Rev 0 boards arrived today. No issues. Cap touch pads work great. Each component passed basic functional tests. Next step is to develop the display screens.
Just a quick update today...Node 0 has now been built and programmed, picture to follow shortly. It is comprised of an Arduino nano and a NRF24L01 with a SMA Antenna. This will be permanently connected and powered by the server (currently a PC).My Raspberry...
Since I made a second video mode for graphics and added more vram I used the extra ram to also upgrade the first video mode for text so its now 640x240 pixels and with a 8x8 font can display 30x80 characters in two colors per character from 16 available....
Update #4: Automated side door working (see the Part 3 video)!Top shell printed out and bonded togetherIt actually is starting to look like a Mouse Droid now :)
Class 4 - Under the hood with GDB We'll learn how to use GDB, the GNU Debugger, and see how we can harness its power for debugging and reverse engineering. We'll also dig into the internals of MicroPython and see how to combine it with Thumb assembly!...
PL/0 Completed?Brave words! Can it really be completed? There are still things I would like to add but I need to move on. The current state of play is:Recognises most PL/0 dialects.Tolerant to redundant ";"One dimensional arraysPascal stringsTo do:Would...
I finally order a proper assortment of capacitors and resistor, and was able to breadboard my Sallen-Key filter designs. The circuit with 2x gain worked as expected, with a 0 to 10V response of 70ms and no oscillation at any duty cycle either.The circuit...
So I sat down to test out the board I build, after removing the 3.3 V regulator, and discovered it was not responding to the debugger. To power it, I was using 3.3 V from the LaunchPad. The LED on my board lit up just fine but the TM4C's internal LDO...
Hi, now some news about my YATL project (tiny homemade laptop),after trying to fork bitlash script engine, then try to write a language interpreter by myself... I decided to start reusing an existing project : "RunCPM" a CP/M emulator ported to (BOOSTED)...
I finished the bottom cover of enclosureand it looks this great in 3D modelthough reality produced by my printer leaves a lot to be desired.While the printer did its job, I took soldering iron, 2 and 4mm banana plugs with some accessories and prepared...
The project idea started with the Sequoia Hack 2016 at Bangalore, India where we decided to use two the devices they were providing -Amazon Tap and Estimotes to make an indoor navigable voice controlled robot - Dobby. The plan started as using Estimotes...
Further to the previous log, the revision zero PCBs arrived today, and I have to say I'm really happy with them.As I expected, I immediately noticed a couple of things that I somehow missed during the design and checking stage, such as...
