It's amazing: most flavored butters are soluble in carrier fat substrates, olive oil is most known as a frying carrier, and fresh whipped butter is the best for fresh unmodified eating.Another carrier for spices not so well known, but extra popular food in Ukraine and Russia especially good with Vodka (*): is the salted "Salo" (*) to be hard real russian Ushanka Cheburashka, drink medical cocktail: medical grade/chemistry clean C2H5OH + glucose/sextrose + Saline (bidistilled water with 0.9 NaCl)

What is the advantage of a toolpost grinder? Is it have some goods for woodturning?

Run FPV Gaming company -- online gaming with real physics.

WiFi solutions looks very slow and power loosing on long handshake

Did you test other RF interfaces like Lora or BT BLE for power consumptions?Maybe NB-IoT module will be more economic (SIM holder will eat some space)?

Video required: jast play process and tiny sounds, not something hearable

You can try to modify this: https://www.instructables.com/id/Samara-Gasifier-...You need to coil heating channel in top side section, and maybe remove diaphragm, using the lowest wrap of heating pipe as hot air flow deflector (see double wall wood gasifier stoves made from cans)

Look on FORTH language first -- it is extra simple in implementation, and with AVR forth-assembler able to update flash ROM pages you can do assembly level programming on-host mixing with threaded code or some sort of bytecode for stack machine interpreter.

Good hint for opened conservations, but extremelly only for glass jars, NOT METAL

You forget about tinkering and solder cuprum wire with steel (paper clip as contact for battery for example), use aspirin as active flux, is is some stinky bubbling on solder iron, but extremelly usable in problematic cases soldering. Don't forget to extreme washing with acid neutralization and protective nitro paint on soldered surfaces

8-) Boston Dynamics table design, look like this: https://www.youtube.com/watch?v=mXI4WWhPn-U

Good choice will be have two outputs: 110 (or 220V for europe) isolated power output, and low volatage for MCU-powered control + BT module + optorelay (fan control, timer, manual controil from cellphone,..)

Add hint with any fuel (cotton balls or discs, any paper , newspaper or cheap toilet paper preferred) poured with melted candle -- cheap easy and good fire starter. Toilet paper poured by candle wax mixed with powered saltpeter can firestart in rain.

Comparing to ordinary power banks -- this thing can be very small, and VERY lightweight, and supercheap in mass production (add LED and tiny switch for more usabiility)

Next instructable request: how to make DC/DC converter embedded into used 9V battery, to power your phone via microUSB cable. You need old 9V battrey, unpack it, make tiny PCB with effective impulse IC PWM controller and input/output capacitors (what PWM IC can you recommend to use ? scheme in USB chargers can be ineffective but maximally cheap), and solder contacts from old battry, and on-board microUSB connector. In result you will get DC/DC converter looks like 9V-battery on one side (snap it to charged new battery -- this contacts will give you reliable machanical and electrical contact), and tiny USB connector on other side. It is not emergency, but helpful if you carry it in your bag and make fast charging just bye 9V battery next shop.

Does anymody knows some short range RFID markers to mark tools in hackspace ? I have some problems with tools disappearing -- all tools in house, but have a long time to find man who take it last hour ago.

I'm going to make this like kit for home beer -- components (K-type thermo sensor amplifier for long sensor and SSR relay) on mail

I do this like bootloader reflashing just now.I used SparkFun FT232RL breakout board (china clone HEX FT232R Breakout)First I try to use fast direct FT2XX bitbang, but I use Win7 x64 and got error "pthread not supported", so I was forced to use very slow (*) serial bitbang.(*) but universal: serial bitbang can be done on any RS232 or USB-Serial converter.I found that all logic volage levels on my FT232 was inverted, so I add special iverted configuration into hardware/arduino/avr/etc/avrdude.conf file:programmer id = "invdasa"; desc = "serial port banging, reset=!rts sck=!dtr mosi=!txd miso=!cts"; type = "serbb"; connection_type = serial; reset = ~7; # RTS sck = ~4; # DTR mosi = ~3; # TXD miso = ~8; # CTS;Also I rewired your conn...

Also I added this ISP programmer into hardware/arduino/avr/programmers.txt file:bitbang.name=Serial BitBangbitbang.protocol=invdasabitbang.program.tool=avrdudebitbang.program.extra_params=-P\\.\{serial.port}(note \.\\ prefix -- I have COM10 порт so avrdude can use it only with prefix)After that I restared Arduino IDE and got Serial BitBang programmer in menu.
