It’s been a while since we’ve seen much action on the bristlebot front, which is too bad. So we’re happy to see [Extreme Electronics]’s take on the classic introductory “robot”: the Black Line Follower. The beauty of these things is their simplicity, so we’ll just point you to his build instructions and leave the rest…

BICORDER sensor box
Alex Hiam created a sensor box with the LPC824 microcontroller:
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.
- 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…
Monster 6502 at #BringAHack
Thanks to everyone that came to #BringAHack last night after Maker Faire Bay Area 2016! We had a fantastic time checking out everyone’s imaginative projects.
Laen loved the silk screen surprise from Windell Oskay of Evil Mad Scientist:
And we loved the Monster 6502 by Eric of TubeTime.us:
#BringAHack tonight!

Join us tonight at BJ’s from 7:00pm to 12:00am for the unofficial Maker Faire Bay Area tradition:
#BringAHack
If you are going to Maker Faire Bay Area today, then be sure checkout these talks:
Getting Started with KiCad: Open Source Electronic Design Software
Sunday, May 22, 11:00am on the Make: Electronics stage
Designing Circuit Classics
Sunday, May 22, 3:30pm at Center Stage
Also look for in the main expo hall near vintage computing area:
Also in the main expo hall nearby vintage computing area is the amazing Dis-integrated Circuits booth with the Monster 6502:
Finally, we were very excited to see this VKS board prototype with the new Octavo OSD33558 System-in-Package (“Beaglebone on a Chip”). The SiP is a 400-ball BGA containing ARM SoC, DDR RAM, power management and even 140 passives. It’s large 1.27mm ball pitch allowed Hunyue Yau to make his board using our 4-layer service.
Maker Faire Bay Area 2016
OSH 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!
We’ll be at these evening events and hope to see you too:
We are excited to attend these two talks at Maker Faire:
Getting Started with KiCad: Open Source Electronic Design Software
Sunday, May 22, 11:00am on the Make: Electronics stage
At Wayne and Layne, we use KiCad to make our printed circuit boards. We’ve been helping make KiCad better. There have been a lot of changes in the past year! From outside the project, it can be difficult to see where the project is going, so we will discuss recent and upcoming improvements.
Designing Circuit Classics
Sunday, May 22, 3:30pm at Center Stage
A walk through the process of bringing Forrest Mims’ classic drawn circuit designs to life. This talk will cover both the art of building hardware true to the vision of his books, and the practical aspects of creating a strong aesthetic and bringing graphics into the hardware world.
Here’s some of the awesome makers and projects we’ve spotted so far 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
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:
DDL Demo Board and Simple Examples
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:
16-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:
FRM16_Relay_Module_I2C_Controller
Junes-PhD has shared the board on OSH Park:

Tiny PCB line following robot
Exterme Electronics has created a tiny line following brush bot for a Scout group Electronics badge:
Black Line Follower robot – the BLF bug
cheap as possible and easy to build for kids 10-14 as part of a short electronics course
Meet Up with Hackaday this Saturday in San Mateo — Hackaday
We’ll be at Bay Area Maker Faire and we want to have a beer with you on Saturday night. Two years ago we headed off to the Bay Area Maker Faire and thought we’d invite friends and acquaintances to congregate at a bar on Saturday night. Anyone who’s been to the Faire (or been through…
