PCB is used. - LEDs go in long leg down (from the front Don't put R8 so close to R26 -- D36/R47 too close - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for a single 0.5 mm² wire, reinforced insulation, conductor diameter 0.9mm, outer diameter 3.5mm, size 7x6.5mm^2, drill diamater 1.2mm, pad diameter 2.7mm, see http://www.metz-connect.com/de/system/files/productfiles/Datenblatt_312051_RT045xxUBLC_OFF-022759T.pdf, script-generated with , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block WAGO 804-124, 45Degree (cable under 45degree), 16 pins, pitch 3.5mm, size 21x7.6mm^2, drill diamater 1.2mm, pad diameter 3mm, see http://www.produktinfo.conrad.com/datenblaetter/550000-574999/556441-da-01-de-LEITERPLATTENKL__PTSM_0_5__8_2_5_H_THR.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_4Ucon THT Terminal Block WAGO 236-306 45Degree pitch 5mm size 20x9.8mm^2 drill 1.3mm pad 2.5mm terminal block RND 205-00236 pitch 5.08mm length 12.8mm diameter 5.8mm Fastron HBCC Inductor, Axial series, Axial, Horizontal, pin pitch=85mm, , length*diameter=80*35.0mm^2, Electrolytic Capacitor, , http://www.kemet.com/Lists/ProductCatalog/Attachments/424/KEM_AC102.pdf CP Axial series Axial Vertical pin pitch 22.50mm length 26.5mm width 10.5mm Capacitor C, Rect series, Radial, pin pitch=10.00mm, , diameter=26mm, Electrolytic Capacitor, , http://www.kemet.com/Lists/ProductCatalog/Attachments/424/KEM_AC102.pdf CP Axial series Axial Horizontal pin pitch 12.20mm length 25.4mm width 14.7mm Vishay TJ5 BigPads L_Toroid, Vertical series, Radial, pin pitch=5.00mm, , length*width=7.2*3.0mm^2, Capacitor, http://www.wima.com/EN/WIMA_FKS_2.pdf C Rect series Radial pin pitch 5.00mm length 7.2mm width 4.5mm Capacitor C, Rect series, Radial.
