Father-Daughter Makers

Our friend Brian Schmalz (creator of the EBB) and his daughter Deanna are featured on the Minneapolis St. Paul Mini Maker Faire site.

Deanna was our youngest presenter at the 2015 faire – she discussed the learn-to-solder board that she designed and uses to teach her elementary school classmates. At this year’s faire, she will show you how to solder with her specially-designed board.

Deanna will be teaching soldering and Brian will be talking about chipKIT at the mini Maker Faire, which is May 14 at the Minnesota State Fairgrounds.

    

Circuit Classics

We’re very excited about the Circuit Classics PCBs and kits that Star Simpson is making based on Forrest Mims designs.

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.

They look like a fantastic way to learn electronics. You can order them through her Crowd Supply campaign now.

    

2016 Hackaday Prize

 

We are once again excited to be helping judge the Hackaday Prize.

Now in its third year, the Hackaday Prize challenges the international community of designers and makers to address issues facing humanity through technology.

This year the prize is divided into five separate 5-week design challenges. The first one, Design Your Concept is ending on April 25th. It will be followed by Anything Goes, Citizen Scientist, Automation, and finally Assistive technologies, which ends on October 3rd.

20 projects will be chosen from each of the 5 rounds, and awarded $1000 per project. At the end of all 5 rounds, 100 projects in total will advance to the finals where 5 top prizes will be awarded: $150k, $25k, $10k, $10k and $5k. In addition the 1st place project will win a residency in the Supplyframe Design lab to develop their project further.

You can see the entries so far on hackaday.io. You can also head to a hackaday meetup in your community. We’ll be at the San Jose meetup on April 23rd, and hope to see you there!

    

From the mailbag: XL741 in the classroom

I just wanted to let you know that I am using your XL741 kit in my Electronics 2 class lab. It is a high quality kit and I thank you for putting it together. We build the 741 in stages, make measurements, adjust offsets, etc. It is a great vehicle to teach the analog building blocks. A student of mine (now graduated) and I wrote four lab exercises for it and they are being used now for the second time. We also just got to share them with several EE teachers who were also very enthusiastic about the idea.

We love to hear about how our kits get used!

    

Dr. Nim Prototypes

Dr. Nim was made by John Godfrey, the same person who designed the original Digi-Comp II. His grandson, Andrew Beck, has the Dr. Nim prototypes and recently shared pictures and video of them via twitter.

 

Andrew says,

Here’s a video showing the first two Dr. Nim prototypes, made by hand in the 1960s

The second prototype still works, and he shows off how the mechanism works in the video, along with pointing out some of the differences between the two prototypes.

The earlier prototype has switches that look very similar to the ones in the Digi-Comp II.

The second prototype is very close to the production version, which we blogged about some time ago, and can be seen below.

Thank you, Andrew, for sharing this bit of history!
