This week's Weekly Roundup there's a cool digital oscilloscope and a new SBC and lots of STEM. It's everywhere! You can't get away from it!
First up on Kickstarter…
Man… I'm having a hard time saying “oscilloscope”. I've always known them to be CROs.
Anyway… It has 2 analog scope channels at up to 6 mega samples / sec, 10 digital inputs or outputs, WiFi and function generator. Nice! The grunt behind it is the PIC32MZ MCU which runs at 200MHz and is accessible vie the Arduino IDE. It's a nice board that's been kicking around for a while now. I've backed this one, so you'll be seeing a review on it when released.
Now we have a desktop plastic injection machine. It's not attracting a lot of interest, as it's a fairly niche area, quite expensive and it's generally a messy business. Anyway, we'll hopefully see the 6 grand price tag drop as it gains more interest.
Some of the drawing demos are pretty outstanding and it has a feature where it introduces some random changes in images so that it looks unique. Interesting.
Of course whack a laser in and you can engrave stuff or cut stuff up to 5mm thick.
It can also function as a pick and place machine with a resolution down to 12 microns, which isn't so crash hot for BGAs if you want to do PCB pick and place, but good enough for most SMDs.
The core module - with sequencer and mixer.
Combi - with voltage controlled feedback and oscillator.
VCO - with oscillator and filter.
and Noise generator.
Nice little STEM kit.
It can be powered from either USB, battery or PoE, which is unusual.
It's a very tempting board, except for the price. $285 Ozzie dollars is a lot and I'd have to have a very specific need for this one.
It has cool features such as copying what you write in real time… Man wish I had this at school. All those lines I had to write out by hand during detention…
The price tag is pretty good on this one too.
Now there was something on IndieGoGo that I saw… where the heck is it? Ah, there it is!
Man, everywhere it's quiet. Even Tindie is slow this week…
They claim that you can control up to 180 RGB LEDs pre strip, but be careful with this.
At full brightness, each RGB LED consumes 60mA. 2 180 LED strips will require almost 22A of juice.
The very thin power tracks usually found in LED strips won't be able to cope with that much current and don't even think of adding extra power supplies half way through the strip. Things can get a little hot with that much current floating around.
Contains all the usual stuff from a SAMD21, 20 GPIOs, 48MHz clock, but also get a LoRa module as well.
I quite like the SAMD21 MCUs, and am thinking of building a couple of boards based off it.
AdaFruit, Seeed, SparkFun, DFRobot, DigiKey
But, pssst, you can get it cheaper at MCM electronics!
Also contains a quadrature decoder. Controlled via USB, serial RC or analog inputs.
Can control motors up to 2A.
The Cheap Side
Using the AD9708 chipset which is capable of 125Msps, and an op-amp based on the AD8056, and 8 AD9280 ADCs running at 32Msps.
So, essentially it's capable of sampling at 32Msps on 8 channels at an effective 8 bit resolution.
That's pretty good, not sure where the FPGA comes into it though.
