WiSer is a USB-to-UART converter with a wireless twist. This pair of devices will let you establish a wireless serial connection between a host and a target device, which makes this ideal for remote monitoring, wireless data logging, telemetry, and various other applications. Based on...

Even if you have years working with electronics, you will still find some simple hacks that you never thought about before. Personally and to save money, when I was a student with a very limited budget I knew that my Arduino UNO can work as a USB/TTL(serial) converter. I used to remove...

Strobe provides regular flashes of light. Usually Strobes are designed using Xenon Tubes. Here is LED based simple solution that can be used as strobe for entertainment and events and also as warning signals. Project is based on PIC16F1825 micro-controller with two digit frequency...

A detailed die photos and reverse engineering of the 74181 ALU chip by Ken Shirriff: What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with...

Opto-Isolated I/O Board offers a compact & convenient way to interface industrial type inputs/outputs to your microcontroller boards, Signal transmission between circuits of different potentials and impedances etc. Specifications 4 opto-isolated inputs & 4 opto-isolated...

ams31 @ instructables.com show us how to build a DIY USB to TTL Converter using CH340G IC. Lots of USB to TTL modules are available in the market based on various chips like PL2303, FT232, CP2102 and CH340g. I have decided to use CH340g IC. Low costing clones of Arduino UNO &...

16 Channel Infra-Red remote controller is based on PIC16F73 Microcontroller from Microchip. The receiver part follows RC5 (Philips) Code Format. Tiny receiver provides 16 latch outputs or 8 Latch + 8 Momentary outputs by closing Jumper J1. All outputs are TTL and can drive Relay board...

Aaron Brady writes: We popped open the case, and there were two main ICs, a Prolific 2303 (the USB to Serial IC) and a ADM3251E (the RS232 line level convertor). I tried to desolder this with no success, but Bas stepped in, cut the leads with a craft knife and ran the iron over the...
