Making a DIY Case Out of PVC Pipes & Fittings for Electronics Projects

If you’ve ever visited Thailand, you may have noticed blue PVC pipes that are for water supplies, and usually visible since most of the time they are not placed underground. The pipes and fittings are very cheap, easy to find, and one person found out those could be used to make DIY cases for electronics projects. The two specimen above are a LoRaWAN node & gateway. The former is based on ESP07(ESP8266) module and RFM95W LoRa 868/915Mhz RF transceiver module, together with battery and sensors, while the latter is 1-channel LoRaWAN gateway or repeater, but I could not find the full details of the hardware design. I find that’s a clever idea, the design is pretty neat, and not everybody owns a 3D printer. An additional benefit is that it should be suitable for waterproof cases by adding some pipe glue to the unmovable parts, and a PVC screw cap […]

RasPad is a Tablet Kit for Raspberry Pi 3 B+ and Other Development Boards (Crowdfunding)

Many people interesting in coding and working on projects with the Raspberry Pi just likely connect the board to a monitor, USB keyboard and mouse, and to a power adapter, but if you are interested in having some more compact and portable RasPad tablet kit may be for you. The kit is compatible with Raspberry Pi boards, including the latest Raspberry Pi 3 B+, as well as other Arm/x86 Linux development boards including Tinker Board, LattePanda or BeagleBone Black. [Update: The design likely only works with RPi form factor, so if you use other boards with HDMI output, you may have to leave them out of the housing] RasPad key features: Display – 10.1″ IPS touch screen Video – HDMI port Audio – 2W speaker, audio jack Misc – 3 buttons (volume/brightness +, volume/brightness -, power), micro “USB touch” port Battery – Good for about 3 hours Power Supply – […]

EveLab 1.0 is an Advanced Breadboard Solution Designed for the Raspberry Pi

While it’s perfectly feasible to connect the Raspberry Pi board to a breadboard it can become relatively messy if your projects needs many I/Os due the wire and extra components like resistors, so “Robot In A Can” designed a circuit trainer for the University of Guelph students to wire projects with the Raspberry Pi’s (26-pin) header in a neater way, and made it durable to to endure years of use in a lab setting. The developer has now started selling the hardware, and called it EveLab 1.0. Evelabs 1.0 specifications: 2x 32×4 breadboards with markings for GPIO pins 1x “standard” breadboard 3x LEDs (pre-grounded) 3x Momentary Switch (pre-grounded) 2x Potentiometers (pre-grounded) 1x RGB LED (pre-grounded) 1x Analog to digital converter (2-inputs pre wired) 1x Light Sensor 1x Temperature Sensor The board also comes with 2 GPIO ribbon cables to connect to various Pi models, and 20 Jumper cables. The target board […]

Getting Started with TinyLIDAR Time-of-Flight Sensor on Arduino and Raspberry Pi

TinyLIDAR is an inexpensive and compact board based on STMicro VL53L0X Time-of-Flight (ToF) ranging sensor that allows you to measure distance up to 2 meters using infrared signals, and with up to 60 Hz. Contrary to most other VL53L0X boards, it also includes an STM32L0 micro-controller that takes care of most of the processing, frees up resource on your host board (e.g. Arduino UNO), and should be easier to control thanks to I2C commands. The project was successfully funded on Indiegogo by close to 600 backers, and the company contacted me to provided a sample of the board, which I have now received, and tested with Arduino (Leonardo), and Raspberry Pi (2). TinyLIDAR Unboxing I was expecting a single board, but instead I received a bubble envelop with five small zipped packages. Opening them up revealed three TinyLIDAR boards, the corresponding Grove to jumper cables, and a bracket PCB for […]

OKW Body Case is an IP65/IP67 Enclosure for Wearables & IoT Projects

You may have worked on a battery powered wearable or IoT projects, and the hardware and software are mostly ready, but you’ve yet to find a good way to package it to make it easily wearable, and protect it from the elements. OKW body case could be one way, as it can be used around your arm like a wrist watch, as a key ring attachment, clipped to your trousers or T-shirt, carried around your neck. The case has been moulded in ASA plastic with a high UV protection, includes a TPV sealing ring to ensure IP65/IP67 water & dust proofness, and is assembled with four stainless stell screws using a Torx drive. The company provides two sizes (Large: 55 x 46 x 17 mm, or Medium: 50 x 41 x 16 mm) and claims easy operation with the help of push buttons or touchscreens, although I’d assume water / dust resistance […]

ALio Proto Board Supports Through Hole, DIP, and SMD Components (Crowdfunding)

Perfboards and stripboards are very useful to design your own simple electronic boards without having to design your own board from scratch. However, you have to select through hole or DIP components, as – while possible with some efforts – such boards are not designed for SMD components. AERD, an open source electronic development startup based in Indonesia, has designed ALio prototyping boards supporting both through hole and SMD components, as well as some common connectors/accessories such as micro SD card, USB connector, and so on. Three versions of the board (basic, embedded, Arduino) are available with the following specifications & features: Fits SMD and PTH components at the same time. Double layer bus (top and bottom) Other components/headers All versions – 1.1 mm pitch pad for micro SD/SD card breakout Embedded & Arduino only – mini & micro USB pads, 1x SPI breakout Arduino only – Arduino header, one […]

Build your own Digital Scale with this DIY Kit

Electronics DIY kits are easy to find from either Arduino kits, or robotics kits, to oscilloscope kits among others. But I can’t remember ever seeing digital scale kits, maybe because I did not look for it, but that’s exactly what I found on ICstation for $27.99 with a scale that can measure weights up to 10 kilograms with a reported one gram accuracy. The DIY scale can also be pruchased on eBay for $29.99. Main items in the (Trans–CRS–162DZC) kit and features: MCU – STC MCU Limited STC89C52 8-bit (80C51 compatible) MCU in 40-pin DIP package RTC – DS1302 8-pin DIP chip + CR1220 socket and battery EEPROM – AT24C02 serial EEPROM (DIP chip) Display – LCD1602 16×2 digit display Keypad – 4×4 matrix keypad Sensors – DS18B20 one-wire temperature sensor, “C3 high precision” 10kg strain pressure sensor Boards – HX711 load cell amplifier module, printed circuit board for the MCU, […]
