I'm not seeing an image in the first post or any kind of diagram in the link in the second post. I have no direct experience of using MOSFETs (a bit of a hole in my otherwise wide experience with electronics), so I would personally probably steer towards an integrated driver with complete overload p...
I guess that would work... worth a first try anyway (cheap and simple). The risk is that the volume will be too high for the 'phones, and there is nowhere to put attenuation without also creating cross-talk.
The risk is that a write operation (rather than a read operation) is not completed if you just unplug it hot without unmounting first. If doing a controlled shut-down, unmounting is not necessary.
Maybe, but the problem with that is I know of no headphones where the -ve wires for L and R are not commoned. You could re-wire some headphones so that L and R go to separate mono plugs, with two mono switched sockets, but also note that the volume levels driving speakers will probably not be approp...
One thing I found surprising is that the spec is tighter than I thought. For example, spec says that the minimum release voltage and current is 0.25V/0.5V and 3.5mA/7mA, actually the real values are much higher ( 12mA to release ) Nothing wrong with that. The quoted values are those where the manuf...
There are two possibilities: the speaker driver is single ended but the -ve wires are provided separately for "convenience", or the driver is double ended. Simple test: measure the resistance between the two -ve wires, if it's zero you can combine them. If it's not zero, the speaker driver is probab...
You've hit the nail on the head, and that's exactly why I don't like X10 and similar home automation systems: no status return on command sent, you just have to trust that it was actioned. The reason there is no status return is because the transmission is one way - either by radio link or through t...
Do you mean you want to access multiple RPis across a network (use VNC), or run multiple RPis using one keyboard, mouse, and screen (use a KVM switch)?
I didn't understand the difference between CHANNEL A and TERMINAL A, I believed it was the same... I think you mean you thought that circuit might be already built into the rotary encoder. No, the rotary encoder stops at the dashed line. The drawing in the data sheet isn't very good, confusing use ...
You need to understand that the RPi runs from 3.3V, which is regulated on-board from the "5V" input. The 5V pins on the GPIO are connected directly to the power input, so whatever you put in is what you get out. Because of the regulation, it doesn't matter to the RPi that the input voltage isn't exa...
I don't get what you are doing here. Are you saying you are running the Raspberry Pi binaries (which are compiled for an ARM processor core) in a virtual machine running on i86 hardware??
The datasheet for that device, as linked in the first post, shows a "suggested filter circuit". Use that, but connect to the 3.3V GPIO pin instead of 5V as shown. "Terminal A" and "Terminal B" are your inputs to the GPIO, "Terminal C" is the 0V connection. The circuit shows the required pull-ups, an...
I wanted to purchase this shift register but there are different ones with similar names. Wanted to get some clarity as which I should get. STP16CP05MTR SO-24 STP16CP05TTR TSSOP24 STP16CP05XTTR TSSOP24 exposed pad STP16CP05PTR QSOP-24 Guess a little info on what I'm planning to do with it would hel...
If that is too complex for your needs, just do the simple thing and use print statements to create a CSV file and then redirect the output from the script to a file, as suggested in another post here. That's my recommendation. Outputting to as plain a file as possible, and then using the import cap...
Your current difficulties with the 2.4A adapter may be simply the length and thin-ness of the connecting wire. It's not just a question of resistance, the longer the wire is the greater its inductance and this reacts against the peaky nature of the RPi's current demand to cause even greater instanta...
There's only one choice as far as I am concerned: 12.9" iPad Pro + Apple Pencil (if you have £850 to spare). Add the Apple Smart Keyboard for another £150 and you have a completely portable workstation. Budget a little more for top quality apps (not expensive by comparison). There are cheaper ways t...
Any ideas on how to get this to output to an Excel document (or even just a normal file but preferably straight to Excel) Creating a native Excel file will be a complex process - don't bother banging your head on that one. The good news is that virtually all spreadsheet programs can take a text for...
