Laser projector experiments Gabriel Archandel 2019-10-06 | Generated animations uploaded to the projector through bluetooth, no ILDA interface was used. Clock app is semi automatic - it generates one minute video in advance, script automatically uploads the video sequence and then after the playback is finished, uploads new one. Bla bla bla Line rider was generated by tracing bitmaps from youtube video, all the scripts are available at this github repository:github.com/gabonator/Work-in-progress/tree/master/LaserAppsThese experiments were done to evaluate the performance of the projector, if it could be used for real-time applications. All experiments were designed with this in mind, so they could be easily upgraded to use any common ILDA interface.Projector protocol hacking:github.com/gabonator/Work-in-progress/tree/master/RgbLaserProjector

Gabuino: Arduino with debugging and a lot of more Gabriel Archandel 2021-12-07 | As a big fan of Arduino and rapid prototyping I was always thinking if it is possible to provide some of the features of modern programming into world of microcontrollers. With years of experience in mobile development I was frustrated with some aspects of this platform - very limited editor, no real debugging, slow flashing... By using little tricks I put together this proof of concept how a future of Arduino could look like, here are the key features:- no installation, everything is done in web browser- uses ACE editor- real plug&play - powered by WebUSB technology- toolchain on cloud (or localhost) - for offline option webassembly could be used- 300 ms from click to running application- flexible formatting of variables - using keichi's binary parser- breakpoints is the only platform specific feature, debugging in similar fashion could be done on any microcontroller with gabuino as bootloader, even on boards without real USB interface- compared to micropython or other interpreted languages running on MCU's Gabuino gives you 100% CPU performance for your applicationsWhole video is recorded in 1x speed to see the real performance of GabuinoProject:github.com/gabonator/LA104/tree/master/system/apps_featured/117_gabuino

VFD talking to LA104 over RS485 Gabriel Archandel 2020-04-13 | Motor inverter is connected to the LA104 through RS485 serial link. Application running on LA104 requests realtime information from VFD in regular intervals and displays them on screen. GD10 mini is used in water pumping system where the PID regulator measures the pressure in water tank, compares it with preset value and controls the frequency of motor appropriatelly. In this video pump is disconnected from the VFD and taken for service, so the underload error is displayed after few seconds when no current is drawn by the pump motor.Source code and project description is available here: github.com/gabonator/LA104/tree/master/system/apps_featured/74_invtvisualInvt GD10 inverter is rebranded by Slovak company Elap with name SD10
