No problem, really.
No problem, really.
I am buying electronic stuff from AliExpress – due to the ******* custom policy of EU it is a much cheaper than buying from Adafruit, Sparkfun etc. Unfortunatelly. There is a lot of total crap, but also a lot of great stuff too. I am diving into AliExpress three times a week, and I found many pieces “I really have to build”. So I decided to share these tips with you and made a new web called Alitronik.
There are three tips per day at Alitronik, and each sunday is “a Funday” – a day for tips with something in common. For example – the last one is dedicated to solar power, energy metering, weather stations and lasers. Previous week was in the sign of Raspberry Pi cases, tools, robots and construction of 8085-based mini PC.
A “two hour weekend project”.
A computer running BASIC, generating composite video and reading PS/2 keyboard input using a single ATmega microcontroller. A computer running the TinyBASIC programming language on an ATmega 1284P microcontroller as well as generating composite video signals and reading PS/2 keyboard input. The computer is easy to assemble at home as all components are through-hole. You can buy ready made PCB. System features include:
… is not a car, but ARM “Bare Metal Widget”. It features:
Yes, yes, “AVR + BASIC again”… Single Chip AVR BASIC Computer is a computer running the BASIC programming language, generating composite video and reading PS/2 keyboard input using a single AVR ATmega1284P (DIL40). There is no storage device, but it shouldn’t be a big problem. Cheap PCB you can order via DirtyPCBs.
It looks like CP/M on ATmega88 – and it really is! Take your Mega48, 88 or 168, connect SD card and RAM, and voila! Really simple, but functional. Someone care to rework it for an Arduino? 🙂
Not yet, but almost… 🙂
And for those which wants emulated C64: Did you tried the CommodorePi? A C64 emulator for RasPi, with HDMI, Ethernet etc.
AVR-CDC is low speed USB CDC (Communication Device Class) soft device, suitable for “a poor man’s FTDI replacement”. Its firmware is suitable even for ATtiny45. It can handle 1200-4800 Baud using internal oscillator on ATtiny45, but with ATtiny2313 or ATmegas can handle up to 38k.
