The Pine A64 was a 64-bit Quad-Core Single Board Computer which was kickstarted at the tail end of 2015 for delivery in the middle of 2016. Costing just $15, and hailed as a “Raspberry Pi killer,” the board raised $1.7 million from 36,000 backers. It shipped to its backers to almost universally poor reviews.
Now they’re back, this time with a laptop—a 11.6-inch model for $89, or a 14-inch model for $99. Both are powered by the same 64-bit Quad-Core ARM Cortex A53 as the original Pine A64 board, but at least Pine are doing a much better job this time around of managing user expectations.

We’ve often heard (and said) if you can’t hack it, you don’t own it. We noticed that [tmbinc] has issued a call for help on his latest project: developing new firmware and an FPGA configuration for the Rigol DS1054Z and similar scopes. It isn’t close to completion, but it isn’t a pipe dream either. [tmbinc] has successfully booted Linux.
There’s plenty left to do, though. He’s loading a boot loader via JTAG and booting Linux from the USB port. Clearly, you’d want to flash all that. Linux gives him use of the USB port, the LCD, the network jack, and the front panel LEDs and buttons. However, all of the actual scope electronics, the FPGA functions, and the communications between the processor and the FPGA are all forward work.

If you’ve ever been curious if there’s a way to program microcontrollers without actually writing software, you might be interested in FlowCode. It isn’t a free product, but there is a free demo available. [Web learning] did a demo of programming a Nucleo board using the system. You can check it out below.
The product looks slick and it supports a dizzying number of processors ranging from AVR (yes, it will do Arduino), PIC, and ARM targets. However, the pricing can add up if you actually want to target all of those processors as you wind up paying for the CPU as well as components. For example, the non-commercial starter pack costs about $75 and supports a few popular processors and components like LEDs, PWM, rotary encoders, and so on.

A new single-board computer by Orange Pi has popped up for sale on AliExpress. The Orange Pi 2G-IoT is designed to compete with the Raspberry Pi Zero, and if specs are anything to go by they have done a nice job.
There are a lot of options for extra small single board computers these days and there’s a growing list at the lowest price points. Let’s call it the sub-$20 cost range (to quell the argument of shipping fees). We have seen C.H.I.P., the Raspberry Pi Foundation released the Pi Zero W (an update to the Zero line that included WiFi and Bluetooth), the already available Orange Pi Zero (which was featured in a project on Monday), and now add to that list the unfortunately named Orange Pi 2G-IoT.
The 2g-IoT is sporting an ARM Cortex-A5 32bit clocked at 1GHz with 256MB DDR2 RAM. It’s nice to see 500 MB of on-board NAND to go along with an SD card slot for larger storage. It also has a CSI camera connector, WiFi, Bluetooth, an FM Radio and GSM/GPRS with a sim card slot on the bottom. It is pin compatible with Raspberry Pi’s almost standardized GPIO layout.
All this for $10 is quite impressive to say the least, especially the addition of GSM/GPRS. Will it kill Raspberry Pi Zero W sales? We think not. While the Orange Pi’s are great little computers, they don’t have the community support that is afforded to Raspberry Pi products making for less support online when you run into a problem. That’s if you can even get the thing running in the first place. The Orange Pi’s website has not yet been updated to reflect the new release. However if you are interested in getting one for yourself right now, head over to your favorite Chinese electronics supplier.

In a recent post, I talked about using the “Blue Pill” STM32 module with the Arduino IDE. I’m not a big fan of the Arduino IDE, but I will admit it is simple to use which makes it good for simple things.
I’m not a big fan of integrated development environments (IDE), in general. I’ve used plenty of them, especially when they are tightly tied to the tool I’m trying to use at the time. But when I’m not doing anything special, I tend to just write my code in emacs. Thinking about it, I suppose I really don’t mind an IDE if it has tools that actually help me. But if it is just a text editor and launches a few commands, I can do that from emacs or another editor of my choice. The chances that your favorite IDE is going to have as much editing capability and customization as emacs are close to zero. Even if you don’t like emacs, why learn another editor if there isn’t a clear benefit in doing so?
There are ways, of course, to use other tools with the Arduino and other frameworks and I decided to start looking at them. After all, how hard can it be to build Arduino code? If you want to jump straight to the punch line, you can check out the video, below.

When you have a microcontroller or other microcomputer on the bench in front of you and it lacks the familiar keyboard and display of a modern desktop computer, what do you do when you wish to program it or otherwise issue commands? Unless you are a retro computer enthusiast who longs for a set of Altair-style toggle switches, the chances are you’ll find its serial port and attach a terminal.
Serial terminals, devices containing a screen and keyboard hooked up to send and display text from a serial port, used to be a staple of computing, but as standalone devices, they’re now rather rare. In most cases nowadays using a serial terminal will mean opening up a terminal emulator in your modern OS, Linux, Windows, or MacOS, but there is still a use for standalone hardware. [Kuldeep Singh Dhaka] certainly thinks so, because he’s making an extremely nice portable terminal with an LCD screen.
The terminal emulates a venerable DEC VT-100 terminal, but since it’s built around an STM32F105 ARM microcontroller we’re sure it could emulate other models with appropriate software. It takes either a USB or a PS/2 keyboard, so we’d expect to see it paired with a suitably tiny portable keyboard when it in use. There is no source code available for it yet since this is very much still a project in development that we’re featuring now because it is a 2017 Hackaday Prize entry, but he assures us that code will be on its way and it will be GPL licenced.
He’s even posted a video that we’ve placed below the break of the device in operation, connected to a machine running MicroPython. We’d probably turn off that beep, though.

One of the issues with getting started with any Arm-based project is picking a toolset. Some of us here just use the command line with our favorite editor, but we know that doesn’t suit many people–they want a modern IDE. But which one to choose? User [Wassim] faced this problem, evaluated six different options for STM32 and was kind enough to document his findings over on Hackaday.io.
Many of the tools are Windows-only and at least two of them are not totally free, but it is still a good list with some great observations. Of course, the choice of an IDE is a highly personal thing, but just having a good list is a great start.
