I am building a solar wood drying kilns This requirement is simpler than it sounds as I hope to put together a system without a battery or advanced managing kit The only requirement /demand is to run 5 small fans during daylight hours It's in the tropics so not so much problem with sunlight ! The requirement for energy for is in daylight hours the hotter it is the more power is generated I am looking for real world advice as to what kit to purchase. I can assemble myself
We are looking for someone with experience in building transformer base 3 phase inverter. We are having issues where mosfets are burning. We built a buffer board using CD4011 ic to split the driver signal into 6 channels which is 3 for the high side and 3 for the low side. Then we built a transistor...where mosfets are burning. We built a buffer board using CD4011 ic to split the driver signal into 6 channels which is 3 for the high side and 3 for the low side. Then we built a transistor board and an optocoupler board that is used to feed the signal to the driver board which was designed using IR2110 ICs. This driver board is what should drive the emulator board (the mosfets) which receives the battery input and then drives the transformer. Currently the mosfets keeps getting hot a...
AMP BRIDGE . Its Home Flex 50-amp smart charger is similar in operation to its public chargers so there is no learning curve. It can be hardwired into a 240-volt circuit (typically the home’s drier circuit) or an existing 240-volt outlet. The 23-foot cable allows for more installation locations in your garage and the whole charging unit has a sleek design Sometimes you don’t need smart-charging capabilities. Instead, you might need a durable outdoor charger that can withstand tough weather conditions. AMPUSHER is ideal for home EV charging, as well as electric lawn/farm equipment, which is a growing market. There’s no app to this one, just a rugged 40-amp charger. This unit can be hardwired or plugged into an existing 240-volt outlet and the power out...

I'm looking to develop a very simple battery operated device. It is to be a circular, puck shaped device (circle 5" diameter, 1" thick). The front face contains a large button with a speaker behind it. When the button is pressed, a sound (to be determined: white noise, ocean wave, rainfall, something like this) will play for 3 minutes. After 3 minutes, the sound stops. Pressing the button again will start the sound again for 3 min, and so in. There are no other settings or controls, just this button to start the sound. The device should run on AA or 9volt batteries, (I'm open to suggestions on the pros and cons, I just want the longest life- i.e. how many 3 minute cycles can I achieve without changing the batteries? A successful prototype of this simple ...

I would like...freelancer to design a cooling system that dissipates heat from rechargeable batteries. MOFs, a metal foam material that absorbs water, wrap around lithium-ion batteries for electric vehicles. As the battery heats up, the water in the MOFs evaporates, taking the heat away and dissipating heat. The whole process is simulated by simulation software, and drawing a conclusion. Heat dissipation under different discharge power (3c and 5c) needs to be simulated. The Freelancer will be responsible for designing and implementing this system, using the evaporation principle to dissipate heat from the rechargeable battery. The Freelancer should have experience in designing cooling systems, and should be experienced with utilizing the evaporation principle. The relevant pa...

Background The future of transportation lies in EVs. Many firms are developing batteries to serve this market best. Almost all-electric and plug-in hybrid vehicles use lithium-ion batteries (LIBs). Despite much progress in battery development, some significant hurdles still exist and must be resolved. Long charging time is the main problem for EV adaptation. The US Department of Transportation reports that battery electric vehicles may be fully charged, using commonly home electric socket level 1 charger in 40–50 hours. Such a long battery charging time is a significant deterrent. Even high current level 3 DC chargers need 30 minutes to charge and require an infrastructure of specialized charging stations. Charging batteries at high currents is a hazard! ...
Hello, I need to be able to program the GPS365 ZX303 GPS MODULE communication modules to be able to make them communicate with my own system and have their battery last for more than 4 years.
...Protection against complete battery discharge (the LEDs can blink when the battery is fully discharged). Modes programming: Basic functions Magnet is quickly brought close and removed (<1 sec) - the left LED turns on. If it is quickly brought close and removed again after > 1 second after turning on, it turns off. Magnet is quickly brought close and removed (<1 sec) twice - switching from the left LED to the right LED and turning on. The XPG and Samsung diodes have different currents, which must be taken into account. Magnet is gradually brought closer and brightness is gradually increased by 20% per cycle until the magnet is removed. Minimal power consumption in standby mode to avoid self-discharge. Protection against complete battery discharge (the LEDs c...

Hi Prameswara, I noticed your profile and that you are based in Cirebon. I have a very simple task I need completed and I'm hoping you can help me. I'm in Australia and I have a dear friend in Hospital in Cirebon. He has no phone so I cannot speak with him. The job I need done is to research and purchase a cheap used cellphone + charger + internet, then simply deliver the phone to my friend. Obviously I'll send you the money to purchase the phone, cover your travel expenses too. I need this done urgently, today if possible. Please let me know if you are interested. Thank you Paul

I'm looking to build a charging device that uses the ESP32 micro-controller powered by a Li-ion (for example battery for a FireBeetle ESP32 battery port) or Li-Po battery which will be charged by a solar panel. At the same time (while charging) the ESP32 will be still working for the purposes it has been installed for (it will be working for 10 hours, between 09:00 and 19:00, so actually working only in the charging hours). Of course it should have protection when fully charged, to stop charging, etc etc. Please, only for hardware designers who have already made something like that. The other offers will be dismissed.
Hi, I have a small sailing boat which is moored in the middle of an harbour. I would like to monitor using GPRS 2G network (via Telegram) or SMS the following itens: -gps position. -temperature and humidity using the Dht11 sensor. -battery voltage. -water on the bilges. I would need also alerts for low voltage on the boat battery or high bilge water level. I have been successful in measuring the Dht11 output using WiFi and the following tutorial: However can't do it using WiFi. I'm using the TTGO T-Call V1.3 ESP32 sim800l board and dht11 sensor. Would like to continue to use the same hardware in the project. Could you please provide me a quote for the development of the code? Best Regards
