I want to build a small device that will turn off power to a 120v device that is plugged into it for period of time by pushing a button. Each press of the button should increase the time off by 10 minutes and then back on again when the time expires. Please show schematics, code and wiring diagram.
Do you want it to be on Arduino??
Hi sir,
I have made a transformer less solar inverter which works perfectly fine giving sine 220 vac but not finding a suitable battery charger for my 20 number of 12 volt battery series of 32 Ah which I will charge by a series of solar panel comprising 7 * 585 watt with 50 voc. Can I charge the battery directly or need a mppt solar controller?
please give your valuable support on this.
Regards
Amit Kumar
Hi Amit,
You do not require any MPPT for your current setup, and charge the battery directly and effectively from your solar panels, however, your solar panel power far exceeds the requirement of your battery, assuming your batteries are lead acid type…so if you do not want to waste the extra available power from your solar panels, then you can use a buck converter and channelize the excess power to operate some other load like water heater etc. Otherwise you can simply use a dump regulator to burn the extra current from the solar panel and regulate the power appropriately for the battery bank.
Alternatively, the same rule can be applied if the batteries are li-ion type, for charging the batteries quickly within 4 hours of peak sunshine.
Thanks for your reply.
The solar array gives continuous power to my 1.5 ton hot& cold ac and will charge the battery through a sic diode FFSH4065D and extra power to be used by an induction heater.
According to my calculations, your panel gives 350V at 11 amp current (585/50).
Your inverter lead acid battery charging requirement is 240V @ 6 amps.
So your panel is producing 350V, 5 amp extra, that’s the only excess power it is generating.
You can use a 5 amp rated extra load with the panel…
Hi Swagatam
I recently purchased a new iPad, I noticed that it doesn’t have a 3.5 mm headphone socket like my old iPad has.
I was wondering if you have a Circuit Diagram of a Bluetooth Adapter, I would need to be able to plug a 3.5 mm set of headphones into the Bluetooth Adapter and this Bluetooth Adapter should be able to connect to my iPad.
The Bluetooth Adapter Circuit Diagram would also need to have a audio circuit, or a audio module that I could purchase.
Any information/ help would be very much appreciated.
Hi Kev,
I think the PCB module is readily available online…you can search for:
“Bluetooth 3.0 Audio Receiver Module with Stereo Output”
You can connect a 3.5mm jack at its output and use it for your application…
Thank you for your message Swagatam, I found a Bluetooth Audio Module on Aliexpress for about £0.058 so I ordered 2 of them.
Thank you for your help and information
That’s great Kev, glad you could solve it so quickly…thanks for the update!
hi…swagatam ,pls can you make a post on how to wind a ferrite toroidal core for a series pass buck converter with all the formulas and parameters just like this post on transformer? thank you…
hello, I build very high-end amps/preamps, and I would like to use switching power supplies, but I would like to have ideas for filtering the background noise as best as possible – I achieve good results, but perhaps there are simpler solutions.
Am jm.cap.i have a problem,can you pls help me with this to construct a factory vibrator controller pls pls. (electromagnetic vibrator)circuit pls
Hi Job, I can help you, please provide your circuit’s full specifications…
Hello,
I am a Ham Radio operator and have dabbled in PCB creation. I have a go box which houses my radios main power 12vdc. I have a hand mic and speakers and have a headset with both mic and earphones. I am currently switching between the two using a mechanical set of relay SPDT switches. I would like to create a PCB with a electronic solution.
Any Ideas?
Hi Tony,
I’m also a Radio Amateur, I also do various PCB Layouts from Circuit Diagrams.
You can look me up on QRZ and if I can help you, I will try as best as I can.

Hi, yes, it is possible. You can replace the mechanical relays with electronic ones by building the circuit as explained in the following article: https://www.homemade-circuits.com/12v-dc-solid-state-relay-ssr-100-amps/
The MOSFETs can be replaced with ordinary BJTs, depending on the power of the load….

Thank you so much Kishore, for your kind words!
All the best to you!
I would like to use your 10amp regulated power supply circuit using LM 317 and IRF9540,in a dual supply configuration for an audio amplifier. Shall I use LM337 and IRF540 in similar manner or shall I use the same circut to regulate the positive to common? This will necessitate using another transformer doubling the cost. What is your suggestion?
Please post your comment under a related article, I will try my best to solve your problem…
In cd 4060 circuit, when supply cut and come again, the circuit trigger, without triggering manually.
please give solution, so false triggering can be prevent by power supply failure.
When we require to on timer, then it should be operate only. So give suggestion.
Please comment under a 4060 article post, I will try to help!
