For, vegetables, yeah, that’s it… vegetables.

Thats a mess, maybe even dangerous. Excellent idea though.

SSR’s get hot if they are switched rapidly, if they are run NEAR capacity (like >85%), or if they are switching highly inductive loads (compressors / fridges), and it’s ALWAYS a good idea to put a quencher on the output to prevent oscillating (one of those resistor AND capacitor jobbies). I’ve worked with SSR’s a lot at work, and inductive loads or not heat-sinking them are the only real ways to kill them.

Your next project might be to interface a smoke detector to email/sms your cellphone when your apartment catches fire. Maybe a fire suppression system you can then activate from your phone.

Or if you’re growing radishes, you can just call the fire department.
Should write good post! Looking forward to seeing the next post!

i’m actually not suggesting that this project is a fire waiting to happen, just that unchecked fires suck especially when they’re in your house.

for the detector, i’d probably just get a cheap battery powered smoke detector and take out the siren then sense the voltage that normally goes through the siren with a relay, transistor, opto, anything connected to a microcontroller (i have to say arduino, right?). the microcontroller can get an email/sms onto the internet by being hooked to a cellphone or by usb to a computer perhaps. maybe best to have whatever it is supported by a backup battery like a motorcycle battery that has enough juice to power the fire suppression system.

i’ve got no idea what a good fire suppression system would be. depends on the type of fire and the environment, I guess. a water pump? linear actuator and kidde fire extinguisher? halon gas with electronic valve?

none of this requires any particularly expensive or exotic hardware and the microcontroller firmware is pretty straight forward. the trickiest part might be for someone unfamiliar with triggering an email/sms on a computer or cellphone but if you’re proficient enough to interface a microcontroller with a computer over usb, then you can probably write an email alert in vb or perl.

ok, that quick stream of consciousness looks decidedly e.e. cummings.

i feel so bad i was like yes! if i had this it would not be veggies man! man i’m a bad person but i know i’m not alone

whole new level for hidroponic systems, btw would be nice to add some sensors / measurement:
- lumens offered by lamp system
- kw consumption of the set
- calendar addon on the frontend software, to make notes for the garden.
- A simple fotoperiod db, to make the garden controller able to grow any kind of plants.

20ga wire, non NEMA listed enclosure, mixing high voltage and low voltage in the same box.

Check! Fire starter waiting to happen. 20ga solid wire…for a 15a circuit? There’s a reason a 15a circuit REQUIRES 14ga wire!!

This enclosure is NOT listed for this use and not legal…I wouldn’t be caught dead plugging this thing in…..

I applaud your ingenuity, I cringe at your lack of care for household AC, and shudder at your disregard for safety.

@tom have done the LED thing though to do it right really need to spend some money or get real busy with a soldering iron :)

@datacrusher so me great ideas actually have a cheap kw implementation if you check out the software screenshot at the bottom. It is calculated instead of measured but should be pretty close. Will be posting on the actual box setup and the software in a little while still have some work on the software.

if growing “vegetables”….why not just bulk discharge the CO2 tank that helps them grow….fast reliable fire suppression!
