SimplePnP is a Low-Cost, Open Source Hardware Pick-and-Place Machine (Crowdfunding)

SimplePnP OSHW Pick-and-Place Machine

If you have a small production run for your board, it may not be cost-effective to ask a factory to manufacture it for you, and assembling the boards entirely by hand will be a time-consuming process. Getting a pick-and-place machine to automate the process would save time, but even the cheaper models on Aliexpress cost several thousand dollars. Citrus CNC tries to address the cost issue with the SimplePnP open source hardware pick-and-place machine that brings the price down to several hundred dollars. SimplePnP key features and specifications: MCU – Microchip Atmega328p running GRBL firmware Motor Drivers – TMC2209 stepper for two-phase stepper motors Word Area – 300 mm (X) x 300 mm (Y) Z Travel – 23 mm Components per Hour – 750 with vision assist Component Size – As small as 0402 (1005 metric) Vacuum Heads – Single vacuum head (base model), or optional dual-head Nozzle System – Juki 5xx with tool changer capable holder Vision – Top-vision …

SwitchTrick Switching Power Supply Board Helps you Test your Breadboard Circuit

We’ve covered several power supplies for breadboards over the years including toaster breadboard power supply with variable voltage output, or the portable, battery-powered MEGO power supply that allows you to power your project on the go. The SwitchTrick is another one of those breadboard power supplies but with testing in mind, as it takes input from various sources, and with jumper selection for voltage from 1.8V to 6V allows you to easily simulate different battery voltage levels, or the test the overvoltage protection of your circuit for example. SwitchTrick key features and specifications: Step-down converter – TI TPS62160 3-17V step down-convertor adjustable from 0.9-6V out at 1A. Power Input – 3V to 17V via 5.5×2.1mm power jack for 9V battery or wall supply Micro USB connector for 5V 2-pin JSY PH connector for battery 2x large plates holes for alligator clips Power Output (selectable by a jumper) 1.8V 2.5V 3.0V (e.g. for simulating an almost depleted lithium battery) 3.3V 3.7V …

SH72 Soldering Iron Looks Similar to TS100, Sells for around $10

SH72 Soldering Iron TS100 Lookalike

TS100 is a popular soldering iron in the shape of a pen, and whose temperature is controlled by an STM32 microcontroller. Parameters such as temperature, temperature steps, sleep time and others can be setup over USB, and the soldering is powered by a standard 19V power supply often used with laptops. TS100 sells for around $50, while the more recent USB-C powered version (TS80) sells for a little over $70. But a new model that looks similar to TS100 minus the OLED display is now selling for around $10 on Banggood. SH72 soldering iron features and specifications: Temperature range – 220-400℃ Temperature control knob Available/supported tips – SH-B2/SH-BC2/SH-C4/SH-D24/SH-I/SH-K/SH-Ku (Hakko types) Power Supply 12-24V DC input up to 65 Watts via 5.5 x 2.5 mm barrel jack Modes of operation – 12V >=1.5A (18W);  16V >=2A (32W); 19V >=2.1A (40W); 24V >=2.7A (65W) Dimensions Control handle – 110 x 16 x 15mm Tip size – 115 x 5.5mm Weigh – 28 …

Moving Your Arduino Project to a Final Product: 8 Useful Tips

Arduino Project Final Product

This article was written in collaboration with Jonathan Bara from Neoden USA Using Arduino to create your own tailor-made electronics equipment is a preferred method of thousands of electronics manufacturers worldwide, big and small. Arduino projects effectively start at the software to inform the Arduino microprocessor as to what to do, and then from there, move to the prototyping stage. An Arduino prototype is typically a very rough-looking machine whose only main goal is to prove that the concept at play is functional and worthy of refinement. After this stage, thought then goes into how to create a finished product that’s efficient, properly made, and ready for mainstream use. However, it isn’t always extremely easy to know when your prototype should go to the final design stage, or if there are still some kinks to be worked out. To make this process easier, here’s a list of ten tips when it comes to moving your Arduino project from work-in-progress to …

MUSTOOL MT99 is a $14 Smartphone-shaped Digital Multimeter

About a year ago we covered MUSTOOL MT8206, an inexpensive 2-in-1 multimeter & oscilloscope, and today we noticed another product from the company on Banggood. MUSTOOL MT99 is yet another cheap digital true RMS multimeter, but what’s different is the form factor. The tool looks like a smartphone and as such is more portable than competing multimeters. MUSTOOL MT99 specifications: Display – 3.5″ EBTN LCD with 3-line for voltage, frequency and analog bar… Mesurements DC voltage – 0.5 to 600V/0.1V ±(0.8%+3); input impedance: 10M Ohm AC Voltage – 1V to 600V/0.1V ±(1.2%+5); input impedance: 10M Ohm Resistance – 1Ω-10MΩ (1.2%+3); overload protection 250V AC/DC Capacitance 0.5 uF to 1000uF/0.1uF (3.5%+8) Up tp 6000uF/1uF (4.5%+10) Overload protection 250V AC/DC Frequency – 10Hz-1000Hz (2%+10); RMS above 1V AC Automatically identify diode and continuity Maximum display value – 9999 Live/neutral wire check Data hold, automatic power off Misc Automatic shutdown Portable hanging hole Single button to start smart identification function Back flashlight Buzzer …

PT100 Resistance Temperature Detector (RTD) Probes Support Extreme Temperature Ranges

WZP-187-PT100 Temperature Probe

I’ve been playing with temperature measurements in several hardware platforms such as Texas Instruments eZ430-Chronos Watch, Sonoff SC environmental monitor, Wemos D1 board with aDHT21 temperature sensor, or more recently ANAVI Thermometer with the last three platforms based on ESP8266 WiSoC. All four devices/boards above have temperature sensors designed to measure ambient temperature with for example DHT22 having a range of -40 to +125 degrees Celsius.  I had also come across DS18B20 waterproof temperature probe to measure liquid temperature several times with a range of  -55 to 125°C. Good for most use cases, and for example you could check boiling water with the later. But I had never really thought about measuring data for much lower or much higher temperatures, and this morning I came across two “PT100” temperature probes on IC Station new arrivals feed namely WZP-187 ($4.89) and an unnamed probe ($3.42) respectively capable of -200°C to +400°C and 0°C to 800°C ranges respectively.

REFLO Air is a $200 Open Source Hardware Portable PCB Reflow Machine (Crowdfunding)

PCB Reflow Phone Magnifier

While possible, it can be challenging to solder SMD components with a soldering iron or a heat gun, and going with a reflow oven is much easier and normally yields better results. But reflow ovens are usually fairly bulky, and somewhat expensive. MagixBox’ REFLO Air PCB reflow machine is much more compact making it more portable, open source hardware, and affordably priced since the early bird pledge starts at $199 on Crowd Supply. REFLO Air specifications: Control panel with LCD segment display and buttons Heat Control 100-300°C temperature control K-type thermometer Cooling fan Power Supply-110V-220VAC Max Power – 200 Watts Dimensions – 138 x 138 x 51 mm Weight – 900 g The company also offers optional accessories for its PCB reflow machine with a 3D-printed phone holder to use the phone’s camera to magnify the reflow area, a mini vice made of aluminum, and a semi-automated XY table. The documentation and resources have not been made public right now, …
