Welcome everyone, time for the Gigatron Hack Chat. I'm Dan Maloney, I'll be the moderator today. I want to welcome Walter Belgers to the chat today to talk all about the Gigatron. Walter, thanks for coming on in what must be a difficult time. We were...
The following has been implemented:Allowed for communication with Claw machine mode via RS232 using the following menu structure:prog Enter into programming mode. Game play will be suspended after push button routine is finished (normal claw machine...
Cant add text from iceweasel, ok. Updates will be few between as I dont get to the computer with chrome on it much.So far I have a good start on the usb control part of the firmware, I have a working DAC code sample. The DAC I chose, ( PT8211 )...
The 6n137 worked great for isolating the serial at a ttl level, full baud rate isn't a problem. Cant say the same thing about hackaday.io when used with iceweasel.I will made a point of posting the isolator schematic (its pretty straight forward...
So, I been wrestling for quite a while with the pwm genorator trying to get rid of little glitches and bounces and ringing that came up during final assembly. The final straw was a 40mv, 5Mhz ring that caused the pwm comparitor to output a ring that...
So, I decided to build this 1 channel version of the power supply, and although I'm not directly documenting it, its research is going to be used in THIS power supply.What I did today: (its not tommorow till I'v slept)For the 1 channel supply I worked...
I've been slowly chipping away at the edges of a dilemma. I've been very comfortable using Dave Dunfield's MON09 monitor program for this project. It's a really nice full-featured monitor that works great, and took almost no effort to port to my hardware...
Here is the very simple circuit I am using for the PIC chip which converts unique protocol from the dial indicator to regular UART signals that can be read by a USB TTL adapter (serial protocol @ 5V). This will probably the first circuit I try making...
We now have a first draft for firmware for all three devices!After spending about a week playing around with the EZ430-RF2500, we finally have something to show for it! We have three build configurations in Code Composer Studio each with a first draft...
I can’t claim originality here... as I remember the XENON machine at a past TPF which had NIXIE tubes instead of the standard VFD displays. I always thought they were cool. Now that I’m designing Star Trek: The Mirror Universe; I’m thinking that I want...
10-18-2014 - I've created version 14 of the TeensyNet Board. I've added the ability to use one of the Serial Ports of the Teensy3.1 as an external debug monitor using a USB-to-TTL RS232 cable. The second I2C line has been brought out to terminalblocks...
Discussion of ‘hardware’ in this context refers to the electro mechanical components required to build Seek_r. It does not (directly) refer to the hardware requirements in terms of clock speeds, RAM space and other electronics. That comes later.The mechanical...
Making glass frit by hand is labor intensive. A machine should do it. This is perhaps the simplest machine which will do the job: In want of steel balls, cut-up lengths of rebar should work too. That steel is very hard. (If anybody can get the original...
I went ahead and purchased an Eagle license so I could do the board layout for the larger PCB size... You might be able to tell from the project logs, I've been having some glitches with these...but all should be on track now... The upgrade seemed...
