The zero-crossing and AC switching circuit is tested and working. Next test is PWM. Those 6x10K resistors are supposed to be 2x33K. Didn't have any 33K half watt resistors. Therefore circuit will be smaller.Please don't build and test a circuit like...
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...
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...
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...
Making the previous changes to the instruction also gives a few extra instructions: ST AC->[X,X] and ST AC->[X++,X++]. These are not super useful, so I decided to make a change to give me ST AC->[X++,D] instead. I can do this by...
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...
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...
Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found. E.g.:ED00 loc_ED00: ED00...
My old boards were an incredible step forward, but they had limited functionality, were not built with power/input/simplicity in mind, sometimes were unreliable, and were starting to die.The new boards have proper ground planes plus some cool new features...
Hey hey! We got linked! Thankya @dearuserhron and @Arsenijs! #All About Laptop Display Reuse #Laptop Display Things Also, this project, frankly, I forgot that I had, here, so most recent updates regarding avr-lvds-lcd and similar hacks...
One improvement I'm making to the Gigatron is to increase the instruction set. I wanted this to be 100% compatible with the original, so that means I can't really replace any instructions that anyone may use; however, there are some instructions...
The 230V Adapter has arrived and I am currently soldering it.Once done I will start testing and try to make the solution more secure.Currently I am still missing the Relais component for Operation.
Intro This log describes common mode rejection tests that I performed on the probe. I introduce the test setup and a test fixture, describe the results, and future plans. For reference, the probe's specs claim a common mode rejection ratio (CMRR)...
