I said 100, got it done with 80 lines of "Game code".Could be cleaner, the whole sketch is about double and the padal placement needs a bit of work.Adding a ball Spin or acceleration when a hit is made with the padal moving. a ball Split extra if...
10/24/2020: I gave a talk about Talker/80 on TrashTalk Live #8: The INPs and OUTs of Talker/80, A Modern Voice Synthesizer for the TRS-80. Thanks to Pete Cetinski (TrashTalk host) and Arno Puder (known for his TRS-IO) for inviting me; here is the PDF...
Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......
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...
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...
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...
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...
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...
