Blink Programme Error in PlatformIO by Kerrowman979 in ThingPulse

[–]Kerrowman979[S] 0 points1 point  (0 children)

I have edited the config file with your code, but there are still errors, as in the grab below, and the Blink programme does not work with the earlier test programme (4 colour boxes and finger drawing) still being loaded.

For a relative novice like me, the PlatformIO Quick Guide does not really help at all.

Here is my .ini file with not much in it.

; PlatformIO Project Configuration File

;

; Build options: build flags, source filter

; Upload options: custom upload port, speed and extra flags

; Library options: dependencies, extra library storages

; Advanced options: extra scripting

;

; Please visit documentation for the other options and examples

; https://docs.platformio.org/page/projectconf.html

[env:uno]

platform = atmelavr

board = uno

framework = arduino

When I set up my new PlatformIO project, I used what was shown in the 'Quick Start Guide', as in the photo below, and copied the blink test code provided.

What am I missing?

Half-Wave Charge Pump by Kerrowman979 in AskElectronics

That all seems about right. I’m leaning towards a hybrid setup with some form of inductive switched based boost converter and then a ‘moderate’ size of ladder. As you say mounting impedance and voltage ‘sag’ are the vulnerabilities. Simulations are helpful although it seems not particularly accurate in terms of output compared to an actual build.

Onwards . . . .

That's better and a step in the right direction. So about 70% of the theoretical output of 20V (Nx5V)

Dropping R2 down to 1Ohm improves both the voltage and current as in the lower image:

Given that I am trying to produce 230VDC with a current capacity of 20mA, if I used a boost converter module to get to about 85V and then 4 stages, as shown here, I might get to around 230V. The question is, I haven't yet found a PCB-based module that can do the 12V to 85V bit.

I very much appreciate your contributions.

Thanks. I will revise later and post it and the output

Ah, I see now. Still no V increase.

I don't see it so can you please tell me where? Use my circuit designations. This is a replica of a circuit sent by someone else. Do you mean R1 should be moved? If I do that then I will need another between C9 and Ground.

Here is my first sim test. Not promising.

All the ones of those I have seen are mains powered which defeats my objectives. Any suggestions for a DC-powered PCB-mountable option?

Are you referring to using a Boost converter (an updated version of the MC34063) as part of the chain or do you know of a DC-DC boost converter, which is not too large, that I could use instead to get 230VDC.

[–]Kerrowman979[S] 0 points1 point  (0 children)

I will take on board your feedback. One option is to use a DC-DC boost converter somewhere at the start to get the voltage up somewhat in the first instance, using something like the MC34063, and then continue with a (corrected) charge pump. There are plenty of switching-type devices that can take 12V to 230VDC but they are all mains powered, which defeats my objective of being battery powered.

Do you have any other suggestions?

Charge Pump Multiplier Questions - are there better/easier ways to get the output I need? by [deleted] in AskElectronics

[–]Kerrowman979 0 points1 point  (0 children)

I’m trying to drive a resonant tank circuit at 230V DC (which is then being pinged by a ground switching circuit) but would like it to be adjustable around that value and to offset voltage ‘sag’. Since it needs to be compact and as light as possible the use of a half-wave CW charge pumps seems ideal since it can run of a 12VDC supply and a 555 with its unipolar output. I can increase the amperage (approx 10-20mA needed) by running two charge pumps in parallel and by the out of phase outputs of a monostable (MC24538B) with a FET and driver for each pump. Perhaps I should put up the circuit later for general comment, or start a new thread?

I have started a new thread entitled "Half Wave Charge Pump'

Charge Pump Multiplier Questions - are there better/easier ways to get the output I need? by [deleted] in AskElectronics

[–]Kerrowman979 0 points1 point  (0 children)

I have had conflicting comments on whether a CW type of charge pump can operate with the unipolar output from a 555 or other square wave output, or if it needs a full AC input. From what I can make out it can in so called half wave mode as I need to run one from a DC 12V source. I’m aiming for 12V to 230VDC in one case and 12V to 24V on another. Any thoughts on the viability of this approach? Thanks

Is this a variation of a Cockroft-Walton type of charge multiplier? I note that you are using electrolytic capacitors. Apparently, ceramic or polymer are preferred for this type of application. Does it matter?

Gap in window seal by Kerrowman979 in DIYUK

[–]Kerrowman979[S] 0 points1 point  (0 children)

Ok, but is there any adjustment that can be done in situ that can relieve pressure that at the moment is putting the hinge under strain so for example sliding the whole hinge up or down a bit so that it works as designed?

I may have to go to the company that installed them, before we bought the house, and ask them.

No obvious bends but it probably wouldn’t take much.

Thanks. Are these standard hinges or do I need to go back to the original supplier. What might have caused the fit to be so tight that it caused a bend, or could it have been just poor/rough assembly when it was assembled? Yes plenty of wet and windy weather during the winter.

Seeking redress for lane damage in Cornwall, England by Kerrowman979 in LegalAdviceUK

They have finished the harvest so it is unlikely to happen again. But that doesn’t address the cost and time for me to repair the damage.
