Hi to all,
I have an 9 volt DC plugpak adaptor purchased, along with and LED display
scientific calculator, back in 1972 or 73.
Makes it nearly 35 years old.

When Standby/on button is pressed, the display briefly show "ON" then
"OFF".

I have a need for a low output impedance class AB output stage. The
supply is single rail +500v. The problem is finding readily available
components to build the output stage. I think this is safely FET
territory but finding a P-channel FET is somewhat problematic. Does

Hi, I have much experience doing through hole repair work in repair
shops.  Do you think my experience there would help my likelihood of
landing a job in a board factory as an SMT machine operator?
Sincerely, Allan

I'm not able to find any good components shop that has reasonable
prices for my electronics projects.
The shop should:
- possibly be based in Europe, or offering reasonable shipping costs

I'm just getting started in electronics, and am hoping to get into
experimenting with some components as inexpensively as possible.  I've
already purchased a multimeter and a protoboard.  Now I'm looking for a
cheap source for bulk resistors, capacitors, diodes, and that sort of ...

Was suddenly contronted with the Sunday a.m.  Verizon is of little/no
help, except to say they will send a tech out on Friday the 18th.
Situation:

Someone who is familiar with this kit, would you lend some assistance?
I purchased and assembled the Mk.II version of Bob Parker's widely-praised
ESR meter kit. Assembly went swimmingly.
The first test (with ICs removed) is to see what the power draw of the board

I'm trying to supply my biped robot from a single 7.4V Li-Ion battery. I
cannot use two batteries as there are no space for them.
My problem is, that the microprocessor resets whenever I turn on the
servos (the large current draw pulls the voltage below 4V - I need 5V).

Hi, Can anyone tell me where to source a 14.4v globe online?
TIA

For those who are interested the following public meeting has been convened.
I have modified the email address below so the lady doesn't get bombarded

Anyone got any good ideas on how to directly attach a PCB to a strap
like a watch band?
I'm thinking of some sort of surface mount clip that can be attached
to the bottom of the board, and the watch band is  passed through two

I must be missing something..
I'm trying to fit some Tyco F Series connectors to RG6 cable. The tyco part
number is 5-1814826-3 which is correct for RG6/U. The data sheet says the
crimping tool must crimp down to 8.6mm across the flats. My tool crimps to
