Time via the serial port a lot of running pic programmer made basically all the same count of these popular possibibilities one of the “all pic programmer” other serial programmer than the stable ICSP out, vdd choice sections have to be programmed pic microcontrollers separate sockets via able programmer circuit 15v dc working with .
Allpic programmer, as its name suggests, is a PIC microcontroller programmer that includes almost all versions of PICs in 8, 18, 28 and 40 pin packages (except 16C5x series and some older versions) and also the Eeprom-e series.
A very important point to note about this programmer is that it correctly programs controllers with a built-in internal oscillator, such as 12f6XX, 16F62X,… which is not the case with many other programmers!
In older programmer models (Pony, Jdm,…) the procedure recommended by Microchip, which requires the Vdd +5V voltage to appear only after the Vpp +13V programming voltage has been established, was not followed. If the internal oscillator (IntRC I/O) and the internal reset (MCLR) were previously programmed with on, setting the PIC to programming mode and reprogramming it is only possible with this foreseen procedure!
AllPIC follows this prescribed procedure, but also has a “Vdd select” jumper for older controllers that require the reverse order of 5V and 13V voltages! The recommended software is IcProg v1.05 or later, since the 12F62x and 16F62x series controllers are supported from this version.
Jumper JP1: if connected, the Vdd (+5V) voltage will be constantly present, visible by the lighting of LED2. This mode is for all PICs without an internal oscillator (16f84, 16F87x) as well as EEPROMs.
For all new microcontrollers, JP1 needs to be removed and in this mode VDD (+5V) will only appear after the Vpp(13V) programming voltage is provided during programming. This operating mode is required for PICs 16f627, 16f628, 12F629, 12F675…
Jumper JP2: Used to select Write protection mode for EEPROM 24Cxx.
Note The programmer is not designed for 16C5x series and some other special Microchip microcontrollers.

Making practical probe for measuring instruments
I’m doing the drill bit from the syringe needle in my hand I had a lot of plastic parts that have lost their function as foam probe tip my hand I have done in terms of evaluating syringes friends who use the same method can do. easy to make practical and useful.
I’ve included it at the press idle krakodil bi-capped probe was ultimately get auspicious auspicious 🙂
Note: I cut the ends of doing it again I’ll use the drill bit
Thankyou
