Sjaak @ smdprutser.nl writes: When I was in China last year I sourced a couple of small E-ink displays (GDEH0124S01) through Taobao. They were simple ones with 8 14 segment characters. After some searching on the Chinese website from the manufacturer I found the datasheet. It was by all means not complete and a lot […]
Sjaak has published a new build, the STM32/GD32F103 QFN32 breakout board: Uptill now I used 0603 sized resistors and capacitors but for this project I switched to 0402 to save a few mm on the board. I have soldered many challenging chip packages so I felt confident. The technique is the same as for bigger […]
Sjaak has posted an update on his uC controlled dummy load project we covered previously: I finally found some time to check out the UCload project. A couple of weeks ago I quickly soldered the PCB and wrote a quick’n’dirty firmware for it. The basic functionality was working, but it wouldn’t do good for the […]
Sjaak has published a new build, uC controlled dummy load: I’m mostly a digital guy, but I’m wanting to design my own power supply. If I’m wanting to test that i need a dummy load. I got inspired by the re:load (www.arachnidlabs.com/reload ). I added a microcontroller, rotary switch, external powersupply input and the obligatory […]
Raj of Embedded Lab has published new project the Basic Experimenter Board for easy prototyping of electronics circuits: Most electronics projects require some common stuff like regulated power supply, input tact switches, and output LEDs during prototyping and testing phase. Wiring these things on a breadboard for every new project could be time consuming and […]
Electro Labs’ new project the DIY prototyping board with 3.3V, 5V, 12V and -12V built in power supplies: This DIY Prototyping Board is designed to provide all the most used supply voltages that a designer will need during prototyping a circuit. The switching power supplies on the board output 3.3V, 5V, 12V and -12V rated at […]
We met the Makerblock team during our Shenzhen Maker Faire visit earlier this year. They let us know that their system is close to being finalized. It’s a mechanical prototyping platform designed to make it easy to assemble robots, linear actuators, and other mechanical devices. Now, we improved a lot on this project, Makeblock can […]
Raj made a few breadboard modules to speed up prototyping. We think it’s a great idea to have a power supply, few switches, LEDs, etc, broken out into modules. It will save you a ton of time, and space on your breadboard. Breadboards are a great tool for prototyping and testing electronics circuits. However, if […]
This application note gives PCB design tips for reducing EMI in automotive environments. A lot of the advise can be applied to any PCB layout. Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) testing is an important part of design verification for serializer/deserializer (SerDes) devices in automotive applications. EMI and EMC must be considered early in […]
Today a parcel come in with lots of goodies from MDFLY. We are prototyping a lot so every useful gadget that helps us a lot. Follow below for a look at the jumper cables, resistor kits, and pogo pins in this order.
We previously highlighted Fritzing, an open source GUI based program that allows users to document their prototypes, share them with others, show them in a presentation, and create a pcb layout for professional manufacturing. The developers have released an updated version, which contains a number of improvements including a completely new autorouter, improved footprints for […]
AkosL writes in with a prototyping tip: Try teflon insulated wires. (Or other heat/wear resistant insulation materials). Why? The insulation is very resistant compared to “common” insulator materials. Both mechanically, and heat resistant (the one right in front of me is rated to temperatures between -60°C to +200°C). You could solder just few millimeters from […]
Here’s the soldered prototype of the USB POV Toy. The first power up exploded a backwards tantalum capacitor with an impressive spark, but after that was sorted everything seems to be ok. The tiny MMA7455L accelerometer took a few tries to solder, but now we can access it with the Bus Pirate using I2C or […]
A big box of PCBs arrived earlier today. Here’s the current progress: 3 PIC USB LCD backpacks, 2 Bus Pirate v4, and a USB POV Toy. Still waiting on a couple parts, but these boards are almost done.
