Free Stuff - March 2023
The March recipient for the Great Scott Gadgets Free Stuff Program is Jan. Jan is the author and maintainer of RadioLib, an open-source library for embedded devices controlling various wireless radio modules like SX1276, CC1101 or RF69.
We are sending Jan a HackRF One to aid in the development of RadioLib. Until now, Jan has been doing development using an RTL dongle. The lack of TX ability, and other issues, have made the dongle a bit less than practical. We hope the HackRF One helps, and we look forward to watching this project continue to evolve!

И снова модернизация блока питания Dazheng PS-305D
Спустя 10 лет после публикации первой статьи по доработке лабораторного блока питания Dazheng PS-305D (известного так же как Ya Xun Ps-305d и Yizhan PS-305D, а так же, наверняка, и под другими именами), пришлось снова заняться этим аппаратом. У китайского ЛБП обнаружилась проблема с переменными резисторами, которые начали “шуршать”, от чего выставляемые значения тока и напряжения начали “скакать”. После чего резисторы были заменены на новые, модные, точные и многооборотистые с одной неназываемой китайской барахолки. С этими новыми резисторами - оригинальными, качественными и практически японскими (эти характеристики взяты из описания товара и...
Cynthion Hardware Design Update
Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/cynthion/updates/cynthion-hardware-design-update.
We’ve completed the Cynthion r0.6 design! As mentioned in previous updates we needed to modify the design to accommodate new components due to supply chain issues. In this revision additional changes were made to resolve some problems beta testers identified with both power input and power output.
Issues Found During Beta TestingPower input issues: When you plug Cynthion into a host computer, it is expected that Cynthion powers up and that the host computer will recognize that a device has been attached. Our beta testers found a couple of...
A new design
As it was teased with the March update and the December blog post of last year, there is a community website redesign being worked on. Launched at beta.pine64.org we’re proud to give a very early insight of what the redesign currently looks like.
PineTab-V and PineTab2 launch
The PineTab2 and PineTab-V pre-orders begin on April 13th. Both tablets feature a 1200x800 10.1” IPS LCD panel with wide viewing angles, a sturdy metal metal chassis, two USB-C ports (1x USB 3.0, 1x USB 2.0 with charging), a digital video out port, a front 2MPx and rear 5MPx camera as well as a 6000mAh battery.
Packetry: Building a High Performance Protocol Analysis Tool
https://www.youtube-nocookie.com/embed/ySVuYXfH78U
In a previous update, we introduced our work on Packetry, our new front-end software for using Cynthion to capture and analyze USB traffic on the wire. In this update, we’re going to talk a bit more about the design of that software and explain some of the work we’re doing to make it as fast and easy to use as possible.
The Need for SpeedOne of the most exciting features of Cynthion is its ability to serve as a protocol analyzer, letting you intercept and capture USB traffic on the wire, in the field, from real devices.
Fully benefiting from this feature...
March Update: Tablet Bonanza!
We end the first quarter of the year with news that Star64 will be available for purchase on April 4th and that the PineTab2 and PineTab-V(ery good!) will launch the following week on April 11th. In this month’s update we also cover PineNote development (I know many of you have been waiting for this) and discuss how software on the device has really taken off in recent months. Finally, CounterPillow - a key RK3566 community developer - sets the expectations for the PineTab2 with some real-life performance examples. Strap on your unicorn horns because there’s much ground to cover this...
