We’re very excited that Star Simpson has now launched Circuit Classics on Crowd Supply!
Exquisite printed circuit boards that bring to life Forrest Mims’ vintage designs from “Getting Started in Electronics.”
Forrest M. Mims III is a trusted name in the electronics world for good reason: his charming and engaging texts have drawn millions of people into the world of electronics for the first time. I am bringing some of those hand-drawn circuits projects to life by creating an exquisitely designed series of finely crafted and highly detailed boards.
Our past blog posts about Star and Circuit Classics:
Buck Regulator Olympics is the current advanced contest in /r/diyelectronics on reddit:
The goal is to build a switching buck DC-DC converter from discrete components that can step down a fairly common input voltage to another common output voltage–in this case, 3.3V
- Output voltage of 3.3V.
- Minimum current of 100mA.
- Can not be a prepackaged buck regulator solution
- Must build from scratch using discrete components
- One winner be picked by a panel of judges including kentaurus712 and RTA5
- One winner will be picked by community votes
- Selection criteria:
- Cost efficiency (lowest overall BOM cost)
- Power efficiency
- Output tolerance
- Feedback loops
- error correction
- overcurrent protection
- turn-on voltage enables
- Both winners will receive $30 gift code for OSH Park
Congratulations to the winners of An Unconventional Clock contest in /r/diyelectronics on reddit!
Winner of Community vote:
With 20 votes total, this comprehensive build combines electronics, woodworking and using plexiglass to simulate Nixie tubes in a clock with a bunch of added features.
Be sure to check out Kurt’s detailed blog about the design and construction:
position an LED at the edge of a piece of acrylic that has a pattern laser-etched into its surface, and the LED lights up the pattern. Long ago I’d realized that a stack of 10 laser-etched digits with an LED to light up each digit might have the same visual charm as a Nixi Tube
Winner of Jury vote:
We appreciated the innovative idea and the finished look the project has. Moreover, the documentation was great and it looked awesome in the demo video.

We are big fans of Hackaday’s project website Hackaday.io and are proud to see over 200 projects there have used OSH Park.
Please let us know in the comments section below if there are other Hackaday.io projects that should be added to the list.

Jeff Ciesielski is developing a BOM/Component manager for KiCad:
The goal of this app is to ease the BOM management burden on designers who choose to use Kicad for their layout and schematic capture needs, allowing for faster, easier data entry, and to provide a part database for re-use in future design￼
- Self-curated component database
- Simply enter a part’s manufacturer, supplier, manufacturer PN, and supplier PN then click ‘save to datastore’. Information is keyed off of component value and footprint, so future uses can simply use the part lookup button to retrieve the information. Multiple suppliers, manufacturers, and part numbers are supported.
- Like-Part consolidation
- Everybody miskeys from time to time, this feature detects (to the best of its ability) components that are the same, but simply have mislabeled values. For example: (10K, 10k, 10 K) will be consolidated into a single value selectable by the user
- CSV Bom Export
- Exports PCBNew style component agregate BOMs as CSV. Suitable for upload to digikey/mouser/octopart/etc
- KiCad Backpropegation
- All changes can be saved back to KiCad Schematics
Eric Conner is developing
This is a dream that I have been working towards since 2012 […] I have finally found the time to complete it and have been progressing with leaps and bounds. Currently the project is 80% complete
Eric has thus far implemented:
- 64 switch inputs
- 64 lamp outputs
- 16 solenoid outputs
- 5 general illumination outputs
- 2 flipper outputs
- I/O Expansion port to add additional 16 solenoid outputs & flipper outputs
You can find design files and source code on GitHub and even contribute to the project:
eaconner has several shared projects on OSH Park including:
Alex Albino of femto.io recently launched a crowdfunding campaign on Indiegogo for the successor to the 8-bit AVR powered Femtoduino:
A tiny, powerful Arduino compatible board
- Atmel ATSAMD21E18A
- 256KB of flash
- 32KB of SRAM
- runs at 48MHz
- RGB LED
- push button
- USB Host capabilities
- interactive examples (Unity3D, Node.js & more)
