I now consider this project complete! It's very nice to be able to control the garage door from my phone as I pull into my neighborhood, and not suffer from the poor regular remote. This project has been a great learning experience for me. Both in programming...
With the parts that arrived this weekend, I now have a complete set of BOM parts for building 3 units. Here are a select few from the collection:The three inductors with a 10A current rating (SRP1270-6R8M) are much heavier than regular components.Schematic...
There is EEPROM storage in both the RTC and the Arduino chip. Various settings should be stored in this memory that survives a power cycle. Alarms can be read from their setting in the real time clock. When the alarm goes off it should set a pin high....
Now that I have regular data coming from the hotwater heater now I need to store that data in a database and make it available for retrieval.I initaly plan is to use a python scriptto subscribe to the MQTT topics and place the data into a SQLlite db...
I had some difficulties uploading a video, so I needed to lower the resolution, but still I hope this one does the job of showing that the circuit does work and runs at healthy speed, much faster than a regular TI-99/4A.
You probably use a variety of state machines every day. Some of them may be in FPGAs, some in software, and some might even use old-fashioned regular hardware. Here's some common examples:Traffic lightsCryptography machinesVending machinesGas pumpsVideo...
Check the file links for more details. Also check the cults page provided on this project's page for more instructions on how to print or laser cut the pieces. Some of the solids are optimized to fit on a regular 200x200mm printing bed. In some cases...
Finally received the characterization boards form OSH Park. Sadly the "after dark" boards they sent me were from a different customer, so I only have the regular purple prototype boards at the moment.I'll populate them and compute the permittivity...
It uses a fixed duty cycle of 80%. This is a proof of concept that I could get more power from the panels than a regular controller or direct battery connection. The array of ceramic capacitors have a large inrush current, much more...
For the last few days the birdhouse has had a nightly visitor. The little guy shows up at sundown and leaves at sunrise (a real regular :-) ). It weighs about 18 grams. Typical birds in that weight category around here include the black redstart...
Cooking lunch on phase A (regular electric stove, not induction), then brewing coffee on phase C. You can see some crosstalk to phase B (which went from 94 to 73mA RMS).Regular jumps in the voltage of all three phases. These happen multiple times...
The shape of a D10 die has no standard, it is not a platonic solid, and none of the angles are regular. Using a Stack Exchange post on the subject as inspiration (https://rpg.stackexchange.com/questions/114672/is-there-a-standard-d10-dimension-ratio)...
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
The feasibility of this keyboard hinges on the ability to use the modifier keys both as modifier keys and as regular keys. How is this going to work? The basic idea seems very simple: if you use it with another key, it's a modifier, otherwise it's a...
The tldr; on this is that I got some gel medium to mix the thermochromic pigment powder into and I like the way it's handling a lot better than mixing it into white paint. Now then.In the last set of tests, I had mixed the thermochromic powder...
