I found some nice AC/DC converters from Jameco Electronics, which are fairly high current switching ones. I got a 5V@3A one for $10. This allows me to put this in the case, and have the entire system be powered from the AC power input. No more external...
I also received a front-panel AC voltmeter. It was a bet because the specs were not very precise but for less than 8$ on eBay, it was worth a try. I like that this model seems to be "old school", based on the venerable ICL7107, so there is headroom for...
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...
UK study: http://www.foxnews.com/health/2015/08/19/e-cigarettes-5-percent-less-harmful-than-tobacco-uk-study-says/Well I missed the deadline to have a video uploaded :( there's always next year.....Sometimes life gets in the way and even amazing projects...
Now that Siggraph is over and I finished the lightstage, and my HD oculus rift modification, I can hopefully get some free time to work on things again at a decent rate.My PCB CNC has a useful box that switches the vacuum on and off and since its noisy...
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...
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...
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...
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...
We moved to a new space in Enschede. Address is now Marssteden 98, Enschede. It's very near the A35 / N18 highway and we have a lot of free parking space.
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...
