How would you like SH type power, the ability to adjust voltage all for next to nothing? Yes? Well read on!
2x R010 resistors
Difficulty level 2/10 easy enough for teenagers or adults.
Stage one, remove power connector, bend up a leg and refit.
Use solder sucker to remove solder.
Be careful there is a small track on the connector side. If it breaks just use a wire to link from the diode to the side leg.
Prise connector up when all solder has gone
bend up the end leg
Solder back onto board with remaing two legs and solder a thick wire to the bent up leg. Feed wire through 5 volt regulator hole as shown
Stage 2, cut track and solder wire to it
flip board over and with the craft knife cut through the large track shown, cut back and forth until it is cleanly cut. Check with a meter if you have one
Scrape off some of the green stuff and tin the track with some solder. Now solder the wire to the track
Stage 3, add two resistors to double the current trip point
Identify the two resistors R010 in the centre of this photo. Add extra solder either end as shown.
Now solder your new R010 resistors (size 2512) directly on top.
Use a standard C7024 power supply for the untouched connector (this powers the computer)
Use a 0-15V 20-30 Amp power supply for the modified connector (this goes to the power section)
