For filament we can use DC or AC voltage but AC has superiority over DC. If the filament is driven with a DC voltage there will be a voltage gradient across its length. This means the end of the display with the more positive filament voltage will have...
The address thing of the past few logs is... cool-that-it's-possible. If you don't recall from a while-back, the idea was to use a *default* address-location to use as a jumping-point to all other address-locations. A bit simplified, I'd write to address...
Desk-top oscilloscopes are very common in engineering labs. They are the first aid help devices when wave-forms need to be viewed and analyzed. Taking reads from an AC powered equipment with oscilloscopes may create a low impedance short between an o-scope...
A shipment of 80 timers arrived last week. 5 timers had broken screens. It looks customs may have gone to town on the box poorly re wrapping the PCBs afterwards. I will send them back to the factory for replacement down the track.
Some audio adapters use AC coupling (i.e. an output capacitor), while others work down to DC. The difference for audio is subtle, but for a vector display, it's huge. Here's an illustration using a DC-coupled adapter and the AC/DC switches...
Another training session was underway where students had to make an application using MIT App Inventor. The interactive app would allow the user to control electrical appliances remotely. The control signals are sent via Bluetooth and are received by...
I decided to use a Mark Aikens' VGA Board in my homebrew project (https://github.com/markadev/AppleII-VGA) to simplify (a lot) the video generation circuit proposed by Wozniak to generate NTSC video and also have VGA output.The...
In my previous project log, I wanted to send the calibration factor and the expected value directly to the teensy. I found it was easier to just calculate the conversion factor directly and send that value over. This saves some calculations and makes...
As I want to control the power been consumed by the heater to limit to the surplus power produced by the solar system and minimize RF noise im using the zero crossing switching of the Triac. So I will attempt to control the power by using burst mode...
As previously reported, the 7.11A ROM didn't work properly with the Re-UD-80 because of the video sync signal configuration. The 5.21E ROM used one pin for both horizontal and vertical sync, the 7.11A ROM used two pins. The board can be modified to work...
Just released Visuino 7_8_2_226https://www.visuino.com Significantly reduced memory usage by the generated code ( Up to 80% less memory usage! )Added ESP32 Servo supportAdded support for I2C address scramblersAdded support for Heltec ESP32...
1. Toolchain not found After stepping away few days far from my PC for family reason, I resumed my activities on the Tsykuyomi project.So I started by reading the https://github.com/WHhkwong/SIPI_Bear_playback code and looking for a SNC7001A Toolchain/SDK...
