And we loved when Ladyada proclaimed:
Having a tripod with you is not always all you need in order to take sharp, good looking pictures. Sometimes in low light conditions, your hand pressing down on the shutter trigger can make the image come out blurry.
So why not mix the power of the ESP8266 with a convenience of a shutter control? That way you could take photos while you’re chilling watching Netflix.

Fritzing is an open source free downloadable PCB design tool for hobbyists that only allows you to design and export gerbers for two-layer boards. It runs on Linux, Windows, and Mac:
I recently created my first “real” printed circuit board. By “real” I mean one that I sent out to get fabricated, not one I did at home by etching it myself. The board is for a Teensy LC, and breaks out most of the pins to screw terminals.
Once all the pieces are in place and connected up I switched to PCB view where you get to see what the actual printed circuit board will look like. […] It will output a whole bunch of files to the folder specified. Once I had this folder I made a ZIP file from it, and named it Teensy-BOB.zip and uploaded it to OSH Park.
The LED matrix is controlled by an Atmel ATMega328 microcontroller and the code to scroll text available on GitHub:
The parts list for Digi-Key is also available in that repo: BOM.csv

Matt Matz recorded a video of the surface mount components being reflowed… it’s magical when all the components snap into place at the end!
We are pleased to sponsor /r/DIYElectronics contests on reddit:
Each winner will receive a $30 gift code to be used on OSH Park!
The current contest is:
The mission here is simple: give me a clock you won’t see in a store.
Perhaps a word clock. A lava lamp water clock. An alarm clock that slaps you in the face and eats your hair (warning: audio). I don’t care.
There are no limits to parts, budget, or size. Your project can be as simple or as complex as you want.
You can use a breadboard, or you can design your own PCB. You decide for yourself whether you want to use a microcontroller. Up to you.
There will be 2 winners, one decided by a voting thread and another decided by a panel of judges.
- Each winner will get a $30 gift code to be used at OSHPark
- Plus: /u/optionsanarchist will be awarding 0.1 BTC to each winner
Star Simpson is designing PCBs with OSH Park for Forrest M. Mims III classic circuits! A crowd-funding campaign for Circuit Classics will be coming to Crowd Supply soon:
Each circuit depicts an original, traced and hand-drawn schematic created by Forrest Mims for his iconic books “Getting Started in Electronics”, and the “Engineers’ Notebook” series. Every board includes a description of how it works, in Mims’ handwriting, on the reverse side.
Alongside the schematic is the circuit itself. Paired with the components you need to build up timeless examples such as the Dual-LED Flasher, the Stepped Tone Generator, and the Bargraph Voltage Indicator, each board is carefully designed for easy assembly recreating the wonder of learning how electronics work— whether it’s your first soldering project or your fifty-thousandth.
People are asking me what font that is. It’s no font: that’s Mims’ handwriting. Exactly as in his books.
That’s right, Star. Circuits from the original “Engineer’s Notebook” were printed and illustrated using India ink on Mylar.
We leave you with this sage advice:
