There are now many competing wireless standards, each with its own advantages and disadvantages in battery power consumption, transmission distance, and applicability to different uses. Which is the best wireless standard for your application? Download this whitepaper. Competing wireless standards There are many competing wireless standards including cellular, WiFi, Bluetooth, Zigbee, LoRa and SigFox. Each [...]
Download a whitepaper for low-power design. These tips will extend your battery life. Summary Checklist for Low-Power Design With these tips, power consumption can be cut significantly. Read about one case study where we extended the battery lifetime by 500%. Wireless Transmission Checklist How much data do you need to transmit? How far? Which is [...]
Here is a great design checklist for wearable devices. When we do a design we check all of these things and more. Often we need to use our engineering judgment on the tradeoff between size, cost, testability, and manufacturability of the board. Power What size battery? What is the appropriate battery lifetime? How often do [...]
Data acquisition is the sampling of continuous real world information to generate data that can be manipulated by a computer. Acquired data can be displayed, analyzed, and stored on a computer. A PC can be used to provide data acquisition of real world information such as voltage, current, temperature, pressure, or sound. The components of [...]
What Is Signal Conditioning? Signal conditioning is the part of a data acquisition system that interfaces to a sensor. Most sensors require some type of accommodation to turn their input into a linear voltage that can be measured by a data acquisition computer. Often, the signal is too "small" and must be changed to a [...]

To give you an idea of what should be included in a design proposal, here is an example device design proposal that outlines the key deliverables and documentation items that a full proposal should address in detail. Voler Systems div. of Strawberry Tree Inc. Example Device Design Proposal Date: February 12, 2009 Proposal No.: V-XXX [...]
When we do printed circuit board (PCB) design we check all of the items in this PCB Layout Checklist and more. Some of the items in the list are general guidelines and we often need to use engineering judgment on the trade-off between the size, cost, testability, and manufacturability of the board. Note: This checklist [...]
