The LM1 is in constant current mode. Around 2mA output requires a.9k resistor. There is some trial and error involved with different currents. Test accordingly. The equation "should" be: Rcol = Vref / I. Vref is the Adjust pin voltage of 1.25v and I is the desired current. The equation breaks down with higher resistances / lower currents. This sub circuit could be broken out for independent use. Do not go over 40v D or the LM1 will blow. If the voltage is always the same, the LM1 could be removed and Rcol could be set to 2mA using the formula: Rcol = Vsupply / I make colloidal silver by the half gallon. My electrodes are submerged about 5 inches in the distilled water, 1.5 inches apart, stirred with a slow turning motor, and are fed with a 9v wall wart. It takes about 5 hours to complete. Finish voltage across the silver wires is around 10v. If the solution starts turning light green with the constant slow stir or light yellow with a periodic stir (larger particle clumps), stop the process and take notes that next time should be shorter with a slightly higher finish voltage for you. The finished product shouldn t have any color and should not be cloudy beyond the Tindall effect. LM58 ased lood lectrifier (ipolar Astable Multivibrator) RF 1nF 62v+ DZL 18v RLP 1k RLIN 4k L 1 2

IN2 DSP2 DSP1 Fixed Frequency lood lectrifier (ipolar Astable Multivibrator) ONN_elect out For private, experimental, and small run educational use only. A full transistor version can handle higher voltages and get the square wave closer to the power rails. Note that this doesn t always mean a better treatment. Voltage too high can damage cells. Voltage too high can electrolysis crack water in arteries and veins and create dangerous air bubbles. A full transistor version does not use an op amp like the LM58 and may be easier for some to build. The higher voltages do not allow for the constant current colloidal silver sub circuit in the other design but can still use a fixed resistor in place of it. e sure to check parts ratings carefully when using higher voltages.

Variable frequency versions of this circuit do not work. hoose the other one for variable. If a low frequency is chosen, beware of transfection issues. Timing is determined by the 1+R2 and 2+R pairs. Symmetrical square waves: 1=2, R2=R. R1, R4, R5, and R6 (capacitor charge) should be less than R2,R (capacitor discharge). harge Path: Supply to R1 to 1 to D2 to Q2 base to Q2 emitter to ground. Discharge Path: Supply to R2 to 1 to D to Q1 collector to Q1 emitter to ground. D1 and D2 (1n4148) protect the transistor bases from excessive reverse voltage that would blow them. R5, R6, D, and D4 are used to make the square wave a proper square. R5=R1, R4=R6 Frequency math: Freq = 1 / (1.8 * R * ) Where R2=R is R and 1=2 is. If the R1 to R6 resistors are too high, there might not be enough current for the transistors to activate. In this situation, the circuit may lock up. Using the LD flashers is highly recommended. Quick Frequency Table (choices for 1, 2, R2, R): 220nF: 100k=Hz, 40k=Hz 40nF: 4k=Hz, 40k=Hz 680nF: k=hz, 60k=Hz 1uF: 22k=Hz, 220k=Hz D2 R4 2k2 D4 R6 2k2 Q2 RVout 4k Q Q1 RF1 100k D1 RF2 100k hoose this circuit for variable frequency. If a low frequency is constantly used, beware of transfection issues. 0Hz and above is generally considered much safer. Transistor astable multivibrators respond poorly to variable frequency control used by RVRate. The RF regenerative feedback resistors and Q+Q4 (quasi Darlington) are used to clean up a "bouncy" square wave that results. The trailing edge of the square wave is still rounded but is usable. An untested idea is to use a triple transistor darlington to fix the trailing edge square wave roll off. Note that RVRate tends to go from a slow frequency to the max frequency quickly. The LM58 version has a much more linear frequency control. Timing is determined by the 1+R2 and 2+R pairs with RVRate. Symmetrical square waves: 1=2, R2=R. RVRate changes the frequency but not the pulse spacing. hoose R2 and R for max freq values. hoose RVRate for the slowest frequency. R1, R4, R5, and R6 (capacitor charge) should be less than R2,R (capacitor discharge). harge Path: Supply to R1 to 1 to D2 to Q2 base to Q2 emitter to Q4 base to Q4 emitter to ground.
