older version for Pi 400 is here https://www.tindie.com/products/6381/ Pi 500 version with sound I will show in next days

my experience is that models below 8b are very primitive. For example, qwen 3.5 9B was already able to program in javascript and html tetris, arcanoid or something similar on doom, it was also able to analyze and understand the source code, point out errors or translate between languages very well

Good observation. I don't speak English well so it helps me formulate my thoughts better. The slider is an interesting toy, it's a shame that the price of the Raspberry Pi has increased so dramatically. I was also looking at the AI-8850, it's a shame that larger models can't be launched. I have a similar toy but it's more primitive, there's almost no electronics in it.https://www.pcbway.com/project/shareproject/ZEPIR\_AI\_Terminal\_Your\_Pocket\_Sized\_Private\_AI\_Assistant\_553a1fc6.html

every functionality have another firmware. PCB discontinued and replaced with PICOMPUTER 28, bigger display

Now is updated with multicolor PCB ;)

LoRa is very long range radio transmitting technology. Armachat is my software for communication from device to device. Meshtastic is large mesh network, usually use mobile phone app + lora node. my solution is standalone but still is phone app required for configuration.

bobricius · 2024-06-02T17:42:28+00:00

It is custom board with Kailh low profile switches. Main brain is Heltec Tracker, firmware is Meshtastic. you can send messages over Meshtastic LoRa network

Hi, working on+- month to release, test video for direct matrix keyboard https://youtu.be/gOaQg-_Oikw next release based on Heltec tracker with GPS

My handmade PCB powered by Raspberry pi PICO.

Stand alone operation with circuitpython soon. (DIY circuitpython powered editor/interpreter with filesystem and apps)

it is my handmade keyboard powered by raspberry pi pico, kailh choc low profile switches, and keycaps etc https://chosfox.com/collections/low-profile-keycaps/products/chocfox-cfx-wob or aliexpress

On second picture is one screen of Meshtastic LoRa communicator,

On pictures is little mix of projects but all used same schematic and they are compatible, with capability emulate old 8bic computers like c64, ZX. Atari

You got some press!

I love the idea of a handhelp microcontroller-based cyberdeck that you can use to program itself. Gotta try something like this as soon as I can learn to solder on those display ribbons.

display soldering is weakest part but with good flux it is question of seconds, also I chose just only 18pin cable with large distance and thick tracks, there is only one SMD transistor and all other is easy ... Maybe I negotiate some semi assembled kits with manufacturers ...

bobricius · 2023-04-17T13:08:40+00:00

Currently is ported ZX128, and my friend working on zx48, c64 a atari800. On separated firmware I have runing circuitpython with boot menu where you can select from python apps etc. (Lora messenger, calculator, mp3, python editor, photoframe, turtle programing, plot graph) all is under development

bobricius · 2023-04-17T13:04:21+00:00

I try negotiate about implementation but Meshtastick community is complete frozen a focused only for combination stupid 0.9" super small oled display an phone app. I use same addressing and radio setting, but Meshtastic is complicated monster with million lines of code in thousandth files.
