Raspberry Pico is out !! 4$, 2xI2S, 2xSPI etc../ Twister OS for Pi4

hi there ;-),

found by chance that a new „Raspberry Pico !! “ is out/available..

Cost is about 4$, software is micro-phyton or C/C++, has USB1.1, Dualcore ARM cortex 133mhz, looks like an ESP32-alternative..

some more technical specs->

Mikrocontroller RP2040
• 2 MB QSPI Flash-Speicher,• 256 KB RAM,• 2x 20 I/O Pinleiste (30x GPIO-Pins 3,3V),• ADC 12-Bit 500ksps,• 2x UART / 2x I2C / 2x SPI / 16x PWM
• RTC / Timer mit 4 Alarmen,• Pinabstand: 2,54 mm
• Micro-USB 1.1 für Strom und Datenübertragung

u can get it for example here-> https://www.rasppishop.de/Raspberry-Pi-Pico-RP2040-ARM-Cortex-SBC

and here´s a tutorial how getting started->https://pico.raspberrypi.org/getting-started/

by that, i´ve „discovered“ „TWISTER-OS !!„->absolutely super great (for RPI-4s)..

https://twisteros.com/

absolutely super nice + top usable, + absolutely sleeky look, it has tons of software pre-installed (Kodi,VLC-Player,Retro Pie,Steam-client etc..) and the great advantage is still the phenomenal sound (over USB to a xmos-bridge->I2S->ES9038Q2M) because of the short electronical circuits on the board (as mentioned in the article before), absolutely great and for the first time a real good OS for the Raspberry Pi-4 !! (its based on the normal Raspberry OS)

fantastic, give it a try !! 😉

another thing is that i´ve bought now a third pair of speaker (Mission 760i (not SE)) this time and will tell u then more very interesting facts on these Mission-lines (760,780)..wanted originally make a new subsite for it (/mission-speaker) for it..

by that a very interesting site is also this: https://www.hifiengine.com/

https://www.hifishark.com/ (link also in a widget on the right) is a very good adress for „used“ hifi-gear (crawler), cause this is also a „hi-fi website“ 😉 (or is intented to be 😉 )..

more to come „in this fashion“,

greets for now !! 😉

Wharfedale Diamond 9.1 vs. Mission 760i/780 ->no comparison.. / ESP32-Cam

So, first: sorry for lately not soo much posting here .. 😉

Second, and because this is also mainly a „hi-fi“-related website i´m very glad to be able to post here also some speaker-experiences..

I´ve just bought some „Wharfedale Diamond 9.1 (white)“ to compare it with my old speakers (Mission 760i) and also to „upgrade“ my hifi-gear in general..

and because this discussion „which sounds better ->Wharfedale 9.1 oder Missions (lastet Centuries 😉 ) ?“-> i have now the answer:

Absolutely no comparison !!! The missions have a so much greater „soundstage/room/hifi-sound..“with them, really „hi-fi“ has just begun 😉 ..and because there´s always a „certain philosophie“ (sound-wise) behind the speaker-manufactories i would say the „Wharfedale“-philosophie is not mine/direction ;-). (guess i have to buy some Dali Zensor, KEFs or monitor-audios next.. )

by that i´ve bought some ESP32-Cam-Board + Cam(5,99$)->will post some experiences with it later !!

many greets from here for now !! 😉
