Discussion on gel box and p/s design: | |||
Goals for gel box & related: | |||
# standardization; pick what we want, have everyone use it; get everyone on the same page for experimental results, etc. | |||
# safety; pick the best reagents & components for safety | |||
# Compare up front costs -vs- run rate costs | |||
--- "ease of use for hobbyist"; professional equip is meant to run 1000's of times; hobby equipment may run 100 times; different cost model. May want lower up front with higher run rate cost, if it makes sense. | |||
:: (Norman) Result of gel box are going into biz plan competition | |||
:: (Norman) standardizing the power supply to power multiple components (gel box, thermocycler, etc.) | |||
:: (Mac) http://www.ponoko.com/ - open source manufacturing | |||
:: (Jonathan) Look at discovery channel dna explorer for business target volumes and costs | |||
Reasons for building a custom supply: | |||
# (norman) wants to supply the illuminator, etc as well; peripheral support (LEDs, peltier device) | |||
# presumed lower cost? TBD. | |||
# (tito) experimenting with different voltages for those designing the gel box (however end user won't need variable voltages?) | |||
Power requirement: | |||
# [[Open_Gel_Box_2.0/Power_Supply/Typical_Setup|Norman's results]] show 60v, 90v, 120v | |||
# [[Open_Gel_Box_2.0/Power_Supply/Typical_Setup|Norman's results]] show 100mA is sufficient | |||
Why use a variable supply? Fixed supply is OK. | |||
# (Norman) fixed supply anywhere in the range 90-120 for "FAST RUN" | |||
# (Norman) fixed supply anywhere in the range 60v for "SLOW RUN" | |||
# (Tito) would like to test "better faster gels" (would need 300v) -- wait on the results on this; this will "gel system 3.0", not now | |||
:: (Jonathan) philip is building the experimenter-supply for ~300VDC variable output; coming soon | |||
:: (Jonathan) try the nixie supply for ~150V-180VDC for experimenting | |||
:: (Tito) Where can I buy a supply right now w/o any electronics construction that does this? Only found this one: http://educationalscience.com/merchant.ihtml?merchantid=4&pid=3178&step=4&passwordstatus=:passwordstatus | |||
:: (Jonathan) At $100 seems cheap. Price makes sense because of manufacturing volume. Not a lot of volume for this voltage range ~100v supply. | |||
:: (Jonathan) closest other method is to use +12V supply into off-the-shelf inverter to 120VAC then use a bridge+RC to filter to ~90VDC. | |||
What other peripherals might need to be connected? | |||
:: (Jonathan) Also see, the DIY spectrophotometer; possible "peripheral" to "gel system". | |||
http://www.rsc.org/Education/EiC/issues/2007Sept/BuildYourOwnSpectrophotometer.asp | |||
:: (Jonathan) customer wants a full set of equipment to use in the lab | |||

Discussion on gel box and p/s design: Goals for gel box & related:
--- "ease of use for hobbyist"; professional equip is meant to run 1000's of times; hobby equipment may run 100 times; different cost model. May want lower up front with higher run rate cost, if it makes sense.
Reasons for building a custom supply:
Power requirement:
Why use a variable supply? Fixed supply is OK.
What other peripherals might need to be connected?
