Staff Picks

This edition of Staff Picks includes everything from adaptors and bubble displays to a dehydration alert system for your plants and a dual voltage regulator.

 

MultiAdaptor from Opendous features “multiple overlapping footprints for any occasion: up to 28 pin SOIC/SO (1.27mm pitch), up to 28-pin SSOP/TSSOP (0.65mm pitch), up to four SOT23, up to three SC70, one MSOP-10 (0.5mm pitch), one SOT223, and one SOT-143. All in a 0.8″ wide DIP board. The header pins are staggered to allow press-fitting them while soldering.”

 

Chirp is a plant watering alarm – as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. Chirp uses capacitive humidity sensing as opposed to resistive humidity sensing, this means, it does not make an electric contact with the soil, avoiding electrode corrosion and soil electrolysis and resulting in better accuracy and longer battery life.”

 

Cameron Tech’s Dual Voltage Regulator comes in handy when you find yourself needing to “supply both 5v to an Arduino (without its own voltage regulator) and 3.3v to attached sensors at the same time.”

4x4x7Segment by sirkha features four HP 4-digit 7-segment bubble displays on a board designed to be mated with the Adafruit HT16K33 breakout, quickly allowing you to display four values using i2c. 

 

 

The Small VAWT Controller by Blueberry controls the current output of a small vertical axis wind turbine. The board features “a micro-controller to sense turbine RPM, input voltage, and input current, and send a PWM signal to a MC34063 buck converter, and if need be a signal to the gate of an SCR to shut down the turbine.”

Beautiful Boards #3

Whether it’s an image or unique board shape, we love it when makers add a little extra something to their boards.

Staff Picks for the Weeks of 27 July and 4 August 2014

Nsayer‘s USB Micro ISP v0.3 is a voltage-agile AVR programmer that improves on the original design of SparkFun’s Pocket AVR programmer, adding quite a bit of versatility.

  • The mini USB receptacle is replaced with the more common micro USB.
  • Added a blocking diode before the pull-up resistor. The problematic pull-up resistor to the buffer chip’s output, which provided a path from the ATTiny2313 controller’s output pin through the pull-up resistor to the target power making the Pocket AVR unsafe for 3.3 volt systems.
  • Added a 3.3 volt LDO and two-way jumper that allows you to select a target power of 5 volts, 3.3 volt power, or none.
  • The 2313 controller is powered from the 3.3 volt supply. When not supplying the target power, this allows the programmer to be agile across the entire allowable supply voltage range for every AVR chip it can program. It can program chips being powered from 1.8 volts to 5 volts.

Staff Picks for the Week of 13 July 2014

Wowza the OSH Park community is busy making wonderful projects! This week is brought to you by a single board Linux computer, the optimal Raspberry Pi power supply, and a LED display board.

Henrik’s single board ARM computer with 217-ball LFBGA that runs Linux ! 

 

NSayer‘s Pi Power, a switching power supply for the Raspberry Pi, allows you to bypass the SMT µUSB power jack in favor of a better regulated and stronger GPIO header. The Pi Power is also handy in that it won’t prevent your Raspberry Pi from fitting in the majority of containers , you have the option of connect it with a GPIO cable, and if you mount it directly you will still have access for attaching other peripherals via the GPIO header.

 

 

From temporary to permanently attached display boards, the LEDgoes is great for indoor LED displays. Ceramic resonators are used to increase scrolling speed capability, and ATMega168 chips can drive up to 20mA per digital output .
