BICORDER sensor box

Alex Hiam created a sensor box with the LPC824 microcontroller:

BICORDER

I put this project together for the OSH Park Bring A Hack meetup at the 2016 Bay Area Maker Faire. It’s Tricorder inspired, but can’t quite sense everything, so the name “Bicorder” seemed fitting.
The project currently has:
  • 3-axis magnetometer
  • relative humidity / temperature sensor
  • infrared range finder
  • 128×32 pixel monochrome LCD
    • live plot of temperature (in Celsius)
    • live plot of relative humidity
    • live plot of magnetic field (Z-axis) in uTesla
    • compass display (using the mag X and Y)
    • distance readout in cm

The source code is on GitHub:

Alex leveraged his ARM microcontoller board:

How The Dis-integrated 6502 Came To Be — Hackaday

We loved seeing this project at Maker Faire Bay Area 2016 and #BringAHack.  Hackaday has done a great blog post about it and recorded an interview with the creator:

I made a bee line for one booth in particular at this year’s Bay Area Maker Faire; our friend [Eric Schlaepfer] had his MOnSter 6502 on display. If you missed it last week, the unveiling of a 6502 built from discrete transistors lit the Internet afire. At that point, the board was not fully operational but…

Maker Faire Bay Area 2016

MF16BA_Badge_255OSH Park is at Maker Faire Bay Area  Laen, Dan and Drew are scouring the fairgrounds to see awesome projects makers have built with purple PCBs.  Please let us know on Twitter, Facebook or Google+ if you’re here at Maker Faire, too!

unnamedWe’ll be at these evening events and hope to see you too:

We are excited to attend these two talks at Maker Faire:

Rocket Dept has terrific Learn to Solder kits in lovely purple ‘n gold, located in the main expo hall.  They debuted a new kit called Hue which is big adjustable RGB LED:

PocketNC is showing off their new FR4 Machine Shield which is made entirely from one of our PCB panels (we can do white for orders of 1,000+ sq inches).  Find them in Redwood Hall (a.k.a. Maker Pro building) next to PancakeBot:

Nick Sayer of Geppetto Electronics has brought Toast-R-Reflow controller and many other boards to Maker Faire.  He’s next to Rocket Dept. in the Main Expo hall:

Diode-Diode Logic Clock

Ted Yapo is building a very interesting clock:

The Diode Clock

A digital clock built with Diode-Diode Logic (DDL), a quirky new logic family using only common diodes and passive components.

The EAGLE design files and LTspice simulation file  are shared here on hackaday.io.

Ted created a smaller example to demonstrate diode logic gates really are:

The board is shared on OSH Park:

16-Channel I2C Relay expander

Andrew Sowa designed this notched PCB in Kicad to control a rely board via I2C:

pcb+front-full16-Channel I2C Relay expander

A recent project required me to control 48 channels of line voltage.  I knew I needed some relays and more control lines so I went on a search for something affordable.  Numato Labs had a nice 16 channel unit that was within budget and I was able to mock up a working unit by using a MCP23017 from Adafruit.

I wasn’t happy with the mess of wires and wanted something cleaner.  Using Kicad and OSH Park, I made a small form factor surface mount unit.  This reduced my supply wires and allowed me to daisy chain units for easier install.

The design files and source code are available on GitHub:

Junes-PhD has shared the board on OSH Park:
