ReflowR is a $99 SMT Reflowing Tool for Makers and Students

You can solder SMT components to your custom board by hand, but it would be much faster if you could get a reflow tool instead to “bake” your board after placing the components. ReflowR SMT reflowing tool offers just that in a small and affordable form factor. Some people have tried to use DIY solutions to bake their board, but results may vary. ReflowR has been specifically designed to heat PCB offering constant results. It supports reflow, rework, MSD bake, or rework pre-bake, and follows JEDEC reflow profiles. You can also add a WiFi extension to monitor the tool from your smartphone and set the temperature profile. Two version are available: Smart ReflowR – Compact 600W system for for makers and learners. Large ReflowR – Larger 1200W system for professionals “STEM Inspiration kits” are also offered without a ReflowR kit, but with multiple components, solder paste, a few PCBs, tweezers, […]

$46 TS100 Digital Programmable Soldering Iron is Controlled by STMicro STM32 MCU

I’m now using a $4 soldering iron which works most of the time for what I’m doing, but sometimes it does not seem to heat quite fast enough which may cause problems. I’m not soldering that often, so I did not think about getting a better one, but I’ve just come across an TS100 digital & programmable soldering iron with a OLED display showing the current temperature, and controlled by an STMicro STM32F103T8U6 micro-controller. The soldering iron also includes an accelerometer which allow the soldering iron to know when you are using it, so the temperature drops if it is inactive for over 5 minutes (sleep mode), and after 10 minutes of inactivity, the soldering iron automatically turns off. TS100 soldering iron key specifications: OLED Display USB – 1x micro USB port for configuration Temperature Range – 100 to 400 °C; 15 seconds to heat to 300 °C @ 19V; […]

iv-Robotics Brings SMT Resistors, Capacitors, LEDs to Breadboards (Crowdfunding)

Most people will prototype electronics projects using a breadboard and typical axial resistors and “legged” capacitors & LEDs. This works reasonably well but can be messy, and you need to learn resistor codes to choose the right value. To reduce the number of legs and make it easier for beginner, iv-Robotics has decided to create small boards with SMT resistors, capacitors and LEDs instead with markings to solve those small issues. The company calls those iResistor, iCapacitor and iLed components, and offers them in boxes of 50 pieces with various values. Experienced users might also like the fact this it’s easier to store compare to traditional components, but I feel this is really a good idea for education, and kids getting started with electronics. The project is now on Kickstarter, where you can get 50 pieces for $10, 4 boxes of 50 pieces for $35, 8 boxes with iResistors and […]

Meet STEMTera Smart Breadboard with Built-in Arduino Board, and LEGO Compatibility (Crowdfunding)

From time to time, you see new products on the market with an idea that – in hindsights – seems to simple and obvious that it makes you wonder why you or others had not thought about it a long time ago. Most people will use an Arduino board with a breadboard for their project, so it makes perfect sense to combine both into a single product, and that’s exactly what STEMTera has done, when they designed a breadboard containing an Arduino compatible board, supporting Arduino UNO R3 shields, and usable with LEGO bricks. STEMTera breadboard specifications: MCU (Arduino) – Microchip/Atmel ATmega328P-AU MCU @ 16 MHz with 2KB SRAM, 32KB flash, and 1KB EEPROM MCU (USB-to-TTL) – Microchip/Atmel ATmega16U2 MCU @ 16 MHz with 512 bytes SRAM, 16KB flash, and 512 bytes EEPROM Expansion Arduino MCU – 14 digital I/Os (including 6 PWM), 6x analog input; 5V I/Os; DC current […]

Espotek Labrador is s $25 5-in-1 Lab-on-a-Board with Oscilloscope, Waveform Generator, etc… (Crowdfunding)

We’ve already seen ultra cheap (and low end) electronics lab tools like DSO138 oscilloscope kit for $23, or the $5 USB123 USBee AX logic Analyzer, but EspoTek Labrador combines 5 electronics lab equipments into a single board that claims to act as an oscilloscope, a waveform generator, a variable power supply, a logic analyzer and a multimeter for just $25. EspoTek Labrador specifications and key features: MCU – Atmel ATXMEGA32A4U 8-bit AVR MCU @ 32 MHz with 32KB flash, 4KB SRAM, and 1024 bytes EEPROM Functions 2 channels oscilloscope up to 750ksps, ~100kHz bandwidth, -20 to +20 V range 2 channels waveform generator up to 1 MSPS supporting sinusoidal, square, triangular, sawtooth, and arbitrary waveforms 4.5 to 15V power supply up to 1.5W max 2 channels logic analyzer up to 3 MSPS per channels Multimeter with voltage, intensity, resistance, and capacitance functions USB – micro USB port to connect to […]

UNI-T UT353 is a $15 Lightweight Sound Level Meter

Since some of the products I review come with a fan, I checked some sound level meters a couple of years ago, but since they were a little too expensive for my limited use, I skipped for the time being. However, while browsing some promotions or new arrivals on DealExtreme, I’ve come across UNI-T UT355 “Noise Detector Decibel Noise Tester” which sells for $15.56 including shipping. UNI-T UT353 mini sound meter specifications: Noise Levels & Accuracy – 30 to 130 dB with 0.1 dB resolution, +/- 1.5 dB accuracy Sample rate – Fast: 125ms; Slow: 1 second Measurement features – MAX/MIN, Data hold, overload indication (OL) Display – 1.64″ LCD display with backlight Buttons – Power, FAST/SLOW selection, MAX/MIN/normal selection, HOLD/BL for data hold (short press) or turning on/off the backlight (long press) Power Supply – 3x AAA batteries; 5 minutes auto power off Power Consumption – Active: < 40 […]

Aeroscope is a Bluetooth 4.1 Wireless Oscilloscope Probe Using your Android Tablet or iPad for Display (Crowdfunding)

Oscilloscopes used to be rather bulky equipment, but recent full featured oscilloscopes have come down in size, and even become portable and battery operated with products such as DSO Quad. But since many of us already own Android tablets or iPads, Aeroscope wireless oscilloscope probe is quite a neat solution as it transmits images of the waveform over Bluetooth 4.1 to your tablet.
