About this project
We have began posting example projects on our website www.simplecircuitdesign.com. So far the example projects we have are:
- Make A Sound Activated Camera Trigger For Your High Speed Photography Projects
- Automatic Plant Watering Circuit IR Remote Circuit Using Parts From An Old DVD Player
- IR Receiver Using Parts From An Old DVD Player
- Automatically Power Off Your Dehumidifier (Or Window Air Conditioner) When Your Door Is Left Open
Site Visitors: Please comment on the format of our DIY SimpleCircuit examples. Even after the kickstarter campaign ends, we are going to continue posting example projects on our site to encourage our users to keep exploring! So your input on our format is very useful to us and all our viewers.
P.S. I have an old digital kitchen scale that has a strain gauge I want to use for an example project. This could be a great way to exercise the instrumentation amplifier and 12-Bit ADC. Does anyone have example project suggestions for this? Thanks in advance!
"Analog" Is Not A Dirty Word
We built SimpleCircuits because we think integrating analog circuits into your projects is much harder than it needs to be.
Electronics makes projects cooler. You're well aware of this if you have ever successfully built a circuit yourself. But right now, electronics are hard to work with. They're difficult to build, debugging is annoying, and it always seems like you never have the right part when you need it.
Development boards, Arduinos, and Arduino shields have their place, and their great at what they do, but if you want to quickly invert a signal, generate a pulse, or compare two voltages, they're overkill and end up being a distraction.
SimpleCircuits are very simple, easy to understand building blocks for circuits. Each board is completely analog and designed to behave in a predictable way. They're great for novice users who want to understand the fundamentals of circuits; and for professionals that need to quickly add circuit functionality to a project.

- Buzzer, Siren, or Chirp with built in potentiometer to adjust sound frequency
- Microphone with built in band pass filter and gain
Easy Connection Scheme
Plated through hole tabs make SimpleCircuits easy to connect to. The tabs are conveniently sized for mini-grabbers, alligator clips, nuts & bolts, or solder wires directly the the surface.
SimpleCircuits were designed to be as easy to use as possible. You don't need special equipment to make mods to your board. Their size is the perfect balance between small and not too small.
The velcro is an easy way to mount SimpleCircuits to your projects. Or do what we do and stick them to your desk to stop them from moving around when probing with one hand.
The goal is to make SimpleCircuits so easy to use that you don't need user manuals. Instructions are printed in silkscreen on the bottom side of the board in case you need a little help.
- Small Size
- Each SimpleCircuit ships with velcro
- Instructions printed on bottom side
All SimpleCircuits are OpenSource. You can download schematics and board layouts for each SimpleCircuit directly from our website. Use these files for education, when you want to make custom modifications, or want to design your own PCB from our design files.
The designs are complete and the files are ready for production! We just need your help to fund the manufacturing process. If KickStarter volume is large enough, we'll be able to hire more help and ship product faster. Your contribution you'll help to fund:
- The large initial purchase of volume components
- Custom test fixtures and tooling
- Hire for PCB assembly, testing, and design work.
- Help fund the next round of SimpleCircuits
We Have Stretch Goals!
We need your help to design wireless SimpleCircuits for people that want to make their own driveway sensors, key-fob remote controlled devices, bit bang wireless information, whatever! If we reach 100k we'll design a low cost, long range, wireless SimpleCircuit that you can add to your pledge using your personal backer page.
We Have A Great Team. What That Means For You.
When you own a SimpleCircuit, you own a piece of our design team. If you're experiencing issues, have questions on how to use it, or need a design idea, we'll be here to support you. Below are the key players behind the project:
- Roy Stevens (Right) - Head maker of "things", business owner, and new project addict. Roy has worked as a professional electronics consultant since sophomore year of college over 6 years ago. He now owns his own circuit design consulting company called Henway Technologies. Roy started SimpleCircuitDesign.com to help spread his product knowledge to hobbyists and fellow makers of "things".
- Shawn Razek (Left) - Associate maker of "things", Eagle CAD guru and engineering student at the University of Cincinnati, OH. He's currently employed at Henway Technologies ever expanding his circuit knowledge and helping design new SimpleCircuits daily.
Risks and challenges
Delivery delays are caused by out of stock parts with long lead times, equipment failure, and inadequate staff.
SimpleCircuits were strategically designed so that the parts they use share common footprints among more than one manufacturer. The idea being to cover ourselves in the instance where one manufacturer goes out of stock suddenly. As an extra layer of protection, our KickStarter goal dollar amount lets us guarantee delivery in case we have to purchase parts from more expensive distributors.
Equipment failure happens (we hope it doesn't, but it happens!). We will be able to keep production rolling during downtime with hand assembly. It's not the most efficient way to manufacture PCBs but there are no SimpleCircuit parts that can't be placed by hand. Our machines are what will keep this business alive, so preventative maintenance is a top priority.
SimpleCircuits is based in Akron, Ohio where we're within walking distance from the University of Akron's Engineering campus and 40 minutes South of Case Western Reserve University; one of the nation's top universities for electrical engineering programs. Staffing will be easy with so much talent available in our area. Interns and co-op students will play a major role in the success of SimpleCircuits and we look forward to providing an excellent environment for hand-on, real-life electrical engineering job experience.Learn about accountability on Kickstarter
