FS: Dummy load & LM1117A driver PCBs + more.

[jib77]

Time to purge some of my extra stuff!
===============================================
2x "Torch light" IMR-26650 cells from LED-DNA $30 shipped.

Only 1 pair available.

================================================
================================================
PCBs below are $5 each ... Shipping and PP fees are $2 for your entire order
International shipping add $1 (at your own risk, sent as a letter, no tracking)
================================================

PCB for 1117 based linear driver (DDL circuit)

10 available.

Good to about 800mA, tested to 1.2A but does not have enough heat-sinking.
Keep input voltage overhead below 2V to keep power dissipation to a minimum.

parts needed to complete:
1x 1117A (ON Semi - DPAK)
2x 1 Ohm/2W Resistors (2512 size)
1x 1n4001 Diode
2x 10uF 10V capacitors(1210 or 1206 size)
1x 100Ohm Bourns 3299

This is a pic of the completed project for illustration only ... I am just selling the PCB.

=============================================

Dummy Load PCBs

10 available.

1.4" x 0.6"

parts needed to complete:
6x 1n4001 Diodes
1x 1 Ohm 2W resistor (through hole or 2512 size SMD)
1x3 Breakaway header pins (voltage selector)
1x jumper

=============================================

Battery Contact PCBs

10 available.

These have an OD of 0.70" ... roughly the same as an 18650 cell:

Wow nobody? Am I really the only one that needs this kind of stuff?

I think they are definitely nice stuff, but most people don't exactly need this things unless they were like $1 a PCB. Most people can make a dummy load of DDL driver easily with perfboard, and they would only need to spend $2 to make several. These would be nice, but I don't think people would shell out the money on custom PCBs.

Man I hate perfboard! O well so it goes.
