometer with Analog Displays

 

 Kerry Wong built this Thermometer and Hygrometer with Analog Displays instead of the typical digital display.

 Via: Electronics Labs and Dangerous Prototypes

 ”The circuit itself is as simple as it gets. SHT21 is mounted on a breakout board and connected to the ATMega328p board via ribbon cable. The sensor is placed at some distance away from the MCU board so that the measurement is not affected by the heat dissipated by the MCU and it’s surrounding circuitry. Because SHT21 operates at 3.3V, an MCP1700 regulator is used to provide 3.3V voltage to the sensor and the MCU. The servos I used are MG90s but you can pretty much use any servos you have on hand. The servos are powered via the pre-regulated 5V power supply and are attached to digital pin 9 and 10 on the Arduino board.”

Nixie Bargraph Clock

Nixie Bargraph Clock

 

This is a cool Nixie Bargraph Clock that has an hour and minute tube, the heights of the plasma in each tube indicates the time. There are some wires wrapped around the tubes so you can easily see what time it is without estimating.  The electronics are tucked out of sight in a box out of sight so when you are admiring the clock you don’t see the modern electronics which adds a nice touch of class. There are full details on the build so you could build your own, please note that since there is a Nixie tube in the project high voltages in the range of 140 volts are present making it a dangerous project if you are not careful.

Arduino Solar Tracker

at 6:05 pm. Filed under Cool Gadgets

 

Arduino is 10 years old! In celebration we will feature a project today that uses an Arduino at the core. Solar panels are most efficient when they are pointed directly at the sun but since its position moves across the sky all day the only way to do this is with a solar tracking device. This Arduino Solar Tracker provides the tracking using LDR sensors to detect where the best position of the panel is.
