Out of curiosity, I ordered the tiny ESP8266 relay switch from aliexpress.com but never knew it could be so embarrassing to find the right way to operate. The vendor said that the switching program is inbuilt and I only have to use some android phone to operate it. But despite several attempts with several Chinese …
In this Arduino project, you will build a small relay shield from stripboard. The shield can have one or two relays fitted to it. Connect the Arduino and relay shield to your PC via a USB cable. Download the PC software and use it to switch anything on and off that is attached to the …
After GSM call alarm and GSM SMS alarm as two independent modules, I introduce the Tiny GSM alarm system. The main characteristic of this new version is that this device can operate standalone or as a module for existing alarm system. In previous versions we had only the “enable” pin that armed/disarmed the system. Now, aside from that pin we can arm/disarm the system by calling …
Description The Tiny Remoteis a very compact infrared remote control with only two buttons to control an iRobot Roomba. It produces three different infrared control signals that the robot interprets as Clean, Spot and Virtual Wall/Lighthouse. The circuit is built mostly using SMD components to reduce its size, nearly to the size of a keychain and …

A while back I made a blog post about a PIC10F200 Project: The Annoy. In this project they combined the simplicity in design along with the creativeness that I always look for, into a project with no real use other than for fun. However, the project seemed a little too large and we felt we could …

Be Careful About Peak Current A note of caution: These LEDs are comparatively expensive, so I suggest putting a small resistor (1 to 10 Ohms) in series with the cathode of the LED and measuring the peak current as inferred from the IR drop using either a scope or a peak detection probe (as described elsewhere in …

The adoption of Wearable’s has been on the rise especially with the advent of smart watches and smart glasses, and a growing interest in augmented and the virtual reality space. Most watches are beginning to have some level of smartness and the everyday smart watch is becoming cheaper. For example, in the last five months, …
The TinyFPGA boards from Luke Valenty (TinyFPGA) are a series of low-cost, open-source FPGA development boards. These boards offer an inexpensive way to get an introduction to the world of FPGAs. If you have ever considered working with an FPGA before, you will know how difficult they could be especially for those new to the game. Tiny FPGA boards …

Description Tiny, pill-sized cameras are frequently used in the medical field to visualize the gastrointestinal tract, particularly areas not readily accessible by bulkier devices. Increasingly, consideration is given to using these devices in patients who cannot tolerate, or are otherwise unwilling to undergo, a conventional colonoscopy. The possibility of displacing or augmenting these methods with …
